MJ - feels like ignition timings needs more advance!!
Turbo Mini Forums

Finally got the mini finished today, and had my first test run! :)

There's a few things I notice which don't make sense!

Firstly when I frist started it, it seemed to be missing on one cylinder (NO.4). I check the lead position on here and they were correct from what I read.

http://www.turbominis.co.uk/forums/index.php?p=vt&tid=9655
But when I look at the ford firing order it said that it was


1243 so a put the leads

mini--------coil
1-------------1
3-------------2
4-------------4
2-------------3

This seemed to run spot on, but it sounds like its different to everyone elses setup? any ideas if its correct?

Something I notice when I was driving was that there seemed to be a big deley from when I put my foot down to when the engine picks up, and occasional it would jolt and completely misfire. All the symptoms remind me of when my timing was too retarded when I was using a Dizzy. Not sure whether this is to do with the HT lead setup or the MAP. The map im using is the standard turbo one supplied with the unit?

Also is it normal to have a bit of clutch judder with a new clutch plate?

Sorry for the long questions, any ideas would be appreciated.

Matt

There are 2 coils in the coil pack one fires on cyl 1 & 4 and the other on cyl 2 & 3. Interchanging the leads between 1 & 4 or 2 & 3 will make no differance.

As for the retarded ignition have you had a timing gun on the pully to make sure that the MJ is changing the ignition advance correctly?

A man without a project is like a like a woman without a shopping list.

With the wasted spark coil pack 1&4 fire at the same time as do 2&3 so I wouldn't have though swapping the leads around would make any difference. Perhaps one of the leads wasn't fully pulled in and swapping them over sorted it? but that's just a guess.

Also to address the throttle response you might want to increase the advance a little at low rpm & low pressure and see if that helps. Bare in mind there could be a couple of degrees error in the location of the crank sensor, which would cause the whole map to be slightly retarded.

post your map up and lets have a look

Yeah I thought it fired in pairs, thats why It seemed odd when it made a difference, you could be right about the loose lead Rob, i'll swap them back and see what happens.

Not tried a timing gun yet, haven't got easy access to one at the moment.

I'll try post the map.

Does the MJ unit need a 12V supply to read the map off it?

i beleive it does need power to talk to the pc, but a 9v battery will suffice (i think...?)

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

9V works fine!

New clutches can judder a little. More so if all friction surfaces werent 100% flat when re-built ( ie flywheel and cover )

When checking ign timing with the MJ, does it read like a lot of wasted spark systems ??

ie 20 deg on timing light, will be 10deg actual timing
40 deg on timing light, will be 20 deg actual timing...

I know my ecu does this as its a wasted spark system in effect with only a crank trigger.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

matty, if you have no map installed (unlikely i know) or something is amiss ecu wise (again unlikely i know), could edis be operating in the default 10 degree advance-get you home-safety setting?

i would think it would be a bit of a dog if so?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

If the MJ is connected it will be running what ever map is in there... EDIS only defaults to limp home mode if the ECU fails to respond.

Some people do supply MJs with out a starter map - so in theory you could have ZERO degrees advance!

If you haven't got a timing light to hand a good check to see if the MJ is working is to get the car ticking over and then put in a big change in the map. The engine should react. I.e. increase the advance and the engine should pickup, retard and it should slow down, in general anyway. If this is not happening then I would suspect that the EDIS is at is 10degrees fixed.

matty let me know if you manage to figure whats causing yours to jolt and misfire. Mine does it like a goodun usually just as its coming on boost, it'll stutter a bit then it'll just jolt really bad like all the power to the engines been cut and then go again.

I can't decide if its leaning out as it comes on boost or if the coil packs breaking down. Need to try and find out before it goes to the rollers really though.

Bud I seem to remember something about wiring to the coil that can cause those symptoms!

I'll see if I can remember more about it!

cheers alex, i'll grab you on msn or something rather than spamming up matty's thread.

Might be useful info though ...

Every day is a school day ...........

How fast and how expensive ...... the same question...

Bud it does exactly, as you say It would be handy to know what the outcome is with yours!

Stevie the flywheel is the same as I had before, the friction plate and diaphragm have both been changed, I guess they'll bed in eventually won't they?

I'll have a look tomorrow night with the MJ plugged into the car, see if its actually got a map at all!

Cheers for your suggestions lads.

Right plugged it in with it in the car, and I can't seem to find the MJ unit at all.

I assume to find the Map you just go, FILE>OPEN>then the list of devices should come up one being COM 1 with the meagjolt in?

The port its pugged into has the symbol
|0|0| above it, its the only one it fitted into?

I had a look at nic's installation guide where it mentions about renaming the port to maybe cure communication problems, but whatever I try I can't seem to get an option anywhere to rename it?

It should find the device when I go through 'my computer' shouldn't it?

Like USB devices show as 'removable E or F' etc?

Bugger, hit the wrong button and lost my reply, let try again.

I've never looked for MJ in my computer, and I wouldn't expect to see it there to be honest although I've not tried (unfortunately I've lent my MJ to another member of this site, so I can't check at the moment).

Normally you can see if MJ is connected by going into the configuration software, and trying to write a map to it, if MJ is not connected (or not working) the "Commit Configuration to Flash" button will be grey out no matter what you try and do.

Finally to select which comm port your using in the Configuration Software select Tool / Options and it will give you a choice.

AlexF

to read what the MJ has in it you need to ckick GET CONFIG.

Ah right, I clicked on the GET CONFIG, and it said that there were no maps loaded, but it would say that if it wasn't finding the MJ anyway wouldn't it?

Ah just plugged something else in the COM1 port and found it in NETWORK CONNECTIONS, I'll plug the MJ back in and try and find it there!

Rob I did try a few different ports in the OPTIONS tab, but then decided to look another way, as I had no luck!

At least I've got a few more things to try now! All fun and games. Lol

Matty, I have Rob's MJ to play with. I'll try to boot it up tonight but as I don't have a harness yet that might be a problem.

If I can I'll post how to find the maps, sure it's not going to appear in the drives list .... it's not like a USB data stick.
