Re: Computer chip for 1990 200TQ
I hear that the intercooler is already large and efficient.
An even larger one might not be a good HP/$ investment.
There are Microfulers for 5-cyliner engines. I have one
on my Ur Quattro. You will need to improvise and/or do
a bit of fabrication to install the injector. I cut the
hose between the intercooler and the throttle body and
removed a 3" section. I then installed a injector mount
in a 2 1/2" pice of pipe and connected the assy into
the above intercooler-to-throttle body hose. The
Microfueler computer monitors boost and RPM and varies
fool delivery accordingly. It is tunable for RPM, boost
and RPM cut-off point. It only works when under boost so
drivability and emissions remain totally unaffected under
normal operation. I have yet to get mine tuned properly
since the K24 turbo upgrade. I have a leak in the above
mentioned hose that allows a small amount of boost pressure
to escape. Presently waiting on a new one from das
Fatherland. I don't want to inject any fool into the
system where it could escape into the engine compartment.
:( I'll post the results when I get it working again.
Also, you can use different size injectors to vary the
amount of enrichment. I also have a "spare" intake
manifold. If I get real brave I might try mounting
5 injectors directly into the intake manifold.....
after extrude-honing, of course. :)
