I suspect that Bosch tried to use something less expensive (like triacs, board substrate, or soldering method) in the LH 2.4 ECUs for '89. Maybe that of there was a bug in the programming. IIRC it was the '89 non-turbos that had the really bad track record.
Nobody has ever really said exactly why the '89 ECUs have such a bad record. I'd love to know (having an '89 SPG.)
I haven't seen the pinouts on all of the LH 2.4 ECUs for Turbo and Non-turbo, but I think that at least '90 and Up for each type are nearly identical. There is a difference between the '88 and '89 ECUs for the non-turbos that causes the A/C compressor to not work if an '88 ECU is used in an '89.
Ubipa is working on a site with lots of info on the LH ECUs. Look over on the performance board for posts by him in the last couple of days.
