Spiider,

How do you know these values?

Any idea how you can calculate the VVT angles?

I am trying to put together a .xml format for this ecu usinf ecuedit

[Spiider]

The VVT angle amount is equal to what you see below.

0x00 = 0 degrees
0x40 = 45 degrees
0x80 = 90 degrees

Everything I have learned from the ecu has been extracted from the rom and compared by tracing the paths from ecu pins through to the mcu and then looking up the instructions for that port/pin in the processor datasheet to see what they are doing. (The hard way, but I've given in to the fact that no matter what I do, it will always be done by the hardest way it could possibly be done.)

[west_minist]

Ok. Very much true. Now remembering my Microprocess course.

I tried setting up somes 3d maps and there seems to be a problem w/ horizontal info. I have to resolve this now.

Thanks

[west_minist]

Spiider,

Can you send/post .xml format for one of the 3d maps?

My load setting are all over the place.

[west_minist]

W/ the new version of EcuEdit, it seems that the map creations are going successful. I only have a problem w/ getting proper load variables.

[Spiider]

I did some expermenting with ecuedit, but couldn't save my xml with that version. The ah581 has some slightly different table sizes. I had to play with the lengths to get maps that looked correct.

I never did get xml sorted out for any ecu's, unfortunately its all hex to me.

[west_minist]

I have them now

Its a really nice tool. I am only having problem w/ some of the calculations now.

[west_minist]

This looks like closed loop settings, but 4800rpm, seems to high for that.

#2814E (rows = 12) - #28167. Others are include just after that.

So we could be looks @ air/fuel correction and maybe learning.

But I do not know what the other variables represent. aaaaahhhhhh.........

[Spiider]

Looks like you have a lot of it working in there.

So far all I have adjusted on my map is the 200km/hr limit, and some timing and some OL/CL stuff.

[west_minist]

ol/cl????

Where is that? In those same settings I found?

[Spiider]

No, I don't think you have it there.
Some of it is listed in the offsets I posted above.

[west_minist]

Sorry I did not post back, but I saw it there. Unfortunately, I didn't understand it.

I was hoping to see load, throttle and something else.

[west_minist]

No, I don't think you have it there.
Some of it is listed in the offsets I posted above.

My cl/ol does look right.

Did you change your own to something lower?

can you post the .xml for those settings?

[Spiider]

Did you get a chance to look at the various maps for VVT angles?

Especially the differences between JDM and USDM maps.

Interesting peak in the low load / middle rpm area don't you think?


Also, is it just me or is the S202 main ignition map not the smoothest ignition map you have ever seen? I'm thinking of trying out the main ignition map and ignition correction map in my car to see how it likes that smooth ign map.
