I haven't had the time to try the higher delays yet but I did find an interesting forum post yesterday.

It mentions that DSM cars are were unable to use the delays straight from the EVO roms because the EVO ECU's use MOSFET transistors which are much quicker than the transistors used in the DSM ECU's.

Seems like EVO's from 98 and onwards use MOSFET transistors.

I wonder how the transistors in our flashable ECU's compare to the ones used in the 98+ EVO's.
