sr and ca ecu's

[sydwayz]

is the ca ecu basically the same as an sr ecu? and is the wiing going into the ecu basically the same?

[sydwayz]

what im trying to say is how do i make my ca18det run on an sr20det computer

Dude its not going to happen, just buy the proper ECU or go stand alone. Some guys on here can point you to stand alone for less then a grand.

It could happen. If you managed to get it all wired right then you could get a custom chip for all the CA parameters.

Worth it? No.

It's been done. Lots of work to get it to work right. IDK if the CAS signals are the same. That would be the major caveat.

I can't see much in the lines of an advantage....

[sydwayz]

the reason im asking is that my piggy back SYSTEMS 1,2,3, and 4 are now getting hard to tune together and now its to the point of spending money for a stand alone and i think i wanna go with the apexi power fc d-jetro for the 93-96 sr20det because the ecu pinouts look to be the same. can anyone point me in the direction for the wiring that might need to be done. i know its been done on yellow munsons car.

agreed

I think there a thread maybe a year or so ago about doing so..... never heard the out come. I know some use the SR Power FC as they are "easier to find"

I would run mega squirt instead. 150 bucks and some wiring and a trip to the JY. cant go wrong

[articzap]

Or Nistune with stock CA ECU?

Yellow Munson will send you a plug and play harness for the power fc for 350 or 375$.
