Hondata

Hello, I've documented some issues with my Stage 1 tune in a different thread. The consensus is my fuel was not up to snuff and the ECU learned some things that led to pinging at 3/4 throttle even on the 93 Octane I was running after getting through the crappy fuel from the first tank.

I flashed it back to stock and ran about 3 tanks of 93 through it on the stock calibration then re-loaded the Hondata baseline Stage 1 tune and did some data logging. I started with just normal around town driving and saw no knocking or increase in knock control. After that I did some progressively more aggressive runs. I logged a couple of the pulls after seeing no knock control increases in the first few tries.

I'm not quite sure if I correctly did the process of uploading the calibration I'm using. It should be the baseline Accord 2.0T Stage 1 calibration included with the FlashPro. I THINK I got the right thing. When I found the one I believe is uploaded to the ECU I renamed it so I'd recognize it when I went to upload it here.

I also uploaded three logs from normal driving and some accelerations. If anybody can take a look, I'd appreciate it. I think everything is running as it should now that I've got known good fuel in the tank!

I'm considering whether or not to shift to stage 2, but I guess I want to make sure this one is safe first. Thanks!

Your long term fuel trim is decreasing and is pulling 8% by the last full throttle run. This means it is running rich. You can try the stage 2 and see what it does.

Like Spunkster stated. Its running a little rich. I noticed a few counts of knock on the part throttle log but its not a concerning amount. I would run the stage 2.

Thanks for the feedback Spunkster and Ed. I went back and looked at a couple logs from my previous load of Stage one and I was getting Knock Control in the high 80’s to low 90% range. Obviously it’s happier now.

I’ll load Stage 2 and post the results.
