disable P0300 test
#31
Both times i've had it, were when cruising at 70mph (bang on) on the motorway after a couple of mins.
If I am above 70 or below, then it's not a problem.
Also a mate of mine with an Evo 5 (e7 ecu conversion) was plagued with it, everytime he went out in the car it would throw up the P0300 code and drop onto 2 or 3 cylinders.
In the end he went back to a 5/6 ecu.

The Evo 7 code does have some significant differences from the Evo 8/9 code. I kinda suspected that the P0300 test was only written into the USDM ROMs, but if you've seen it with cars running non-USDM ROMs, I must be wrong. A different periphery bit may be controlling the test with the non-USDM ROMs.
So maybe it is only the USDM and Euro 260 models (similar to the USDM 8) that have a test.
