So my car is running a little rich all of the sudden on e85. I was going to try and get a log for my tuner. I want to first say, i am still major newb with evoscan and ecuflash. I tried to log everything that it would let me, then deleted the columns with no values so it wasn't so cluttered on the spreadsheet. Anyways, going to send it to my tuner but wanted to also post it here to see if you guys saw anything that popped out.

Boost was 28 pounds and AFRs are hitting 10.8 then staying steady at 11.0 till redline.

Hopefully i uploaded it correctly?

Car is a Evo 9 with FP red and bolt ons. Running rich after new Tial BOV and new intake. Had it tuned on speed density 3 weeks ago. Been having IACV issues as well (or so i think)

 

So was it not tuned with the bov and intake that are on it?

I could see going atmospheric from diverter causing a rich condition off throttle, but that's not the case here. Intake more restrictive than the last?

 

Thats correct. I'm having the tune adjusted next week at no charge. The Intake that it was tuned with was a 4" Intake. I needed one with a pcv bung on it so I sold the 4" and got the ets 3" Intake. So it is more restrictive however much that 1" would be.

 

Ahhh, cool. I bet the retune will straighten it up. I'd put money on that intake causing the rich condition.

 

I can see the intake being the issue also. I had a similar problem.
