how much hp should be expected from a ecu upgrade and how well does it work?

 

yeah how much for a gforce i have one of those....i can feel a huge difference after 3k but i never knew exactly how it worked or what kind of gains to expect

 

JWT about 10-15 hp. GForce maybe 5-10. JWT is nice...it raises your rev limiter as well to 7200 RPM. GForce doesn't. Hope you have a '95 or '96 however...they only make them for those years.

 

Uhh, G-Force ECU's are more aggressive than JWT. You'd better switch those numbers around.

 

99 ECU where art thou?!?!?

so what u are saying is that its worth to buy the ecu for the car.. its gives u a noticeable amount of power

 

no one respects us

 

JWT raises it to 7000, not 72000. I noticed quite a large difference with my JWT ecu. I have heard better things about JWT than I have about GForce.

 

JWT raises the limiter to what you tell them to raise it to. Most people do 7000, Neal did 7200. Your valvetrain is your own.

 

well i have the gforce and i can tell you its more noticeable than my y-pipe was after 3k rpms

 

tell me about it...B@stards

I've heard that G-Force is a bit more agressive in their timing/fuel than JWT is. Anyhow the ECU is sweet, Requin6 dyno'd his a few months back you might be able to find it but without the search it will be difficult. He got like 8 peak hp and 10 peak tq, iirc he got about 10hp and 12lb tq in the midrange rpms.

 

i talked with the gforce people on the phone and they said something about a 20lb tq gain at 3400 rpms...i wasnt too sure on that one but it feels good and noticeable...they wouldnt quote HP gains though. Im dying to know what i gained

 

i believe it could be very close to that. i rode in VQdriver's car a few days ago. he has GFORCE, y pipe, racing pipe, catback, intake, UDP for power mods. his car is tons faster than mine. low end grunt in his car was amazing!! he ran 14.05 on street tires! BTW he has a '97

 

Can i get a modified ECU for my 1997 maxima to increse the HP?

 

im a 97 too but im an auto....i have everything he has but a racing pipe and even my g/f noticed the ecu.....and we all know girls usually dont notice these things

 

check those eyes son. make sure you put them in right...look RIGHT ABOVE YOUR POST!!!

 

how much is a 96 ecu? i'm guessing this is still the only way to do a ecu mod. in a 97+, correct?

 

i have a 95 in my 97

 

does your friend have a check engine light....i get rear heated o2 with mine

 

I also would like to place an order to get a modified ECU for my 1997 maxima to increse the HP?

 

Just to add some info. My '96 G-force ECU in my '97 gained +8 fwhp/+10 fwtq @ 4500rpm. all bolt-on's but no MEVI.

 

thats all....its not bad but i feel it more around 3500 then 4500. I feel more gain up top from the ecu than the y pipe

 

True enough.. anyone talk to Jim Wolf's people about getting us an ECU? I've tried.. no response.....

 

I'm not quite sure, but if I decide to go w/ MEVI, is the JWT ECU a must have?

If the GEFORCE ECU is a better power adder than the JWT ECU and it is also cheaper... then why aren't most people (if not everyone) getting the GEFORCE?

 

you can click the link in my sig to check out the mods that accompany the ECU. this is a great mod and well worth the wait and money. with the VI its a monster.

They dont make the G Force ECU anymore, IIRC. I have a used one for sale, it helpd be allot! Click the link in my sig,

 

Why cant someone make one for 97+ already.

 

96 works in my 98 just fine, I do get a CEL, but I prefer function over form, so the light dosent bother me for the gains.

 

hey i have the gforce in a 97...what check engine light do you get? Ive been getting rear o2 sensor. I was just wondering if you get the same error from the older computer

 

thats because with the JWT is raises your redline to whatever you want it to be and with the mevi the car will actually make power up that high. If you have no plans on getting an mevi and can find a cheap used gforce like i did then go for it

 

I got a JWT one and cant wait to get the MEVI because I hear "ALL THE HYPE" about how the ECU isnt that much worth it unless you got a MEVI..

 

oh i think the JWT ECU is definately worth it without the MEVI. its just a great combo when you do add the VI.

Wasnt really directing that right at you...But yeah I can feel the ECU definitly. Nice setup under the hood. Cant wait to get mine.
