Then how come people with Kh motors can just spring the WG and get
1.8 bar??I ran around with 12 lbs of boost for the first day or two untill
I got my WG - IM Hose repalced (it was plugged) I have the FPR cutoff
installed but it never happened. Again, not saying your wrong, just ging
off my experience try ing to understand it. Many people have told me
(well a few people) that the Mac-07 had a higher cutoff. i thought the
suspect was that this ECu ws designed before they decided to limit boost
for Us market and they changed that just by doing a spring and left the
ECu the same.
Mroe Misinformation I guess. But if your right, then my wire
giong from ECu to pin BS on fusebox should cut-off FPR at 1.65 bar. it
doesnt. I wonder why. Another wiring problem on my part??? Probalby
knowing my wiring. :-)
So how do you get 2.0 bar from KH??? I dont know of any chip
tuners that can modify this ECu. Scott Mockery told me he couldn't modify
it. or was he just atalking aobut the timing maps?? Not sure. I spose I
could just leave it the way it is. :-)

So whats the difference between the MC-1 and the late KH. They
sound Identical. Different head (MC-head) with KH block???

Ahhh, thanks. That explains the Bently secton that shows the MC
with the same IC as the KH and same plumbing from there to the ISV. I
was confused on that one.
