Re: Idling issues after driving and flash of ecu
We're still working out some bugs with the new hosting provider. It looks like there is an issue with attachments.

I can email the logs and pictures?

Just give them a day or two, this is just a permissions issue and can be fixed really quick.

In the mean time I'll keep playing with the tune

Re: Idling issues after driving and flash of ecu
Your MAF cal is light years off!
The minimum LTFT's I've seen were 10.94 Ithink, and you have LTFT's even of 20+ !
You need to get that addressed last week, scale your entire MAF cal with like 12-13% up and then start from there (your trims may vary in the -3% - + 7% range but that's way better) , right you the ECU is adding a lot of fuel for the air it actually sees compared to what's in the MAF tables. And I think that past 20% it will not add or learn anything and may result into the behaviour you've seen.
I'm not sure that chopping that CAI did this, even though you don't have an air straightener while right now your air filter is significantly closer to the MAF you should still be ok, or at least not get the behaviour you described and be able to drive your car properly.

Re: Idling issues after driving and flash of ecu
Be sure that your VTA BoV is not leaking.
Re: Idling issues after driving and flash of ecu
Right, it seems to spit out a lot of oil, not sure if there's any left in it to lube the piston

Re: Idling issues after driving and flash of ecu
Ok,
So I've did +10% on those values... it runs even worse..
So I removed and did +5%... doesn't run so good...
In to the process of shitting myself due to the Tactrix adapter being a piece of shit and timing out during 3 attempts at flashing and recovering....
The oil... most likely a left over mess from me forgetting to put the oil cap back on before starting the car..... oops.... lots of degreaser
If the BOV was leaking wouldn't that normally leak under pressure/boost. and when it is idling is would be under vaccum and be more likely to cause it to become lean instead of rich??
Out of left field I thought I might ask... is it possible my fuel pump isn't bleeding enough pressure off quick enough hence why its super rich?
