How to fry an ecu?

I just wanted to make sure that there is no COMMON problem with this engine/ecu (like trunk lid leak is common to Supra, because of dried rubber gaskets).

Well...after reading all these supra forums (like 4-6 on the net), for the last 3 years, and all the old threads (like 3-4 years back), I can say that the ECU does not appear to be a regular 'problem' (like BHG, radiators, turbo oil leaks).
It seems that neither are the TPS, ISC, cold start system, temp senders, oil pressure senders, water pumps, alternators, power steering pumps, wheel bearings (seem to be very tough), and ABS system.

I think that most electrical problems are caused by (1) eventual component failure, and (2) by someone working on the car that was not very proficient with Supras (human error with assembly/disassembly).

You gotta figure, these cars have probably had 3-4 owners, and several repairs before you got it.

hey its impossible to fry the ecu of a supra. mine shorted injector wires to the manifold and it still works after the short was taken away. ages and ages spent fault finding just to find that there was a massive short circuit every time i tried to fault find. those ecus are electronic tanks.
