Alright, tonight, during the chat on AIM, dropzone was tellin me I should do a P28 conversion. I was about to ask him more about it, but AIM kicked me and I wasn't able to finish talking to him. I was wondering what is the P28?

and also, where could i get a OBD1 wire harness? any more info will be useful

The p28 is the 92-95 Si/EX ECU, which is OBD1 and its probably the best ecu because it has the most programs and is the most versatile (spelling?) and you can get a harness from this guy on Honda-Tech, just browse the EF forum, its all over the place......

the P28 was the z6 stock ecu
you will need that and its matching distributor
and a conversion harness ($150)
allyou have to do is re pin the distributor plug and
wire in a 4 wire O2 sensor along w vtec wires
POOF
there you have a P28 powered Z6

incase you dont believe that it works
i run a HONDATA P28 stage 4b in my 91 zc turbo hatch

alright, whats with this dizzy business? the z6 came with the dizzy still in it, shouldn't they all come with it?

alright, is there anywhere on the ecu itself where it says which it is, just to make sure it is the P28. Thanks for the help everyone.

He is just saying that whichever ECU you are using, you must use the corresponding distributor.

Look on the side of the ECU and there will be a string of numbers and it will say P28 in the middle.

Thanks for telling me where to look for the number, because I need to go back and complain to those bastards. its a P06 ECU, just noticed that they just marked over the 5 in 1.5l and put a 6 so it says 1.6l. sorry bastards, gonna go back and tell him to give me the right damn ecu.
