Looks like the recent crop of engine problems is fully on Ford's radar.
Can you name names of 'tooners' using these files, or would that be inappropriate for a public forum?I'd attribute these failures from the majority of "tooners" that blindly load in tuning company provided canned tunes, and not understanding what is being changed. The 5 degree global spark adder is BAD. Why a tuning company released a file like this to dealers makes no sense.
For those that do not know, the global spark adder is a parameter that takes the calculated spark, and then adds a certain amount of timing to it. This comes in after the knock sensor calibration. If the car is knocking, the PCM removes timing, but then the global gets added back.
I've never used a global spark adder for anything other than quickly finding what a combo likes while on the dyno.
Ken, we have a local gas station that sells leaded 110 octane race gas for around $7 a gallon.
