MAT used to modify timing advance?

Is the MS-II set up to do this? I've not found the settings for it anywhere, just coolant based. My timing map on the truck is really close, so close in fact that as the ambient temp goes up I sometimes get a rattle, particularly pulling a boat up one particular hill. Doesn't do it in the morning, and of course doesn't do it before the engine temp has been up long enough to thoroughly warm up the engine compartment.

I guess the smart thing to do would be to build a cool air induction system for it but that's going to be complicated. If I could just retard the spark something like 1 degree for 10 degrees that the MAT increases I think that'd handle it. Is there any provision for this? Thanks

What you want is in MS-II v2.68x code which is currently near the end of beta testing and will be released as soon as a bug in the wheel decoding is fixed and tested. You could actually try it now by downloading from the beta list since I don't think you use wheel decoding. It provides a table of 6 or 10 points of MAT vs Spark retard.

Thanks Al, just what I was hoping for. I'll try to download and flash it this week sometime.
