Trick For More Horses. Need Clarification

Cubes: the timing throught the rpm is constantly being changed by the CAS right? so to move the CAS all the way to the right would be a stupid thing to do? Is this going to reduce the retard adjustment therefore these cell points will be up to sh*t. Or even bring the timing before 10deg.

What he most probably did was increase fuel pressure, adjust the safc so it wasn't running rich, then retarded the ignition timing via the cas so it doesn't ping.

The cas is a set value, the ecu's map is also set but vary's with load and rpm.

Think of the cas as a base ignition value that makes global a global set change to the internal map.

ever seen dyno graphs where the cars power drops off after around 5500rpm ish? its cos theres too much back pressure on the exhaust

<{POST_SNAPBACK}>

yeah I just saw you graphs I notice the difference when you got the split dump and the GTR fuel pump. The big drop off turned into flat... Well can't argue with that!!

Malpassi Fuel Regulator thats what he used finally remembered!
