Spent two days trying to figure out what was up with the car. I drove around causing it to misfire while datalogging, the car was running super rich, in one bank, super lean in the other. Swapped out the injectors for 21lbers and it ran so lean that I was afraid I'd blow the motor. Checked for vac leaks, found a tiny one on the fuel pressure regulator. Still no cigar! GRRR! What to do what to do. Took it out again and it began misfiring even at idle.

This was a good thing, now I could narrow it down to one cylinder. Swapped coil packs between two and it was still misfiring on the original cylinder. Now I'm feeling REAL stupid for not checking this in the first place... Swapped out the spark plugs and what do ya know, the misfire switched cylinders. 30 bucks later and the car was running perfectly!!

Here are some videos of me having some fun in the car:


Here is a video of when it was running OK with the old spark plugs.

Did another couple pulls with the M3, and took it to the strip yesterday.

The car only pulls on the M3 up above 6k RPM, and I only ran a 14.6 at the track with a good launch and semi quick shifts..

This leads me to believe that Active Autowerkes tuned my car for cams, since it is still throwing a CEL for running way too rich, and because they only offer a 24lb/hr tune for a car equipped with cams.. The car never goes into closed loop mode at WOT(drops O2 sensors out of the equation) either. So I don't think it's making full power just yet.

I will be ordering some Schrick cams in a couple of weeks, I will call up AA and see what kinda tune they actually put on the car too.

Any way, that's all folks!

Aktiv Autowerke OBD2 tunes have issues when tuned for bigger injectors. I would stay with stock injectors and cams.

Thanks for the reply! I replaced one o2 sensor and now the car pulls way harder and spins in 2nd easily. Still has CEL and now is throwing a pending code for the other one, so hopefully that'll fix the issue.

The car has been running very well. I've put a little over 2800 miles of pure, red-line hitting, Texas 100+ degree weather, running AC full blast, and it still hasn't fallen apart! The car see's it's rev-limiter at least 5 times a day, every day, and on days where I purposely take it out for the purpose of ripping on it, it has no trouble bouncing off the revlimiter and burning the tires in 2nd gear all day long.

I also made a bunch of videos and posted them on my YT channel. http://www.youtube.com/user/TurboGLI2004?feature=guide

I recently blew out both rear tires at the same time and spun out on a pretty narrow road. Luckily I avoided any contact with the curbs! If you look at the channel, be sure to check the videos titled: "332ti tire rapeage", "332ti with 205 tires", and "332ti with 205s vs 95 M3" They show a pretty good idea of what the torque of the 6 cylinder can do!

I have begun thinking of installing a custom differential oil cooler, since the LSD sometimes gets to temps so hot that it will singe the skin off of any fingers that might come into contact with it. I am hesitant to really dump much more money into the car after I install the cams though, since this is my daily, and I have begun planning out the funding and design of my next car, which will be a fully stripped 914 with an NA built LSx motor. The ti has caused me to become addicted to light weight and high power output. So 450whp in a 2000lb car should hopefully satisfy my needs!
