Superchips Bluefin

[zei20t]

ahh yes of course, and it would depend on load and throttle position too.

the torque limit you mention before, would a stage 1 map hit that limit? people are doing stage 2 ECU tunes and still not hitting that limit. could be a false positive?

Update so far. Emailed superchips and they immediately sent a new file. This one Is much better, low down now feels responsive with plenty of pull all the way with just a minor flat spot around 3500rpm. The only still worrying thing is now and again when I need plenty of power and put my foot down there is a small shudder like there is not enough fuel to make the power. This is only now and again and mainly in 3rd gear and above. The lack of power is like when you have a bad o2 sensor but it only lasts for a second and then the power comes in. Off to get some data logging done just to make sure the car is ok for my own piece of mind.
More updates to come.
Ps any idea how the bluefin works as a data logger?

did you have your traction control on or off? if on, that would be the traction system interfering (for safety vw says?).

i doubt the bluefin unit can work as a data logger, if yes then i would have used mine often, but i could be wrong

i am on bluefin stage 2 (older file) for almost 2 years / 20,000km now and it has been fine. plus superchips uk does get back pretty quick when you contact them for a new file (during uk daytime).

Yeah it can datalog but I think it may only be on the later versions, have a look under extras. Its not in the manual either - I just checked one.

[Lucas_R]

Is your engine misfiring perhaps? Might need new ignition coils. How many km has your car travelled?

The stock fuel pump on the current Mk6 GTI is more than capable of supplying the fuel you need, so unless the pump has an intermittent problem then that wont be it.

Have you used the Bluefin unit to scan the ECU for any fault codes?

[Reedy]

I've got a max scan Nd no faults found. Just had the car serviced before the bluefin with coils, plugs, fuel filter. The only extras I have on the bluefin are immobilize. It doesn't feel like a misfire just a pause in power. If the traction control in kicking in I think I should see the yellow car flash on the dash. Car is 3 years old. Plus these power losses are mainly in a higher gear moving quickly so wheels shouldn't want to spin???
I'll keep you all posted.

If the new tune from Superchips has made an improvement, I'd try that asking for another revision to see if it makes it even better. Superchips is known to provide good support with regards to tune revisions, but it does make me wonder a little...

Nevertheless, as your setup should be off-the-shelf, if the new revised tune has partially masked a mechanical problem that's not a good approach either.

When logging data, log the following:

* Engine RPM
* Requested Pressure
* Actual Pressure
* Ignition Timing
* Lambda Ratio/Reading

Make sure to hit turbo mode so the sample rate is fast. Then shoot the logs across to someone who can have a read and give you some advice based on it; happy for you to send it to me to have a look.

Thank you mate for the advice. Hopefully getting the logs done today by another forum member who lives close.
I love this forum......

Just done a system readiness test with my max scan and everything passes except 'evap sys' don't know how accurate these things are? Still no fault codes.

Update. Just had some data logs done my new best mate Gavin at Custom Code. Very clever chap and so willing to help. Car runs fine. There were some little glitches with the air flow but all I can do now is show superchips and see what they say. Once again thanks to Gavin for his time, very much appreciated and will get them vag com tweaks later once this issue is sorted out. Cheers.
