The sensor used withing the Ford Map sensor (from a normally aspirated Fiesta XR2) is "MPX4101A" and from looking at the data sheet, it won't be suitable...

It was worth a try though.

When I got all my EDIS stuff from the local breakers yard, I got it all from a 1990 Fiesta XR2. I just grabbed the whole lot, which included the factory fitted MAP sensor. I decided to open up this map sensor, and inside there is a PCNB fitted with a PIC and a similar map sensor chip. The only probl...

I may be onto something that may save us UK peeps a bit of money... it involves a small amount of effort, but if I am correct, you may well be able to get a map sensor chip for circa £3 sterling... ok... it won't be new at that price, but it may be an option for those struggling to get / afford the...

and it will run off the contact breakers etc. I'll have to see how small a signal it will actually work from. As you say... i'll just have to try it... Shouldn't be too difficult to build a small amplifier module to up the power from the tacho output though.

Cheers for the quick replies.

So I could use this function with a rely to cut the power to coil pack as a "hard" rev limit...

My learning curve is quite steep at the moment.

Is there not a function in the tuning software to alter this? I havn't got up and running yet and I'm still learning myself, but in the tuning software I have, it has a rev limit setting under the "programmable outputs" tab. I'm currently fitting MJLJ V3 to my Capri (2.1 pinto). What map are you run...

Do you think the tacho output on the V3 board will be up to triggering 2 tachometers? In the Capri I have the O.E tacho and one I designed and made at home. <img src="http://www.ford-capri.fsnet.co.uk/whiterose/images/rev_counter.jpg" /> I have tested this digital one at work and it'll still run off...

I made my own by buying 2 suitable D types and then just used some old telephone extension 4 core cable... wired the 3 pins needed direct pin to pin and it just works...

Yes Brent, i will probably be doing something like that eventually. As the bracket is ally, I'll have to either bolt something across it or have it tig welded... we do tig at work, but ours is for stainless and isn't AC... I think there is a local guy who has an AC tig machine... EDIT: made up a tri...

The MK2 facelift Capri, commonly referred to as the MK3 Capri wasn't exported to the US... it was just a Europe model. The body is the same as the 74 to 78 Capri that you would have got over there and will take a 302... a mate of mine is doing a 302 conversion on his Capri at the moment. My other on...

Looking at later in theyear I think... I'm going to use your idea with the cut down distributer casing too as I want to retain the layout of the plug leads. I have a lot of fettling to do yet, but I'm hoping to have the whole lot up and running during the summer. I'm busy rebuilding my 2.8i Turbo Ca...

My MJLJ controller is built and seems to be working fine... managed to upload a map to it using 4600's tuner software and it is reading 102kPa on the bench... Now onto the mechanical bit. I've got the bracketing sorted to mount the VR sensor, and it is fully adjustable to get the timing spot on. Tha...

I have built my V3 controller and all seems well... it comunicates with mjtuner_0.2.2.160_preview and I have been able to upload a map to it ok. My question is this... just sat on the bench, the map reading ia 102kPa as expected... now... I fitted some tube to the map sensor and sucked... I was able...

Does the VR sensor have to come from the same car that you get the EDIS4 from? I have got 2 VR sensors and they have different resistances. I understood that it doesn't really matter... if it does, I'll have to get the one from the XR2 that I got the edis unit from...

on the 32/36DGAV and the 38DGAS... but only by a couple of millimeters or so... the reason for this is the original vacuum advance mechanism is not supposed to see any vacuum at idle, but when running at higher revs there is vacuum there at light and closed throttle conditions. I have measured the v...
