LBZ race tune

[JoshH]

This tune is what I'm running in my truck right now. I changed the tables back for non twinned trucks, but other than that, it's the exact same. You'll need a lift pump to run it.

Edit- I have updated this post with the correct tune for Josh.

I had trouble last night august 29, 2008, with my truck for some reason I couldn't break out of the 15's then finally I made a 14.6 e/t at 95 mph with this tune for some reason my truck threw a mass air flow sensor code and absolute manifold pressure code cleared them both and it did it fine. For some reason right about the 1/4 mi marker it would throw the codes and feel like it was defueling and then pick back up but by that time I had already broke the 1/4 mi sensor beam. Not sure what was wrong with my truck not making the high 12 to mid 13 sec pass I had planned on but the humidity and hot air temp were playing a big roll at the track the denser air was harder for my air filter to draw in I'm geussing any way great tune.

I've been playing around with Josh's tune for a few weeks now, and it gets a little faster every week. Down to 13.0 @103 now, bet she's got 12.9's easy.

Couple of things to check:

Have you logged rail pressure? Did it maintain?
Do you have the same OS as Josh, or did you manually have to convert it?
I popped the high MAP code, but I think we've got that solved, we'll find out tonight.
95MPH is good MPH for a 14.6, are you hooking up when you launch? Gaining 0.4 in a night is huge, the variability might be in coming off the line.
315's might be holding you back a 0.1 or two.
Post your fuel logs and I'll try to help with some of the tweaks I had to use tailor it to my truck.
It is a pretty sweet race tune. Easily in to the low to mid 13's with your combo.

Josh, do you have a tranny tune that you reccomend to run with this? I have 2 tranny race tunes and both shift at 3800rpm.

I have a 2006 LLY detuned LBZ OS: 12603624 is that what you need

 

[racinmike77]

Here is the scipt assuming Josh has a LLY or detuned LBZ. Josh, if you don't want this here It may be removed.

This the script of 3624 stock or Josh's tune? I didn't know if there was one for an o6 LLY and a different one for an LBZ both 3624. I found the LLY one but didn't know if it mattered.

Use that script I made for you and tell me how it goes for you

Thanks bud! May just have to try that this afternoon.

[racinmike77]

Ah man that sucks. Time for a security system with lots of lights and sounds.
