High boost misfire VEMS and LS coils

[jade]

Looks wrong to me, But As Stated No Expert

This looks good to me

Dwell 5 ms

Duration 2 ms

I run BCPR7ES @ 0,5mm gap with no problems at all.

Hello Jade. So you mean setting Coil charge time at 5ms?

Another question: As you car see in the photo the Coil charge time map scale is high. Does that mean the charge time rises when on boost or am i wrong?

Not a Vems expert But here some info

Hy Marc thanks for your tip. I actually forgot i have one of those at work .
I will do some test's tomorrow and let you know.


Last year my car run perfect on a 0.6mm gap. Now i have set them at 0.5mm but still misfire. I don't think i should just regap them closer and drive it that way. I think there is something wrong.


Last year my car was perfect on this map so i only like to do this when all the coils/wires and plugs appear to by fine.

But by saying more charge to the coil you mean upping the time in Vemstune => Basetune => ignitionsettings => Ignition dwell settings => Coil charge time @ 13.2V ???
Its now set on 1.98ms whats the max i would use?

Tanks!

use a coil tester like this:



to isolate any possible weak coils or weak spark plug wires.

try to regap the tips a bit closer.

More charge to the coil

I have some problems with my car at the moment. I made a complete new loom for my VEMS. Engine runs nice like before only now i have misfires at high boost. Running around 1bar all is perfect but at 2,2bar i have problems. Running LS coils i got from EFIExpresses 3 years ago and new BKR8E-11 plugs gaped at .5mm or .020" . As far as i know all the coil wiring i did is good. If i remember right i used 1.5mm2 wires and a 20A fuse.


I made some log's and i noticed when looking at the individual-power the misfire occurs on cylinder 4 right?

Can someone pleas look at my log and see if there is something not right and i don't see?
