Installing COBB AccessPORT on My Z4!!
Hello. I kow that according to COBB's website they don't offer a specific tune for the Z4 yet, so I called them. They were happy to talk to me.. they said they would give me a 10% discount and free shipping if I would try it out on my Z4. They said that there is a small chance it does not recognize my ECU. If that occurres I will perform a ROM dump, send it to them and they will send me a firmware update within 5 business days. From what I can tell, COBB is a reputable company with tons of experience in ECU flashing, although only since this year for BMW. As part of the agreement, they would like for me to send them data regardless of how satisfied I am with the results. Also, they have a 30 day money back garuntee. What can go wrong... LOL. I'm excited, wish me luck!

Sending COBB AccessPORT Back
I finally tried the accessport this weekend. Last week I tried it, but it didn't recognize my ECU. No problem, downloaded it and sent to Cobb. Within a couple days, they had a beta version for me. It installed fine and showed good acceleration during moderate driving. However, at WOT at around 30 mph, the RPMs shot up to 7k but I didn't really go anywhere. The RPMs would go down to 4k and the DCT would engage and I would accelerate. It felt like it was accidently shifting into neutral. I was able to repeat this behavior every time.
I talked to Cobb and told them I didn't have the stomach for tuning my Z4 remotely. Afraid I would ruin my transmission. They sent me a return label and were very pleasant about the whole thing. I'm thinking of going with ESS. I won't a company that has taken the DCT into consideration. Any suggestions would be appreciated. Thanks. |

Go with the ESS tune. We currently run it on the 3D Design NA car and it is incredible. PM me if you have any questions

I've been using Cobb with my Z4 for a little bit. Right now it's off since I just got the newest software from BMW when I got my roof serviced. Cobb is still working on the new firmware for the ROM.
But my experience with Cobb on the V4 maps was pretty awesome. I had the opportunity to drive a good 4 hours right after installing it with my downpipes and exhaust. The car really pulled a lot harder... With the Cobb off the car right now, I really don't enjoy the stock power of the Z lol. |

AR Catless, I was only on Stage 1 as a matter of fact. My HPF intercooler is on it's way and I just did a simple drop in filter to avoid heatsoak issues - As soon as Cobb gets the updated firmware for the new ROM, I'll have updates with Stage 2+FMIC. Unfortunately no dyno and I believe it's pretty tough since I have a DCT.
