i'm having drama with the stock ecu in my coupe, just wondering if the stock ecu out of a SR20DET will fit and work???? i noticed that the plugs that plug into the ecu itself are the same just wondering if anyone has used a SR ecu in a CA motor?

Just out of a guess, i'd say that the computers would be different and wouldnt work with each other...but ill find out 2morrow and let you know....?

No way. different sensors. Totally different ECU internals

Plenty of CA ECUs around. I practically gave my two away, pay no more than $100.

not interchangable at all. what are your issues?

I just moved back from QLD, and i had my cars brought back on a truck(TNT) and the funny thing is that when i put it on the truck it was working fine but when i recived it the other day it doesn't run.
On closer inspection i found that there was an earth(-) connected to a positive(+), which were there for my old stereo.
There is fuel getting to the motor, there is spark and i can even here the injectors pulse when the ignition is tuned on, but it just won't start and\or fire up

ANY IDEAS??????

check all the plugs in the loom are connected together..... do a cpu diagnostics test it is quite easy...
on the side of the ecu there is a pot resistor with a sticker over it. u need to twist the switch all the way clockwise. then turn it back after 4 seconds. it will now go into diagnostic mode.. the led will flash a sequence corresponding to ur problem..if it flashes 5 times fast then 5 times slow then that means all fine. all the rest of the codes u can find on the
nissan silvia website.. just go into the technical forums and do a search....

CAS plugged in?

I had a problem like this and the solution was simple i had given the ECU an accessory wire as it's ignition wire, so when i turned the key to on everything would like perfect but go to crank it the engine would just keep turning over but with no combustion as when you crank all accessory wires get turned off so it was turning off my ECU, it prbably ain't your problem but I'd just have a double check of your wiring.

Hey you tried getting the coil pack tested? My mates crx had the same thing but the coil only had enough go to spark with the plug out of the head.
