ecu????

[WtbRHD]

k im dropping in a f23 into my 90 cb7, and i need to kno wat kind of ecu i will be needing in order for vtec to work? I've heard that any ecu from 94 and up would work, but im trying to keep it obd I. so i'm thinking that a 94-97 could work, but not sure if yall can help me out It'll be nice thanx

i'm using a P28 ECU from a civic SI to run my vtec for my F20B.

p28 is supposed to be the best for chipping cuz you have more options as far as what you can change. that statement about any 94-97 accord, nope those accords did not come with a f23. you are thinking of the f22 v-tec. i would get a stock ecu for a f23 vtec. 6th generation accord i think?

a buddy of mine has a p05 or a p07 not sure which one, he ask me if i can use that one i said dont kno. so will it work??? (it's vtec out of an eg hatch)

[Cb7GHOST]

no because I'm pretty sure F23's are OBD2. are you talking about F23AX, out of 98-2000 accord?

[WtbRHD]

f23a1 to be exact so yeah, and cant i just get a obd2 to obd1 harness? just asking

unless you plan on tuning, stick to the stock ecu that goes with the motor. Buying a p28 and not tuning is a waste.

Yes you can use an OBD1 P06. These ECUs have to be chipped with an(EPROM) and the VTEC chip-set. The P07 is a VTEC ECU so it will just need the EPROM chip. You are obviously going to need the OBD2 to OBD1 harness. I'm not 100% on the P07 Chipping. I've never done one myself.

The P06 is the most common and easy to come by, cheaper as well. I have soldered up a number of P06 to P28 ECU conversions. They work just fine with a good base map and proper tune.

As stated above Chipped ECU is a waste without tune
