[Diy_efi] Project underway...
Sat Sep 1 17:45:15 UTC 2007
I'm working on a project with a friend, converting a 1940's Ford 255CID
flathead V8 from carb and points to a TBI/ 1227747 setup. The electronics
hardware side is done. The engine has an afermarket distributor with a
conventional VR pickup coil. This is connected to a standard HEI module
that is firing an MSD box. In the pictures the advance weights are still
present, but they have been removed and the advance bolted so the ECM can
control the timing.
Here's where I want you guys' thoughts. The intake manifold has a huge
plenum, look at pictures linked at bottom. We're using a 4.3V6 throttle body
and injectors. Do you think the injectors flow enough for accel enrich to
keep from bogging when you open it? It is a very mismatched setup on the
engine/ cam/ manifold but this is what we have to work with.
We'll be using Cats RT Tuner and a wideband to adjust the VE tables. This
has been a fun project so far, but the real fun will be making it run
correctly. It will be an open-loop calibration, tuned for drivability first,
power second. Any thoughts?
Thanks in advance,
