I should be able to get mine real soon. I got some questions though. I read a post about that you can really feel the difference in 3rd gear. Could you feel a difference in 1st gear and/or lower rpms.? And how big of a difference is it? How much of a power increase does it feels like? Much more than let say a CAI? Thanks.

no cai but i posted my track results in the gen forum. even after i had it installed i didn't feel any difference. but then again my max is stock. just an opinion.

i read in maximadriver.com forum from Chebesto that there is a big gain. About 30 extra HP. VS. CAI around 5 hp. So judging the ECU, you will feel the speed. Its a better mixture of gas and air mixture so you will gain the most HP out of your maxima! I'm Waiting for them to make one for my 1998 maxima.. I talked to them but its not going to be for awhile.

95greense,
Well that really sucks!!
It bothers me because I'm supposed to send my ECU in late
March.
If I'm spending 425.00 I expect results.

Are you sure it was done right? Have you called and asked
WTF?

Let us know.
E.

O.K. I just noticed 95greense has a G-force ECU.
I'm going with UPRD.
Maybe G-force sucks I dont know. But I've heard good things about UPRD.
E

the g-force ecu is the uprd ecu. chebosto posted a awhile back that g-force was the original creators of the ecu upgrade but they were in the process of being bought out by uprd. things fell through so now it's just the g-force ecu.

i'm not sure if calling will help though. i don't recall them saying that they gauranteed results. i just wanted people to know about my results. personally i do feel ripped off but i'm willing to see if a y-pipe will help.

i would be hella pissed...

Well I thought I was going to send mine in next week? But WTF I dunno now?

who knows though. somebody said that they gained 2 tenths with the ecu but he also said that he added a 2K muffler and shift light. but then again, i got my ecu programmed on a saturday. you know how things made on fridays and saturdays go. anyways, don't base all your judgements on my experience. just know that the ecu may not be all that it's cracked up to be.

Wow, if 95greense is right, I'm worry. I was skeptical about the gains it would provide. I was thinking either getting this ECU or Don's VB upgrade. Now, I'm leaning more towards Don's VB upgrade. The ECU can wait. I want to hear more people's thought on it first. If I want to get the ECU later on, I think there will be another group deal later on. So, no biggie. I mean if you spend over $400 for the ECU, I would think you should feel a heck of a difference.

you do know theres a 30 day money back guarantee....

26 days and counting.......

btw..i think the ecu wont work at its best w/o breathing mods..cai, ypipe, blah blah..

Maybe they shipped you a regular ecu by mistake and the chip is not modified.

How do you know when you're supposed to send in your ECU?

i wish that was the problem nismo, but i went down to g-force to get it done. anyways, i'm gonna get the y-pipe soon so i'll hold off before i send it back for a refund. if the y-pipe is the problem than i should expect almost .5 sec improvement when i install the y-pipe. 2 tenths from the ecu and 2 tenths from the y-pipe and another tenth from the intake given that it has a cumulative effect w/ the y-pipe. does that sound right?

buss95max: there's a 30 day on the ecu? i'm really thinkin bout returning the ecu and gettin a y/b-pipe instead. are you sure bout this?

People, people...there is no way the UPRD mod makes 30 HP...sorry, but that's a bogus claim just like the K&N air filter commercial that says "up to 20 more horsepower"...well yeah, maybe...on a Viper it might make close to that. But we're talking about 1/3 the displacement and less than half the horsepower to begin with...so a more likely estimate is 6-7 hp, which we know it to provide. I think 10-12 is reasonable to expect. And yes, you would be able to feel that if you were familiar with your car. However, it's not a bolt-on turbo! It's not something that's gonna whack you upside the head and make you think you can conquer the world. It's just yet another step in extracting the full potential of your car. And that's why I like JWT...why is no one considering their upgrade...they claim 12 HP and 15 lb-ft of torque over stock peaks...that makes more sense to me, and seems to be trustworthy. UPRD just isn't professional, if you ask me...their site didn't make a solid impression with me. So you save a hundred bucks or so...I'd rather deal with someone honest.

GForce Engineering (UPRD) ECU <--- dental stud (lurker)

JWT ECU <---dental stud (lurker)


hehehehe

I think you can send it in right now; I think Robert is out this week but next week he'll be back.

And just to think everyone and there Mama was ripping on me because I said the UPRD ECU would most likely do little for the VQ. It's interesting that many people are now actually thinking that this ECU might not be doing what it claims. Everyone told me to shut the hell up until track results were posted. Well here's the proof...Confused only ran .2 better with the ECU, muffler, and a shiftlight and 95greenSE improved by less than .1 with a loss in trap speed. The gains that were quoted would easily lower a Maxima's et by at least .4 and gain 3mph. I see no proof of that.

I warned people to wait on the ECU until they could track test and dynojet Nabil's car, but no one seemed to listen and the GP date got close. I don't know everything about car's and performance (not even remotely close), but looking at all the data (dynojet, Clayton dyno, power quotes), it was clear that this ECU wasn't gonna meet it's intended gains.

Nissan went to great lengths to extract the most hp and tq out of the ECU while keeping it emissions legal. I don't see how tweaking an ECU is gonna gain you 10-20-30 hp. This isn't a turbo car in which you can adjust the wastegate and make huge gains. It's a NA car with very particular fuel and ignition tables.


Dave

If the JWT can make the output, why cant the UPRD/GF? The dyno (pick one) shows gains. How much is trivial. The gains are there. There are plenty of other posts where guys can feel it, Im just one. And as for the website being unprofessional, so? JWT has been promising the 4th gen turbo for YEARS AND YEARS .. how f'n professional is that?

While i wasnt jumping up or down or anything, i could feel it. I have 18s, and an auto. Im not expecting to drop a full second or anything.

And for someone so **** about details, the .2 might have been warmer, colder, whatever. Nothings ever the same, unless he did all those boltons on the track within like 10 min, with his car flaming hot.

I don't really want to take sides on this, but whoever is not satisfied (and drove to GForce/whatever to get their ECU done) could have contacted Cheston to try his out. He offered it. Its not like the offer wasn't out there for socal guys to go n try it before you buy it..

This is my first and hopefully only post regarding this issue. The gains EXIST. Even on a dynojet. Even at lowest 10hp, or whatever. Sound like JWT? Fine, its still cheaper. If you want to go another way, then by all means, do it.

Hey Dental.

how is JWT more professional than Gforce engineering?

you call JWT more professional because they charge $600 for an Ecu upgrade that can be priced as low as Gforce engineering's ecu AND still make some profit?

you call Gforce engineering unprofessional because they went out of their way to program ecus for us Maxima guys, when they didn't need to?

you call claiming Turbo kits and promising ECU upgrades for the past three years as "Professional"? oh yeah. that's JWT by the way.

have you EVER been to JWT OR GForce engineering? Then why don't you come to So Cal and i'll show you Gforce engineering in person. They have one of the best ECU programmers in the US working for them, and a helluva lot professional than JWT.

just because "Jim Wolf Technologies" is a name you've heard of, doesn't make them more professional than GForce..

Stop talking outta your butt if you don't even understand what youre talking ABOUT.




[Edited by Chebosto on 03-08-2001 at 03:05 PM]

do you guys think it would prove anything if i were to put my ecu into another max and see if he has any improvements? buss95max runs at LACR also and i don't think he got his ecu yet. he has a 95 auto max also. it might clear up whether or not i'm just a crappy driver or if there are any real gains. what do you guys think? what bout you buss95max? wanna try out my ecu before you buy yours?

Calm down...you're all hot and lathered for no reason. You like your UPRD ECU? Great! More power to you. Literally, it seems. My point is simple...it has nothing to do with "having heard the name 'Jim Wolf' before". I honestly hadn't heard of either until a couple months ago, when I finally decided to start modding my Max. And THIS is the point...UPRD claims gains of 30 HP for their ECU upgrade. That is a flat lie. Maybe they provide the same product for less money...maybe they don't. But they ADVERTISE it as better. And there has been no proof of that whatsoever, other than screwed-up dyno's. I'm sure they have some quality people working for them. I never denied that. I'm just saying that I'd rather deal with someone who tells me exactly what I'm getting, and doesn't make ridiculous exaggerations on what their product can actually do. If I have to pay a little more for it, so be it. Maybe the end result is the same. Both companies are certainly in this for the money. Don't paint a picture of UPRD as some martyr who's doing society good by "sacrificing" to make us an ECU. And I won't do that for JWT. I'm simply saying that JWT advertises and informs with INTEGRITY. Nothing more, nothing less. Saying a product is coming in the indefinite future does not negate that. UPRD did not inform with integrity, in this case. Oh, and while JWT does charge $599, you can get it through Stillen for $549. Just wanted folks to know. It just seems to me that there have been an awful lot of folks who are or were affiliated with UPRD posting to this message board and waxing eloquent about how "incredible" their product is. Sorry, but real-world people and real-world time slips are what I want to see. I have a feeling that the products are in actuality very similar. We just have differring preferences of the type of folks we like to do business with. If it's worth the money you save, go for it. I'll stay where I'm at. Sure footing on moderate gains is better than rocky extremes of major gains claimed and minimal gains evidenced. But that's just my opinion, and I'm entitled to it, as you are yours.

Alex

We all have our preferences, and there is no reason we should be bashing the others.

One prefers JWT; the other prefers UPRD.

One prefers Cattman Y-Pipe, others prefer Stillen; some even prefer the newcomer Warpspeed, who has far more reasonable prices with quality unproven. Noticed I said "unproven" because nobody's used the pipe for a lengthy amount of time (36 months). Does that make Warpspeed a worse choice than the others, I think NOT.

Come on! Bashing is completely uncalled for...

Am I still going to get my UPRD ECU because I am on the GP? OF COURSE! $425 for an ECU is a bargain, and I am pitching in $50 for an additional chip to be NOS ready!

We are enthusiasts, not bashers.....

Exactly. Which is why I'd like to stay outta this. But for 2 pages worth of this thread i didnt see anyone defend the product, and I dont think thats fair for the guys who did the work in gettin the product researched and made, and organizing a group deal.

Its not like everyone has time to go dyno 800 times just cuz the org wants it. Of course they want proof.. its not their money, its not even their time. Pretty inconsiderate demands, i thot we were here to share.. Some ppl have gone out of their way to do this, maybe others should show a lil support and try it themselves.

ur talking to the guy that gets 16.4 stock @ 3000 ft :wink:
yeah im down to try out the ecu. when?

95greense IS NOT A BAD DRIVER...you guys shouldnt diss him just cuz hes not getting "results" from the ecu. he is STOCK..pretty much anyway. im sure with more breathing mods he'd do better.

anyway about the track we run at...its the los angeles county race way...ive heard people say its 3000 feet up.
it seriously affects ur time. people that will run mid-high 14s get 15s up there. its usually 30-40 degrees(freakin cold for us sunny la kids) when we run.
if you guys want to know the exact temp check out http://www.lacr.net they got a link that shows past weather conditions.....

k listen with don's VB and the ecu and all the stuff i have installed in my car it slams even harder into gear.
1st and 2nd have so much dam power after u pass 3500rpms.
You will get best result with y-pipe and intake,
listen to me i have it installed in my car and dam the car needs this mod, It revs up faster and pulls like a beast u guys can keep talking your **** about the UPRD ECU and say the web page that cheston has up about uprd ECU is all bull **** well its NOT. It does like cheston says it does if u dont want to listen then dont well IM HAPPY WITH MY UPRD ECU!!!!

SORRY BOUT THE CAPS BUT MY KEYBOARD IS BUSTED AND WON'T TYPE LOWER CASE.
ANYWAYS ITHOUGHT I'D THROW IN MY TWO CENTS. LET ME START BY SAYING, TRUST ME GUYS I WANT TO BE A BELIEVER. IF STICKING MY ARMS OUT THE WINDOW AND FLAPING LIKE A BIRD WOULD HAVE SHAVED SOME TIME I WOULDA TRIED IT. I'VE SAID IT BEFORE AND I'LL SAY IT AGAIN. I HAVE A BONE STOCK AUTO MAX. MAYBE THE ECU WON'T WORK FOR MY SET UP. MAYBE LIKE EVERYTHING IN LIFE THIS IS A "RESULTS MAY VERY" DEAL. I WAS REALLY BUMMED AFTER SPENDING 5OO BUCKS AND NOT GETTING ANYTHING. I'M SURE THAT EVERYONE CAN UNDERSTAND THAT.

ANOTHER THING.I AGREE THAT I'M AN INEXPERIENCED DRIVER AT THE TRACK. BUT IF NOTHING ELSE I'M CONSISTANTLY BAD. I HAVE ABOUT 40 TIME SLIPS SO FAR ,AND WITH THE EXCEPTION OF ABOUT 5, I'M ALWAYS WITHIN .15 OF MY BEST TIMES. SO I FIGURE THAT EVEN THOUGH MY TIMES SUCK THERE SHOULD HAVE BEEN A GAIN IF THERE WAS ONE.

I WAS HOPING THAT MY EXPERIENCE WOULD HAVE BEEN USEFULL INSTEAD OF STARTING A ***** FLEXING COMPETITION. I REALLY APPRECIATE ANYBODY WHO'S WILLING TO GIVE ME ADVICE LIKE DAVE OR PEOPLE WHO ARE TRYING TO HUSTLE FOR NEW PARTS FOR US LIKE CHESTON. I'M JUST A NEWBIE AROUND HERE SO I'M WILLING TO TAKE ADVICE FROM ANYBODY. IF DAVE SAYS THAT MAYBE I SHOULD TRY WASHIN MY CAR WITH HOLY WATER AND ONLY DRIVE NAKED, WHAT THE HELL I'LL GIVE IT A TRY. IF CHESTON SAYS THAT THERE'S A NEW ECU THAT LOOKS REALLY PROMISING I'LL GIVE THAT A TRY ALSO. IF IT KNOCKS A TENTH OR TWO OFF I'M A HAPPY CAMPER.

ABOUT G-FORCE¡C DID I HAVE A GOOD EXPERIENCE WITH THEM? I DON'T REALLY THINK SO. I WAS BEING TOLD WAY TO MANY CONFLICTING STORIES. I EVEN CALLED ERIKS RACING TODAY TO GET G-FORCES NUMBER AND THE PROGRAMER THERE TOLD ME THAT G-FORCE DOESN'T EXIST ANYMORE. IT WAS ONLY WHEN I TOLD HIM THAT THE THE GUY WHO PROGRAMED MY ECU TOLD ME TO CALL IF I HAD ANY QUESTIONS THAT I GOT THE NUMBER. EVEN THEN THE NUMBER RANG 20 TIMES WITHOUT AN ANSWER AT 2 IN THE AFTERNOON. IS THIS JUST MY OPINION? ABSOLUTELY. BUT I DEALT WITH THEM FACE TO FACE SO THIS ISN'T JUST ME MAKIN STUFF UP. DOES THAT MEAN THAT THEY'RE A BUNCH OF UNPROFESSIONAL CROOKS? I COULDN'T SAY YES OR NO. I'M JUST RELATING MY EXPERIENCE.

TO SUM THINGS UP, I'M SORRY MY EXPERIENCES DON'T MATCH THE GLOWING PRAISE THAT THE ECU HAS GOTTEN SO FAR. BUT ISN'T THAT THE POINT HERE? TO GET BOTH SIDES OF THE STORY WHEN POSSIBLE? I JUST DON'T UNDERSTAND WHY THINGS HAVE TO TURN INTO PISSING CONTESTS AT THE DROP OF A DIME. JUST A NEWBIE'S POINT OF VIEW.

BUSS95MAX, EITHER WEDNESDAY OR FRIDAY OF NEXT WEEK IS COOL WITH ME. JUST LET ME KNOW WHEN YOU WANT TO GO AND I'LL SHOW UP.



[Edited by 95greense on 03-09-2001 at 12:38 PM]

95greense....

im going today.....try to make it if you can...

laters man..

imma try that 25psi with the front tire thing..

I knew the excuses would come when the ECU didn't perform. 95greenSE was there when they programmed his ECU. It may give you a .1 or so in 1/4 mile, but hell, my ets can vary by .2-.3 and a few mphs between runs. I was told this ECU will perform and with the power quoted it should perform quite well and should be easily noticeable. It appears that this ECU doesn't do much and the same could be said for the JWT. Why do you guys think Stillen never got involved in this in the first place? It didn't produce the power that they wanted.

Tell me, what aftermarket ECU for any NA 95+ car actually performs and puts down good power? Why would a Maxima ECU be any different? In a SC/turbo car the gains are there. NA they're not.

Cheston and Nabil should be congradualted for going through all this with UPRD/G-Force, but they shouldn't have been so quick to "believe". The tides are shifting and people are now doubting the performance of the ECU. All this could have been avoided if Cheston and Nabil would have 1/4 mile track tested and dynoed. Cheston did dyno and his dyno shows his car making minimal power gains with the ECU. I've seen bigger dyno differences in power with my car between two runs in 5 minutes then he did comparing ECUs. His excuse was his tires were slipping because they were wet. I think his dynos show the truth and I don't think his tires were wet. Believe me when I say this, I am not attacking or flaming Cheston, I just wanted to see more conclusive proof and he took it WAY TOO personally.

When I did the Poorman's CAI, I didn't scream that the car was faster. I said the car felt the same vs the HKS intake. I dyno and track tested the Poorman's CAI to get the "truth". I invested my money to test for everyone and get the numbers (now I'll probably get flamed for showing that a POP and CAI intake do little to improve performance). I didn't want to go by my butt-dyno because it's not accurate and I sure as hell didn't want to be responsible for making people's car's slower with this mod. If you develop a mod and you say it performs, make damn sure you can back it up.


Dave

I think on of the major car magazines did a test on ecu's on n/a cars and found that on one of the cars it actually decreased the 1/4 mile time, I cant remember what issue or what cars, but Ill look though my stack of magazines and see if I can find it.
