Hey guys, Im creating maps for my car for the Megasquirt. Its a Twin Turbo'd 3.0 Liter. It will be running speed density with a nice front mount...and maybe a little methanol to keep it extra cool.
You can see the tables here

You can post back here and ill heed your advice. Thanks guys!
Not knowing a lot about that motor, the amount timing seems aggressive (not enough retard) as a starting point. What's the compression, fuel, turbo, bore size and chamber/valve arrangement? AFR table looks good, too rich if anything. I usually run 12.8afr or so up to 120kpa and then richen from there, it helps spool. I usually don't run richer then 11.8:1 on a car that uses good fuel. Higher octane, I'll run it leaner by a bit.

Well thanks for the reply. Its a Mitsubishi 6G72, if youre familiar. If not.....
8:1 Compression Ratio; 93 Octane; Stock 9B turbos (TINY!); 91mm bore; V6 with 24 Valves;
I may lean it out once I get it running and stable. I think keeping the cylinders cool with the extra fuel may be a good choice but if my EGTs are in check ill lean it out.
Watch the IAT's, the bigger the rise with boost, the richer I'd run it.
