Edit, GUI seems to work now for me with only a coupel of glitvhes, but, i have not yet connected to th ECU :D

Whats the score with the Megatune 2.25p3? It doesnt look like that, that is in the video linked above, and I cannot select and modify any more that one cell. And, there are no task buttons on the top right.
Are you see multiple cells editing video?

Im seeing the video, and I like it.

Is that version of MT actualy available?

gunni

Look in this thread for it.

You have to be meticulous with the mouse to be able to select.
After selecting the top right buttons show up

Good man :) You are right

:D Im useless lol :-[

Ok just upgraded, here is the MAT table after letting the car sit and idle for quite a bit,
I just kept EGO control as close to 100% as when the intake heated up the ego had to keep adding a little bit of fuel.
So by using the MAT table I was able to keep the EGO at 100%.

I also changed to 16x14 tables, I had to re do them from the old ones but that only took a little time.
Injection output and ignition output settings went missing, but that was a easy fix as well.



IÃ,´m also seeing that my intake is a super blistering HOT air intake.

Now we just need
MAT Ignition table to go with it.

In the MAT fuel table I think there should be a lambda gauge, is that hard to change?

This is really great with some examples on how to get this to work,

Nice to have something to take the place of the "fake airden low limit" at long last!  (remember to change it to a smaller number if you were using it...)

Does anyone know if this new MAT enrichment COMPLETELY takes the place of the old one based on ideal gas laws (that gave 100% fuel at 20C and reduced it above this) or is yet another multiplying factor in the fuelling calculation?

I can now add a calculator for this setting to my data analysis and setup program :)

gunni

DonÃ,´t use those settings though,
as IÃ,´m still using the fake air dense, as well as that is before I changed the inj open time and that changed the VE table alot,
and now itÃ,´s alot lower , will probably change when I take the fake air dense away.

Its a case of editing the vemsv3.ini file.  It makes sense that the lambda gauge should be on there.

gunni

Ahh thanks for that :)

IÃ,´ll have a gander at it and see what I can do with it.

I had a play, and the gauge is easily changed, by changing the gauge = matGauge value.

Which gauge you decide to use is up to you, but I think the EGO Correction gauge is a little better than just the lambda gauge, as that shows the actual correction.

Just a thought on this, would it not be easier for us humans, to keep the corrections all in a similar format where the Warmup correction is base line at 100%. At the moment it looks like the MAT corrections are baselined at 0%.

Just makes it easier as you wouldnt then get confused, one less thing to think about.

While Im here, For a while I have been wondering what the 'coolant' bins are for and how to work it. What does it actualy do?

dnb

I'm with you on keeping all of the corrections biassed to the same thing!  It's confusing at the moment as to which things are "no correction" at 0% and which are "no correction" at 100%.

Sprocket

Ok just one other thing.

Boost Control Alternate settings

Boost control target offset - what is this, what does it affect. (im looking at this as an N2O control ;) )

gunni

Some how I worded my post wrong, I was thinking more of the lines of having a lambda and or other gauges in the 2d VE table.
I like that format when tuning and not the 3d view.

right now I have to go in and out repeatedly
