Superchips Bluefin

No worries, any time. Forgot about the needle sweep stuff etc.

sounds 'a little' similar to my situation

put a bluefin stage 1 tune onto my MKV GTI and after about 2.5-5k km the following symptoms suddenly happened:

- revs continue to climb/jump rather than dropping when engaging clutch to change gears
- cruise control doesnt work
- surges up to around 3000rpm
- very rough & jerky through the rev change and gear changes

Problem is even after returning to stock, all symptoms still exist. Have had clutch switch & throttle body replaced which did not fix the issue.

Contacted Bluefin who said since the problem still exists after returning to stock, they don't believe it is tune related.

Currently testing the ECU for a possible ECU issue which I hope it is not :s

Oh dear, so sorry, I feel for you.

Quick update. Sent Superchips the logs and they immediatly sent a new tune back with the explanation that they had altered the tune but the lambda sesor readings were a little off, maybe this is why i am getting the flat spot sometimes. Anyway, drove to work today and so far so good but they say they may have only masked the problem and it may come back as the part deteriates more. Just think i am going to stick a new O2 sensor on anyway just for safe measures.

I'll you all up dated if things change.

I'd be thinking its not tune related too and being a mkV there are a few other components that may need looking at eg MAF or diverter valve. Is it running the stock intake still ?

That would be unusual for a 2010 I would think

Change of plan, going to first get the MAF sensor and O2 sensors checked first before I replace them, they are quite expensive. Not enjoying this experience at all so far.

[Reedy]

Update. Just had the car checked over by the Snap on Diagnostic tool and there is no reading from the O2 sensor after ther cat. Bank 1 sensor 2. Does anybody know if this may cause flat spot issues? He is having the car tomorrow to run full checks when it is in stock.

Thanks Reedy and likewise, hope you get yours up and running perfectly soon as well!
