Tuscan ECU burned out.

[so called]

Hi All,
just wanted ask a quick question regarding my knackered ECU.
Had a problem driving home from Spain where my Tuscan developed a servere missfire. Turns out to be the ECU (thought I can smell burning electrics !).
Anyway, before we conne t a new one, I just wanted to ask opinions on what may have caused an overload ?
My Mk2 Tuscan is de-catted with powertech cans.

From my simplistic veiw, I wouldnt expect an ECU to be effected by any system or sensor feedback.

Thanks for any advise,
Tony.

Offering a very simplistic opinion - and I'm no expert, but could it be a poor earth?

I would have thought that a duff sensor would not cause the ecu to fry. Might have other effects, but a sensor going open circuit wouldn't damage the ecu - all IMHO

High supply voltage? Possibly can be caused by faulty alternator/regulator.

Especially on a nice long run.

Hi, thanks for your comments.
Definitely need to have things check out before hand.

Just to update, Had a replacement ECU fitted and the car is running great.
It actually seems better than before so mybe the original had some kind of fault or the Chip wasnt quite right ?
Anyway,in doing the repair, Ian at TorqueRVT fitted a suppressor to the alternator.
This has cured the wonderful little dash lights problem where I would have to press the brake peddle after turning of the engine to get the dash lights to shut down.
TVR at its best
