Dont have VAG-COM but i do have a Bosch KTS 670
replaced guides and lifters etc on 1999 golf ALH Auto after bought off a mate, that had slipped the belt by about 8 teeth and wouldnt start
Got it up and running after skimmed head, new valves, guides and all seals fully replaced inc belt kit.
Vac pipes all replaced, everything checked and Vanes not sticking etc
bit knocky but starts fine,
but totally no power below 3500rpm, then like flicking a switch at exactly 3500 it takes off like a missile, keep your foot down and it keeps pulling to redline.
back off below 3500 in any gear (manual and auto shifting it) and again, very very gutless, bordering on dangerous infact.
live readings seem fine, mass air flow, fuel temp, etc
Boost pressure is 14psi (atmospheric, that rises to 32psi peak and sits arround 24/26psi when booting it over 3500) so take 14psi off the values and that is "actual" pressure
boost comes in nice and early as it should also.
ive tried manualy adjusting the pump fractionally each time untill it wont start and got it to its best,
my KTS allows me to use the same graph as VAG COM with the start of injection and fuel temp etc and seems within specs. from what i can see
it has a fault code of "44F8 start of injection control, Control difference"
such a weird one, and its into me for a fortune now and hope it isnt the pump
when it is "flat" the IQ is 23, that drops to arround 20/21 if going up a gradient, but can spike 28/32 when its boosting fine
Please help as i am a bit clueless, got manflu and cant think straight
Thanks in advance, Sean.
