It would be the opposite actually. Less E85 would mean lower trims. I think I figured it out... you don't have an intercooler do you? What was the IAT at the end of that log?

I could see 40% and stock intercooler doing 17.5 psi and not having large trims up top since the IAT would be so hot that the density would be down. Or maybe you have a miracle car?

Why couldn't timing recover like THIS in 4th gear? Went back to the drawing board in ATR for some tweaks and look at the result. Sigh, wasted trip to the drag strip. Best run was as 12.15@122.27 @ 19 psi.

This log is at even higher boost and it hit timing like a champ.

Good theory - stock intercooler (for now). IAT was 118 at the end!

If you do not see it then update your "user interface" version.

If you are not getting low fuel pressure codes.... leave the auto learn function ON..... 40 is as low as auto learning will take it and 40 is best for your current amount of mix.

Means you need to flash the ECU to get more fuel in. A little bit over is livable, it just means you are running leaner than target at those points.

OK.thought so.I get spikes hitting just over 50.could flashing be a bandaid if hitting over 50?example,what if one with same setup is under 50 trim but then another with same setup is hitting over 50.say like 55-60 trim.is flashing the right answer or could there be another way of figuring out why its hitting over 50?just curious.

If you are just a little over 50 I wouldn't worry about it. Its not going to explode. That is the limit that the ECU can add more fuel based upon what it thinks the engine is doing. 50% more than it thinks is normal is a lot.

Read the code, and then if you are unable to figure it out search or post in the support section.

The dme does not like to run with fuel trims maxed out for too long of a time.
A spike is Ok.... running several seconds at 50 (the limit) will be flagged as something wrong by the ECU. What is your "Fuel Open Loop Mapping" value?
Do you have it set for auto learning?

Oh yeah, you trimmed out probably. Pull the code... You need to tweak your open loop, lower your E85 mix, or stack the flash. To be honest though at 40% mix you get 95% of the performance of a 50% mix without the chance of SES issue.

Yes, and should be located on post #1 along with everything else.
How can I use the jb4 to its fullest potential and take advantage of all of its features if I don't know which menu does what.

Little confused...when I installed the G5, I uploaded the G5 firmware not the latest G4...was I suppose to do both?

No, upload just the latest G5 firmware if you have a G5.

Also download the latest interface (9/1), and make sure to select G5 in the drop down menu, under the settings tab in the interface.

My car with cold weather is hating E85! Every car is different i guess.
I added 2-3 gallons of E85, then filled the whole tank up with 93 octane. so thats a pretty low mix.

Did a log about 20 miles later, and my boost seems to be capping at 15psi, and my trims are over 50..

FBO about 60*F out. 2-3 gallons of E85 to a full tank of 93 octane.
This was with auto loop on, not manually set and at a default setting of 80. At the end of the run it was at 90
