It's stalling before the car has warmed up? How's your AFR? pig rich, lean? Does your idle surge?

REad the diyautotune writeups on tuning, that should get you started. read the threads on here about tuning. autotune is something the n00bs latch onto and regurgitate here as if it "automatically tunes your whole ecu". It doesn't. it's just a cool little program to help you dial in a rough fuel table.

you need to calibrate all your sensors. you need to make sure wideband communicates w/ ms and they match. you need to do the idle valve test. then tune idle ve and closed loop idle settings. THEN you start autotuning

^I calibrated my sensors & re-checked timing. Now it just sounds like it's running on 3 cylinders. I give up. I'm so confused still even after reading almost all day. I'm going to see if I can get a local to come help me out.

This is how I feel about my project at this point. I shouldn't be allowed to touch my car anymore.

It's a steep curve, don't let anyone tell you it's not. The bottom line is: do you want to spend hours/days/weeks/months reading and learning and then hours/days/weeks applying the knowledge, observing the results, learning from them, and making corrections as needed

or

Find a competent tuner, drop the car off with him, pay him his rate, and pick it up done?

It's just better/easier knowing your expensive **** is in good hands. I went through the same thing with my old RSTi & my WRX. I could never get either of them tuned. Both always had some small problem that wouldn't let me simply put a tune on them. Sometimes, it's just easier having somebody (who knows their ****) make your ****, not as shitty.

Well....now I feel like a dumbass. Apparently, launch control was on. I have no idea why but once I turned it off & power cycled, it runs perfect now. I drove it around for a while letting TS autotune & that also helped quite a bit with the idle.

I didn't think folks autotuned idle. Maybe the idle smoothed out after warming up which would point to warm up enrichment?

It doesn't but that may be why. I still need to adjust the idle a hair as it surges a bit.
