tune it via vaf. you'll be good to go

I don't know how to do this. I know how to pop the cover off the VAF and I can figure out which screw to turn and in which direction to achieve lean or rich fuel mix but I don't know how to tell when I'm where I want to be, or even where I want to be.

What's your a/f ratio at idle, cruise, part throttle and wide open? I'm not sure how close you're going to be able to get it, but if I know what you're starting with you can probably tune it within a certain range.

I don't have a wide band so it's really hard to tell. It bellows at WOT instead of making power which is exactly the problem I had before. I don't know if it's blowing black smoke which would help. I think I'll ask the Mrs if she'll follow me on the highway tonight.
It sure makes a lot of noise now between the boost and the bov. Fun to drive though. It is fast, just not quick like my DD.

Best bet then would be to probe your o2 sensor and see if it's still doing it's 0-1v sweep at idle.

That's how you can get away with tuning the VAF tho, o2 sensor voltage shows fuel. closer to 1v = rich, closer to 0 = lean.

My BPT setup goes to .9v at WOT

Turns out it makes great power after 46 hundred rpms.
I'm thinking a few clicks leaner and see if I can't bring that number down some.
If that doesn't work, I'll get out the volt meter.

Subbed for blown engine.

that's not funny
ok, it's a problem. What am I supposed to do?

[Boosted Escort]

buy a wideband. I would go with the a uego. they are only 160 on eBay.

[1st Gen]

I spent my budget already. I'll have to save for a wide band.

sorry man but without the proper tools we're stuck trying to help .. get the WB 02

[1st Gen]

Understood. I'll take care of it.

Rich is a much safer scenario compared to running lean though lol, so at least you can sleep well knowing this.

Just got a question for you about the outlet pipe, was it a 45 degree bend you used off the compressor housing?
