Can megajolt do advance of less than 10 degrees

[molecular bob]

Can the cranking advance in cell 0,0 be set to less than the default 10 degrees of the EDIS system? or would i need to alter the position of the toothed wheel to allow a real 5 degrees, and alter the running advance table to compensate.

What is the permissible advance range that can be programed if the setup is running with the EDIS firing at 10 degrees when in limp home mode?

Hi,

The MJLJ allows you to set an advance of 0 - 59 actual degrees BTDC anywhere in the ignition map.

There is also a special behavior in the controller where, if the engine is at cranking RPM (below about 450 RPM), the controller fixes the ignition advance to whatever is specified in ignition cell 0,0 (lowest RPM / lowest load cell). and yes- this value is also configurable between 0 and 59 degrees BTDC.

Hope this helps,

Thanks Brent, covers all the ground.

I was just unsure of whether EDIS was designed to do advance of less than 10 degrees. As it will, i can set my cranking advance to 5 degrees and give my starter a bit of an easier time.

Hi,

where is the 0,0 cell for cranking advance? i cant seem to see it.

It's just the top left cell on the map....

[boostedmini]

the cell at the top of the load and to the left of the first rpm cell?

i cant add or change anything there....

It's one of the normally editable cells- it's the one at the lowest RPM bin and at the lowest load bin- nothing special.

oh silly me so it is a normal cell but the MJLJ looks at it to be the cranking cell?

thanks will play with that a little more then.
