I have a 1992 Integra RS with the stock PR4 ECU. I need a chipped ECU for a higher rev limiter (see sig) but the shop i'm doing business with, don't have any program for the PR4, they only have P75 programs, my question is simple, will the P75 fit? (since it's OBD1 and it's from non vtec integras.)

thanks in advance.

 

PR4/PR5 and P74/P75 ecus are similar. I would go ahead and try it.
I do this with Hondata, and its a 50/50 chance of it working.

 

i offer a program for the PR4. as far as P75 programs yes it depends as stephen stated there are some that work others do not.

 

thanks sgt. your answers are always appriciated.

Hyperducktuning, you're the one i've been looking for. Richie (teg92) told me about your chipped ecus. So you have a program for the PR4 right? What is it exactly? Can you give me more details?

thanks.

 

ERIKs program
Rev limit: 8500rpm
Dyno/Tests: Designed for bolt-ons and cams.

its Ericks racing program its rather for a mild setup. from few dynos on a b20b with Crower 404 (?) and many bolt ons it run rather lean. made only 8whp over stock

I prefer the P75 platform which I have 2 programs:
P75 : 92-95 Integra RS/LS/GS (B18A/B18B/B20B)
PYR program
Rev limit: 8500rpm
Dyno/Tests: Runs fairly rich designed for mild cams and bolt ons.

Skunk2 program
Rev limit: 8500rpm
Dyno/Tests: Race program for built up motor.

the skunk2 type program was tested back on the same setup above it made this time 12whp but not running so lean.

anyways I have complete P75 (that chipped - 2 programs) as well as shipping for $170US + hondatech discount 5% = $160US shipped.

 

thanks for the details. So you're saying that with a chipped pr4, my b20, crower 404's and my bolt ons i'd run a little bit lean? I'd rather go with a chipped p75, but is it gonna fit my 1992 Integra RS?

And i'm in Montreal btw, give me some canadian prices I would prefer sending you an ecu (pr4 or a p75) and then you chip it and send it back to me. Is that possible?
