I've had this in the planning stages for weeks. I wanted to get some dynotuning done on the Blue Flame after switching to the 4.88 gears and before the racing season started to basically shortcut the tuning time at the track. With the help of a couple MN12 friends, we arranged the date at the same venue we had used last year for the final summer blast event.
My first time actually hands-on 'driving' the car on the dyno was an exhilarating experience, far better than standing idly by. No pics of the car because it was filthy from road spray after towing it across the mountains in WV and MD the evening before through several snow squalls.
The first pull was a 'garbage' pull as the car refused to hold 3rd gear with a locked converter. We then loaded the SCT value file to force the transmission in 3rd with a fully locked converter. I called it the "bucking bronco" tune as it then became quite difficult to put the car in gear without it either stalling or lunging wildly. But the value file did the trick and we were able to get a couple clean pulls for a baseline.
Not bad for a rookie.
(Trying to watch the A/F meter and the tach was harder than it would seem - not really wanting to go over 8K while making sure the A/F didn't go lean. Of course the stock tach ends at 7K and I had to guess somewhere past that when to end the pull. Most of the time it ended up between 7800 and 8000.)
With a baseline of 363 HP, the tuning commenced and soon we started seeing better A/F ratios on the wideband along with some pickup in power.
Once we had it "dialed in", we let the car cool down before the final pull,
or two,
or three... :love-it:
I was pleased, the car pulled good all the way to 8,000 RPMs, felt good and sounded mighty good doing it. All there is to do now is fine tune the shift points and converter lockup at the track.
