Yeah, really curious to know. I had some pretty serious problems with the original VT2-500 tune on California 91 octane gas (highest available here, always from top quality gas stations), and they revised it for me, but I'm not sure if it's been updated again?

Is it possible to apply their updated tune with the ESS flasher unit, or do you have to send in the ECU?

No he only replied that, the next day.
I don't want to engage a discussion with him about e46 M3 tune and Z4M tune.

Aww man, that's a bummer.

Someone posted a dyno on their E46 M3 with the updated tune. He stated that his former low end throttle stutter is now gone. Even more impressive is that his top end pulls very nicely based off what was depicted on the dyno.

Do you guys have similar issues with your Z4 VT2 kits? Throttle stutter around 3000RPM and below?

1 block from my house, the main belt jumped off. Upon closer inspection, one of the tension pulleys broke and scraped against one of the other pulleys. Now both need to be replaced. Gotta find the part numbers. At least the belt doesn't look damaged at all..

These pulleys are such a bitch to take off. I don't even know whats holding the tensioner pulley on. I removed the central bolt, but its still stuck in there

Im working on my car and had a look form underneath, it looks like just the center bolt holds it.If i can help in an other way let me know.

i agree and its getting way boring now...... the z4m tune behaves in exactly the same way that the e46 tune behaves which forced ESS to do a tune update and apparently its brilliant and giving more top end!!! Im getting really annoyed how the z4m community seem to just be left out all the time, no updates, nothing....

[ZStig]

Thanks a lot! Do you it beedub have the belt diagram from ess by any chance?

You guys are awesome. Thanks. Looks like parts are gonna run about $200 for this fix

[ZStig]

What parts did replace?

[ZStig]

Updated BMW Hydraulic Tensioner assembly + its pulley and new bolts $112.95
Water pump pulley $44.87
4 new water pump pulley bolts $3.95
New custom size belt $20
Barely used S54 Oil filter housing $285 shipped

While at it, I did a full engine oil change, fresh power steering fluid, and supercharger oil change

+ about 6 hours of labor on a friend's rate since the supercharger, and alternator had to come out. The oil filter housing is a bitch to get to


there goes my mod money for the next 6 months
