Yeah it's richer than before. I guess they are just trying to keep it "safe" which in my book is a good thing. I was sure John said last time that my timing was on 250 but as it turns out I may have miss heard him. I plugged in my consult and it said 50 which he confirmed when I spoke to him.
This was with the CAS in a central position. To get 150 he had to turn it to maximum but it was pinging badly.
This led him to believe my Caltex fuel was to blame but also the timing belt may have been out by a tooth or 2. (all leading to a belt and water pump replacement)
I was there yesterday when he got to the belt etc... and he found that the timing marks all lined up but there was a bit too much deflection in the belt. (Gates Belt) which may have caused the timing weirdness.
After putting on my New Belt today (Dayco Belt) he had it at 150 but due to pinging again, he had to pull it back to 120.
Suspecting the AFM he switched to one he has in stock and that 192.4kw is the result but I suspect it's still at 120.
But yeah, they reckon it's almost like the compression is higher than it should be? They had to keep adding fuel at 4600rpm and above which he said is unusual.
So Hopefully with my spare AFM or Richard's, he may be able to lean on it all some more and get the timing & AFR to a nicer end result.
and if not, well at least I've had my Belt and Pump refreshed. Oh and I got him to change my Brake Fluid while they have it there.
