I've ridden in a couple of cars with PSS9 kits, and they are a fantastic bit of kit. Suspension is next on my modification list, and I'm currently trying to find as much information as I can about all the options (not too easy!) I guess if you get the PSS10s developed, they'll be available for resale after?

I got in touch with TCKline. Apparently one of my e-mails was buried and they inadvertently blew me off for a while. I spoke with Pete about their DA Smart coilovers. Of course they're selling the stuff and have rave reviews, but I'm concerned about the mixed reviews you speak about. Maybe you could PM me with what you have heard. I am preparing to place an order very soon and don't want any surprises.

They have a US distributor so you can get a chip from Kelleners USA.

ECU Tuning
ECU Software Performance Upgrade
1. Optimizing engine operating parameters
2. Removes electronic top speed limiter
3. Unique Individual Custom Logic Tuning
4. Increased Rev Limit

Engine HP Gain: +12
Torque Gain: +5
Retail Price: $598

What the heck is the top speed limit anyways? I've managed to get my Z4 up to 250km/h before.

Noticed this:
KS Pulley Set
Kelleners Sport Performance Pulley Set
Replaces stock pulleys with ultra light precision
manufactured aluminum alloy pullies to save and
reserve the rotational momentum of engine crank
: Power steering & water pump pulleys

Engine HP Gain: +10
Torque Gain: +9

Are you kidding me?! +10hp from pulleys?

Unfortunately, this is only for the older M54 motor, not the N52 in the 3.0si's. Turner Motorsports in the states also has software for the M54, but nothing for the N52. I asked them about this and they said that it's being worked on, but not to expect anything before 2009. Maybe if enough of us 3.0si drivers ask nicely it'll happen a bit sooner...

If you want the Kelleners stuff, call them in Germany and make an arrangement. The guy in Chicago that uses the Kelleners logo is NOT supported by Kelleners here in Germany. Eisenhaus is a shady company.

Yeah...just make sure you start off with...Sprechen sie englisch (Sprecken zee english)? hahahah

A little update...

I was back with Kelleners-Sport (Germany) having my Evosport M3 Headers and Evosport high-flow cats installed. During the installation process, they did a pre-dyno for a measure of gains. I did the ECU flash on my car several months ago and the ECU has definitely adapted well. The car showed 348 ps or 343 hp. The only thing I have changed was to install a BMC air filter. I now have the headers and cats and will allow the car to adapt before we dyno next week. The car sounds great--like a euro Z4MC now. Not too loud either, but you get that pop an burble as you let off the gas when the raw fuel hits the cats. Oh yea, there is the M3 CSL rasp... Gotta love it.

This weekend: RPI Scoop

UUC short shifter, lightweight flywheel next...

ESS 550 supercharger later this summer...

I think i am around or close to that 343-348 hp with the rpi scoops but no software upgrade...keep us posted

i've got a question re: ESS ECU upgrade.....for the Z4M
1. is that just a flash?? or is the ECU physically removed and worked on
2. if it is 'flashed' is it detectable by dealership??
3. how can it be turned back to 'stock'

The ECU needs to be sent to AZ to be flashed. Turnaround is next day once it is received.

If the dealer looks into your ECU they wcan detect it. Most dealers will never look for software unless you have a problem with the car that requires them to check it. I have had software on my 2 M3's and this car and never once has any dealer ever mentioned it when it went in for service.

It can simply be re-flashed to stock at anytime if you have a shop nearby that can do it or the dealer can re-flash back in a stock file. Your stock file can be sent back to you via Email or to a shop that requests it.
