Is anyone using the GM Performance Parts transmission controller (12497316), which I think is the same as the FuelAirSpark.com controller?

I've just ordered one and would like to compare notes with someone who's integrated it into their stock harness so that the speedometer still works, etc. I'm also curious to see if the codes that the PCM will set when it realizes it can't control the transmission will interfere with ASR or ABS at all.

Thanks!
