Brent, many thanks for the reply... Tonight I shall attempt the following, 1. Replace ground/earth wire for EDIS module and 'Jolt unit. One thought I had late last night (whilst awake at a stupid hour) was that I currently have the EDIS module and 'Jolt ECU grounded to the engine on a loop terminal,...

Also, I think I may try a fresh +12v supply to the coil tomorrow. Rather than using the existing one that also powers the MJLJ and the EDIS module. I suspect that my problems may be there somehow! :?

Matt, Do the problems center around a certain RPM range? Does the engine smooth out after you push past the problem RPM region? I've not 'pushed past' the problem yet, it's a fresh built engine so I don't want to over-rev it just yet as it's not even run in. It doesn't seem to clear though, there's...

'fraid not - the coil doesn't need explicit earthing...the centre pin is +12v and the outer pins are open circuited/connected to earth at the appropriate times by the EDIS module. Well, this is what I'd read (on here I think) and that's why I didn't initially fit a specific earth for the coil. It's...

Thanks for the reply, unfortunately the timing light recieving no signal coincides with a nice misfire on the engine, so I am pretty sure it's actually losing sparks.

But, your post has got me thinking if it's something to do with the coil not earthing correctly????

Re: Losing spark on 2 cylinders above 2k rpm

Do you really mean this - the problem was initially on cylinders 1 and 3 and by swapping the leads the problem appeared on cylinders 1 and 2? That sounds weird :( What timing is the strobe showing at idle to 2000rpm? Should be rock solid 10BTDC. Is it? No, the problem was initially on cylinders 1 a...

Sorry, MJLJr (Junior) The megajolt is connected to the EDIS module. I will disconnect MJ tomorrow and try again though. Basically, the problem is on the coil outputs. On coil A (cylinder 1 output) I am getting a fault. On Coil B (cylinder 3 output) I am getting a fault. I know the problem is not HT ...

Losing spark on 2 cylinders above 2k rpm

I've got a confusing situation occuring with my MJLJR installation. Spec: MJLJR V3, EDIS 4 coilpack and module, MAP setup, used on a BL Mini 1380, running 11.25:1 compression ratio. Everything installation wise works fine initially. On idle it sparks nicely on all four cylinders. I've got a problem ...

Yes, I found the problem to be that my EDIS 4 multiplug had corroded sockets on the coil output pins (amongst others) so a new multiplug from the breakers yard rectified the problem. My wiring was (surprisingly) correct first time. :o

Well, the VR sensor was actually marked with a '+' on one side. So I did indeed have to switch the two VR sensor - EDIS4 wires around.

But.................still no sparks, time to triple check my wiring (again) I think.

KLAS, I've borrowed this map to have a look at your settings, cheers. :wink: Hoping to get my 1380 running tonight. It's also on a 286cam, 1.5:1 roller rockers, vernier timing gear, but has a higher CR than standard (11:1) and will be running on UBER fuel with loads of additives. Also on 36mm inlets...

Thanks for the replies guys. Much appreciated

Can't wait to get this mini running, it's been a looong build :D

I'll post an update when I have tried switching the VR sensor wires over later on today!

hmmm, OK. I'll try that, but what are the risks of that causing a problem? I will give it a whirl tomorrow night. :D

Hmmm, hello Fikus (fellow TMF type). Nah, the SEN8D was apparently used on Fords too. The traditional Ford Fester one was something like a SEN8T IIRC, which is the longer nosed one with a right angled multiplug connection. The SEN8D is basically the same but with a shorter nose and a wire straight o...

Nearly, but not quite - no sparks

Hmmm, well, I thought I'd finished the installation of my MJLJ on my A+ engined mini. I've got a brand new Magnetti Marelli SEN8D VR sensor, I think my EDIS 4 module is OK (even checked with another spare one today), but I am not getting a spark at all. I've assumed that my wiring is dodgy, so I've ...
