Re: engine de-rate while shifting

Not sure if this is the place for it >> http://www.msefi.com/viewtopic.php?f=78&t=34667

Just a thought about triggering the knock sensor retard during a shift. It might be useful if any standalone controller pulls pin xxx high during shift. :?:

Re: engine de-rate while shifting

I think he's trying to avoid shifts at full engine power, something i've wondered about as well. Could it be as simple as a 1 second window during up/down shift where the MS2 pulls say ... 4* timing? (or some user configurable value)

Re: Ford Auto trans details

A few more docs, i'm not sure what you guys mean by the pullup. I interpret [199 LB/Y] as +5v vref, apply that voltage along different points in the stacked resistor voltage divider to produce a 0-5v signal in [359 GY/R], this then makes it way back to the PCM as sig rtn. I might be overlooking some...
