I have a e6k in my FD and I think I have most every thing set. Well I have the air fuel ratio set a little on the rich side. Normally the car idles about 13.1 and under boost is 11.1-12.1 and the car runs great. Well after I turn off the car and let set for a minute and restart it the air fuel ratio will change to 14.7- 17.1 and runs like *** but when I try again later A/F is back to normal.

 

Sensor going bad?
Bad grounds?
Problems with fuel pressure?

What sensor could it be?
And I am running the stock fuel set up so that can be a problem I will have to hook a pressure gauge. I dont think I could of hooked the fuel relay wrong.

 

what do your correction maps look like? have you gone over them to make sure your engine starts up right when cold/warm/hot??

You might also wanna have a look at the post start map and check the setup on the Fuel Setup window.

As well as going over the things RETed said. Go online with the software and check to see (before you start it and runs off) where your sensor temps are, if one of them is showing -40 degress its not connected right or the pins have come loose, and that would cause all manner of problems if your correction maps have been dialed in.

 

Um, how are you monitoring AFR's?
Wideband sensor going bad?


-Ted

 

Well I have the Turdo XS wideband w/VW O2 sensor. I would think it is going bad. Well when the car is running smooth the AFR is in the 13 and when its rough it in the 14

 

Claudio well I got it narrowed down to doing it when it hot 180 or higher. Well all the senor are all working.

I also have the Post start temp set at 127 below

Correction maps ? Are you refurring to the Barometric Correction. Well im using "method 2" and the map is zeroed out.

 

Sounds like the water temp correction map is wrong...
