learn to tune.

your AFR targets can be 10:1 at idle but it's not going to hit it if you don't tell the MS to use EGO at idle. You need to tune your fuel map, im surprised it can even idle that lean (assuming you didn't botch the AFR calibration).

I'm in the process of learning now. Under load, the AFR's look solid IMO. I'm still working on idle and returning to idle. I calibrated my AFR gauge according to the instructions in the manual.

And to be fair, that video was taken with the horrid exhaust leak. The AFR's are a lot better at idle now. I will post a new video either today or tomorrow.

okay, yeah an exhaust leak will throw off readings like that.

I am going to look into AE and the fuel map after work tonight, though. I might be coming back for more tech help! Haha.
