I'm really not qualified to say, other than I have had no problems over the last 6 months.

I also don't rev to 4k rpms and drop the clutch. Usually only WOT in 2nd gear and beyond.

My car has the same setup as Wedge (auto v 6MT), so you can find his video's on youtube of ShiftS3ctor events and factor in my drive-train loss/extra grip

Thanks for the info. And you've said you are running 100% e85, what fuel upgrades have you done? LPFP? what else??

I will be in Midtown about 4 blocks east of GT. I posted in the Atlanta thread in the Southeast section. I am going to miss having a garage to mess with my car in... need to find a decent shop in the area.

Just the LPFP and ECU flash from Vishnu. I'll be getting new firmware and maps next week to beta test as well.

If you remind me, I'll post logs once updated.

I got an OEM dual mass flywheel with a 2+ so your mileage may vary, but, I love this new clutch. After 500 miles of patiently breaking it in, it grabs hard, is easy to use, pedal feels no heavier than stock at all to me. Engagement point is the same. This is the best clutch I have ever used on anything. I wish all car clutches would engage so precisely.

The clutch did shudder during break in (initially smooth, then shudder, then shudder gradually reduced). Over time, shuddering has been getting less and less. But, after 500 miles, it wasn't anything I noticed. Most of the time, I get no shudder. I can even engage the clutch with no gas pedal and no shuddering.

Well, now I have moved out of the Bay Area, so I will eagerly await new maps. I am still getting that dreaded engine error at partial highway boost. Yet, on closed courses, full boost through 150 mph produces no errors. It's a real head scratcher for me.

The start up should be really smooth and the meth logic is changed so that it is primarily used for additional cooling, because he is getting all the octane out of the E85 that the car needs. At least that is what I think he said.

Shiv explained the code issue to me as well, but it went in one ear and out the other. The gist is that it is simply a software issue that has no negative effect on the engine. That is why you don't loss any power when the code is thrown.

Glad the DMFW is working out. It is the lightened SMFW that has the lound chatter. I still really like the functionality of the clutch regardless of the lack of refinement.
