RPMs rev very freely when it's hot outside

[WolfDampf]

I always thought I needed a lightweight flywheel to shift quicker and for my RPMs to move freely. But I realized that whenever it's hot outside I can shift 1st-2nd immediately as the RPMs just tank vs when it's 80 degrees or below they take 2 seconds to drop before I can shift to 2nd

Here in Arizona where is nearly always 80, I feel the revs are too slow... Though I love the dual mass while going through the mountains, not nearly as much slowing. I still think I'm going to switch to a single mass when the clutch goes

So I actually did switch to a single mass flywheel. I'm currently running the whoosh stage 3 kit with the SMF. Its about 8lbs lighter than stock dmf. The weird thing is I haven't noticed any difference in how long it takes for the RPMs to drop or rev up. This leads me to believe it's all in the tune. And now realizing that whenever it's 95° and up over here the RPMs drop and rev way freer leads me to think it is emissions related.

The throttle is staying open to burn off fuel. If we can get the throttle to immediately close when letting off the throttle the RPMs should drop. I'll ask Dizzy about this as I'm on dizzy e30(loving it btw)

I'm building a custom corn sensor so I can load an e30 tune, so I'm stuck with dizzy stage 2 91 for now... Don't forget to update us with what dizzy says

Dizzy gave me a new tune to try out. I'll update after a few days of driving as I don't drive very many miles

The new map made a big difference on how fast the RPMs drop. I now KNOW that it has nothing to do with a heavy flywheel.

Jason said "So…it’s kinda strange.

Sometimes adding duration, I find has the opposite effect on some year vehicles. So I get a customer (like you) requesting a change, I make the change and it does the opposite. So I go in and adjust it the other way, and then customer is happy. I can’t explain it, and it honestly has not happened enough (or is even that big of a deal) to bring up to Cobb.



So attached is another map trying the other direction, lol."

Interesting maybe I need to reach out to Jason and have him change the tune in mine just to see🤔🤔
