Got my Flashpro a few days ago and just running the basic +6 PSI calibration. This is the Canada 2017-2018 version +6 via Sport and FTS

Only change I made in settings was to Disable rev hang.

When I go from completely off throttle, to full throttle, or even half or quarter throttle, the engagement is so harsh and abrupt the car literally 'bangs' from the jolt of getting on the gas again, very strange it didn't behave anything like this before. If I do anything other than very very lightly feather the throttle back on it's very jerky

I had a RSX Type-S with a Kpro many years ago and I remember something similar I had to tune in the fuel settings for this but I can't seem to find the right place to look for trying to resolve this.

Also, +6 from what baseline? I'm getting 22 PSI max is this normal? It also doesn't seem to change with Sport mode, when sport mode is off I still get 22 PSI, I was under the impression most of the changes only kick in with Sport mode on

Lastly, to view the Fuel, Ignition tables does the Flashpro need to be connected? I was trying to compare base cal vs the +6 cal on my PC to see which numbers might be worth trying to adjust but I can't view any of those table values.

Cheers!

What modifications have been done to the vehicle?

Completely stock, it does have the HFP package but that's probably irrelevant

Have you tried it without disabling the rev hang?

No I haven't tried any troubleshooting measures yet, just trying to get a sense which settings might be the best area to look into first

So I re-tested with rev hang enabled, and the throttle feels normal again.

Does anyone know what table values get changed by that rev hang checkbox so I can play around with them and see if I can smooth it out? I'd really like to keep it disabled

This is controlled by a Mod, and there are no tables you can change for this.

there is another section where you can adjust the rev hang, it is on the fuel tab near the bottom, its the overrun fuel cut delay,

this adjusts how fast the injectors shut off thus increasing how fast the revs start to drop,

I have mine adjusted a to give a little bit more sporty feel at
