After years of working with Cobb Tuning we wanted to be the first shop to first hand test the new BMW Accessport! We started using Cobb when they were strictly Subaru, and have stuck with them through the years. We now use there software to tune Subaru, Mitsubishi, Nissan GT-R, and Mazdas!

You couldn't ask for a better group of guys, or better technical support than you get from the guys at Cobb Tuning! If you are unfamiliar with them rest assured they are one of the leading companies in the performance industry!

As many of you may know we have been tuning the turboed BMWs for almost a year now using our own software. However we are very excited to jump on board with Cobb and can not wait until they release their AccessTuner software to the US ProTuners! At that point we will be able to create a custom map for each specific car to optimize its performance! Cobb always leaves a little bit of power on the table for us ProTuners

As usual we were pleasantly impressed with the BMW AP! The install on the car went very easy and quickly! The handheld interface is easy to use and learn. It gives you the ability to log, check and reset codes and much more.

The tune itself is just what you would expect from Cobb and a STG1 tune. Power delivery is like stock only more of it Throttle response, tip in, fuel trims and boost levels are all solid and very safe!

One of the other great things about this devise is that you can simply uninstall it from your car, the AP loads the original map back on your DME and vanishes Like it was never there. *wink

Please feel free to email or PM us with any questions you may have!

Here is the baseline and Cobb STG1 flash overlaid in a graph. This was done within minutes of eachother! The car never even came off the dyno between maps.

91 or 93 octane? (I assume 93 your in GA), but asking.

Those numbers seem to fall in line with the impressions of the Stage1 map on my own car. What transmission is in the 135i and what type of dyno are you operating?

[vasillalov]

Pretty impressive, I must admit. GIAC S1 shows 55 wheel HP and 55 ft lbs of wheel torque gain over stock.

Are there any other modifications?

That sucks man, why didn't you get stage 2 ?

The 135i used was a manual 6speed, and the numbers are DynoJet

No sir, the car is bone stock with 40k miles on it. Never been modified.

Thanks for the questions guys.

Stage 2 is coming in the spring. I need intercooler + intake.

[vasillalov]

Cicio,

What was the boost level @ max wheel tq?

[CICIO]

Thats a great question. I wasn't actually in the car...I will ask my tuner and get back with you ASAP

I just talked to Doug about it. He said it ramps to 15psi then tapers on the top end to 12.5ish.

Looks impressive. The self contained install ability of the Cobb units is very attractive. That is what I like so much about the JB3 & Proceed units.

Thanks for your input! Thats a very good point.

That's pretty impressive just stock with no dci...are you going to dyno anywhere else? Those numbers are really good with just 93 octane and 12.5 sustained, that looks just as impressive as other dynos with dci and more boost. Where is Cobb getting more power from? The air box gets pretty restrictive at those boost levels.

Cicio, thank you for the quick response! It looks like COBB Stage 1 sits right in between GIAC Stage 1 (13.8psi) and GIAC Stage 2 (16.8 psi). This explains why COBB makes a bit more power than GIAC S1.

It looks very very good so far. I am curious to see what COBB S2 will make.

[Sniz]

this is a great great option for you guys

Actually the factory airbox makes more power than aftermarket systems until you get over 400whp. We did a direct test with STG1 car and it made no difference.

The real fun part will be when the ProTune software comes out.

Usually after 14 PSI the stock airbox is a bottleneck..... dont shoot the messenger.

lol...its a common misconception actually. I was running my 135 on the dyno at 17.5 PSI for some testing...we bolted on an intake system and the car made ZERO power The factory box is very very well designed.

don't shoot the messenger

Happen to have those dynos...or any other proof...both Vishnu and terry and countless other intake manufacturers have shown countless other dynos to prove the contrary..please bring proof and numbers to back up your claims everyone else has. Plus Mr 5's intake modifications show to be better plus the almighty dinan system, I understand that inflating numbers or downing other products are part of business but the one thing everyone has agreed on is that an intake is necessary for higher than stock boost. Hell people have done flow benches of the stock intake, sorry man wrong hornets nest

[Imperator]

Is it possible that reading comprehension is not your strong suit? The car is a 135i.. it has a different air box.
