Megasquirt Mappings, for 1.7L engine Options

[bd1308]

I need this thing to have some baselines pretty quickly. Basically I really need this thing to be like a weekend project in order for me to get to work/school on a monday or something.

at least something is needed to get it to idle, I plan on using a WBo2 sensor to aid megatune to tune my engine, I also plan on first using 'fuel-only' function in MS for now, and then add spark using the hall effect system(or optical?) that VW actually employed for the vanagons.


any help would be appreicated, i'm still in building phases( collecting needed small parts, etc.) but would like some gameplan.

Is it easy enough to add spark after the unit is programmed?

The DB-25 connector on the MS is definitely the weak link in the wiring, but you can do it right. Potting the connector body with epoxy or some other sealant might not be a bad idea if you are worried about vibration. Just keep in mind that you might have to modify it someday down the road as new features are added to the MS, or you want to add ignition, or whatever.

I used a crimp style shell and crimp pins, but I didn't like the lack of strength of the crimps my crappy tool was making, so I went back and put a tiny amount of solder on each pin for some extra security. You have to be careful, because if you add too much solder the pins won't fit into the shell.
