Timing

[dangerous doug]

Basic issue I know but I'm getting nowhere

 

I have used a piston stop tool to find TDC and to my surprise both marks are evenly spaced between the TDC mark on the pulley. So I'm now struggling to see why I need so much advance on my spark settings

 

the guy who looked at it first "aligned" the triggerwheel and pulley TDC in megatune but it never ran right after he messed with it. From his adjustment I kept advancing until it detted(it never did) but I've  got to 30° and thought I should re evaluate.

 

im now using tuner studioMS which I find is a bit more user friendly and this is what my baisic spark settings look like

 

(forgive the phone photo, my laptop isn't connected to a network)

 

now he has set it with the FIXED ANGLE setting which is where I have kept going from but a read up on various timing posts suggests that I should be advancing TRIM ANGLE however when I do this it will not rev as nicely and the temp creeps up like it has severely retarded timing. 

 

The timing light is absolutly no help at the moment as I say, if I set it to 8° BTDC it doesn't want to run right. Is this because I should be setting TRIM and not FIXED ANGLE?

 

pic of the spark table if it helps

What kind of timing light do you have?

[dangerous doug]

It's an accuspark sp8000

I think that's a problem, with edis, or wasted spark, it will give all sorts of odd readings -yoi need a simple on with no adjustments via dials etc, then you can know where you are.

Then you/we can debug things better

Can digi readout effect the strobe? 

 

So am i advancing the timing in the right place? Should it be with trim or fixed?

I am still learning, but my Spark Settings are different to yours.

In 'Fixed angle' I have -10, so that it will work from the spark table. Then I used a strobe light to check the timing was correct compared to the reading on tunerstudio, then adjusted the 'Trim' until it matched. I have '1' in the trim angle as it was pretty much correct.

That's the way one you have a proper timing light, for sure

With EDIS

 

Set ENGINE TO TDC

SET Missing Tooth to VR Sensor, 

THEN Rotate clockwise so VR sensor is on 5th Tooth

 

THATS then set correctly at +50 for EDIS.

 

At TDC its 50 degrees out !

That make sense ????

Rotate the trigger wheel or entire pulley? I have set it almost perfectly to the 5th tooth while the pulpy is at tdc to its factory(correct) marks
