MY advice usually starts out with "Do not listen to Mikey, he is wrong far more often than he is right" This thread is a perfect example. Any electronic device can fail.

You can lessen the chances of failure by mounting the Split Second ECU in an environment that is free of vibration and heat. In other words locate it inside the passenger cabin.

For the poster who said you cant tune without a wideband? How do you explain 80 years of tuning prior to Widebands being available? If you excuse is somewhere along the lines of all old cars being Carburated....Fuel injection has been around since 1953 if not before that.
