I am looking into a b20 swap and I have to get an ecus... Which ecu would compliment the motor good and is easy in tuning... have to be good with emissions also??????????? help

 

Ok so I have to stay obd2 for emission and I was givin the recomendation of a p75 for non vtec (which it will be) and p72 for vtec... what are the ups and downs of the p75 and if I do get it would it be better to use it daily or get a obd1 and use the p75 for emissions only??????????

 

Just use a p75. The LS, and b20 are pretty much the same motor, except the displacement, so just use the p75, and up the fuel pressure a little, and it'll be fine.

Or, get a p75 and chip it with Uberdata or chrome, and then add fuel corrections that way, then you'd have launch control, and you could basically change whatever you want!

EDIT: you're going to have to make up your mind on what OBD you are going to run, you can't just plug in an OBD-2 ECU, and go get emissions tested, then change back to OBD-1 in the parking lot. You're going to have to stick with one or the other, unless you wanna change out distributors, and unplug an o2 sensor all the time, along with an ECU adapter.

 

thanks.... my thing is I live in NY and I dont know what the emmissions are like but I want something that wont give me trouble down the line... I have a vortech fmu so far and was thinking of getting a fuel rail and injectors next... how will the fmu come in handy?????????/

 

An FMU is used strictly for turbo only. It raises the fuel pressure per pound of boost it reads. This won't help you make any power unless you are boosting that ****.
