Great run man! What fuel mix were you using? I want to run map 7 instead of map 5 now! 100% e85 should do the 100 octane minimum.
Just switched to Map 7 recently and the car feels STRONG. much more so than map 5. What were the conditions of your run? What RPM do you launch at?

I was running 2:1 e85 / 100 octane. I had to launch at 2.5 cuz anything higher would give wheelspin then trans would shut off. I tried 100% e85 and got fuel code error and cylinder shut off. |

Congrats on the times! What rpm did you launch at for 6MT?

How much faster was the car with 2:1 e85/100 octane vs E85/93? launch would cause wheelspin and trans to shutoff? really? 1.8 60'? I cut 1.7 and no problems with mine i guess. shifting at 5500.

I have all season street tires so they aren't exactly the best for drag racing. I think summers or DR would be needed for better launches. I think 1.5 would be very possible. I try to shift at 6.2k or so |

Also, mykal335xi, I look up to you and tried to read all your posts to learn about xi stuff. My experience is that wheelspin induces trans shutting off. This doesn't matter where the RPM happens to be. In addition, I don't know how you were doing 2nd gear lanuches. Maybe better tires? Thanks, Kenny |

Maybe wait for some rain and play around with launching in the wet, that's always good for a healthy amount of spin, especially if it's a new road/parking lot that is smooth. The 2nd gear launches I haven't done in a long time, it blew the 2nd gear from my trans and I had to put in a rebuilt one. I probably did 75 launches before it started going out, but for me it's 1st gear from here on out as 2nd gear was only a tenth faster. |

I haven't experienced bad wheelspin yet, one day My car was pulling like crazy today with 60% e85 mix, i was seeing 19-20 psi and 12-13 degrees of timing. Do you have the logs of your runs??

The next time I run I will be doing custom backend flash and map 6. I don't have logs of the run but I do have logs of the two fuel mixes: 2:1 e85/100 http://datazap.me/u/knissel/4-gal-e8...ctane-3rd-gear 1:1 http://datazap.me/u/knissel/2-3-4-50...bms-race-flash |

Really. 100% E85 you got fuel code error. do you run JB Flex Fuel sensor? How does the 100 octane work for you compared to e85/93?

These maps are fantastic, i was messing around with the parameters on the bottom, how did you upload them? Export them from the BMS software? You seem to be averaging 11 degrees of timing in boost in 3rd gear, and 17 psi! that's fantastic, turbos are healthy. IAT was low on the first map, was it cold outside? second map it was closer to 125 degrees. Map 6 is custom right? Trying to hit more boost?

This is all subjective just saying my butt feels happy. It was hotter out with that IAT and also I did 4 logs right before that one. |

So e60 feels stronger on map 5 than map 6? What about map 7? Shouldn't that be 18.5 psi target? my car was hitting 20 psi on map 7.

You should be able to do much better than 12.7... 6MT or 6AT? What's your 60 foot ET? You have DPs and FMIC, but I guess you are running 91 octane gas (looks like you're from Quebec City, and I know there is no Petro-Canada 94 is Quebec City area). What's your tune? What map are you running? You should be able to run low 12 seconds with proper tune/gas and a good launch...

Ran last night on a hot and humid day at Englishtown. Best time of 13.4 @ 112 (will edit post with specifics when I get home from the office). Only modification is the Procede 2.5 on the 5-23 maps (Map setting 1). Car weighed 3855 with me, boxes of sample silk wedding invitation boxes and gas tank on 8 miles to empty LOL. Ran straight from the office...suit, tie and wingtips...full street mode.
