no it was something about the cobb resetting the ECU or something.. the system automatically fails you if something is wrong. It might be just a new york thing

Only mistake I made though is buying it in the fall... cause I didn't receive it till the snow started to hit and I havn't been able to log much cause of the shitty roads. I've had mine over 3 months now and only sent in one set of logs. You only get 6 months worth of logs that you can send to MM when you buy an access port from him. Thats more than enough don't get me wrong but unless you have clear roads year round I'd wait till spring to get it so you have more dependable weather. That was my dumb fault... What happens after that 6 months? You have to pay a certain amount or is all up to you from that point on?

Im thinking of buying a cobb access port for my 05 rx8 right now its bone stock except from a drop in k&N filter and the intake mod where you take out the 2 walls in the box. Will the cobb improve HP or acceleration on a stock model like mine? is it rele worth the 600 bucks?

The gains you can get with a new tune on a NA depends on a car by car basis.
If your stock tune is not reflecting for ex your maf scaling correctly you can get very rich conditions at WOT open loop, you can test this with a standard OBD2 device monitoring LTFT and actual AFR while doing a WOT run to redline.
If your LTFT is for ex 10%++ and you have a rich AFR curve going for ex under 11-under 10:1 the gains from a new good calibration will be greater for that particular car.
But if your AFRs are already in the mid 12- 13.8 in the upper rpms area the gains will be smaller.
We are not talking huge HP numbers here but every small increase you can get is good combined with other mods (correct me if I´m wrong).
The cobb ap with ATR will also give you ability to do a lot of other things like OMP rate, radiator fan start/stop adjustments, cel masking++.
I say its worth the money
