Mainline 2WD600L engine power

Hello, i was wondering if there is a possibility to plot down the engine torque/power curve on the dynolog software, instead of the wheel power/torque curve it normally delivers.

There isn't a specific flywheel power function in the Mainline dyno. You can create a math channel and enter a correction in this way but it can't be displayed during the ramp test screen - This will always be power at the wheels.

I have, maybe a dumb question i don't know, another question. Is it possible to put a 4wd car on a 2WD dyno.

By disengaging the center diff or other ways ?

There are a few 4wd cars where it's possible to remove a front or rear driveshaft and run it as a 2wd - We've done this for a local company with a Porsche 997. In most instances it isn't possible though and depending on the centre diff arrangement you could do expensive damage very easily so tread carefully.
