Found the problem

The jittery timing was being caused by the timing light getting confused by the waisted spark. The timing light I am using has an advance dial on it, when this dial is used the timing indicated by the marks on the crank pulley are incorrect. If the dial is set to zero then it works OK. I had initial...

Part Number

This is the part number in the UK, not sure if it will be recognised in NA.

Jittery Timing

I have recently built and fitted a Megajolt using a MAP sensor. When the timing marks are viewed, at idle, using a timing light and running EDIS only (no Megajolt connected) the timing is rock steady at 10degBTDC. With the Megajolt connected the timing mark tends to be jittery i.e. not steady any mo...

Looking Good

Hi Colin, Glad to hear the photos were of some help. How long do you think it will be before you have it all installed? I have done about 500 miles since fitting mine without any major problems. I sometimes have a slight hesitation when the accelerator is pressed but I am not sure whether this is a ...

Pinto powered Robin Hood on the road

Today my Robin Hood Series 3 made it onto the road with a self built Megajolt. The engine is a Ford 2lt SOHC Pinto with a Weber 32/36DGV carb. I am using the vacuum takeoff on the carb to feed the MAP sensor. The pressure readings I am getting are not what I expected, at idle about 100kPa and at FOT...

Works better now

Submitted by niduncan on Sat, 04/22/2006 - 20:00. I moved the vacuum pipe from the carb to a takeoff on the manifold and the car drives a lot better now, it is smoother and more responsive. Watching the runtime display shows that the MAP is 40kPa at idle and the tracker now moves down and to the rig...

Vacuum from manifold

Hi Colin,
I had not thought of connecting up to the original breather take off point, I currently have this blocked off. I shall try it tomorrow evening.

Vacuum Takeoff

I have discovered that on the Weber 32/36DGV the vacuum takoff is on the air side of the butterfly, hence at idle I am getting roughly atmospheric pressure (100kPa). I assume that most people take the vacuum from the inlet manifold which at idle will be 20-30kPa. I now understand why my readings are...

What MAP

I am using Matt Dearden's "Pinto 3D base 6k" map which I downloaded from http://www.cate1.co.uk/megajolt/mapping.php. This was for TPS but I replaced the TPS settings for pressure settings: 0 to 10 36 to 20 51 to 30 65 to 40 80 to 50 94 to 60 108 to 70 123 to 80 137 to 90 152 to 100 on the...

Serial Port

I have just built a Megajolt and I use a laptop with a usb to serial convertor. I had to change the assigned port of the adapter to COM1 to work with Brett's software. But I have found that the mjtuner_0.2.2.1260_preview is easier to use and also works fine with the convertor.

Screen Wiring

The <a href="http://picasso.org/mjlj/?q=node/606"> Installation Diagram </a> shows that the screening for the VR sensor and PIP/SAW are connected to pin 7 of the EDIS module AND TO EARTH. Reading the other forums indicates that pin 7 should not go to earth as it can stop the advance workin...
