Hi all,
I just installed an SDS EM-3E on a newly rebuilt (never started) T-16
engine. (this project started looong ago...) After a few delays and
mishaps I got the magnets/sensor installed on the flywheel. If I turn
the flywheel by hand, I get MAGNET SEEN response for both magnets.
When the big moment arrived I cranked her up and she runs *very, very*
rough. The whole car shakes, occasionally backfires, occasionally
spurts smoke out the throttle body.
For now, I'm running w/o the turbo : throttle body exposed to air.
I've got the MAP sensor plumbed to the intake manifold, any extra
holes in manifold are plugged up.
With the accelerator partway down, the engine will keep "running"
until I let off the pedal. The fact that it will run for several
minutes suggests that the STARTUP values are *not* the culprit.
I've tried tweaking the MAGNET POSITION parameter over the range 75-85
and don't feel any real change (I placed the magnets to pass the
sensor 80 degrees *before* the flywheel is at TDC mark : that's
correct, no ?)
I've tried the turning the adjustment knob over the full range, and
even though it gets worse at extreme positions, it dosen't improve much
in between. I've got a 3 bar FPR and stock injectors (which I
reported as 24 #), and SDS provided a default map for these
parameters. Even so, the knob adjusts fuel values over a pretty broad
range.
Q : Is it risky to run the engine in this condition ? I don't want
to toast my (brand new) cat. conv. Or worse...
Q : Any suggestions on what to try ?
Thanks,
Jeff
