It looks like the stalling issue with the car had to do with an air leak in one of the couplers during installation.

It may be just the air-leak and not the kit or tuning that is causing the stalling issues on my car.

The car has the new turbo in it and clutch/flywheel installed.

Mike discovered an air-leak in one of the couplers which may contribute to the stalling issues with this car.

It may not be the tune or the kit that was the source of problems but a minor installation oversight.

So far, they have installed the upgraded turbo and clutch/flywheel.

Next step is to optimize the exhaust system and install the coilovers and sway bars.

We have a customer from PA that is supposed to be bringing us a z4m. We are looking into using an e46m ecu and engine harness.

interesting.. but what a shame to not do the MSS70.. its a very advanced ECU and might me better than MSS54.. it has Alpha-N as well..

try it while you have the car at least?

I wouldn't say the MSS70 is better than the MSS54. Newer yes, but not necessarily better. The problem with MSS70 is that its internal variables lack the headroom required to support the amount of airflow an engine with a turbo kit consumes. This means either an in-depth disassembly and rewrite of the OS (costs too much money for the project) or a 'fudge' in the tune to make it work in a half-ass manner (not my style so it isn't going to happen).

Alpha-N plays ZERO role in this, but the MSS54 also has that capability.

Aside from the cluster.... that the software in the MS45 is, it did make me wonder why they didn't just go with that hardware instead of yet-another-DME variant with the MSS70. I assume the reason is for tighter emissions output for the update...unless it was to integrate with the rest of the vehicle's electronics better. What are your thoughts on the reasoning, Nick?

I hope the jerkiness of the UUC feramic clutch on my SMG M3 Vert has nothing to do with the TCU needing a tweak too. Must go back to a UUC organic clutch now.

I don't know why I read each of your posts as a jab. The Uuc feramic worked exactly as it was supposed to at wot, and engaged smoothly from a stop with light throttle. If you gave it moderate throttle the car would shudder a bit until the clutch fully engaged. I ordered a set off organic discs because I don't think you will be happy with the clutch engagement in traffic and I am swapping everything out for you since it was my choice to try the twin feramic for your possible higher power goals.

Even the HPF (Southbend) Stage 2 SMG Feramic Clutch has a little bit of jerkiness to it starting in 1st or 2nd gear from a stop; you get used to it once you learn the precise throttle position to prevent that.

Agreed.

In that case I apologize if this is normal for a feramic clutch.

No problem, just making sure everyone knows we are on the same team.

Sheesh....

How much more power is needed? lol
On a conservative tune, reasonable kit price and tech support to boot,
they've offered a 10 second car upgrade.

I know...I know...
there's never enough. I know the illness.
