yo man, what did you think of the JWT ECU. . . someone said you had it. i searched and couldn't find anything. . . thanks bro

 

Yes, I have had had it for 18 months now. It was instant power, especially in the higher rpms.I really notice it from 5000 RPM and up to redline and beyond. I try not to go over 6500 rpm. Some people have asked me if it was worth the $500? I think so. It is not as noticable as the y-pipe/CAI mod. If you going to buy one, get the CAI and Y first. I asked them to customize mine because here in MN we don't have emisson testing. Not sure if they did. Personally I rate it as #3 in power/performance gained behind before mentioned mods.Maybe a group but will get the price down a little.Hope this helps.

Can't you have your ECU custom programmed to your mods from JET for like 200 dollars less???

 

I haven't heard of that before. I have heard that if your an electrical engineer it's not all that tough. Some one else must know.

that the Y-pipe and CAI were better than the ECU?

I got the ECU as the last bolt on for my car, and I felt that it made about as much difference as all the intake/exhaust (cai, Y, RT cat, catback) mods put together. My ranking of mods would go as follows:

1. ECU ($550)
2. Y-pipe ($350)
3. CAI ($200) (better than UDP only when combined with Y-pipe/exhaust)
4. UDP ($125)
5. Catback ($300)
6. RT cat ($200)

Bang for the buck I would say is a tie between the Y-pipe and the ECU, but I did notice better gains all across the powerband with the ECU.

 

But the thing is, you need to make the ECU your last engine mod... When you order it, you tell them what mods you've got, and they supposedly program it based on those mods, so that it'll run better than a "general performance program"

each reprogram is $100, so you don't want to do that half a dozen times.

 

You can, but do you get the same gains?

Most have said no. Dyno #'s would be nice tho. Anyone have JET dyno #'s?

 

didn't some guy say he gianed ~12hp, or was that with a Superchips ECU??? he was on the other BBS, he made this one out of place post about how great the chip was than disapeared.....frekaing wierdos!

 

Yeah, he was talking it up pretty well, but I have yet to see any paper proof.

 

I remember him... he was talking about the Superchips crap or something. 12hp? Is that reasonable? Could you really get 12hp from any chip?

 

U could gain 12hp but it varies from car to car. I won't say any names (J. Fobart) some with a 90se auto with intake and dinan (superchips ECU) ran me in my 87se auto with K&N panel + timing advance. We were dead even from 20-75mph but in 3rd gear he did start to pull slowly on me. However I've seen the JWT ECU dyno 12hp gain in a 4th gen vs the stock ECU. I remember Vitaly a long time ago had a superchip ECU that gained around 10-15hp on a dyno. It doesn't really matter if you order the JWT ECU before or after bolt on mods. You can get slightly better torque gains by bumping the base timing 1 degree wiht the ECU.
