I'm trying to settle this between a friend and myself...He says you use a P30 and I said you can't and that it need to be a PR3. Who's right?

 

P28.

 

p28-obd1


I thought 91 tegs were obd0

 

u can use either the PR3 or the P30, they are both non OBD

 

really, I thought p30 was obd1 from the del sol

 

I dunno, do a search and find out...now I am confused

 

Well i do know you gotta use an OBD0 and for sure the PR3 and PWO are.

 

best choices would be :
PR3 and PW0 as they work with nonobd electronics and plugs and have DOHC VTEC capable maps and sensors.

PR3 can said its a slightly better choice as more ECU programs are offered for the ecu (such as no knock sensor or 2nd 02 disabled)

other choice is to use chipped PR4 ecu (rs/ls/gs 90-1) + vtec controller

 

Thanks everyone for your help.

 

I'm using a PR3, works just fine. Throws a code for the knock sensor though.

 

I have a 94 Sol, and the stock ECU is a P28, which was with the B16, I did the LS/VTEC bottom end swap, and the P28 works great, but if you really want results the best combo I have seen is the Mugen spec ECU... my 2 cents
