Strange VE values needed in fuel table?


Recommended Posts

Hi i just started my engine with a base map with some changes.

But to get the engine running i had to lower the VE fuel table to low values like 8% 

In the base map the values was around 20% and the sparkplugs got wet fast.

The engine is a 4cyl 2016cc with big injectors 2200cc.

Lambda is a Link can lambda.

Today i started the engine and run to warm, i attach the log and my map.

My fuel settings is:


What can be the issue?

I want to resolve this issue before starting to tune the engine.

I suspect it will mostly be your fuel density setting is 1/10 of normal so ecu will be injecting 10X more fuel volume to get the correct mass.  I would also suggest changing fuel system type to MAP referenced if the engine has a typical regulator that tries to keep fuel pressure relative to manifold pressure.

Thanks Adam.

Will test that, i dont think that i have changed that setting. 

I had a look at the first versions of the map, and the oldest one did not have modelled as an option.

So after a firmware update this was the default value with a storm blue base map.

But i need to put on glasses, because i did look at that value and miss the extra 0.


Thanks again Danne.
