Even Works With EFI Live

Reviewed By Andrew S (St George, UT) Reviewed for a 2008 Dodge Ram —11/16/2015 10:25 PM

I bought this to fix my speedometer on my 2008 Dodge Ram 2500 Diesel. I was running 37" tires and went to 35" tires to fit a spare under the truck. I couldnt adjust my speedometer with EFI Live that I already had, so i bought this. It worked perfectly without having to reset the truck to stock. It took me a while to get the truck perfectly calibrated but now its dead on with my GPS.

The Mean Green Machine gets Calibrated

Reviewed By John I (Robinson, IL) Reviewed for a 2015 Jeep Wrangler —9/15/2015 4:06 PM

Super easy, best bang for your buck. Took a few minutes to download the software on the FlashCal then off to the races. I put a lift and a wheel and tire package on my 2015 JKU. It calibrated the speedo and adjusted shift points so it pretty much drives like its stock but better. A nice thing too, for $90 you can upload you FlashCal and turn it to a flashpaq and get some power and fuel mileage settings. I did see an increase in fuel mileage also, and it works great with my air intake.??
