Does the kpro v4 do any auto scaling for afr when running e85 ...
For example, when setting closed loop, do I set for the e85 stoich or regular 98 pump fuel ?
I have flex fuel enabled with the continental flex fuel sensor and see on average 82% corn juice ..

so, now that's all worked out - using arduino code as following gives me the relevant info ..

unsigned otInt = (rxBuf[4] << 8) | rxBuf[5];
int otV = otInt/819.2;
int otAct = map(otV, 0, 5, 0, 200);

where rxBuf[x] is the canbus place for oil temp - mash them together, get 399 & divide by 819.2 then ...

Ahhhh


Thanks, that makes more sense - I was treating 1+143 but understand now they are individual values .... for my own sanity and others....

1 int = 1 hex
143 int = 8F hex
18F hex to int = 399 then / by 819.2 = 0.49
Then need to convert to psi (using the map function : ) map(value, fromLow ...

Hopefully this is the right sub forum to ask this - I emailed support over 2 weeks ago but no reply yet...

i'm looking for some help with the canbus output I am sending to a custom dash ...
