BOV instead of DV
« on: August 16, 2012, 12:04:35 PM »
Hello!
One more question: What maps are involved in swiching over to BOV? Right now I see only P1297 error class zeroing... Maybe someone already did this?

1) What problem are you trying to solve by using a BOV?
2) What do you plan to do about fuel trim problems?

It's not really a problem but when I have put my brand new IC I didn't have enough silicon hose to connect it all the way to intake. Now passage to dv is crammed as.... Right now I let DV to vent to atmo instead of intake (same as BOV but quiet). There should be a way to ignore coming back air.... If anyone knows please speak

You mean there should be a way to calculate the amount of air that suddenly went missing?
Not gonna happen.

I mean to edit the functions so ecu wouldn't think that there should be returning air in the first place and take fresh batch of air through filter

Read what you typed, read it again, then think about what you said.
