    LB7 $0544 when attempting to activate license

    Buddy just got the truck, no clue on its history, no telling being an 02 lol. He is actually aa big wig at the local gm dealer so he could get it reflashed there for sure. I've read some about continuing to try to access it and it will eventually give you a serial number but I've tried at...

    LB7 $0544 when attempting to activate license

    Yes it is up to date, actually just loaded it onto a new computer last week. Tuned a couple lbz's without issues, but I'll definitely try the reinstall and see what happens.

    LB7 $0544 when attempting to activate license

    Got a 2002 lb7 here. I can read the tune out just fine. VIN number is good, no crazy characters or anything. When trying to activate the new Vin license so I can flash it, I get the $0544 invalid serial number code. The serial number comes up as 0000000000. Anybody deal with this before? Is...

    I know Matt Woertz has used some rather large ones with no complaint. At least 300% for sure.

    Question: WiFi Extender for Shop

    As long as the power for the shop comes from the house panel, no extra cable needed. Uses the electrical wiring as the pathway. Pretty wild really. I went to my ISP and picked these routers up.

    Question: WiFi Extender for Shop

    I am so glad you posted this. Never heard of it before this post, picked up some TP Link Deco routers setup for this, plugged then in and away I went with internet in my shop. Same speed as the house. Shop is maybe 200' from the house

    LBZ: Latest EFI update has screwed me

    So where does a guy get everything to make it work on XP? I don't want a new computer as my tuning computer is the only one I have, and the only thing I use it for.

    34mph back half in a 8k# truck is crazy.

    LMM 7.70 build

    Tail gate, bumper, hitch, spare tire/hanger, sway bar, washer fluid tank, second battery, and back seat was about it. Try to have less than 1/4 tank fuel. Just the radials on PYOs would loose hundred pounds of rotating weight. Really doesn't take long to get all that stuff off either.

    LMM 7.70 build

    I ran a billet 475/stocker setup with 40% Inj with a stock pump and went 7.4x all day long in a CCSB stripped down some. M&H radials with QA1 shocks and Caltracs. Doesn't take much to get down there.

    LB7: P0727 help

    Well figured it out. For anyone wondering, when the TCM loses that front sensor input signal, the TCM will use info from the ECM gathered rpm for turbine speed so it will still show turbine speed on a scanner. The real issue at hand was that alldata had the wire color and pin location at TCM...

    LB7: P0727 help

    Thanks Mike, sensors were both changed, clocked correctly, and swapped with each other. Not looking like there is anyway to check the dimples on the converter other than pull the trans. Weird that the data feeds in the scanner are smooth and correct.

    LB7: P0727 help

    Swapped a trans that was slipping in 5th gear. New trans is built with Suncoast converter. Getting the P0727 immediately at start up. Tried new sensors, tried swapping TCM, checked all the wiring, no shorts no open. What's weird is everything on a scanner looks great. Turbine speed is...
