Rear Diff Options - Power Oversteer Found Here
we've moved on from that flash bro
sweet. you are a very early adopter of the rear diff. new one should be very nice
The new diff feels awesome. Havent been able to go out and track it to really see how it has improved over my previous TRE diff. After talking with Jon at TRE, he had said that my old rear diff had a pretty bad pinion bearing. It was one of his older works, done back in 2006ish. He had said that he has since improved and made tweaks to make these even perform better than my earlier design he used to build.
Even just spirited driving it feels like an improvement.

---Its old school, but the Gruppe-s gets the job done.

--- I may have an opportunity soon to go to a track event so hope to test out how improved it is. It will also be its first track event since the rebuild so Im pretty excited.
are you noticing much difference? i've had the gruppe-s and the acd tuning version, both of them had a little too much initial lock up/binding/understeer for me - i hear english racing can make the car loooose (autox), i'll be getting it pretty soon here

I gave Aaron my car specs so this tune should be right on the money.
Thanks for this thread, Kyoo, and thanks to JDavenport for letting me know. This is unbelievable - it's like waking up in a new era with a magical unicorn mod now being available. I have to get this on the Evo for NASA TT, so I'm going to purchase one from somewhere right away. I have a Shep trans and have worked with Shep professionally for a while, so I'll talk to him first, but it's good to know there are several options available.
What is the deal with the ACD reflash? You can't just add that into the flash? Does it need to be purchased from someone as a specific offering?

ACD Tuning thread is in my sig, I'll PM you more details.

Reading the ACD thread now.
congrats - sounds good, good luck with everything. shot you a PM of the quick and dirty details
Hes just busy building badass drivetrains. He is not active on these forums due to all the bs and politics, which I totally agree. From my experience I have always been able to reach him when I call between noon and 2pm pacific time. Also leave an email with a contact phone number.
