E40 Flex fuel spark table will not accept negative numbers Now there is a way to get the negative spark numbers thanks to James at ShorTuning in KY.
Those of you that are wanting to still have negative numbers for flex part throttle on the E40 can get around it this way.
Use the 12635 Alcohol PE/COT to add a negative number. I usually use a number like -10 in the entire table.
Now you will want to counteract that by putting a +10 in the 12678 Flex Adder table. Now you are back to zero but it physically shows +10 in the table so anything below 10 is a negative value.
At this point now you can populate flex tables like you would on any other platform, just realize the values will "appear" to have 10deg more timing in them than is actually there.
