For cvs it is not possible. In first version all log channels was written to cvs but files have size of gigabytes :)
And export takes hours on i7 computer :)
Please also corrct the view in log. If i select AFR its OK, but if selected lambda view it ends with line on top.........

Can you change the Boost DC ref table to RPM vs Boost Target (kpa) vs DC% and apply the Gear, VSS, IAT, and EGT scales to the boost target only?

As it is, 80% in one of the scale tables will take away 20% duty cycle and 20% boost target. This does not work out to give correct duty cycle for desired boost target. If we have 70%dc and 220kpa in the two tables at 100% throttle, 80% scaler would bring these down to 56%dc and 176kpa. This is 5% valve duty cycle off from what it should be with a target of 176kpa. This issue would be massive when using a 4-port valve.

I know the integral parameter will take care of the offset, but the issue is with the feedback limits we set in the PID and Error tables to avoid integrator wind up. In order to take care of the offset, we HAVE to set a large integral limit, which leads to a big problem with overshoot.

This should be changed to give us the proper duty cycle for the given boost target so we can set reasonable limits to feedback components. Apply the scalers to the boost target ONLY and use the ref table to give the proper dc% for that target.

Initial pulse and cranking injections do not get the injector cal time added. The battery may be weak or strong and we need the cal time added for consistent start fuel.

Knock Restore rate is too slow. Currently, setting this to 10 revs (fastest possible) will give around 0.5° restored per 10 revs. Can you change this so the full restoration of fuel and ignition is given over the 10 or 20 or 200 revs (whatever we set this to)?

Hi Kurt!

In the new software 1.066 there is option to activate battery correction for prime pulse and cranking fuel (Engine start / parameters).

For knock sensor action restore we change the restore rate minimum value to 1.
The name of this paramters can be misleading, and we are going to change this name in next release.

This parameter means after how many engine revolution when there is no knock the ignition retardation and fuel enrichment can be restored by minimal step of 0.5% / 0.5 deg.

Hi!

The abillity to change input on x and y-axis in fuel and ignition tables would be great.
I personally prefer rpm on x-axis and map on y-axis....

A programmable in and out angle from fuel cut option.
Now it's on /of whitout transfer time and you feel the big transistion in fuel mixture very hard when driving.

Changing axis for tables is possible. On the toolbar of 3D tables there is an icon with for properties.
There is option "Load on Y axis"

For rev limiter fuel cut you can use Ignition / soft rev limiter

Yes , i know but i mean the fuel cut in Fuelling. During normal driving. ;) It's very harsch off/on. On/off is not so harsch.

I tried , but i think that's only the cutting off angle not the coming back on . :?:
It's the coming back to normal fuel level that's giving a "shock".

Or you can use shift and 0 what´s in germany = is. Shift and - make -5.
Best regards,

In next version there will be option for redefining keys.
It helps with different keyboard layouts.

How does your VE map and timing map look? Are you sure the problem only lies with fuel cut? I normally set fuel cut to re-engage at an RPM above the point where I'd have issues with smoothness in traffic, then the rest can be done by tuning the lower load cells in the VE map.
