No that doesn't effect low throttle stuff. Only default wastegate duty (until boost goes over 1.5psi), and then the base duty cycle values after that.

Yes I know. It's a double edged sword. :)

It's working at least as well as a single or dual in tank pump. But I still can't tell if its working better as I didn't get a good 100% E85 log on the factory turbos with the in tank pump and I'm...

I'm waiting around to for addl feedback but I may add that min PWM curve scalar to the wheel control menu. Maybe make it user adjustable from 25% to 40%, for example. It's currently set around 32%....

Figured it out years ago when developing the dpfix. Throwing off the rear sensor signal a small amount eventually causes the primary sensor to go off track. Which causes all sorts of headaches as the...

The rear sensors are used to calibrate the primary sensors...

I have not seen much data yet but looking forward to looking at it and helping them tune it up.

I've seen some data on ASR turbos. They look to perform about like RB to me. The real issue with ASR isn't their N54 turbos its everything else with the business including the ownership. :)

I am but I think he changed plans on the hardware. He had a horrible experience with his installer and had to replace his entire motor. Everything left a bad taste in his mouth which is...

Yes hopefully so! If not he should drop the car off with me for a few days. I'd be happy to push the crap out of the turbos for him. :)

Nothing is ever simple when dealing with thousands of cars! But if you are not over boosting down low, etc, then its probably fine.

Normally guys who use e90post are the ones that don't know...

Duty cycle is not really an indication of "safety". It's just a relative measure of vacuum applied to the wastegate actuator. Once you start changing around wastegates, etc, then it's only useful for...

Sensor swap was presuming you're just doing the work yourself. Not practical to pay a mechanic to do it. In that case maybe start by replacing the rear sensors with new ones since you've thrown...

With map 3 we have set a high and a low map and the meth flow (and modifier for octane adaption) moves target between those two maps. With map 6, the additive becomes the boost value that is added on...

The dynojet is the only type of dyno useful for comparing numbers via the internet. It's not always the best dyno to do tuning on but most of us tune on the road and just use the dyno for...

Was done a couple weeks ago. :)

It doesn't really matter...

Sure. You can use meth with any map. But there is no safety or progressive boost mapping unless you are using map 3 (or do up a special map 6). People who run heavy E50 mixtures or race gas don't...

Yeah normally E50 + meth customers would use the "race" flash. But this one only runs meth sometimes. So runs the E85 flash full time. And the only way to do that is with the leaner air/fuel ratios.

SpecialtyZ is considered the gold standard for dynos in this area by the boosted M3 crowd. This is the same dyno both Drew and Sticky use for their testing. They report it reads lower than some other...

It's because dynojets read relatively consistently across the world. I can make a baseline run be anything I want it to be but I can't make a dynojet read higher than normal. Njz is running basically...

I had a customer report 500rw on stock turbos last year. But it was some goofy European dyno. Only dynojets count. :D

It was previously capped at 80% in the JB4 software but more and more customers just want the power output and don't care much about turbo life. It's hard to blame them as the factory turbos are...

If its always bank2 swap front and rear o2 sensors around to see if misfires move to bank1.

With ISO_21 we raised the duty cycle limit up to 86%. Map 7 is a fairly aggressive map and socal weather is always warm and sunny. Great for tans bad for turbo limited cars. On a cold night I'm sure...
