Hello everyone!
I can't recall if this was touched on in the tuning courses or not, but I don't know what gear / gears to tune the car in. I'm getting ready to take my car to the dyno to tune my own standalone ECU for the first time, but I wanted to know what gear to run the engine in first. Do I tune in the highest gear there is? Or the gear that's the closest to 1:1 ratio?
Thank you!
Traditionally, as close to 1:1 as possible.
Might depend on the the rolling road though, it will probably have a maximum upper speed limit.
