I have not tried using another ecu just yet, I figured I would ask you guys first. I've attached another datalog where the same issue occurs, but this time I got the P0130 O2 sensor check engine light. Maybe this log would give you more insight into the source of the issue? I'll do further troublesh...

It is version 2.6.7.0

Did you ever get this sorted out? I've been having the exact issue.

Hi Hondata, I have recently been having issues where closed loop stops working randomly, usually after a few minutes of driving the closed loop function completely turns off and my s.trim and l.trim "freeze". Then upon restarting the car, closed loop begins to work again, but only to stop ...

If 185 ECT and 135 IAT are your normal warm engine conditions then both compensations should remain at 0% for those values. Post up your compensation parameters. It could be that your cold ECT and IAT fuel compensation is a bit high, which makes it start up cold and run well but once it is warmed u...

You'll want to be watching your sensors and compensation values simultaneously when this occurs to determine whether or not they are a factor. What is your ECT and IAT reading when it happens? How much compensation is it putting in? Is your closed loop enabled and what is your S.trim? Without track...

Here's another datalog of the occurrence, I've been stuck with this issue for quite some time and the car runs great other than this.
Which parameters can I change to increase the fuel during hot restarts?

Hi guys, I finally came around to taking a datalog of my situation. This time it wasn't as bad, as I waited about 5 minutes before I did the hot restart. Although on occasions when I wait 20 minutes or so, the car starts up at full lean (20+ afr) and then it comes back down to the 14's after a few m...

Hi guys,

I haven't had much time to work on this car as I don't drive it much, but I will try to replicate the issue by next week and post a datalog so that it can be reviewed by Hondata.

I have my anti lag set to 100 units of fuel, 25 degrees retard and activation set to 5300 and launch control set to 5500

Anyone?

What can I do to fix this lean hot restart issue?

I have decreased the fuel decay tables and added more post start fuel and I still haven't had any success in fixing this.

The car runs perfect, other than the lean issue upon hot restarts.

Thanks!

Hi guys, I have narrowed down this issue -- what seems to happen is my idle could be at a solid ~14.7 while fully warmed up at 180*F ECT and 80-100*F IAT, but when I turn off the car and restart about 5 minutes later it while hot, it leans up to 18-20+ afr for about 30-60 seconds and it then stabili...

Hi RofromNorCal,

It appears that you have a hot boost cut set to -14.7 psi. You might want to remove the negative symbol, upload your calibration and test again to see if you still have the same issue.

I had this same issue on my car today. Everything had been running good until I updated my smanager to the newest beta version and made changes to my launch control and uploaded the calibration. As I was driving, my short term fuel trim suddenly went down to like -20 and the car kept stumbling and n...

Did you ever get the flex fuel working properly? I have been thinking about using this feature, but would like to get input from someone who has experience with it.

Thanks!
