right now i'm running my ITR powered eg hatch with stock p06ECU chipped. Couple ppl sat in my car and they said the vtec engagement is not as aggressive an ITR motor suppose to be and i was puzzled. So i sat in their ITR powered coupe and i admit their vtec engagement is louder and it pulled harder than mine. I asked him why is it like this and he said he used the original p73 ECU (JDM ITR) with obd2b-->obd1 harness.....i have the p73 ECU at home too and i'm wondering do i really get better results with p73?...




cliff notes: should i use p73ECU (JDM ITR) instead of a chipped p06 ECU

P06 is the 92-95 Civic ECU right? Ya I would suggest you use P73 if you have it Peter. Conversion harness isn't that expensive either.

yes it is the eg ecu....but wouldn't it be better for tuning later on....

if your going to use crome for tuning u will likely have to go back to your p06 civic ecu. and i would confirm wityh whoever chipped your ecu that it is infact a itr program in the chip.

Is that P73 an OBD1 ECU?

imported_360_vortex

noo...it's obd2b

Nova_Dust

Stupid me haha

So that means your car will be OBD2 then?

Get your car dyno tuned, maybe that will help?

i can burn you a new chip with a stock ITR program. A chipped ecu is just as good as a stock one, provided you have the proper program on the chip.
I've been using a chipped p28 in my b16 powered eg coupe now for like 2 years with no problems.
What rpm is your vtec crossover set at? Maybe you need a tune up. Do you have an intake/header/exhaust? Did your friends? B/c i/h/e makes vtec way louder and pull a little better.
