Here is the sneaky spot i put my bottle.
Here is the sneaky spot i put my bottle.
Here is another log. I was into the boost alot more this time through most of the speed ranges.no cops. lol
I noticed there was ons spot where i was off the throttle and the gauge maxed out on lean, I got into the throttle quickly to bring it down.
It sounds gnarly into the boost but extremely loud when passing as the wastegate is vented to open air.This will probly be my last log for about 15 days, I gave my dad the flash scan for his duramax. he is goig on a 700 mile trip for work and towing a trailer, so if he had any complications he could work them out...
You forgot to attach the log.
Edit - don't worry about the lean when you are off the pedal - I missed one of the DFCO disable parameters - its normal for it to do that, but I meant to shut it off while we are tuning... it will be off in the next tune... when we are done tuning, I will turn it back on. You want it to lean out on deceleration - keeps it from loading up on fuel.

Here you go - can you still load this tune? Hope so - even if you can't log it, load it up before he takes the cord...

Don't worry about the lean-out on decel, that is normal...
It is dialing in really good. It will be hard for me to really optimize timing without you putting it on a dyno - I'm going on experience with somewhat similar setups and being conservative... But, if you aren't looking to totally max it out, it will be okay. Like I said before, tuning something like this over the internet isn't easy...

Ill be loading and logging this quickly. Luckily he hasnt left yet. Anything specific you want done?
Wide open in boost for as long as you are brave... or at least through 2nd and into 3rd gear...

damn! I just got that msg as I got back. I have some harder acceleration on here. If its not enough I may be able to do a second run. not a big deal.
It's looking great! Here are some more changes. If you can't go back out, don't worry about it now... we can always do it later.
