There is a Load (KPA) vs Temp table, yes.

Must've not paid good attention. No such thing in OBDI lt1_edit, even in the latest release 2.2.

im surprised to see that its not available when the PCM does increase timing when cooler temps are seen... or am i wrong... Even if you lower the IAT 14C the engine temps go down 5-6C which is not enough to go to the other lower spot in temp although it interpolates. But I have the ECT in the 80-92 range 0 out which is where my engine is most of the time and I see an increase in timing from night to day.

Yeah it would be interesting to see because I still can't figure out if the WOT timing I'm seeing in DATAMASTER at say 5k rpm being 36* is the actual timing or if its really the 33* of timing I have set in my ignition table. Because I dont have a keyed hub with a mark to figure out with timing gun or the IAT table which might be the result of the extra 3* added showing in datamaster I just dont' know
