a buddy of mine currently drives a 90 integra with a complete 92 GSR changeover. Its got everything GSR.

Now my question is, He just blew his tranny and put in an LS tranny.
When he shifts into third he isnt in Vtec because we're thinking his gearing is off. He shifts and its at 5000 and vtec isnt untill 5500.

So we think ECU would cover it properly.
What ECU do we need???
and how would I Install it ??? plug and play? or more.. etc.

Thanks.

PS - I know *** all about wiring. Well I know small **** but havent done a swap or anything like that. so ECU knowledge isnt my department.

 

the 1992 gsr is the b17a, which doesn't have the butterfly Intake manifold... Therefore pick an OBD-1 VTEC ECU.

I don't understand why you think an ECU would fix the gearing problem. LS trannies aren't known for wonderful gear ratios... That's that. If you need better gear ratios fix the GSR tranny and use it instead.

Now, you could CHIP the ecu he currently has and lower the VTEC point but you're not fixing the problem... simply covering it up... And besides, lowering your vtec point isn't always a performance "upgrade"... You can't just blindly lower the vtec point and think it will make the car faster. it won't.

HTH,

yes, changing the ecu wont fix the gearing problem, and lowering vtec somtimes causes you to loose alot of hp and make the power band dip. you could get some valve springs and retainers and chip your ecu to rev 9000rpm, then when you shift, you will be in vtec : P fixes your problem, and gives you more power
