Turbo ECU L28ET

I have an 83 manual Turbo ECU. Will an automatic ECU work with a manual setup? 82-82 ECU should be the same, just not sure of the auto or manual trans.

You can use an Automatic ECU with a manual car, but not manual on a automatic.

I'm pretty sure the only difference is PRNDL switch might signal the ecu to idle up when the car is put into any gear other than P or N on an automatic car while the manual ecu might not have that functionality.

 

So you might not get idle up functionality as triggered by the shifter position but it may be possible the ecu will try to maintain target idle speed anyway.

 

It's possible that the pin on the ecu that receives the signal (pin 10) will do nothing but there is always the possibility that the pin has been repurposed for other functionality on a manual transmission car which might conflict with the signals sent by the automatic vehicle.......which is usually a ground sent to that terminal.....but not always.

 

Check pin 10 for continuity to ground with the ecu unplugged and key off to see if you get it when in any gear other than park or neutral.

 

If you can find them, check the 1983 manual transmission electrical diagram and compare it to the 1981 or early 82 diagram which is for automatic cars only.
