TOTAL TIMING ON A P75 ECU ???
If anyone knows the exact amount of total timing advance of a stock p75 ecu that would be very helpful to me at this point of my "creative tuning" setup... 
I have an idea that it somewhere between 27-30 deg at full advance, but I want to be 100% sure... thanks!!!

on a p75 which is an OBD1 LS ECU at o vaccum and highest revs you are at 27.75. Why do you want to know? Are you advancing timing? I've done 2-3 degrees with good octane and noticed only mild results on an NA app. GL

No, I am pulling timing (mechanically) with a btm and I will be pushing the stock engines limits with some old school technology, so I wanted to be as accurate as possible from my start point.....Thanks for the confirmation though...

.
So it looks like my estimation was fairly close...So basically if your base is set at 16 deg btdc, your looking at 27-28 deg total...correct???
