yeah, that's weird man, i've never had a problem like that with my plx. i would imagine that your actual sensor is going bad if it's giving off wack readings like that. you can replace the o2 sensor itself for about 35 bucks.

if you have the sensor any closer than like 18-24" from the turbo, it causes premature failure from the heat, you prolly just need a new sensor....oh and nice car and welcome to HMT!

The sensor is a bosch and its only has like 3000 miles on it if that, I replaced my factory with this one that came in the plx kit. I dunno, seems to be working fine now but I dunno. Do you all think that is a pretty good curve on the dyno sheet and is there room for much improvement. I would really like to stay with 0bd0 if all possible, what are my options.

Looks like fun!

400+whp in an EF = the most fun evar!

Yeah, your afr's were scaring me

I hope that the sensor is failing... man, I would have cut the gas as soon as I saw 13+ while in boost. You are a brave man.

my plx never ***** up. if i were you id look into turboedit if you want to stay odb0 the fmu and other youre using arent good. do your motor a huge favor a use turboedit

yeah, i know it's a bosch wideband sensor, but sometimes they go bad, especially if your car is running rich, how's your a/f ratio while cruising? that could kill it if it's rich at part throttle, but more than likely not in 3k miles like you state. your a/f ratio looks good in boost, a hair lean near red line, but with a program like turbo edit, you can tune your ignition timing and pull more power, also, from what i saw in the video's, it would drive MUCH smooter as well and have a much better transition in to boost. i could see it was breaking up a lot in lower boost, you could get the car to drive pretty much like stock.

What do you think is better turboedit or should I go through the steps and go uberdata, which is better. I would love to go turboedit, just not sure how to go about getting it. From what I understood on previous research, I would have to use a pm6, I couldn't use my pr3. If you or anyone else could give me a brief on what I need and what needs to be done I would glady get into it. Any help would be much appreciated. Thanx

finally a noob whose willing to learn and ditch the fmu for a solid management. props to oyu and your car

obd1 conversion harness + p28 + ostrich + crome is what I would do. You could make a shitload more power.
