That does sound very complicated. I'm really fond of the simplicity and accuracy of the p01/p59 PCMs, much much more than megasquirt and felt there was something not exactly right with the trigger coding or maybe in the trigger to spark coding. Not that I had access to the code, only from testing. I...

It doesn't work like that. The handling of the pattern is in the design of the code. The code is in the interrupt handler where it must be very fast and there is not time (or hardware such as spare timers) to implement some type of translation layer in front of the factory code, the factory code ne...

I want to run 58x on the older p01 or p59 ... Is this possible? The solution today is to wire in the Lingenfelter TR-002 box or physically change the crankshaft reluctor wheel and cam sprocket. Has anyone been able to find where the main crankshaft signal enters the program? If so why can't that wa...

INTERPOLATE_TABLE is the 3D lookup routine. A0 is the address of the table, D0 (word) value searched on the X axis, D1 (word) is the value searched on the Y axis. d2 is the size of the of X axis, and the result comes back in D0 as word. So in the above, 19 hex is 25 cells of the table in the X dire...

So... If it was 1a instead of 19 it would automatically jump to the first cell of the next row? In other words it reads the table as a single row essentially?
Or am I misunderstanding and it jumps 25 cells depending on the y axis lookup.

Has anyone been able to locate where the crankshaft signal is first processed in the PCM? I'd like to intercept the signal before it's processed
