A Mines ecu is not something magic. It is an ecu with a chip that has been made to suit a particular car. If you happen to have a car that is set up in exactly the same way it will work for you and it will still work if it is pretty close but that would be a fluke.

The chipped ecu from EFI is virtually the same as the Mines ecu with the important difference that the chip has been made for your car after tuning on the dyno.

It would be very unlikely that a chip made for an RB20DET would suit your car. There is a Mines ecu on tradeMe from a 260RS. That is not going to suit you either.

Go to EFI and see if they can make a chip to suit your Mines ecu. If they can your money will not have been completely wasted.

Good luck.

ok guys i have the mines ecu in the car now. these are the problems..

idles at 1500 rpm and bounces around a bit.

stalls every time i come to a stop.

doesnt boost at all until around 4 to 4500 rpm, but shows its running 12psi from about 3000rpm.

splutters around heaps and doesnt feel good at all.

any reasons for this?

the guy said it came off a rb20det engine so would that make a difference?

If it came off rb20, of course it will make a difference. ECU is not made nor tuned for your car!

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
