M142 fuel table help

Postby itsme71190 on Sun Nov 17, 2024 10:33 am

Good morning,
So my tuner seems to be extremely busy and we can't find a good time for him to remote in and adjust cold start fuel. I moved from a very hot environment to somewhere where it's been under 20 degrees and it takes about 15 starts for car to kick over. Can someone walk me through m1 to adjust these tables by about 15%

Hi,

have a look at the Engine Crank Fuel Volume Compensation table. You can modify the values by a percentage. This is done by highlighting the cell/s needed, and then, for example, typing 1.2*. This will apply a 20% trim to the highlighted cells.

Thank you for the help! Need assistance on one more thing if you could....
E85 levels. I'm using a blend of e85 to reach around e50, so it is an alternative fuel. But I can not find the current level I have in the fuel tank. I have a sensor wired in.

Hi,

The M1 Flex Fuel User Guide will provide the information that you need to configure a Flex Fuel sensor into your M1.

Maybe you are looking for flow rate, but the Ethanol Sensor provides "Fuel Composition", ie, 50% for E50, 85% for E85.

The M1 will calculate a Fuel Flow based off of the injector PW and injector calibration.
