What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[RooTBeeRthe1st]

What did you have to modify on the fans?

I had to trim some flanges that stick out near the top and on the bottom. Made the shroud flush.

Filled the Denali at 2.54 a gallon E-85. Took 23 gallons.

Made some washer fluid today, 6 ounces of GM OptiKleen and 42 ounces of distilled water then put it in the truck.

Coolant reservoir looked a tad low and the engine oil looked a tad high. Shut the hood. Tried to get my darlings to wash and vacuum the truck, no dice, they left me.

Question: Data log for BBP tune in M5 or Drive? I have to unplug my range to do it and don’t really know if I want the AFM to activate.

they want a stock file, no range device, no tricks, just put it in drive and drive it, they want about 20-30 minutes of normal driving with some full-throttle pulls mixed in.
so somewhere on your drive find a place where you can go from 0-100+ is what I would recommend.

What Wes said ^^^^^^

part of the reason they need a stock file is because when you get your tune it will overwrite the stock file, should you need to put the stock file back on it is included with the tune file they send you, you will get 4 files (minimum) 1 ecm tune, 1 tcm tune, 1 stock ecm tune, 1 stock tcm tune. you may also get whatever else you may have requested, ie. tow tune, econo tune, 89 or 92 tune, etc.

Thanks, can do. Sadly it won’t go over 100 mph… yet.

Still need to swap plugs and wires as well as get a solid tank of 89 in it.

Installed a propane conversion kit on our trusty harbor freight generator in preparation for our Yellowstone camping trip in August. Shown here before I finished up the connections. A little adjustment and it fired right up on propane. This way we don’t have to carry any extra gasoline with us.

Does Harbor Freight carry these conversion kits, or where did you get it? Also, how long would this genny run on a 20lb grill propane bottle?
