I can't believe I din't search harder for that damn data link to the laptop before. After installing an Innovate XD-16 kit w/LM-1 way back this spring I "put the box away somewhere safe". I found it in my fricken bookcase a week ago. I tried out datalogging my AFR for the first time tonight. Wotta hoot. Very easy to link, to initiate and stop! I can't wait to try this at the strip. I liked the guage alone earlier as I could read it in 3rd at WOT. But I've pretty much always done it the hard way and for someone who has tried reading plugs and changing jets/ doing a pass/changing jets/doing a pass etc this is a quantum leap forward. I had a poor showing a week ago in Drayton due to an off idle stumble and idle problem. First I found the secondary blade position out by a mile. Anyone else ever have that little underneath adjusting screw for the secondaries back out a bit? Resetting the blade properly solved the idle problem. I am sure I had been compensating for the poor idle with the pump shot and then revving it to about 1100 on the line lock.. Back to the laptop I did a few of idle blasts on the street tonight with the idle working, had a stumble both times and can see it clearly and easily in the form of lean 18 : 1 spike and recovery. With the datalogger I can now see my pump shot in the mix clearly and I can adjust according. I coulda run this thing months ago if I knew it was so easy. Time to do a free air calibration and then strap this in the car at the wedensday night drags!
