Re: safcII help
The bigger the injectors the more likely you are going to have knock/detonation problems at medium airflow because of too much timing from going negative on the SAFC or by putting on a 2G MAS. At high airflow(race gas boost levels) you are less effected by being very negative in the SAFC, because of how far off the top of the timing map you are, and race gas also tolerates a lot more timing. Putting a 2G MAS on a 1G tricks the ECU in exactly the same way going say -18% on the SAFC does. The 2G MAS just reports less Hz to the ECU than the 1G MAS does at the same airflow. Some people are fine with 650-680cc on pump gas with an SAFC, some have knock problems and some don't give a crap or log their timing/knock and run it until it blows up or the compresson is down to nothing.
