Title: How do I know my AAZ's timing is advanced enough?
Post by: homerj1 on February 14, 2010, 06:11:48 am

Hello everyone,

I recently installed a used IP on my AAZ and timed it to .90+- a bit. It seems to run ok, but it still doesn't have that diesel "knocking" sound (I know a stupid description) until I pull out my cold start.

I also realize that based on the mechanical wear of the engine - an exact setting on the dial gauge is sort of ballpark.

How much higher can I go timing wise on my stock aaz with about 340,000km? When do I know it is too advanced?

thanks

Aivars

I have my 700,000+ km n/a 1.6 timed at 1.02mm and it likes it there.

If pulling the cold start makes it run a lot better sounding, then maybe you should bump it up to around .95mm? pulling the cold start manually gives the pump an extra 4-5 degrees of advance.

Seems the mk3's are stock set at; Engine AAZ  (1.9l turbo)   0.80  +/- 0.02 mm

Some turbo guys advance their pumps to 1.05mm with no ill affects.. not sure what the physical limit is.. or where it becomes redundant.. but 1.05 should even be fine.

Mine's happy at .045 (wayy higher than anyone recommends.........). I believe 0.39 is 1.05 mm.
