I'm helping a friend out with his 1st turbo project. 96 RS, built motor, Hahn Stage 2, MSnS v2.2. He has 550's, does anyone have a solid msq file that I can use as a base for this? What kind of Req fuel number is needed for the 550's? I haven't messed with tuning the Megasquirt forever and quite frankly forget what half the stuff does. I used an old file sent with the MS and got the car to run. Upping the REQ Fuel only made the car idle higher. Terry told me to mess around with the fuel bins which I plan to do next time I'm over helping him so that REQ Fuel number would be pretty helpful. Should I just use the calculator in the Megatune software? Sorry for the dumb questions, I've been out of the game for a while b/c my file works so well I haven't really be tweaking for some time. I'm still running 29q if that tells you anything. Thanks in advance. I'm going to read through the manual for the rest of the night but your expertise would sure be nice.
