wich ecu to go with for ls/vtec

[ls/vtechatch91]

i have a 91 hatchback and im staying obd-0 so i was wondering wich ecu i can go with??????? can i use the 91 integra ecu (pr4) and just use my v-tec on a toggle switch??.. or do i have to use the pr3 ecu? i also heard the the pr4 ecu's dont fit into the harness... so if i could get some info on this it would be great thanks

what ever you go with, id chip it with the MINIMUM of a stock GSR map, but id really RECOMMEND you have a custom map made for your engine. Tuning is one of the biggest reasons people label the LSV as "unreliable".

I would convert to OBD1 use a P28 with GSR maps... wait thast what i did do...

there are only 2 VTEC obd0 ecus. PR3 and a PW0. I think only the PR3 can be chipped with turboedit... something about eproms or i dont know.

good luck.

convert to OBD1 its easy.
