So I got my Tiger started last night... The BossEFI looks like it will be a
good thing especially if the self-learning tuning works as it's supposed to. I
appear to have a timing glitch but that may be due to the way I wired the
distributor. Because the computer can supposedly compute its own timing
advance curve, and I'm using the MSD to actually drive the plugs, I eliminated
the often troublesome TFI module from the Ford distributor and wired the Hall
sensor (PIP module in Ford-speak) direct to the computer - you only need a
pull-up resistor to make that work.
The only bad thing is that it's got a fairly noticeable knock, that I'm sure
the engine didn't have when it was last run about six years ago. Is there
anything in particular that afflicts the 5.0 roller-cam engines when they've
sat for a long time? As far as I know nothing fell in any of the ports in the
interim... when I swapped the engine into the Tiger I put on the cast 'Cobra'
covers and the Canton windage tray and oil pan, but with stock 5.0 valve train
I wasn't expecting any interference issues. The engine turned over by hand
without any noticeable tight spots.
Any ideas or suggestions would be most welcome.
Theo
