Hi all, hope everyone had a good Xmas.
I've had a quick search but im not sure if this has been asked before specifically.
I'm looking at running an ignition management setup on my Metro with my 1380 Turbo motor, not least to get shut of the dizzy etc and free up some valuable space. Most people are recommending me use Megajolt, so this will be the way I go.
Looking at the complete kits (379 therabouts) things like dizzy hole bungs and crank sensor brackets I can make at work, i can source a Ford coil pack, and EDIS 4 module, molex plugs, HT leads etc so I'd probably be using the 'tailor you own kit' option.
My questions lies with
1 crank sensors, are these also Ford items, if so are they a specific type?
2) MAP sensors, is the sensor actually in the Megajolt ecu, so just needs a vac pipe from the Manifold/plenum to an input in the ecu (a la Escort RS Turbo for eg) or does it need an actual separate map sensor unit, and if so what kind?

Thanks for your help 👍

when you buy megajolt you can choose either TPS or MAP versions. You'll just get the map one and it has the sensor inside and you just attach a vac line to the megajolt unit.

And the crank sensor is normally ford too, but i think in general they just have 2 pins on them so are easy to wire up if you had got one from some where else.

Perfect, so that eliminates the need for an external/separate map sensor. So all I should really need to buy is the ecu itself and the loom. Presumably it comes static timed/Base mapped that you then tweak to what you want?

if you unplug the EDIS then it runs at 10 degrees i think so should get the car running. If you search the web you can normally find a map that might be close to your engine spec. Then you can load that into the megajolt, but obvisouly it wont be perfect so will need some more RR time to perfect it.

When you get the edis, coilpack etc, they normally have a small tail of wire on and you just solder your loom onto that. There is diagrams on here of the pin outs and what they do. People mount the various different bits to suit their engine bay

Somewhere on here is a map that is basically the metro turbo dizzy advance curve on boost, and a NASP type curve off boost. It's a good starting point to create a more progressive curve, and will be a safe starting point.
