Hi just wondering how can I adjust my map to turn the car on cold start. It’s 30 degrees here in New York and my si is a built motor. K24a2 block 12.5 bc rods supertech springs and retainers and valves skunk2 ultra 4 cams. Full ported Xsseive side feed ktuned 72mm 4” cai id 1000cc injectors. Walbro 255 on e85.

Have you discussed this with your tuner?

You may have to reduce the amount of ethanol in cold weather.

I tried calling my tuner but no answer. How can I reduce the amount of ethanol?

put less ethanol in the tank

Look at the Calibration -> Ethanol -> Ethanol ECT cranking table and either post the calibration or tell us what is in it.

i think i figured it out. in the cranking fuel trim table, the 1st column from 0 rpm - 2000 rpm i raised it by 15% and the car started.
