so its ONLY the opening time and not both combined? that might explain alot... so, with the opening time of 1.4 (instead of .7-1.0) there would be an additional .4-.7 ms of fuel, which, even with a VE of 1, would still give fuel to run the car... that sound about right?
cant find where i found the opening time, must have misplaced the .pdf
Culprit found finally - cracked coil

of course if you set your req fuel value too high then you will be able to idle at a ve of 1 as well. I think many people set their req_fuel values too high because they want to have more hp then they really have, so the equation spits out too high a number.
Try halving your req_fuel, reset the opening time to the default (1.0), and try tuning it again.

wierd running
ok, changed the opening time and it seemed to help, BUT it was still running rich, and i could only semi-keep it running by holding the threttle open, and even then it would surge. it would rev up some, almost die, rev again etc. i have a datalog and .msq and tables.

did some more work on it today, upped the req_fuel and VE table, but she still will only start and die after a little bit. Still runs very rough. was able to keep her running for a bit around 4000rpms, but started to smell something hot. looked outside the car and the muffler was radiating a ton of heat, and was cherry-red inside. i think that might be the excess fuel burning off from the stuck injectors but *shrug*
also, im wondering if setting Multi-spark on might have killed one of the GM coils i have as it seems like 2 cylinders arn't firing. when i swapped plugs earlier, 4 were fouled, 2 were mostly clean (paired cylinders i believe) ill see if i can get spark off of all plugs (injectors off) and see if one isnt sparking. Can a coil just die suddenly like that? that might explain the rough running and poor starting etc..
too bad i only have a day or two left before going back to school.....

well, swapped the coils and found that the 1-4 coil was cracked. got in and she fired right up with the new coils and ran fairly well. too bad i didnt see that earlier. added some stabil to the tank and ran her for a bit to get the sabilized fuel into the lines and injectors. at least i know she works fine for spring break
