Alright just a quick question for you guys. I'm about ready to start fabing up hard ic pipes and I was wondering if I have to switch to an sd or gm maf in order to vent the bov to the atmosphere rather than running a return. Hope that makes some sense. /ubbthreads/images/graemlins/dunno.gifI'm sure its been asked before but I search and didn't find much.

yes. you need the gm maf or a SD set up where it takes the readings after the BOV, if it isn't after the BOV you will have problems and the car will run like sh*t.

Much appriciated. I guess its time to go spend more money.

I have this issue now. BOV leaks at idle and low fuel trim is around 76% and o2 trim still shows rich.

there is code around the inter web that checks tb opining so it doesn't add extra fuel when bov is venting.

What sd set up is everybody running. Im looking at a compete set up from buschur racing. click anyone using this?

Same kit is cheaper from JNZ Tuning. Much better guys to deal with as well. You can thank me later

Edit: Your car does have ECMlink already, correct?

You're running ecm?

Ecmlink is in the mail should be here this week

If anyone Is interested this is the code I mentioned above. The code now works with the E931 Rom for DSM's after recently being ported over from EDM evo III software. The original author is from the UK. His presentation of it can be found in it's entirety here: click
