fuel mileage is back on par with the stock tune. no fuel smell in the exhaust. it's running smooth better than stock. hundreds run ms with narrowband and have no problems. i'll throw a log on here after i leave work today to see if y'all see anything. it's my only option right now cause i have to get to work (shirt drive with low speed limits).

Maybe he's extraordinarily experienced with these.

The only time I've ever seen stand-alone megasquirt without a wideband was at a race car shop that was very experienced with tuning. Once they had a car completely tuned on the dyno they would remove the oxygen sensor and controller for the actual races.
Can't afford a $150 wideband but must have a turbo, lol. Must have a spare engine and lots of free time.

i ordered the mkturbo kit so i have a wideband but i can't install it because the exhaust doesn't have a bung on it. the way my factory o2 is installed i have to keep it as is until i put the turbo stuff onto the car. it's currently metal clamped and exhaust sealed into a hole that i couldn't tap because the metal is harder than the tap that i have, and it's a cheap ebay turbo i got awhile ago. the bung is too far from the factory o2, and the bung directly faces the transmission so even if i were to try to install it it would not work. as it stands i'm running the base tune with the tweaks suggested until friday afternoon when i get off of work, and then i'm going to remove all of the na stuff from the car, install all the turbo stuff (including the exhaust with a properly placed 02 bung and the wideband) and go from there. i figured out what my initial problem was like i stated in the "pig rich" post and have everything i need to make it right after i go on leave from work on friday.
please bro.

yeah, it got messy and stupid so i fixed it the best i could until the good parts go on. i just got back from deployment like 3 weeks ago and i go on leave starting friday so there's been a lot going on with the parts ive been putting on the car plus a bunch of other stuff. i have 3 weeks to iron out any kinks i encounter though so i'll be fine.

hey guys. i don't know why but my car cuts off after driving it for more than a few minutes or so. i dropped off my son at school (about a 7 minute drive) and after accelerating and cruising and all of that i cam to a red light, clutch in, and the car just died. same happened on the way home. can i post a log and tune here to see if y'all catch anything?

good morning! so i got my car pretty squared away as far as running and driving is concerned but i still need to rope in my idle. with the help of some very good friends i was able to keep it from oscillating between 1500 and 200 rpm. now it's kind of lightly bouncing between 950 and 1100. can y'all see any changes i need to make from my log and tune to get it to settle down around ~900 like it ought to be? i appreciate the help guys.
edit: i'm going to run another shorter log and attach it. i exceeded the limit by like .48kb
