I went for a ride the in "Boostmobile" yesterday.... she'* running strong but she'* still in the learning phase. The car sounds awesome! She'* got a a lot of power and when Bill gets her tuned right... watch out!

I brought a lucky horse shoe to The Villa yesterday... hopefully this will be the last motor swap for Bill'* car.

Do you have to restart the car to regain the traction control/ABS? I thought I remember having to do that when I unplugged/plugged in my WSS a while back...

Bill called me around 2:30 and did mention he was getting some KR. Yesterday while driving the most we saw was 2-3 degrees. Today I guess he was getting some more. Oil pressure is fine though. I've been thinking of things that it could be, but there'* quite a few possibilities. I even suspect some false KR from something loose in the engine bay. I do also think his exhaust - maybe downpipe - was hitting against the car/sway bar at one point. I don't know if that has been fixed though. I'm really not sure about the KR issue.

After talking with him, he'* going to take a 5th look for vac leaks and loose heatshields. It may just be a simple fueling/tuning issue.

Ok...

Took a little break from things, did some laundry and a little housekeeping. Things have been waiting for me a while.

Low rpm, typically 3rd-4th where load would be high to the amount of power and once fully warmed up I am seeing ~2 KR. It'* decaying nearly as quick as it comes on. Oil pressure is not going lower than 40 psi at idle and about 60 miles are on the ticker already.

Took a look at all the plugs and found them all to look good. All connectors inside the wires look good. After messing with the rear plugs..I noticed the O2 wires laying on the #4 wire. Was it before I did the plugs I didn't look, went in w/o a light and did the plugs.

Sprayed TB cleaner on all vacuum hoses and they appear to be leak free.

The SC is leaking some oil from the nosedrive to casing area from what I can ascertain. Draining the oil...it'* filthy and appears about half empty. Removed the belt and felt a very slight amount of play from the coupler. Will pick up some oil today and reseal the nosedrive.

At the moment I'm hoping on the O2 wires, the motor was running a little rough. That points to either ignition or the O2 wiring.

Bob.. Yes you need to restart to get the ABS/TC back.

I'm optimistic Bill. I think you have a very nice engine in there this time (that'* not disputable IMO). I'll hope on the O2 wires, and hope you maybe just need to tune at most. I forget....did you say bigger fuel injectors may be needed?
