which is better? i know the JWT raises the redline to 7,000rpm. does gforce do the same? also, has anyone run the 1/4mi faster as a direct result of the ECU upgrades?? is it really worth it?

 

G-Force ECU does not raise the rev limiter to 7,000. I ran a before and after on the ECU and it took off .5 sec from my 1/4 mile. I have the G-Force. I think its worth it.

 

What is ur before and after 1/4 ET??

 

search.. there have been 5 million posts on battles in the differneces in ECU..

hey Nightrider.. what was your 1/4 before and after the ECU.. because to teh best of my knowledge your best run is 15 secs.. and Ben ran 15.2 with teh same year car and transmission and he didn't have 3/4 the mods you have.... so if you are hitting 15.0 and you did 15.5 before.. thats a driver error.. not the ECU

 

His stock run was 16.3 if that helps any. I don't know if he had some mods before testing the ECU though.

does it make a difference if my car tops out at 7,000rpm? maybe the JWT ECU has an added benefit.

 

If you get one, get the JWT...you'll never regret it. Remember, neither will work optimally except on '95 and '96 cars.

 

No fair!!!! When will we 97-99 max owners get an ECU that won't keep our engine check lights on or give us the performance increase the 95 and 96's get?

 

do you get a CEL immediately with the installation of the older ECU or does it trip a couple days later? can i keep resetting it if i don't wanna see the yellow light at all times?

 

as soon as we get manufactured red/clear tails

 

There is really no benifit to raising the redline, ubless you get the Variable Intake, then the higher redline would be very benificial.

I wish I could get an ECU

 

Did you ever dyno your G-force ECU? I'm planning to dyno mine soon and compare it against my stock ECU...

 

Ok, but at least, the red/clear tails can be done on your own. If someone on here knows how to upgrade their ECU without buying one from a manufacturer, please pass down the knowledge.

 

VQ, I had a JET (not JWT) ECU for a few days. Its a long story, but the guy said it was a JWT (which is what I wanted) but it turned out not to be. Anyways, the rumor on the boards is that the JET ECU does nothing for performance. I can say that is DEFINATELY a farce... the JET ecu felt awesome in the midrange RPMs, I only had it for 2 days, but I miss it. The only reason I sent it back to him is because I need the 7000rpm redline to go with my VI.

So what I'm saying is this, people claim the JET ECU does nothing and both G-Force and JWT are far better, if thats the case, I CANT WAIT to get my JWT ECU because even the cheaper JET ECU felt friggin awesome from 3000-5000rpm.

BTW the guy is still selling the JET ECU I think, search the for sale forum for "ECU" and you should find it. His name is Goliath, hes in Georgia. Nice guy to deal with, even sent me my money back right away when I informed him that the JET ECU was not what I wanted.

As for G-Force, BEJAY1 has back to back dynos of stock and G-Force ECUs on his cardomain page, he saw good results even on his 97.

 

basically the whole reason i wanted to post something on this heavily debated topic is to hear from someone who runs the track consistently before and after the mod. i would like a "i ran at least 6 times before and after and in those last 6 outtings i've been running CONSISTENTLY X mph better and X tenths off my times before the ECU mod" review of the product..so far, everything i've heard were one time dynos and lucky runs at the track! useless information.

 

I can't think of anyone who drag races often that has any ECU. I agree with your assessment of the lucky/flukey track runs from inexperienced people, but you don't feel a back to back dyno is good empirical data as far as power gains are concerned, (not 1/4 times). BEJAY1 dynod 4 times that day, 1) stock muffler + stock ECU, 2) stock muffler + G-Force, 3) 5th gen Muffler + stock ECU, 4) 5th gen muffler + G-Force.

 

i just want to run faster than my 14.32 with a bolt on mod. the car is good for it. i just have to find someway to drive it or mod it better. the best launch i've gotten from my tires was 2.1..maybe i'll play with the higher rpm launches.

 

I know that feeling... I've been stuck un 14.4s since November You've been stuck in 14.3s for about that long right? Its annoying because I get more and more mods, but the weather gets worse and worse too

But, the VI goes on with bolts

Honestly I don't think you are going to see any better 60' times unless you do different tires. You consistently have the lowest 60' times of any max I know of on street tires. There's a physical limit to how quickly you can get off the line and I think you are REALLY close to it. 2.15s are awesome. I usually pull a 2.18 once a night and the rest are 2.20-2.26

 

I go quite a bit...but I am an auto and I never ran my car at the track before I had all my mods, so I am no help. Sorry. I did get a good butt dyno reading when I installed it though.

 

You don't happen to have access to a stock ECU do you?

 

I would actually like to try that sometime, maybe if I can find an ecu to use I will.

 

putting a5th gen muffler on a 4th gen is a waste of time and money, you even lose torque with it. Has been proven...

 

 

two people ran with the G Force Consistently and it was .2 and 2mph.. thats cheston and Confused.. ask confused why he sold his ECU..

 

No mine are way worse than his(60' times) my tires suck big time and I'm still learning how to race on the track.

 

Before you make bold statements like that, please know what you are talking about. Go to Bejay1 's homepage and take a look.

 

right, been at 14.3 for a while. i forgot to mention last night i got a 2.10 (have to check my timeslip again) 60' but i still ended up running a 14.36@94mph. i'm beginning to wonder about my UDP. this is the first time to run it, but 94mph sounds kinda slow to me. i'll have to run more to confirm if my trap speeds have reduced as a result of the pulley. why would my traps lower because of a pulley though? i've been psyched out because i heard someone here mention the pulley reduces trap speed, but it doesn't make sense to me so i still bought it.

 

 

A little OT, but if I were to swap say a 97-99 engine in my 95, would a JWT still work on my car?

 

only if its a 97 engine..

 

oops, that was a typo..i meant 14.36 not 13.36 lol. i'll edit that asap.

 

Love everyone speaking up for me
P.S. Yesterday's auto-x course favored my powerspots. I think I smoked STS, STX, and even all the WRX's in DSP. Quote of the day "How much power you got in that thing". More when the results are official.

 

bejay, i forget whether i asked you or not but does the CEL come on immediately with the older ECU or does it take a few startups for it to set off the CEL? i wonder if i can keep resetting the ECU in order to get rid of the CEL.

 

When I install the modded ECU the MIL stays off for a couple of trips (say 50mi?). Then it lights. I swap the OEM ECU and it goes off right away (no reset or anything on my part). Then the modded ECU goes back in and were back to the beginning.

P.S. Usually I don't use it daily cause I never know when I'm gonna be in a shop. Forgot how potent that thing is - even the litl bit on a '97

 

uh huh... take a look at his dyno sheets and then edit your post please.


VQdriver: a 2.10, holy crap man, what tires are you running anyhow? I know you are a big advocate of the low RPM launches, I've just never gotten them to work for me.

As for the UDP I doubt thats why your traps were down... even if the UDP doesn't help, I cant see it losing the 15 or so hp it would take to drop your traps 2mph. What were the conditions like, and what were your AVERAGE trap speeds before and after the UDP?

 

My trap speeds went up with the UDP and my ETs went down (~.15 and 1.5mph). As for 60 foots, I wish I could get 2.1s. I just don't see how it's possible at my track. I've experimented with all kinds of launch rpms (1500-5000rpms) and clutch slips and I've found that 2600-3000rpms seems to work the best for me. Of course, the best 60' I've ever had is a weak 2.24 so who am I to offer an advice In hot weather, my car is just a dawg and it can't get out of it's own way in the 60'. Once temps get past 80 degrees, my car is stuck in the 2.3Xs.

dave b, nealoc, vqdriver could you guys help me out in looking at my timeslip here...i ask you guys because you have great knowledge when it comes to racing i have noticed.
anyway...
my timeslip reads
15.409 et 1/4
.5857 reaction
91.397 trap
2.304 60'
6.631 330'
10.10 1/8
13.01 1000'

i am stock except for a JWT intake. i launch in the 1500-1900 rpm range. where am i hurting? it appears to be up top but i would like to see what your guys analysis thinks.

thanks

 

nealoc, i'm using BFG HR4 215/60/r15 on 95SE wheels from non other than maximarider's old car. i bought them over a year ago and they're nearly balding, mostly because my camber might be a little off. i deflate the fronts to 15psi on a hot day. it works great when i launch at 1,500-2,000rpm. i'm willing to try higher rpm launches to see if it changes any. to me, 94mph is a little on the slower side. my car usually gets at least 95mph. 96.8 is my highest to date. temps were close to 90 and very sunny/humid, but that hasn't stopped me from running over 95mph in the past. i guess it depends on the clutch and engine temp and not the actual air temp outside. i want to test and tune in a cool evening! i'm sure the car will surprise a few stock mustangs in the crowd lol. as for the UDP, i must test it a few more times. once on the track isn't enough. especially when conditions don't allow for good runs. i want an ECU now!
