Hey guys. No pics but I do have some info. I told Dad to get plenty of pics today at the track, he used the regular camera
Oh well, I'll get some next time.
I didn't expect much today for the 1st trips down the track although the lowest I can get my wastegate set is 17psi
That's alot for a 98mm but it was all good.
1st pass off the trailer I plugged in the 3100 rpm chip for the 2 step so I left with 0 boost. It went a 2.01 60' with a 6.97 to the 1/8 at 120.55mph. This was at 17psi coming in around 200 feet or so.
For the second pass I put the 3400 chip in the 2 step, left at 5# boost.
60' 1.57 1/8 6.06 123.25 mph.
For some reason I can not review my data log. It's like the info is corrupted or loosing connection on the launch which is not violent. When I return to the pits I cut the switch of yet the computer still shows online when the log is on screen. I have the trigger set at 90 on the TPS and can see when it starts yet the rpm stays around 3000 grand with the map(psia) at 0. Nothing looks right about it. I'll load it on the computer and maybe send them to Cal for review and hints.
3rd and 4th passes were 6.12 at 122+ with low 1.6 60's. Since I could not review any of the runs I pulled 15% out of the timing and richened the map 10% to be safe so it was sluggish out of the hole. After we figure out what's wrong with the data log I'll go after those 5 second slips.
I'm extremely happy for the first day with such a conservative tune-up and running blind. If it wasn't for my confidence in Cal's tune I never would have made a pass.
