Default Dyno setup

I'm going to be getting my truck on a dyno hopefully soon. I want to see before and after numbers. Going to be putting lds 63.5 wheel and housing on my stock charger. When looking for a local dyno does it need to be setup different putting a diesel on vrs a gas car. Just wanted to make sure incase the place I find doesn't do alot of diesel trucks

When they do a pull will they need to eas into the throttle so I won't downshift or is there a certain rpm to start at that should downshift. I have OD lockout.

Ideally, hook up a laptop with EFI and lock the trans into 4th gear with the DVT controls. Or you can write a trans tune that won't allow a shift to 5th, and will only start in 4th gear when you tap it over to T/H mode.

Does flashing a new trans tune reset the taps? I wanted to go out and do some testing, but didnt want want to flog it without the shifts being learned?

If you do a cal flash, it won't reset anything. Full flash will.

Some dynos won't do diesels because they are afraid of smoke sooting up their dyno room. Every time I have dynoed a Duramax at a random dyno in CA, I spend 20 minutes convincing them my tuning barely puffs when you stab the throttle then cleans up. And every time, they are like "wow, that is so clean, I have never seen a diesel run without smoke!" Fricking coal rolling tools ruining everything for me

I like to write a trans tune to lock it into 4th and 5th in Tow/Haul, then pop it into T/H on the dyno. If you don't have the power to pull in 5th, use the overdrive lockout to pull in 4th.

I prefer the trans tune to DVT because I have never been able to log while using DVT, it always kicks DVT off. Just seems to work better with a trans tune, IMO.

That doesn't make sense, why wouldn't it reset the TAPS if you full flashed it? Or does it just activate the fast learn?

Interesting. I have only ever full flashed a different operating system in so every time I full flashed a TCM it reset the adapts. I assumed it was because of the full flash. I'll have to try full flashing the same tune back in and see. I'm curious now. Lol

you guys may be right but i swear thats what we did on my truck when we did the TC lock up addition when it first came out in beta and steve did it all. i was paranoid about loosing the adapts i had already but we pulled the tune in my tcm, made the change, then flashed it back in and lost nothing. i could swear he said it was a full flash but that was a long while ago.

I'll bet you were just doing a cal flash. How long did it take to flash do you remember?

Is there a big difference in power results between dyno in 4th and 5th gear? I got a chance to dyno my truck at a car show, so I did. I ran it in 5th from about 1800-3800RPM to keep from being too smokey. It would be kind of interesting to see if the power read higher in a lower gear, the dyno operator wanted to run it in 3rd gear, but I figured the pull would be to short or the truck would shift.

5th would be higher, and arguably more accurate, but those net very high wheel speeds. Most everyone dynos in 4th, HP would be a touch lower but tq will be up (if the engine has enough load to make full boost)
