If I change the timing using the slotted holes method, will the timing advance in my evoscan logs change or is this a map lookup value and not actually measured?

In other words if the ECU is normally advancing the timing by 20* and I advance it 2* manually will evoscan report 20* or 22*?

I'm thinking the value will not change because I am turning the crankshaft position sensor to modify timing, and that's where the ECU get's the timing position from right? I can't think of another indicator for the timing advance but the lookup tables or the csps.

 

I think 22 is 22 and if you advance the sensor 2 degrees the ecu wil read the 2 degrees. If it doesnt it would make no sense advancing the sensor. My .02

 

I agree with you, Dan, since the slotting method is intended to trick the sensor. You'll advance the timing, but the ECU won't know about it, and therefore neither will EvoScan.

 

Evoscan and your ECU won't know it. Best to slot your holes, and use a timing light to see what the actual reading is and compare it to Evoscan.
Slotting the holes tricks the ECU by rotating the sensor a few degrees. The sonsor doesn't know any better, and neither will the ECU or any program that gets its information from the ECU. Only an external source (timing light) would know the difference.
