After getting the engine to run, I now want to optimize it a bit. It starts rather difficult, and yesterday it refused at all. Fuel and spark are there, so the settings must be the problem.
I did notice the airtemp is a lot higher then it should be, I guess I might have the wrong sensor (though it came with this one???) Does anybody know what the temperature rate should be on these? VDO sensors come in several versions: 0-120°C and 0-150°C being the most common. Which one is needed? The manual states order numbers only, but these differ overhere (Europe) making it very difficult to find out what I need.
Anyway, this seems only a problem on starting, once it runs, it was running rather smooth (although at 1600rpm??? cold start enrichement?)
Any tips to make starting easier? Any settings that might be wrong (if so, what do you guys recommend?)

What are your CRANK FUEL RATE, INIT CRANK FUEL, POST START ENRICHMENT, and COLD ENRICHMENT settings?

 

I copied the parameters someone had posted on the forum, they are like this:
crank fuel: 10.07
init crank fuel: 11.32
post start enrichement: 26
cold enrichement: 29

My hand controller only increases in in certain steps, so some of my settings are as close I could get them. In other words, 10.07 became 10.

I have no idea if these parameters are good or not, I just used them since the seem to work on someone else's engine...

 

You can get air temp mapping data from the wolf website under the support menu. But you need a laptop to set this up! I had to reset my water tempreature sensor settings as it was reading 30 deg high. When you set up your idle make a little dip in timing around your idle speed and load this has the effect of adding feeback. As the engine slows it adds timing and tends to pick engine speed.

As a comparison, my CRANK FUEL is 4.67. For the Crank Fuel, you want the minimum amount of fuel to get the car to fire up. I would drop it down much lower, crank the engine, and keep upping the value slightly until it starts.

Also, its better to have the CRANK INGNITION TIMING a little more advanced. I'm cranking my car at 15.5 deg. Helps it turn over faster.

Enrichment settings are similar to mine.

 

I kinda thought so. My plugs get wet so I thought it might be too rich. I'll see if I can fix that tomorrow, and have another try.
Ignition is another problem, I don't even know if the CAS is positioned right. Can someone tell me how it's done? How do you place it correctly?

 

I can't get on the Wolfsite right now...
Any idea of how it's done? I don't have a laptop myself, but several friends have, so it might not be so hard to have one of them help me out.

 

The problem with the V3 Wolf is that it won't do stock timing, which is 5*ATDC. The most retard it will do is, 0* BTDC. You can't use the stock timing marks (unless you want to mess with the IGN OFFSET). So, what I did is make a new timing mark.

We know the difference between the yellow mark (5 ATDC) and red mark (20 ATDC) is 15 degrees. I took a compass and measured out the distance. I then transcribed that distance from the yellow mark over to the right, to make a new 'white' mark. This is 10* BTDC.

Set the CRANK IGN TIMING to 10 degrees. Crank engine over with a timing light. Turn the CAS until the the pointer lines up with the white pulley mark. This ensures that your timing is zeroed. In other words the EMS sees the same timing as the engine.

 

aha... thanks, that was what I needed to hear
