Car goes rich as hell coming off throttle

[MantisX]

Anyone else experiencing this? Ive tried disabling fuel cut and tuning my tip out, but Im not able to get it to move from the 11.5 and sometimes lower AFR when raising my foot partially off the gas. It stays there too until fuel cut kicks in or I push back down on the gas. Any ideas? MantisX

tune the first 2 columns

Mine does that too, sometimes into the low 10's. I have tuned the first colums, and played a bit with tipout, but nothing seems to get rid of it. I havent really payed too much attention on it, as its not really a problem, but it would have been nice to get rid of it. I guess its probably something I dont understand, but I'll try to make a log that shows it this weekend, maybe someone can help

When making my basemap I normally set my first column to near 30in/Hg, and the values are always around 4 near idle... just hit the lower selection value button with that column selected to get it down that low, then the second column 's value to 1/2 way between 1st and 3rd; the first column only needs to be really low, second will be easy to tune.

You mean you set all the first column to 4? I've tuned the first and second column when deaccel donhills with fuelcut disabled, and by just standing still and reving. Its hard to nail the AFR's, but I've gotten somewhere between 13-16 I think... I have never tried setting the first column that low, though, that might work Here's my cal if you want to take a look

best thing is to get your fuelcut set properly and you'll never be reading from those columbs.

So you use fuel cut delay = 0msec? I'll try that next time I take the car out for a spin.

no not 0ms.. that will be annoying to drive, I usually use 300ms or so. seems to work pretty well.
