Correct. It is the only option available that provides us with what we need to do custom tuning. There are a couple other options available for the N54 but nothing that works nearly well enough in our opinions to use and certainly nothing available for the N55.

Future upgrades include an ER charge pipe with an HKS Bov, and a Cobb FMIC. Apparently the 5" FMIC works just fine.

PTF does not charge for a retune with these FBOs unless you want maps for 100 octane or E85.

Allen, can you explain VANOS tuning and how you go about making adjustments?

When first experimenting with VANOS tuning you have to spend a lot of time on a dyno. With VANOS tuning it's not as much about peak gains but how it can shift the power band and the same adjustments made at 5.5Krpms may not work at 3.5Krpms.

Allen, please keep up informed about eventual N55 support. Ive been waiting for this for a couple of months. Thanks.

When N55 support is available I will create a new thread. I honestly expected it to be ready to go by now but things have been a little more difficult with DME comms than expected, which is disappointing.

You guys (PTF & Cobb) have done some really good write-ups concerning other aspects of tuning; but none detailing the intricacies of VANOS... Do you guys plan on doing something like that to assist some of the DIY'ers?

The issue with a write up on VANOS is because honestly not every car responds or reacts in the same way to the same changes. Generally speaking the goal with VANOS tuning is to balance it out with everything else: wgdc, timing, boost, etc... are all affected(sometimes hugely) by changing VANOS mapping and it's hard to tell if your efforts are paying off without a dyno. For instance, Sometimes you can run less WGDC to hit the same boost and pick up power(win-win) by a change in VANOS but sometimes you get the jump WGDC and a drop in power(lose-lose.)

We stress the importance of a dyno in this situation because, honestly until you get a very good feel and understanding of it, you can end up chasing your tail and never catch it.

Completely agreed Allen! That's one of the reason I've been hesitant about VANOS tuning... My maps are looking great, just minus VANOS... LOL
Do you know if Cobb will ever allow ATR users to raise/adjust boost ceiling tables? It seems that if a person went out and purchased aftermarket turbos, and or build themselves a single turbo kit; it requires that person to have a PTF tune...

Yes! Cobb has been working on getting that pesky boost ceiling out of the way for a while and it's been working beautifully for us and a couple of the ATR users that have access to beta test it. I can't speak for Cobb but I'm hoping it won't be too much more of a wait for you guys.

Would a custom PTF tune be "safer" to run on our cars (n55 in my case...). When i used to have a civic...I ran a custom tune over the base tunes people had up with Hondata because I heard that it was safer since it was tuned specifically for the car.

I only plan to do FBO on the 135i
