What year is your friends car ?
I'm thinking this ecu is maybe for the earlier 185 model 89-91

When I first got this ECU I put it in my car and the car wouldn't start it would turn over but not fire so I took it out and tryed it in Friends car and first turn of the key it fired up and ran fine so I thought I would give it anouther go in mine, and same thing happend again it would turn over but no fire I have checked for error codes and it shows number 12 RPM signal fault - No G1,G2 or NE signal to ECU. I have checked all the wires they seem fine and my standard ECU works perfect showing no error codes has one got any ideas what I could be? The ECU is a E.L prototype Wich removes fuel cut, 112 speed limit and rev limiter And has a different map on it. My car is a ST185 JDM 1992 |

There are a number of different pinouts on the various gen2 3sgte ecu's. One variant has the dizzy signals in a different place, this just happens to be the verion in my 1990JDM. The following has some useful information about the standard ECU. http://www.cdd.co.uk/stuff/standard_ECU.pdf You can work out which pinout by checking the wire colours in the loom against position in the plugs. |

It is most likely that it could be that the ECU is for the wrong year/pinout config as has been suggested or.... IIRC the standard ECU will still run and not show a fault code with quite major issues with camshaft sensor inputs. I have had this once where an Apexi Power Fc would not a run a ST205 and yet standard ECU would. After lots of time and head banging it became apparent that the cam sensor was only outputting a single signal not all three of G1,G2 or NE. |
