Andy-R. Wouldn't you rather know the HP at the wheels anyway so you know what power you actually have at your disposal.
Hi, all rolling roads measure the torque at the wheels. This is then converted to wheel HP, and then if required calculated flywheel/crankshaft HP. We find 99% of customers prefer the pub number, however the wheel output is the most reliable IMO and quite often (especially with bikes) we tune or map using the wheel output. This is due to the variation in transmission losses that affect some vehicles notably 4wd. I hope this is of some help.

08-01-2017, 05:38 AM #12ike, can the is300 be put on the rolling road and dyno tested as its auto and cant keep it locked into one gear, is there a solution to this?

Bobby I had my old Is200 dyno'd & it was an auto.
ok seem to remember a topic on the other forum about a year or so ago people werent to sure as apparently the auto gearbox kept slipping between gears and so not being able to keep to a set rev limit or something along those lines?? not 100% sure so just checking. has anyone else got any info?

Marsdendean I think Wozza managed to get a figure which was near Steves, and his is an Auto.
Problem with the IS200 is you can't lock it from kicking down, so Wozza had to try to "coax" his into staying in a gear, you can however lock it into gear, so can rev it 5000 all day long
so whats the trick in keeping it in gear? also im assuming the gearboxes are different between the 200 and 300?

capability of e-shift so you can hol dit in a gear?

08-01-2017, 08:41 AM #16i would have though you'll be more likely to be able to dyno the 300 as it has the
capability of e-shift so you can hol dit in a gear?

[QUOTE=DJ I would be interested how they did yours Bobby ?[/QUOTE] Over a year ago now Wozza so old grey matter a bit foggy. But he did get readings & that was two different dyno's, will dig out the paperwork for the runs if you want.
