Hi

When i ground the MAT +, then the TecGT goes in to aux rev limiter mode.
When the rev limiter is reached it will first retard -12degrees, then half current to coils, then full cut.

Question is, does the TecGT just take out 12degrees from the ignition table? or does it run the ignition to actual -12degrees?
And what happends if i set the default value to -30C, and then put in -10degrees at the MAT ignition table? will the total actual ignition then be -22 degrees? or does the aux rev limiter override the MAT ignition compensation ?

Thanks
Asim

The -12 of the revlimiter will override all ignition trims and it will go to 12 degrees ATDC.

ok, so it will not help anything to set the default value to -30C, and then go to MAT ignition table and enter -10degrees then?

Any idea to how i can set up a launch control on my car with some of the extra in / out channels?

Thanks
