Yes 6L80, it is very fast I’m not on the parameters of the shift points. But I let the wife drive it, burnouts everywhere I told her it was sensitive. I’m still learning hptuners so hopefully I will get it turned down. So at least I won’t have to buy tires all the time.
That's awesome.. I have the gen v L86 in a Yukon XL with a low duration cam(L83), it's so much fun to just stomp on the pedal and let it rip from a rolling stop, it never gets old. It has surgical throttle response, I've torn up a couple sets of tires. Praise baby Jesus for traction control, I'd have put this thing in a ditch more than once without it.
That’s awesome, great job. I love cam swaps they really can set the tone of a vehicle. I’m still hesitant on stomping on it yet. Yukon’s are fun to drive, my oldest just started driving at 19 I’m hoping she can find the fun in it as I did. Our area is growing and the back roads aren’t back roads any more. Snow is in parking lots are best we get these days.
Update: Yesterday I went into hptuners I couldn’t change the tire size but I could change the gear ratio it looked like the ECM was at 4.10 and the Yukon was 3.42 so I did change that. I also disabled the rear o2’s because I had to steal the Y pipe from my 2005 Chevy pickup and the cats were already cut out of it. There is a way better throttle response now. Eventually I will get a new Y pipe. I welded in an extra cat just before the muffler to quiet it down a little. I imagine this will not help the MPG as much but. 3.42 should make a difference in the calculation. I will be driving it again this weekend 300+ miles and I will have some results. My wife drives it everyday but only a couple miles. It is 14 mpg now so hopefully will see what the weekend brings. Just thought I would give you an update I’m trying to learn all the schematics of hptuners as well so I’m not changing anything I don’t know what it is.
Way to go and I admire your courage to just set out on the journey, come what may. And you got it done!
I bet it does, I would love to have 4.10’s. If I knew they had suburban’s like that I would have bought it before the Yukon. I have to take a break on spending though. I over did it a little. Getting past their direct injection and immobilization was ridiculous.Way to go and I admire your courage to just set out on the journey, come what may. And you got it done!
I have the L96 in a 2018 Suburban 3500 HD, and it's a beast. Smooooooth runner, too. With 4.10 gears it can really haul a camper.
I have no doubt. Very, very impressive work.
