Flex fuel tune ... Cranking
After my flex fuel install, the car starts just a little bit harder when it's cold. The timing table alcohol adder is all zero's. Rather than randomly trying numbers, I figured I'd ask. Is the cranking adder more than just a couple of degrees typically?

yes... from -40 to 90 degrees you need to add timing from 30-100% E content. 7 degrees -40/30%, 12 degrees -40/100%. 1 degree 90/30%, 6 degrees 90/100%. Populate everything in between linearly.

So I'm assuming the last 3 in each column repeat because you're never going to be over 85%. I wouldn't have done it that way but it makes sense now.
