I ran every tune extreme,80hp,50hp and tow. Each one was run for two days and every trip made the truck cycle regen and stayed in it. I have gone back to stock and have given up. It costs way too much when the truck is dumping all that fuel. Time for other beta testers! Just hope you never get ...

Since getting flashed the l30 I have noticed that when it goes into regen it displays only for a few seconds where as previously it would stay displayed in the instrument cluster the entire regen cycle. I also get a message that says "drive to clean filter"(or something like that)
I have ...

Don,
The truck has 45,000 km's on it.
I have been running stock for the last couple of weeks with the usual cycles of regen(about 2-3 times per tank)
Would you like me to try econo again to see if it regens more frequently?

I tried the econo tune (50hp) and still goes into regen every trip guzzuling a nice 22l/100.

Two days ago I put it back to stock because I was sick of losing all that fuel. It's no longer regenerating in stock after about 90km's

We know these 6.4s are sensitive to regen but WTF!? what a pain in ...

Don,
Here is some prelim results for the new L30 crom.

My driving habits are easy on the throttle and 90% HWY @ about 100 km/h

I loaded the 9t12c the other day using the 80 hp setting I found:

Truck went into regen after about 5 minutes. Thought it was just a fluke but then it cycled again the ...

Don
Thanks for the test crom
I loaded it and gave it run in the 80 hp
Everything seems good and very similar to the 9r11
Cruise and TCS is functioning normal

I couldn't play too much as regen kicked in after 3 minutes(hope it's just a fluke)

My order of preference is
1. fuel economy
2.driveability ...

thanks Don

Don,
What is the progress of the 9R11? Are you working on the unsupported calids? Mine is supported so if that is final with no more adjustments then pls fire it over.

I plan on using the performance or economy tune strictly for fuel savings. Which do you recommend? I also tow a travel trailer ...

Don,
ran the custom economy tune you sent last week....
Fuel consumption was exact same as stock.
Cel light thrown.
Regen normal intervals(about twice per tank)
Cruise ok TCS ok
looking forward to the 9r11

Is it safe to drive the extreme tune without an exhaust temp if you are just babying it?
truck is bone stock

Thanks for the custom tune Don,I installed it last night.
I tried the performance tune first and i liked it, but no cruise. Tried the economy custom and it has cruise but the turbo boost does seem to run high. Will have to run a tank through(which could take a while due to being laid-off)to get the ...

Hey Don,
I have been waiting and reading for the latest crom and very thankfull that you are on it!
I am most interested in fuel economy then power followed by towing.
Can you please send me one of the tunes that you have that gives the best fuel consumption numbers?
Would I still need to download ...

Man do I wish that I read this forum before I went for the dealer update.
Since I do not have a cable to load from my computer to the tuner, I guess I will have to send the tuner to Diablo?
