Actually if your seeing KR, its not a 1to1 ratio. I know my numbers are little off, but its more like for 1*of KR you loose~ 1.65-2.15* of timing.
The lowest timing advance I have seen is 8*, and that was an unmollested PCM with 14* of KR so that tells me that KR may fall on as a stair step.
Maybe you can scratch all this-this may only pertain the series 2

IIRC stock timing is set at 12*... That means if you have 0 KR at WOT you will have 12* of timing. You have to have a chip to add more timing. 20* seems really high for an 'universial' chip and seems kinda dangerous to me unless I had control over it. Also 3* of timing = about 1 lb. of boost.

Right now if i go at WOT my timing go down to 7, and the car "die" lost power,
cant find what is doing it, IAT is good, i have no KR at all.
under 7 the car tend to stall. but at idle its good.
(on choke, when the car is cold, the RPM bounce 500-1800.) when the car warm up, it go away.
Ive changed my crankshaft sensor but i need to do the case relearn, ill see after if this solve the problem.
Can a bad PCM do this too? the last scan we made, the O2 sensor test wasnt available.
and some other too.
