It's a very tight track that rewards good lines vs outright horsepower so lots of fun.

Thanks heaps, I wonder how they correlate with the N54 fault codes?

Okay so it's one with curves, but lots of fun none the less.

Yes mate that will work fine.

That would be appreciated.

I have that info, what I want to know is where to look i.e. what part is suffering the signal interruption. They are not listed in the Bentley manual either.
Only got these codes after BMW...

Did this ever get posted? I got a bunch of codes that I cannot work out, 2FCA, 2FDB, 2FDA. Does not seam to affect drivability but I'd like to know what they are meaning.

No flaw in the theory, and I've never said that without CPS offsetting you'd blow an engine in a certain amount of time.

Not sure how you got to this assumption.

An N54 has failed, what exactly we don't know.
The vehicle was using a JB4.

So if I'm right your thinking that I was asked to start the thread, if that's your assumption your wrong. Id be more than happy to try your product once it offers CPS, I promise a fair review (no...

Sticky sure it's very advanced & BMW would have engineered it's timing tables to cope with 20PSI of boost no worries every day of the week :)

If it was engineered from the factory to cope with 15...

Figured as much, all fun in love and war :)

Sticky a factory DME calibrated to adjust timing is going to do a perfect job when boost is doubled? The DME would of course never see that as it would throw a code and limp so really a mute point on...

Once the OP gets the proper diagnosis I'll happily update it. At the moment it makes most sense to leave as it is.

I've never said JB tunes are proactive in respect to timing adjustments. This is simply impossible as they don't have the hardware needed.

I was illustrating a point that the majority of users may...

The point I'm making is that by being proactive it will help the engine last in a higher % of times / cases of something going tits up.

Proactive is nearly always better than reactive.

As for...

Terry this is misleading, you don't "instantly drop timing". You tell the DME it's over shooting boost / fuel or whatever and it drops timing etc, by what amount is determined by the ECU not the JB...

Terry if every one agreed both systems retard timing then this age old discussion would be mute.

Procede retards and advances timing via CPS signal adjustment which results in the ECU advancing /...

That is how I understand the procede works but you've forgotten one aspect.

By the very fact that the piggy can have the ECU reduce / increase timing by means of a CPS signal adjustment back to...

Why is it dumb?

Sticky,

Honestly nothing fed, I initiated the thread as your site had no info about it..... maybe I should ask for a commission for the extra traffic :)

People jump on Shiv's responses on e90,...

Doesn't really seam the tuner really knows what he was doing IMHO.

Increased boost and fuel generally needs timing to be changed as well. Flash tunes do it, factory remaps do it but JB3/4 relies...

OP on e90 just indicated initial dealer diagnosis is bad turbos..... but they are still checking.

Links to the 2 threads are below, would be good if we can get some information here that does not descend into a tuning war.
