Yeah i cleaned up the TB and flushed out the upper (which was nasssty dirty) and cleaned up some of the sloppy edges on the oem upper. I also did plugs at the same time ( all done last summer). The only thing I couldn't clean out was the lower.

I now have r2c, ART TP, aftermarket y , fujitsubo axle back. No tune yet which could clear up most of the issues?

Yeah. Rule of thumb I've heard is that if you have exhaust AND intake mods, a tune should be warranted to gain max power.

Csc failure as of 3 days ago...car is at Z1 getting the master slave and CSC elimination kit installed, so this part of the build is going to be indefinitely postponed for me.

Fml

:ohsnap1:
ugh! Sorry to hear! My CSC went at 85k (last summer) so I went with the heavy duty and a stage 2 Southbend clutch and quiet 1 piece flywheel.

Didn't know about the elimination kit at the time! let me know how it drives with that kit!

So firsts, I think the design alone is worth the cost. I was going to get this modification eventually, but...well, ish happens. The fact that they repositioned the hydraulic actuation to OUTSIDE the bell housing will save much heartache and smouldering pockets for not having to drop the transmission.

Clutch pedal pressure is amazing, as is the grip of the clutch now. I used to experience a spongy feel and a lag when I would initially shift I to a gear. This completely eliminated that, there's a clear cut point at which I feel the clutch engage, not to mention the smoothness of it is second to sex. It's like a switch now, either I'm in gear or 8m not. No more shuddering because of revs not matching exactly. What little power there was left finally could make contact with the ground, and the feel of the throttle became snappier too. Still have the oem clutch and flywheel, around 60k miles on it. Zach and Rob at Z1 said that it looked pretty good still...this was an unexpected expense, so I left it in. I'll eventually get the Z1 clutch and light flywheel when this one goes in another 2 years or so.

However, it's pretty damn expensive if you don't do the work yourself...I paid over $1300 to have it done properly at Z1. Pretty much what I was going to use for the ecu and tune...:crying:

Yes, 2008 can tune with Ecutek. :) :) :)

has anyone tried with 5speed auto?

No can do, anything post 2009 is 7AT.

Sry mayne.

Since no one have tried it beside it's all hear say then I may be the first to try it. :stirthepot:

You physically cant. There isn't enough memory to house the full RaceROM, so you'd just be getting a basic tune, nothing more.

Unless you have some rareason jdm-as-fuq ECM that is compatible with a 2008 5 speed and has more RAM.

And no, you're not the first to try it. Autosport engineering (if you've even read this thread) has been doing it for a few years now. @tommyboykim on IG has an 08 with a 2010 IPL ECM already running his setup.

I'm just looking to have basic tune along with ignition timing (this is what I really need). Yes I read that Tommyboykim has swapped over but his is MT. I have not came across someone with AT yet. That's why I was asking.

In case anyone is still interested, I have an 09 ECU working on my 08 5AT G37 and flashed with EcuTek and Racerom - it can be done !

Reach out for details if you're interested - just need to find a close match (feature for feature) donor ECU.

If anyone needs an ecu that will allow them to run FULL ecutek WITH RACEROM on their 08, PM me, i have them in stock.
