Hey guys, 

 

Drove the car last night on a long straight on: R|C|N pressed hard from 1-5th shifting just at 7k rpms. When i turned back, on 2nd and pressed the pedal fully, the engine lost power the car wasn't accelerating hard and won't go over 4k rpm.

 

I have the COBB accessport, no CEL or limp mode came up. put the car on Park, tried again and it was back to normal. I thought it could be that the traction was on causing this so did the same run again on R|C|off, all was good. 

 

Later, it happened again. Parked and it was back to normal.  In the video, i had the pedals fully pressed.  What's the issue??

 

see signature for parts i have

boost leak maybe? not bad enough to affect the car at idle, but once you hit boost, it bleeds off all the pressure?

I've been on this setup for almost 2 years now. This is the first time it happens... no installs have been done since.

You need to log the Safety trip to see if that is what it is.  Cobb has a Safety feature that will do as you describe if anything exceed the safety levels set by tuner.  It will pull power to protect the engine.

You're tripping STFT safety (see https://cobbtuning.a...t/view/78610496 for other safety codes).

I had a similar issue and it was a secondary pump failure


Yep, either a pump is on its way out, or the post-filter finally got plugged up.

Either way, I see a Visconti fuel basket in your future. ;)

Hi, thanks thats very helpful. Could you please educate me more.. lol  I currently have 1100cc ASNU injectors and ASNU 330lph pumps... which pumps are you talking about? 

 

I might be going for service this weekend, is it an oem part replacement or.. what do I need? Thanks !

 

note: I haven't used e85 for over a year now. I've had the injectors/pumps for almost 2yrs now.
