Danville Performance

Alright, here's the second video in the tuning comparison. This will be Danville and there was some confusion on the last video. Some people thought that I was doing more than one tune. That was all PPEI and this whole video will be the Danville tunes from Mark Brovac at Danville Performance and it's been taking me a long time to do these tests because I go I try to get almost 200 miles on each tune for the mileage. So tune 2 gets almost 200 miles, tune 3 almost 200 miles. So that's what's taking the longest time and I decided to do it that way to try to keep it consistent between tuners. I'm trying to do them back to back that way if I fill up and get a couple more ounces of fuel in one tank than the last tank. It'll even out so that was my plan there. Alright, this is the tune 3 and I figured it's a little bit easier to show So on a wide open pull you will see that the main injection pulse was a thousand eight hundred and ten on tune 3. Now on the PPEI it was twenty three hundred and something. This is only eighteen ten which is a lot lower and the main injection timing right here is twenty point eight degrees and then PPEI was thirty. Now the difference is Danville is let'see the desired fuel rail the maxim Okay on Danville performance max effort tunes he commands twenty eight thousand fifty ultra seconds for how long the injectors are open and he's commanding right here twenty eight degrees of timing so that's three degrees less than PPEI and only fifty ultra seconds less. He's also he's keeping the twenty nine thousand PSI rail pressure though that's how much he's commanding and that's actually how much the truck was running. So the fuel mileage between the PPEI and Danville were exactly the same and that's the average over five or six hundred miles so I'm surprised that they both came within point zero one mile to the gallon on both of them. Alright so what I didn't You can see the video from a stand still on the wide open poles the PPEI tunes would spin the tires pretty good until 60 miles an hour and the Danville tunes actually had a hard time spooling tires unless I was using the brake which is fine. The LBZ doesn't have the strongest bottom end so taking away some of the torque at the bottom end is completely fine. I'm sure the engine would live longer on the Danville tunes than it would on the PPEI tunes for more than just the torque and I'll tell you that here in a second. Also one thing I didn't It still runs awesome and I have to say they I Another reason why Danville tunes the engine will probably live longer even though I didn't
