Well, tried another MAF tonight and still bloody detting!

Could anyone with a conzult try to get a MAF voltage reading at 2000rpm, stationary please?!

That would at least show me if I'm barking up the wrong tree!

Better start looking for air leaks when I'm fitting my intercoolers then :cry:

you have a PM mate.

 

According to the Conzult manual the correct reading with warm engine, air con off, neutral gear, no load at 2000rpm is 1.40v - 1.80.

I checked several logfiles of different cars and they all seem to be around 1.40-1.60 volt @ 2000RPM

Thanks Eric!

I guess that inaccuracy in the TP formula is at low revs then?

Still the timing should be 15° shouldn't it ?

John if you want I can rig the conzult up tonight and run various tests why you are on the phone if that helps mate

No, timing should be near 35 BTDC, but depends a bit on what tune you have.

since there's no load, the TP is low (5-8), so you should look at the first table of the map.

 

and, yes..most TP formulas I have seen are only reasonably accurate for midrange RPM's.

Cheers Ryan, working late tonight but might take you up on it soon!!

No worries mate

That's kind of what I was thinking, but then how come the stock timing check procedure gives 15° at this condition (which my car did last time I checked it)!

don't know where you saw that ?

 

according to EFEC page 59 timing should be over 25BTDC @ 2000RPM

and at idle (~850RPM) timing should be 15BTDC

Mmmm, I'll need to double check the manual!!
