Re: [DML] Serious Megasquirt Question

Do you carry a spare carb around in case the jets get clogged?  What about if the throttle shaft locks up? what if the accel diaphram breaks and the carb leaks all over the place? what is your backup plan?

Can it happen... Yes.  Is it likely enough to warrant carrying around an extra ecu... Not even close

Once you are done tuning and messing with the install (assuming you don't do something like zip tieing a harness to the exhaust manifold) it is just as reliable as any other ecu.

If it makes you feel better you can carry a butuane soldering iron, the schmatics, some components, and a meter.  I never did.

I mean controller replacement. My little brother had to replace the onboard computer in his Oldsmobile not too long ago. For some reason the thing died while he was at work. 

Onboard electronics do die. I helped a DeLorean owner last year whose Bosch ignition module had died (his dead ECU donated the harness connector for the adapter my Duraspark module is using).

All electronic devices are subject to failure. It is unrealistically optimistic to claim that one's own devices will never fail. If I was totally dependent upon an onboard controller for my fuel delivery, I would definitely have a contingency plan.
