Just a thought? Does the car have an electronic shift kit?

If it does, then the resistor values, which will be fine for the EB ECU will be wrong for the EL ECU and will result in very hard up and down shifts.

nice logic, but nope, it doesnt.

do the 91LE and 93LE solenoids have different resistances?

There are logic differences in the ECUs, requiring different resistor values in the Shift Kit depending on if you use an EB or EL ECU. The boxes are the same electronically.

eb dont have a tcm do they

i just thought then that maby the el shift paterns are matched to the el diff ratio but this eb might have a different diff ratio to the el that this computer came out of.

because if this eb has a different diff ratio to the el this computer came out of the shift paterns are gunna be way out of wack



while where on topic about the el ecu and thermo thing
i thought i might ask yas, with my ea ive fited the el auto ecu in my car thats manual but ive done the resistor mod thing, but if i try and run my thermos off the el ecu will the thermo fan operation
be all over the place.
thankyou


good luck with the eb jason

and by the way how much you after for a j3 chip with a el xr6 manual file on it.

All the symptoms you describe were apparent in my XG when the S5 solenoid was dead in the auto, even the erratic downshifts, aswell as missed gears. Perhaps pin 38 (s5 output) in your EL ECU is damaged?? Check for corosions of the pin or slip the case off and check the solder inside the case for evidence of moisture, ECU may have been wet at some point from a leaking windscreen or heaterbox.

mmm. If its the ECU, it will be the second EL ECU i've had problems with in this car. I need to find another EL to test it in, or another EL ECU to try in the EB...

where abouts in vic are you? i may be able to help.
I've got plenty of ECUs

el ecu in my nc2 fairlane worked great, basicly ed should work with a eb2 same box, has this only played up since the ecu changes ,maybe a pin prob at the conector or selector /inhibitor switch prob the only codes sholud be for the fans and the bbm , i put in the soliniod for the bbm under dash just to keep the ecu happy and had all the fan wiring etc from a el, no more codes

OK, another update...

Tried another ECU (thanks DJ_Brown), same problems. It seems to misbehave mostly when cold, but sometimes when warm too. Sometimes it behaves perfectly. I doubt its wiring related as the car behaves perfectly on the EB ECU.

I put a multimeter on the S5 solenoid line when it was playing up and the pattern seemed the same as with the EB ECU. It drops to around 10v iirc just before shifting.

Any other ideas? It throws no trans related fault codes either.

Anyone have any ideas on this? The car runs so much better with the EL ECU -- apart from the shifts which feel like the engines about to fly out...

I have just swapped over to a new coil and the harsh shifts seem to have gone, I wonder if its the ecu playing silly buggers over an old coil.

Hey guys,

Giving this another bump. Still not resolved, and would like to get to the bottom of it.

Im planning on putting a DMM on each solenoid and watching the pattern with EB then EL ECU. So far I have done S5 and they were identical. Anyone got any other ideas?
