Which Dyno?
 

We have a Dynojet 248H and a Mustang Dyno a couple miles from work. They both are available for $75/hr. Which is the better dyno to tune on? Neither will have exeperience with the Adaptronic so tuning expertise with my ECU is somewhat moot.

Both run dyno days every 3 weeks for $50 for three pulls if I just want to get on. Might do that for fun just to see where I am at but I really want to spark tune as soon as I get this thing tidied up a bit and get the EBC on.

Mustang dynos are what men tune on.

mustang? I dont think the 248H is a loading dyno, but the mustang is (check?)

it doesn't really matter though. I'd wager you could set the rapid learn parameters to do quite a bit of tuning with just a regular dyno pull.

Ignition may be a little more finicky, but who knows? with a loading dyno, you might be able to just set the ramp time to a long time and let the rapid learn do what it needs to do.

mustang is more like real raod experience id go with that.

Or just set it to hold 4000rpm, then use the throttle to hit each cell on the nose for a few seconds while your autotune does its thing. 100% perfect fuel map in 20 minutes, anyone?

A dyno that doesn't have a load-bearing feature isn't a real dyno, IMO.

in my experience it's more like hold 4k and overheat your car in 45 seconds with no airflow... let cool for 5 minutes. could have been inadequate fannage at the shop though.

the operator also didn't know how to hold RPM with the dyno which was also an issue.

Good info here guys, I think this thread deserves a sticky.
