Thanks javad, but I thought that if manifold pressure rises the differential
between fuel pressure and manifold pressure will be less, therefore less
fuel will be delivered. So how does cis 3 compensate?
And does anyone know how to put outlook 2000 into plain text?

Alan, the CIS3 system can easily supply fuel to past 10psi, it starts
leaning out around 12psi IME.  No need to richen the CO or anything like
that, just set it to 0mA, you may have to retard the initial timing
somewhat.  There is not any problem with the pressure differential across
the injectors and manifold pressure that I"m aware of.

Hi guys, ive slowly but surely been gathering parts and I recently noticed
something.
On my 84 cgt there was a warm up regulator, this also had a hose which
connected to the im, this, so I was told, would suitably enrichen the
mixture under boost.
However on my 90q there is no such device. So on draw through the cis unit
would measure the air, but not allow for the heating of the air and the
additional pressure on the injector tips so the mixture would be out, this
would be compensated for by the o2 sensor, but on WOT were there may be as
much as 10 psi (realistic) on the manifold side of the injectors the mixture
would really lean out.  Therefore 2 options would be to overrichen the idle
mixture (not the best option) or fit a pressure controlled fuel regulator, a
la the one of the cgt, so is this possible or is there an easier way???
I do want to got to efi but not immediately, after all there is only so much
I can do on 9.6:1 compression (kv/ng hybrid), it should be possible as I
have seen 12:1 hondas running 5-9 psi.
thanks
