Which gear for dyno tune?
When doing a dyno tune, 6l80e transmission, does it make a difference if the Camaro is in 4th of 5th gear?

its reading will be off. Some one on here said there shop accidentally dynoed his car in 3rd and it read low. So in 5th it will probably read high.

from my experiance dynoing different things, the gear dosnt matter. the reason they do it where it its 1-1 is so it gives a good run with less chance of the tires slipping on the drum and a smother run. the reason to not run it in 5 of 6 is just because of the speed it would have to spin the drum up too.
I know on our dyno here that runs I. different gears are normally within a few hp/tq. it can Chang that much with just the air quality in the room, engine temp, ect. same goes for an auto car, reads the same. also goes for when you change rear gears, you still get the same hp/tq reading. the way out dyno (dyno jet) works is it figures out tq by figuring out how fast the from is accelerating (using rpm change) which gives you the tq. with the tq reading and the rpm reading it can calculate hp for any give. RPM. Last edited by climb-101; 09-18-2015 at 09:15 AM. |

I'm sorry, but there is no 1:1 in the 6L80.

You use the closest gear to 1:1 which is 4th. My guy dyno's my car in 3rd gear(6L80) because of the high mph on the dyno. That is ok with me as along as I know about it and he does it every time. I just want to see the hp changes with the mods I do.
