Thanks I was just making sure.

Ok but the other input values for gear/tire wizard are missing. The gasser I worked on I could input tire sizes and gear ratios as well as choosing whether I wanted to automatic scale or manual...

I'm working with a 2002 LB7 w/Allison on a Chevy Silverado added bigger tires to it and wanted to use the Gear/Tire Wizard but I don't get any options to add anything just the multiplier. Am I...

Can you post the tune? I've been goofing with the Hypertech tune but if you found another way with the lockup I'd like to see.

I know I'm late to the thread but wanna thank you guys for helping me out. This thread has been a big help

Thanks, I'll try that.

Sorry for the late reply and Necromancing the thread BUT if I'm going to use a 02+ OS for my truck and still keep the stock calibration do I write the entire 02 OS with my tables or do I write the 02...

Yup, did look at the image I was just confused where it was drawing the temp data. Looks as though you built the logic into the harness. Cool deal. Actually at this point I would just need your logic...

Morning ya'll,
Haven't been able to play much with my Hptuner for actually tuning but was able to use it to enable an efan conversion. I used parts off a 2005 Silverado to get a stock 3 relay fan...

Oh aha I see what you're doing. Yeah I don't think there is a way. Hopefully someone smarter comes along and give a definitive answer. Sorry.

Just wanted to add I've been lurking the thread and wanted to add a thank you also. I have a stock 99 LQ4 truck and this is helping a ton.
