Not completely sure yet, will find out tomorrow..

But I do believe my ECU took a sh!t..

this is on my 87 GL-10 TurboWagon.

When I replace it, will I be able to replace it with one from an 88-89 turbo? should it be GL-10 only?

or is this going to end up like the intake manifold.?. wiring only fit an 87 TWagon

If the numbers on the replacement are the same, you should not have any problems.

I don't think the '87 GL-10 had MPFI like the '88 did if I remember right. Having the turbo makes a difference also I believe. It may work with a '86 turbo. Comparing the numbers will keep you straight.

Have you checked for voltage getting to the ECU before you say it's bad?

All of the turbos are MPFI the big differences are that 85-86 and maybe 87 had the vane airflow meter and inductive pickup type distributor; where the later ones had the hotwire airflow meter and had the crank angle type distributor.

Thanks for the good info GLC. I thought MPFI came out in '88 and was not aware it was already out for a few years. Good to know about the changes also.
