Default L27/67 hybrid testing officially started

Don was gracious enough to loan me his scantool so I could get some good hard numbers on what exactly is going on with the car now. First, allow me to recap my findings prior to my move (March timeframe):

20* KR...about the maximum retard I think. Aside from the L27 core, nothing else was changed.

So I move into the house, and Jinx moves into the garage. First to go is the cat, replaced with a magnaflow unit. Then, of course, the transmission. So for a while before the transmission, and just shortly after, I was chasing down a good solid reason why I was running pig rich. My spark plugs (Autolite 605s) looked good with the exception of a reddish hue...Don and myself can't figure that one out. Anyway, I go to A606s, and I find out #5 spark plug wire was just chillin'...as in not properly crimped. So THAT got fixed today too. As well as insulating my rice pipe and permanently installing the IAT in the tube.

On to more testing...we first verified all the gears in the transmission was working, as well as TCC. All good on that front, so on to other important numbers. After fixing my plugs and wire issues, my rich problems went away But the best numbers of them all....my 20* of KR went down to 5*...and that is only during shift.

So far, so good

Yes the car runs much better, and its nice to drive it as it actually put the power to the ground instead of freewheeling...LOL...

Fires right up at the flick of a key

Of course I had to give the throttle a couple of Jabs just to hear the M62 and see the boost gage point towards the southeast

also 3rd gear TCC and 4th with TCC come in on the money... Nice and tight with no slip

You shouldn't be running with 5 degrees...that'* way too high. Did you put a smaller pulley on?

No...running the factory pulley. But I AM running 3 & 1/2 month old gas, and the IAT was about 100* at cruise. Remember that I said the KR only occurs right before shifting...but my question is how much is it supposed to pull? I still have some work to do on isolating the intake air too
