Durametric logging virgin!
Mark,
Thank you for your comments, but with out knowing how the file programmed... Im not sure your comments are accurate.
Also, if you calculate injector duty properly with ALL known inputs i don't see more then 87%. Im assuming you are using the ( Injector Pulse Width * RPM ) / 1200 ....which is an estimate at best.
Bo - I received your email.. Ill be responding shortly!

your car as it stands is far from healthy... not blaming any particular part on the car... but you need to find the problem... so adding race gas is a quick look into whats going on.. IDK you set up but ur also running 94% injector duty cycle at peak TQ... the lambdas are way too low and it is due to knock... too much boost low octane poor cooling= a ****tail for some trouble...
You will probably see notable gains with a 50/50 mix but for troubleshooting purposes, the closer to 100% race gas the more black & white the answer will be. 100 octane (R+M)/2 method is fine.
Here is your timing vs an old log I have. I was running a little more boost on a hotter day but is an example of the trend you would see if you are octane limited and added race gas. Mine isn't perfect by any means but decent and on the conservstive side. A few bobbles in there but the swings aren't as drastic.
Another can o' worms to consider: Last time I checked, Tony is a big fan of water/meth injection with good failsafes like the Aquamist HFS-3 and HFS-6 systems. This would improve both knock resistance and IATs if 24/7 race gas isn't a viable option. Thread for more info: https://www.6speedonline.com/forums/...-complete.html

OK, getting ready to add some 100 to a relatively empty fuel tank and run new logs. Just one question/concern: Are there any issues with running 99-100 octane on a flash programmed for 91?

If you have not done anything with your car since the original logs then some 100 octane would be good to help see what your system is wanting.
So in short.
NO!!!! 100 pump is in no way going to hurt anything.

100 Octane Logs
OK guys - here are 4th and 3rd gear pulls with 100 pure octane (99 at worst since I ran it almost dry). Looks like my lambdas came up a bit, so, judging from previous posts by the experts, that is a good thing. Tony, I would love to hear from you too, as I got no email from you as promised.

I will fwd you the email tomorrow. Im 100% sure i sent it letting you know there was a new file on the server available for flashing.
Please flash and relog on 91... I will gladly take a look. As for these logs, they look very good. IAT creeps away on the 4th gear pull, Im assuming stock IC's?
