Finding a fix for this problem is straightforward when you have a non plug and play ECU like the Motec or Autronic.
It is not so easy for the Power FC, although I believe RB Motorsport are working on a solution for that ECU as well.
As mentioned earlier, the random ignition timing will give rise to lots of detonation especially up in the higher gears. This is definitely a big problem for RB26 engines.

Hugh,
wouldnt this be a problem on the stock ecu aswell??
How does the stock ecu take care of this problem?
Asim..
