stock ingition map
 
I was wondering if anyone knows what the stock iginition map looks like in the 1.6l ecu

thanks
now to look around the site for spark maps on turbo motors

no wonder it felt quick must of been 36 degrees of timing with the t3 up top, goodness

this is safe to start:

bringing this backup anyone know what 0-15 on that chart references too?
I would understand what 0-5 would mean in there but not 0-15, guessing some metric measuring of airflow.

Came across this looking for the same information. Might be psi. Atmospheric pressure at sealevel is 14.7psi so you're unlikely to have readings higher than 15.

My guess would be manifold vacuum in PSIG. So, 0 would be WOT.

That'd be a neat trick considering the OEM ECU has no pressure sensor to detect manifold pressure/vacuum.

The numbers are likely arbritary and rather meaningless unless you have the OEM curve for the MAF/AFM.

And 15 will be WOT not 0...

Yep. Fingers racing ahead of brain again.
