Turn off the o2 sensor and run it open loop. No fuel trims anymore... Your big MAF is going to make the car more inconsistant and have bigger swings than a stock sized MAF car with stock injectors.

I am on the stock intake/MAF though right now. So in theory it should run fine correct? Assuming injectors are decent and not piles of crap?
Maybe I could just run open loop instead...hmmm, who knows. I am about 2 steps from ordering the 2150's and being done with it and just running open loop. I have talked with several people and on E85 people seem to get the 2150's to work perfectly fine.
Is anyone running 2150's on the stock X ecu successfully yet? I thought about putting them in my car but didn't wanna mess with them at the time...I'm sure someone has done it by now (and hopefully shared their results).

Yea, plenty of people. On pump gas they aren't really recommended. But I just spoke with Golden and he has tuned two on E85 on the 2150's and he said they idle fine at like 800rpms and drive perfect.
You don't have your stock injectors do you by chance?
Shawn has some too, so if I do end up needing them I will PM you
Thanks a ton for the offer though, much appreciated.
I am going to stop at MAP here shortly and put the car on the lift there over my lunch break.
From the logs it looks like an exhaust leak or possibly a boost leak. So I will see if we see an exhaust leak or try and do a quick boost leak test.
hopefully we find something. My scalings for the injectors are currently overly rich by quite a bit, down to 636 and at cruise the car is still adding fuel, so it would seem there is a leak.
I usually run the 2150s in open loop, because the "small" swings that factory ECUs do around stoich during closed loop are huge swings with the 2150s. They tune amazing with standalones, you have to put up with some quirks on stock ECUs, since stock ECUs often don't work the best at very low pulse widths.

Nope I do not. Would love to see what all he did to get them to run nicely, as I'm sure there's some tweaks that are needed (esp per shane below)

I wonder if there's a way to narrow that 'sweep' that's made during closed loop....I'll talk to tephra & mrfred.

If you want, PM me and I can give you his email if you want to ask him a few things. I am not sure of all the details, but he didn't seem to have a problem dialing them in. I assume open loop for sure.
Or you can try a PM on EvoM or Evoxforums, name is Golden.
that with my tint and its a no peep show venue. LOL @ heater.
