Hej All,
Has anyone got a sparktable suitable ( 12x12 ) for my 2.0 zvh engine on efi..
Should be for 0-6500 rpm and about 0-200 kpa ( 14 psi )
I'm having some bad misfires above 5000 rpm so hopefully anyone has a basic sparktable for me to work from..
Thanks

You could try something like this... figures for each corner of the table..
9---14
| .. |
18--30
.. and fill in the gaps (interpolate smoothly).. assuming the top line is 200kpa..

Well, tried several tables but it doesn't go above 5300 rpm.
After that it sputters and doesn't revv any higher like it's going in the revv limit, wich is set at 6600 at the moment...
should be another problem then

Plugs are ngk with standard gap.
Same one as i had with mfi just new, worked fine for it then @ 12 psi
Boost is 200 kpa ( 14 psi ) max for now but it doesn't matter what boost i run.
Had the same problem today with about 150 kpa ( 7 psi ) at 5300 rpm.
It would be great if you had a look at my msq, thanks.

Are you using a 36-1 or 62-2 trigger wheel by any chance?
If so, it sounds like your VR snesor to wheel clearance may be a bit big - try decreasing the gap. I know the EDIS manuals say <1mm but it really needs to be less than 0.5mm on an MS install.
Also, how many turns do you have on your VR pots?

Tried to set the vr pots at any way but didn't work.
The ZVH has been converted to Full zetec turbo now and i'm mapping it at the moment.
Still issues with revs but when i rev it in neutral it goes well above 6000 rpm without problems so have to finetune it a little

Turn the VR pots fully anticlockwise and make the VR sensor gap to 0.5mm or less.

Turned the pots all arround at the time... thing is... when it's in neutral it revs above 6000 nicely.

I'll post a data log along with my msq asap.
Did a run today but on two ocasions th injectors were closed fully but you'll see it in the msq.
Also it's far to rich on boost... well anyway, i'll post it tonight.
Would be great if you would have a look at it.

I've put the sensor a little bit closer and it seems to be working..
Peak rpm wich i've had is 6885 and gets over 6500 easy.
Thanks.
Although i stil don't quite understand why it was reving enough standing and not driving, but no complaints as it's working now.
