AT frs rpm issue

When you tap and let go of the throttle lightly, is it normal to see a drop in the rpm (below 500) and then slowly rising depending on how much you throttle you tapped? Is anyone else experiencing this issue?

Ive experienced this. I don't think its an issue per say... but I would think there are more knowledgeable people than myself that could say yes or no.

@soulreapersteve @go_a_way1 Glad I'm not the only one but it's more noticeable when you are in P, N or accelerating from a complete stop. The weird thing is if you're in sports mode the problem goes away.

Only really happens when in N or P I always give it too much gas off the line to notice haha! It could also be the tranny moving the fluid around and probably has to do with the torque converter is another guess as to what it could be haha!

@FRSBRZGT86FAN Does this happen in your 2015 frs?

I drive a 2013 and according to @go_a_way1 status it looks like he has a 2013 too.

Yup I have a 13 It has done that idle dip thing since she was brand new. I have also had all the updates done but I am also ECU Tek tuned so that might overwrite the update changes

Mine is '13 MT and I notice it does this sometimes. When it does it, it keeps doing it. But when it doesn't, I can't recreate it no matter how many times I try. I've never worried about this, so I didn't mention this in this forum or to the dealer.

It used to when I first got it, however now after a TSB with a TCM logic reflash and with an OFT tune I've edited a lot I don't really notice it at all

Now that there's a TCM flash TSB, I wonder if any tuners can find out how to do that.

Highly doubt the 15s have a different TCM than us.
