ECU Upgrade
I thought I would share an email I received from Jetchip.com regarding a chip for the Max.
"I have a 2001 Nissan Maxima SE Anniversary Edition automatic. I was wondering if you have a chip for my car. Do you know what the hp and torque gains are for my car? Any and all information would be appreciated."
Reply: "We do have an ecu upgrade available for your application. The ecu upgrade does require that the factory ecu be sent to us for modification. You must purchase the upgrade package before sending the ecu to us for the modification. Suggested retail is $399.00, and the part number is 65002. The ecu upgrades are all done per the application, in other words, do all the modifications you intend on doing before you get the ecu upgraded. That way the program can be set up for the specific modifications. Hp gains would be dependant on the extent of modifications."
Hope this helps someone out there.

How long??
Did they tell you how long it would take them to get it back to you?
Is it like the other ECU upgrades where they charge $600, and then you get a refund to make your price $400?
Glad to hear there IS something out there...thanks for doing the leg-work for us!

Here's some info I got from them on the phone:
They claim 15 hp at the wheels. I asked them to send me their dyno.
They say it is for a 97 and claim that they got the same results for a 2k+ but don't have that dyno - yeah right.
I asked him to mail me the dyno plot (he couldn't e-mail it to me) and told him I'd buy the upgrade if he sent the plot.
Won't give me back my money if results at my dyno don't match theirs.
ECU can be returned to stock during the 1 year warranty period. After that it costs $75 to return to stock.
The v-force product gives about 1/2 the results.
ECU doesn't change rev or speed limiters.
It seems to me that someone on this board purchased the jet upgrade? Anyone recall?

1) How could they say they got the same results for the 2k+ w/o a dyno sheet?
2) Okay have then fax over the dyno sheet for the 97.
I know if I GOT GAINS from an ecu, I'd be faxing dyno sheets left and right.

I explained the difference between the 97 and 2k, and he just said "well we got the same results."
I think I did this once before with them and they never sent anything so I never bought anything.

They did a custom ecu for your supercharger? Did they give the ignition timing map and fuel curve changes?

You DO know that ignition and fuel map changes are MUCH different for na maximas vs supercharged ones right? So if you are using a JET chip that is for NA maximas on your SC'd maxima that makes me VERY concerned.
ie.. you can't use a na JWT chip w/ a SC 4 gen because the timing maps would make the sc maxima detonate like crazy. Our ecus do not know what "boost" is w/o someone programming those varibles into the maps before hand.

Then for those with s/c, tranny mods, cams, pistons etc. they bump it to the proper levels.
(Just as examples.)
Thats basically what I'm trying to say. They do it per application there is no basic set up for a s/c or a na max. You tell um what you have dun. what the curves currently look like and they fix it.
My basic point is that those that have the chip mod, don't have much done. So the chip does not need much modifaction. So it may not be very noticeble as apposed to some one per say that would have a totally rebuilt engine.

The question is whether the damn thing gives 15hp to the wheels for a 2k+ stock or if they are full of it.
No money back guarantee, no dyno to support the claim.

It's funny how they can do a chip for a SC maxima w/o having one for tuning.
I think the reason it works for your sc maxima is because they didn't do anything to it. so is runs just like all the other sc maximas w/ stock ecus.
It's funny they can say "oh we can do that" like it's just some simple thing.
Sorry man, I maintain that they did zero to your ecu. I strongly suggest they fax you some dyno sheets right NOW, fax over the stock/modified fuel/timing maps or refund your money ASAP. Because from what I just read, they didn't do squat.
Don't get me wrong, I wish they did. Everyone here would be jumping on that shat bigtime.

"solid"? Did you get those ign/fuel/dyno maps from Jet yet? No one else has.

I've read more complaints about JET than good reviews. Of the chip makers, I say JET has one of the worst reps. That's why w/o solid information, I wouldn't trust them further than I could throw their marketing director.
So did you take my advice yet?

Here's my question(s):

What does it improve (HP, Torque, increased revlimiter, top speed governor removed, etc)? Can I see some dyno charts for a 2000 Maxima? What will it cost? And any other useful info you have for me, Thanks"

I have set numerous emails to them for the past month trying to get dyno results. I have had one emailed replied by them. But, when I ask the question, "I am going to buy your product, can you tell me where to send the cash?", they instantly reply. It's weird how they tend to check their email as soon as I send them that message.

Exactly! All Bs
V-force. WTF could it do when it only connects to two things. Stupid.
ECU: Abosolutely no info. Just the usual line of BS that fools no one.

JET has one of the worst reputations among chip tuners. Ive seen several back to back dyno tests where their program LOST power over the stock program.
Also, and this is the worst, JET "started" making ECU's for Neons awhile back. Well, one of the Neon guys who apparently knew his way around the stock ECU sent away for one as a test. The ECU they sent back to him contained the EXACT STOCK program! All they did was put a JET sticker on the case!
If half of what you hear about JET is true, Id say its safe to say they are pretty shady. I wouldnt waste my money with them.

I think it's a load of crap. Why would this think work, when they lie about their ecu? It's probably just same Venom crap that everyone that has sheit for brains went ga-ga over.

CHARGE IT ON YOUR VISA CARD...
There's no such thing as a no-rufund policy. If you use your Visa card to purchase the Jet ECU, you are guaranteed satisfaction.
If it doesn't work as advertised, you call up Visa & dispute the charge... Just tell Visa: "THE DAMN THING DOESN'T WORK AS ADVERTISED!!!"
I've returned items before to websites even AFTER their 30-day refund period expired! I basically called them up & said: "Listen, your product DOES NOT work as advertised & if you don't give me a full refund, I'll dispute it through Visa & you'll get a bad merchant rating from me"
...that was enough for them to issue me a FULL refund!
Someone with a modded-out 2k or 2k2 should charge it & dyno it. The good thing about this setup is, what are they going to do when you ask for a refund, re-program it to back to the factory settings?... HA! They can't do anything! But if they do ask to re-program it back, buy a second ECU (just in case they want to screw you & mess up the settings) and ship them the new ECU to be "re-programmed" back to factory settings. Then return the new ECU bac for a refund also & all is cool.
Any thoughts?
