Evo IX revv hang?? Anyone??

i just got my evo ix a few days ago and noticed it has a rev hang between shifts it's quite anoyying. especcially at WOT it gets on my nerves.

this has been discussed. Trying searching this forum for more information that you will possibly need.

Cliffs: still being working. Suspicion is with ISCV tables.

Open your rom with ecuflash,,

Find the iscv table

Adjust the #136's down to 115 or so

Flash back your modded rom.

If the problem persists it's time for a boost leak test.

Good luck with your project,,,

As for the tuner comment, I'll choose to "stay out of the politics".

From: somewhere testing various tires, brakes, and suspensions.
Search by relevancy and which specific forum you want to look in. That helps narrow the field.

This is not the fix to this issue. Please do not alter these values.

Like i said, it is suspected that ISCV has something to do with it. There are numerous tables but nothing has been confirmed as the correct one. Not sure who your tuner is but maybe they have some magic that the community is not aware of.

PS..

I'm not going to get into a heated debate with a mod then get my account disabled.

I'm done responding to this thread and the op can pm me for any more assistance.
