Hi.

Am working on a excel spreadsheet to adjust the igniton in FC. To make it easy. It works in the same maner as the excel spreadsheet that adjust the fuel mixture.

Any comments on the max ignition map??? should the limit be higher or lower??

Alsao, is it enogh ignition retard according to how much it knocks??

right now, its only the 2 first knock levels that are used to correct the map, will incorporate the rest tomorrow.

your idea is pretty good

the concept etc is there

just to note - datalogit does this for you in real time with all the data

so you dont have to note stuff down etc and interpolate cells with max knocking

basically you build a knock map in auto pilot mode and adjust from there

in some of my cells im near 50deg timing but thats on light load and under 4000rpm

on max load i can only do about 25 deg ign timing

the idea i did and followed was increaser the timing below 4000rpm until it knocked consistently

i didnt go over 4000rpm and do the same thing living in fear of killing the engine

huh.. What do you mean by this?

Should I lower the max ignition from 4000 rpms and up?

My idea is it shouldnt reach the max.... when i reach the level of knock set, it wont advance the timing anymore...

Was thinking this could be the most cost effective way to find the limit for how far you can advance the timing... as it will advance the entire map were there is no knock.
