Sadly, I don't have closed loop anymore. Dyno Brian locked my long terms at 0. According to my notes, I have NGK BR7EF plugs gapped to 0.020". Sounds like I'm a bit tight for 10 psi. lol I'll do some more playing tonight since I'm motivated now.

I have closed loop, just using STFT's during that time with 0 LTFT, so it still adjusts moderately for normal driving and indicates any issues with big numbers. I'd guess Brian did something similar, dunno.

I'm running NGK 8's with decent success so far, but was always on AL103's and AR103's with similar gap. 20 seems like a gap for a guy running 30+ or spraying the house down. You should gain some mpg's opening that, too.

Ahh okay. Yes, I do have closed loop then because I have changing short terms. I just don't know when it transitions from open to closed. is that something I can monitor in HP?

My MPGs SUCK. I went a week of driving back and forth to work (mostly highway with 55mph limits) without really getting on it last year and calculated something despicable like 18 MPG, so that alone is motivation to pull the plugs and open them up a bit.

Brian made me run to the store to grab those NGKs and gap them to 0.020" because he doesn't like Autolites and I was getting pretty bad blowout right from the start. However, that gap suggestion was made before we knew I would be limited to 10 psi due to weak valve springs. I'm sure it would do fine with a bigger gap.

I went to Napa after work yesterday to grab a new crank sensor. My cam sensor is supposed to come in today, but whatever. My current one looks gross but appears to work fine. Anyway, I replaced the crank sensor, started it up, and it ran way worse. :poop: So I almost guarantee that my harness works just well as it looks. I was pretty bummed about that because I haven't been doing too well with wiring projects lately, and fixing a 19 year old harness is rarely sustainable.

When I started doing preliminary research on pigtails and repairs I found Dorman 645-688. I had no idea that this entire section was detachable from the main harness! Thanks GM! Suddenly, this fix is not very daunting at all, and I should be on the road tomorrow! We'll see.

The part stores have it wrong. This section of harness is not the same on F-bodies. It is all part of the main harness which makes repairs a bit more involved.

I did find something though. This is the power wire for both the cam and crank sensors.

After some cutting, soldering, shrink tubing, and re-looming I had brand new pig tails installed for the crank and cam sensors.

This didn't fix the car either. Since that exposed part sat right next to the block without loom, I thought for sure it would run great. All hope is not lost though. The car runs differently from before. It's just not good. I'm not sure what to do next. I'm thinking about making a couple chains of zip ties that wrap around the ICM harness and a couple other spots so that I can wiggle them while the engine is running. If it freaks out, I'll know that it's time to pull this whole harness out.

I figured it out!!!

After the last test drive my front crank seal started puking oil, so I replaced it. That's when I finally found out why the balancer felt so sloppy.

It appears that I drove the balancer home in a hurry not realizing that it wasn't engaged with the key. This would basically bring everything in the ECM out of time without a CEL. I removed a good key from my spare engine, let's hope I can pop this damaged one out just as easily. I have another timing gear on deck too if necessary

After stripping the front of the engine down again, I got to deal with extracting the stuck timing gear. It wasn't as bad as thought it would be though.

Yep! That's not right.

New on top and old on bottom.

The air hammer with a pointed attachment did good work on the flattened key. Reassembly is now as easy as tapping the new key into place, and reinstalling everything else as designed. I decided to stop here for the night though. I'm not too scared of reusing the gasket but I'm out of coolant. Half of it spilled onto the floor and into the oil pan so I'll need to do another oil change too. Let's hope this thing finally runs flawlessly tonight.

I got the car back together and went for what I consider to be the first REAL drive with the TKX. Part of me is incredibly excited because I kicked the 275s sideways around a few corners and paid no regard to third gear's well being. :cool: The other part of me is bummed that I can't "just enjoy it" as I planned.

That smoke will be a relatively easy fix. My oil feed fitting is leaking for some reason and doesn't want to stay tight. I may need to switch to a flange style fitting instead of the NPT to AN adapter I'm using now.

While I'm able to drive the car around town and even give it some light beans without issue, it won't tolerate full throttle. It still breaks up in boost and high rpm. One time it was even bad enough to back fire through the turbo and blow off my inlet tube. I think it's time to start the diagnostic process all over again. I have a fresh set of plugs I can throw in. I might have to try a spare ICM swap and coils after that. Fun times.

FIXED! The car needed plugs. I also opened the gap up to .030" in hopes that they'll last longer. I won't be pushing enough boost to warrant .020" for a long time. This car is such an animal with the LS6 springs. It revs with 0 complaints now, and I can power shift this sucker with 0 regard for a T5s life. :D

I got married on the 13th. The night before I decided to grow a pair and celebrate with a bit of smoke. The results were pretty spectacular! Thanks, line lock. :cool:


Those are some pretty damn nice lines for an open diff!
