Custom PID's for different fuels I.E E10 & E85

[WHYTRYZ06]

Andy,

Based on the LC-1 being programmed for gas being 14.7, here's what I come up with:

GAS (stoich 14.63): {EXT.AD1} * 1.990 + 9.952
E10 (stoich 14.12): {EXT.AD1} * 1.921 + 9.605
E85 (stoich 9.78): {EXT.AD1} * 1.331 + 6.653

So for example, if the LC-1 was reporting 2.35V those equations would give:
gas AFR = 14.629
E10 AFR = 14.119
E85 AFR = 9.781

close enough joe

so i set the lc1 to 14.7 factory setting and use either pid u listed depending on what fuel i use?

joe what about if i wanna program the lc1 to read 14.12afr, can u redo the pids w/ the lc1 programed to 14.12?

Yes, that is correct.

[WHYTRYZ06]

Yes, that is correct.

nevermind my last comment, ill just leave it at 14.7, what u think or go to 14.12?

if i leave the setting at 14.7 should i change my calc.pid file to these new pids?

i want ur opinion....

If you leave the LC-1 at 14.7 then your gauge reads the correct AFR for the fuels you mentioned, is that what you see...?

If you leave the LC-1 at 14.7 then just use the calc pid for the fuel you're using... this is simpler than reprogramming the LC-1 every time.
