Re: New PB 11.44 @121!!!!!
This was an interesting tune for Sean.. of course all done long distance via logs and BINs.
We had an early fueling issue (bad pump) that cost a lot of time, and then trying to dial in the correct offset for the 60lb'ers took a bit of time but is really what got the injectors to respond in a way that I thought was 'normal'.
This is the first log I've seen of a full 1/4 pass, and of a full 2-step launch for Sean's Ty.
Code59 has a cool 'Spool Up' mode function that I didn't have activated in the BIN that ran 11.44, and in looking at the log it definitely would have helped. He was way rich in building boost, although the timing looked good. I just finished a new BIN with the Spool Up mode activated and we'll see how that works - definitely a cool function that provides a lean spooling mode, and that doesn't affect everyday drive-ability.
This was a first attempt on the track with this tune and I'm happy with it, although I'd say it has a lot left in it... possibly even getting into the very high 10's.
I've always been taught when tuning with meth to tune for optimal AFR's, then add enough meth to lower (richen) the AFR's by .5 to .6. Too much meth takes away power and I think this log shows that in that rpms were 'fluttering', probably indicating us being on the verge of blowing out spark. Sean wanted to run the meth at a setting of 5 on the knob and that's what we did, even though I think its a tad too much for optimal power. But, it certainly keeps the intake temps down and there was zero KR during the entire run
Hard to say how much more his stock bottom-end and tranny can take with power being effectively put to the ground. Sean's converter was stalling at about 3600rpm at launch and I'm surprised that he didn't get a tad more wheelspin (getting it spooled up sooner and launching with higher boost will certainly change that).
All in all, I'm so impressed with Code59. Once you know the ins and outs of it, it's easy to use. The most difficult thing with this tune was logging with both DM and TunerPro so that I could see the AE/PE adders having effect, and dealing with the spring affect of that long intake tract through the A2A.
Sean sure puts a lot of hard, quality work in to his Ty and it's great to see him get this result!
Makes me want to finish my razor kit install and start playing with some higher boost
