Looking through the outpc variables in firmware 1.3.0, I see a variable named "ext_advance" at offset 454.
I was really hoping that I could put any ignition offset I wanted in that variable, to arbitrarily alter the engine's timing through CAN, however the final timing advance didn't change and on top of that, my value was getting overwritten anyway. Searching the forums doesn't yield any results - just that it was originally named ext_retard, and no results on that either.
So, what does ext_advance do and how could I manipulate the timing like I thought I could?
Thanks!

Re: External advance?
ext_advance is an outpc output of any external advance adjustment. The input is sent to datax1.SpkAdj and usually comes from a trans controller.
From ms3.h:
Hopefully that should get you going.

Code: Select all
int FuelAdj, SpkAdj, IdleAdj, SprAdj; // allow other devices to change our behaviour. Published offsets of 512+118 = 630 et seq. AVOID MOVING

Re: External advance?
Any chance the code ignores negative values on timing? 40 adds 4.0 degrees, -40 does nothing (ext_advance is 0 degrees instead of -4.0).
