New guy with 8.1

[azcagiva]

Hello everyone,

I have recently received my v2. I have removed the torque reduction in the traction control (I think), calibrated the speedo, and changed the PE setting. I had a few issues with getting the v2 to flash but eventually got it to work. Luckily it did not work at first because I had forgotten to save my stock tune. I am having trouble getting the scan tune to work. I will make some more adjustments once I get it to work.

My truck is a 06 2500 8.1 w/ 6 speed allison. I have it converted to propane. I would like to increase the timing a little to take advantage of the higher octane of propane. The truck runs on both gas and propane so I was wondering if there is a way to switch the high octane curves (one for gas and one for LP). I want to avoid any detonation on gasoline. (I rarely run it on gasoline though.)

I have been searching but have found little on the 8.1 so any help would be greatly appreciated. I am a little overwhelmed by this process and am still trying to figure out how everything works. I am not even sure if I posted in the right forum.

Thanks

-John

I have been playing around some more. I had the TM stuff wrong. I pulled 40% out of the TM table and set the tip in TM to 0. I added 2* more to the high octane table. I set the DFCO to 3 seconds.

Just removing the TM made a huge difference in power. My mileage is up a little as well.

I will have some more time this weekend to figure out the scan tool stuff. I have to download the newer versions. I think that might fix my problem.
