I need help with figuring out which ecu to use with a LS/VTEC in a 92 Integra with an automatic tranny. I was told a p28 from a sohc vtec 92-95 Civic EX with an automatic tranny will work. Others say it will not work because it is a sohc and I have a dohc. I don't know what difference it will make as far as how many cams the engine has as far as the ecu is concerned but then again I am fairly new to the vtec power. Please help me if anybody can.

 

um i bet a b16a ecu from one that has an auto tranny. they are over in japan, but try searching for it because i am more then positive that should work. just my .02

 

Thanks! I am also thinking about using a reprogrammed pr4 ecu for the car as is(non-vtec) and use a MSD RPM Activation Switch to activate vtec. I could dial in what rpm is best with the rpm modules(pills). If finding an ecu for what I am doing is difficult to find, is this a possibility?
