Do all Dyno dynamics dynos work the same or do different dealers set them up in different ways?

Some (including JKM) set up DD dyno up properly and understand how to extract meaningful information ....... others haven't got a fecking clue what they're doing!

Iirc Shootout mode allows the software to do the work alongside sensors, negating the chance of operator errors. This is why you get very consistent figures between different dyno dynamics Rollers. So the variations are only from strapping, what gear is used and what cooling fans
Hurdy:
227bhp and 230lbft :happy2: Lower than expected, but the way it is delivered and spread over a wide band shows how the wmi helps. Not too shabby for a 1.4 with just a zorst, map, intake and wmi. Next stage begins next week, Loba LO270 hybrid turbo, intercooler and another map. :party:
And again thanks to everyone for organising the day and the drive down was immense :evilgrin:
Graphs just for Janner.....
Silky smooth AFR.
Gorgeous spread of torque of 225-230lbft held from 2500rpm all the way to 5100rpm and only dips below 200lbft just before 6000rpm
Power curve is lovely and smooth too and tops 200bhp at 4740rpmand still holds over 210bhp at 6800rpm

:drinking: replied in your thread. Good figures there :happy2:

Shootout mode is extremely effective, but there are other factors to consider such as the rpm that the run starts, how the operator calculates the RPM reference ( the dyno needs the operator to input an RPM reference as a factor to calculate torque) you can use various methods such as inductive pickup, pulse feed from an injector or roller tacho. Roller tacho is the easiest and quickest. However if the operators rpm input is 200-300pm out this will cause low/high figures.
The most important thing is to be consistent, there are no definite right or wrong methods as such but if you stick with your chosen method you wont go far wrong. Dynos are tuning tools, not power comparison machines.
