Can the R32 be tested on a 2 wheel dyno?
A. Yes. But first you have to disable Haldex. Per Rich @ EIP in response to a question by pl@gu3: “You can simply unplug the main harness connector to the Haldex ECU (located at the back of the rear differential housing). Be sure to have the car turned off when disconnecting and then re-connecting the plug. The car will then dyno just like any FWD vehicle. You will get a light (EPC / ABS if I recall correctly) when doing the runs as the ECU will register a code for the Haldex ECU being disabled and for the ABS sensing the difference in wheel speeds. The light should reset after re-connecting everything and then driving the car then cycling the key.” I would add that the R32 should not be run this way on the dyno for extended periods of time as it’ll heat up the hydraulic fluid in the Haldex unit, because it never really stops pumping.
