Stalling problem W/ cool coolant temperature

When I decelerate, pushing in the clutch & brake to stop, the RPM drops fast and sometimes kills the engine. This only happens when the coolant temperature is 60C-70C ish.. This Problem started when I installed the PFC. I wished the PFC to self learn and adjust fuel or something but it has been a year and no change. Any ideas?
Thanks
Rick

If you have the commander or datalogit you could try upping the water temp correction in the +50o range.
I had the same problem with it running lean during warmup, upping the water temp corrections fixed it.

OK,I have read the instructions for "water temp correction" but I am not sure how much fuel to add to the left or right #. What did you do? BTW I have the commander.
Thanks

Without a Wideband you can't know for sure if a rich or lean condition is causing your stall problem. If you want to play w/out a WB, make small changes (less than 5%) and see if your problem gets better or worse, if worse, try 5% the other way, if better try another couple % until it stops.

I will try the under 5% adjustments. Do I start with the heavy load, light load, or both?
Thanks

sorry to bring this thing back, but I'm having the same issues. How many degrees did you move it? I changed it from (I believe) 108-110 and 102-104

I can't help answer your question but I can suggest a couple of things that may help...

In Setting 4 'IGN vs WaterT Cool' change the retard at 60 Temp from 15 to 5.
Try new spark plugs.
