Chris,

I had no end of grief with my "93 mustang engine management and wiring,
to detail it all here would take pages.

Suffice to say that in the end I tossed the lot and installed a new engine loom and ECU from Massflo EFI. I already had their injection setup.

This promised to be a cure all......well, it wasn't quite but Chris Richards over there in the US supported the product well, tolerating lots of stupid questions and diagnosed many of my screw ups with patience.

This guy really knows engine management.

The car runs really well now.

Anyway, I see that you are persuing fixing the old A9L, if that doesn't work out PM me and I'll tell you more of the story
