I would start the engine first, if it's a MEFI 1you will need to increase the RPM to around 1600 before you put the jumper in. If it's MEFI2 ,3 or 4, you just start the engine and put the jumper in, the RPM will automatically increase. Then set the timing.

I have to disagree with this. Turning the distributor sets the base timing when in service mode. In normal operation the computer or ignition module controls the amount of advance.

You are correct if your talking about a MEFI (pre 2002) engine. I was referring to the later model ECM555 engines that do not get the ignition reference pulse from the distributor, they use a crank and cam sensor. So turning the distributor will not change the timing and there is no Service Mode on these systems.

Default Timing

So how do I tell what MEFI I have on a 1995 Baja caliber twlight with 350 mag? And in order to adjust advance timing I need a scan tool or no? What is the must I can advance timing too? Thanks for the help

For information on how use a test light instead of a LED to read trouble codes, see update of the first post in this thread.

Default code reader reads zero.

hi dave.

looks like you know a lot about efi's.

i made that tool that you explained us, but in my case with the engine off, just the key on, i have code 12.

my boat is a monterey 98 5.7 efi digital ignition, still misses and backfires on top speed, i already checked everything possible and changed, with no success.

should i plug the tool with the engine running? or buy a better scan tool to find the codes, or i dont have no codes and the problem gotta be something else?

thanks
