Rich after Flash

[jsllc]

After hours of logging this will create a good starting point. My E67 (2012 ZL1) wants to run from 112 to 140F on injector temp.

To create usable values I take and subtract the value in the 140F column from every thing above it and then take the same cells and multiply by .7. Everything 140 and below I Zero out.

This will cause some extra fueling to happen during warm up but the MAF cal and SD will be correct for normal operating temps. I filter all air calcs so they only log 110 to 145F on injector temp and then I do not have to worry about my data on Rich-After-Flash. I have some formulas that give actual pulse width numbers to plug into cells but they are not yet 100% reliable. The above seems to be SAFE (no new lean conditions) and alleviate 90% of the rich after flash issue.

I agree!

now a 1516 fix and rich after flash fix.. All very nice additions.

What 1516 fix are you talking about?

I tracked the data and mapped Injector Tip Temp vs FTrims. After about 130F trims would go up. Tested it all the way to 200F. It became easy to see it had to be in table because the fuel amount went up with temp on the injectors. All other values stayed close to the same or in other cases went up and down. The only one that change with the fuel value was injector tip temp. Sent that data in a table form to HPT with fuel variance by temp. They took that data and found the table and published it for a couple of test ECMs. Good news is we can stop wasting time.

Do you have the config set up to log this?
