Tuning HELP

[Metraman]

As you can see my Jeep runs well, however while stopped when i wack the throttle is stumbles for a split second. Before I go trying a fix, I thought I'd ask what's the solution?
Thanks

Old school thinking is too much fuel, modern thinking is not enough air.
1st I would try air flow , add a little g/s in that area, if it gets worse, take some out, Na I take g/s away when I have a stumble and works 9 out of ten times, the tenth time
I look at injector values at that rpm, might need to be trimmed down.

I had a mess of a time with stumble on a custom 265/270@50 cam, finally sorted it out with injector mapping

Thanks
I see a lot under airflow, the sensed MAP is disabled a little more direction would be greatly appreciated

I don’t know the tune, best advice is to look at a log, check where you have the stumble, log throttle v, and TAF, on airflow table add air at that throttle v on the table, if it’s better, great, if it stalls, return to original setting. Log it, then take some air out, , might need to do the same for the v setting above or below.

Is this a new issue or has it always been there? New issue, try reloading the tune, . You would be surprised at how often that works. My 2020 1320 challenger will go into a idle surge at exactly 101 hours since last time the current tune was loaded, mileage doesn’t matter, 100 hours on the mark, at the start of hour 101 it starts its surge deal.

It's a new jeep to me my previous one was stolen. I'll try loading the tune tonight.
Thanks

Well I reloaded my tune I've still got the stumble. Going to move on to my next option.

What's you wideband reading at the stumble and directly after it?
Do you have a log with the wideband readings?

[Metraman]

No wide band reading. Will the HP program do that?

Post a log , point out where it's happing in the log, those who'll help will point out what channels are needed , it'll take some time.
