Ign 1 shows cyl. 1 timing advance and correction, you want a smooth curve without hard drops of several degrees indicating knock. Ign 2-4 shows cyl 2-4 corrections and should ideally stay at 0, if you get longer timing pulls with 2-3 degrees or more and/or on multiple cylinders you should adjust or look into other issues.What are desirable timing corrections. I am getting zero a lot when at full boost (22 psi)
max on jb4 with e30 like 9-10 is good, some cars are maxxed out and get like 8 tho, depends on weather, gas %, other FBO mods. I think I have only saw like 1 above 11 and thats hooningAgain....I am getting zero degrees on ign 1 on full boost. How many degrees are desirable.
The NA 2019s runs richer than older GTIs, my Euro 7.5 performance was always somewhere inbetween.What extra fuel does the 7.5s get?
If that is pure pump ACN91 you are really lucky, probably higher than 10% ethanol in that pump.
