PG, quick question on dynoing. I am planning on putting together a dyno day in my area with a few other BMW buddies. The shop everyone wants to go to has a Dynojet Model 424xLC2. So I am guessing I should dyno in third gear. What sort of variables/inputs need to be input into this particular dyno for me to get the most accurate results. I am thinking of doing a pre-dyno prior to perhaps installing a UDP and software...

The Dynojet is an accelerometer based dyno, so the runs are based acceleration of the drum and you can't "game" the system by varying the runup time. I'm very pleased with Mac, with the three runs costing only $65. If we could get the programming they would do dyno tuning as they do on most Asian cars and most recent US brands. It was comforting to see my air/fuel was not too lean (a common problem at altitude) so they're predicting good results when I add the throttle bodes and exhaust. Of course, I'll go back for comparison runs after the mods are complete. Dave |
