Hey I was wondering if anyone is still into these? I remember about a year ago everyone was talking/wanting one ... anyone out there still buying them? If so, they worth it?

Judging from your sig pic, you have a 95/96 ... so yes, there are several options for ECU upgrades for your car.

 

I know there are options for my car with ECU upgrades...im just looking for fed back, from people that have them

I could be **** and tell you to SEARCH, but I won't. I'll save you the time and sum it all up:

JWT=GOOD

ALL OTHERS=CRAP

Don't mean to offend the G-force folks, but there is no proof that any ECU upgrade but JWT increases power at all. JWT is good for 10-20 hp, depending on what other mods you have done. www.jimwolftechnology.com

Will run you nigh unto $600, but very worth it in my opinion if you're looking for that little extra oomph and already have intake and full exhaust.

 

Thanks alot man, thats all i wanted to know...and hell if anyone reads this and they have one, tell me how much u like, or if you dont....anyone selling theres by the way?

Eh? Back to back dynos showing torque gains upwards of 13 ft-lbs over the stock ECU aren't proven gains?

 

ehhh, maybe...but bottom line is that there's a reason why a JWT ECU is on your "up next" mod list rather than G-force. And it ain't cost.

 

All I can say is that if you plan doing this and have a 95-96, try finding a spare ECU with the same serial code as yours or just send yours in. I tried putting a G-Force 96 MT ECU in my 95 MT, and got ECU codes up the wazoo. Luckily was able to return it.

 

and still nothing for anything newer than 97 heh.

 

Got me there...

 

I thought G-Force is more aggressively tuned and actually provided more gains than JWT? Has anyone ever seen a dyno for a 95-96 5 speed w/ a JWT ECU? I know they dont have one on their site.
Thanks

 

Where'd you hear that? I just purchased a JWT ECU and I'd be quite angry to find out the G-Force is more aggressive.

 

I know JWT is better I just want to know if its worth me spending $565 from Cattman when it might be a waste ??
Yea ? What does it do to a 5spd any way ?? It cant change the shift points at all ?? Please some more feedback from people who have done this..
I have alot of money that is burning a hole in my money jar

It was a couple of months ago I was looking into buying it and I called Robert at UPRD and he said that the G-Force ECU will give you more gains than a JWT because they are more aggressive with their tuning.. I mean whatever that means.. maybe the timing or something.

 

I'd go with Jim Wolf. G-Force I got one last year and the ECU is hosed, I got this one from UPRD or whatever GD Cheston was doing. I've emailed the world about trying to get it fixed and I get no replies. So with this new ECU I am going for the Jim Wolf upgrade, they have been around for a while.

 

Well I guess UPRD would say that whether it were true or not, they want to sell their ECU rather than JWT. I hope its not true...

 

Yeah I am sure they would say that..I dont think its true..unless anyone has side by side dynos?? Or does anybody have a dyno w/ a JWT ECU?

 

BEJAY1 and I will find out in a few weeks whether or not there is a significant difference between the two.

 

Thank you buddy make sure you post that info thats good shat.
Thanks!!

 

I emailed the folks at jetchip a while back asking about an ECU upgrade for my 98 GXE. Here's what they said:

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.

I searched around on the forums and saw feedback from quite a few people saying this chip was worthless, so I decided against getting it. There is no other ECU available for this year.

 

Hey Neal. These could be awsome tests! Stock vs JWT vs G-Force. On both a 96 and 97. Kinda like Cheston's and Nabil's way back but more. You really want to share the results with everyone

 

What is it about a 97+ that they can't make an upgraded ecu?

 

Its not that they cant, its that no one has yet.

95 and 96 ECUs WILL working in 97+ cars, but you will get a check engine light. BEJAY has one in his 97, and Matt has one in his 98. They both work.

 

Hmmm...Wonder why no one has, I figured the demand would be sufficient.

 

I thought that they can't because of the 97+ is a 32bit ECU rather than the 95-96 being a 16bit ECU...?

 

Wire harness change from 98-99s that aren't federal spec.

 

Nobody has really givin an solid evidence to me speding almost $600 dollars on an ECU for my car...Does it do anything ?? what changes will I encounter ?? Better shifts with my 5spd ?? WHAT ??

-matt

 

Well YOU shift your 5 speed on the ECU. So NO on the shifts.
It changes your fuel mapping curves, it allows your car to run leaner in the high end.
It changes your Rev limiter from 6500rpms to 7000rpms (which is safe)
If you really want SOLID evidence take the time to do a search. there are only 254 some odd threads. Or perhapse take the intiative to write JWT, Cattman, Jetchip. Do some of your OWN research...

BTW-jump off a cliff....

I just wanted to see if you base all of your decisions on what strangers tell you to do.

Sorry to be an A-hole its 1:39am

 

Well I just jumped off a cliff in my back yard...and it hurt alot

Im a bigger A-hole ...its 1:44 A.M
