Seeking Input on Whipple Tune Functionality

[rtg]

Running the tune that Whipple provides. Now version 2-3. I have two issues I am tracking down.

First,

That has only happened once, and I can not reproduce. In "D" and going from 1st to 2nd. Did not catch 2nd. Rev'ed up until I let off the throttle and then it went into 3rd. Will just keep an eye on this.

Second, (seen this with all the tune version)

Accelerating NOT WOT (around 40%-50% Throttle) so closed loop mode. Pulls hard then I get some bucking around 6500+/- RPM. Logs show Throttle not moving but hard to tell if the Tomahawk is showing Commanded or actual throttle position. Wonder if when the RPM gets close to where the throttle is set the vacuum comes up and the bypass opens. Since Tomahawk does not report calculated vacuum hard to see of the bypass actuator is opening. Lamda remains around 1.00 on both banks. Timing looks good as well. No pull back.

This scenario is the one I am trying to understand. Collecting some more logs but the weather is too cold of any kind of safe pulls especially WOT.

Other than these issues Driveability is excellent.

My 2018 PPL2 (manual) is also “ bucking” at 6500 RPM (Manual) I was told the rev limiter is set at 6200 RPM which is why this is happening this make no sense because it didn’t do it before the Whipple was added and it doesn’t do it every time. The dealer nor Whipple can get the rev limiter to move higher at this point. Very frustrating.
All work has been done by local Ford dealer that has a performance division.

Bucking under part throttle and higher RPM seems to be a constant issue with the whipple tunes. I had it on my 17 when I was running the stage 1 and 2 whipple tune. Completely gone with an aftermarket tune. But I also closed the gap on the plugs another .002" because the tuner was seeing spark blow out under those exact conditions with them gaped at .028".

Do you know if the blow-out showed up as a misfire error code?

I am not seeing that error code or any code for that matter.

Thanks,

I did have random misfires with the whipple tune, but my plugs were way out of spec, like .030-.032". Once I got them all down to .028" it never popped another code, but the bucking/surging feeling was still there. It was actually still there with the aftermarket tune, although not as noticeable. And that is when the tuner saw in the log that I was getting spark blowout and recommended closing the gap some more. After that it was as smooth as butter.

I'm running the Whipple tune and a stage 2 on my 18 manual car. I don't have any issues with bucking or anything with mine at this point. When I first installed there was a quirk in the first tune that had my throttle cutting to 50% at about 6,200rpm, regardless of the fact that my foot was all the way to the floor. Whipple sent me an update that fixed that, and have had no issues since.
