Just downloaded a stock lbz file and the only modified one to compare. I noticed that only one of the main injection tables was changed and if I remember correctly someone said the different tables refer to elevation correct?

Knowing that and the fact I live around 347 meters above sea level. 1100 to 1200 feet. Which table would I fall under?

What exactly is torque reference?

I saw that on the LLY you could turn the EGR off, any way to do this on the LBZ?

Thanks for the help, I have spent most of the morning reading posts, hoped for a write up for the LBZ like McRats 20-20 for the LLY but didn't see one.

You're definitely in the low altitude table C.

I don't know the exact cutoff points, but table C is good for up to roughly 5000 feet, Table B covers maybe 5000-12000 feet and table A covers everything on up (Mt Everest?).

To disable the EGR:

Set B1503 to 160 and B1504 to -40.

I think SSonnentag correct but I just do both b and c for good measure but I do travel aroung the country alot with varying altitudes. just my 2 cents.
I sure wish more people would post LBZ tunes in the repository for me and other efilive users to look at. hint hint wink wink everyone.

Ok I just updated the LBZ Cal linking patch, and the other update. That's why I couldn't find the EGR at first. I downloaded them erlier but didn't install them correctly. DUMB me.

This is real fun to tinker with, too bad the high today was -16*C.

carcrafter22, I agree we need more tunes. I opened yours and compared it to a stock tune to see what all you changed.

This place is just AWSOME!!!

I sure wouldn't mind if you posted that nasty tune your runnin, hows your tranny holding up? I have a Transgo Jr. which should help out alot. The most I've ran was about a 150hp tune which to me felt very fast. can't imagine what yours is like.

LBZ altitude tables are a little different to the LLY/LB7.
The ECM will process all the altitude tables in one pass, so it gets the values from all three altitude tables. Low, Medium and High.
Then what it will do is refer to table B0202 to get the multiplier value for each altitude table to come up with a final result.
The mathematics are -

(Low Alt table value x Low Alt multiplier in B0202) +
(Med Alt table value x Med Alt multiplier in B0202) +
(High Alt table value x High Alt multiplier in B0202) +
= Final altitude adjustment value.

Cheers,
Ross

Thanks for the info ROSS!! One of the reason I went with efi live. It's great that yous are on the site and assist. Most companies don't even help if you call them.


I just got back in the house. I'm going to need some tires soon if I keep tinkering. Got a little too much fuel I think now, little bit of smoke :D. Poor people watching me drive. Wasn't really able to tell the boost because I couldn't keep the tires on the pavement, 265's and COLD pavement. Seen a spike to 27 or 8 PSI. Going to start saving for a trans upgrade now. :cool:

When does the computer turn pilot injection off? It sounded like there was none when I'd get onto it around 90 to 100% throttle. I remember reading it turns off when power is wanted. I havn't changed any of those values yet so they are stock.

On another note, maybe this is covered somewhere but I missed it, I can't get all my dashboard to read. The following items are giving me a red X in the scan system. Can't get accurate numbers in the gauges. PID's
Actual Fuel Rail Pressure
Barometric Pressure
Main Injection Fuel Flow Rate 2
Main Injection On Time
Pilot Injection Fuel Flow Rate
Pilot Injection Timing
Turbo Boost Pressure


Thanks a bunch!!!!

Anyone with info about my previous post?

Thanks
