Those that have installed a PCV and Autotune, what wire did you tap into to power the Autotune? The Red wire from the Autotune.
I would like to try your map. Please send it to [email protected]Update: I have a 2010 Voyager, PCV (Fuel & Ignition) with Autotune just installed, K&N Air Filter, Cobra 4" Scalloped Tip Slip-ons and the exhaust manifolds wrapped. The map that came with it was for a stock 2009 Voyager. I rode a 30 mile loop I ride sometmes and immediated noticed the engine ran smoother, had more power and torque and the gas mileage increased based on the computer. I know they are not accurate but prior loops I got 43-44 mpg. Today it showed 47. Looked at the trims when I got back and took some fuel out in some places. Accepted all trims and saved. Went back out again riding 2 up and rode about 80 miles. Again, noticeable difference in how the engine ran, the HP and torque. Was really noticeable in 6th gear on the highway. MPG showed 44.5. Really impressed with the setup for now. I will continue fine tuning the map and will share with anyone that is interested.
I agree to that 100%. I've been saying that to other guys but I don't think they believed me.The dash MPG has no idea your PCV is modifying the amount of fuel the ECU is sending to the injectors. The only way to calculate MPG is to keep track of mileage and fuel receipts.
The onboard computer knows the RPM, what gear you are in, how fast you're going and how much fuel is being used and how much gas is left in the tank at any given moment. From those information inputs the onboard computer will calculate your miles per gallon and range.Wbilotta,
How is the information on the dash LCD calculated?
