CME Limited at 20 Degrees of timing.

[Twistedshafts]

Hey everyone. I am working on my performance tune on the CME platform. I have seem to hit a timing limiter. I know in some of the old model ECM there was a limiter table, but not in this one. Any help on how to get around it? Would reducing the pilot timing in the internal flash allow for more main timing? Thanks for the help.

There's an actual limiter calibration that is set to 20 crank degrees.

I couldn't find this limiter like I could on my 07.5. Is there a table number it is under?

I wasn't aware of that, thanks for the tip. Sounds like we better add that in.

That would be awesome. Trying to keep my fueling in a 50/50 split and not possible with that limiter stopping me at 20 degrees.

GMPX do you know when the timing limiter table will be added. I have customers trucks to do but cant finish without this limiter removed.

What OS are you working with?

[Twistedshafts]

CME OS-32140602 and Cal ID. 32370231SB
It has an internal limiters of 20 degrees of timing.

Try this .calz, just save it into:
C:\Program Files (x86)\EFILive\V7.5\Calibrations\CME

The two new parameters are under the 'Main Timing' folder.

Cheers,

You ROCK! Thank you so much.
