ECMlink Critique my SD!

So I am in the process of tuning on SD, mods in sig. How does everything look?

See values that high in the SD tables tells me your global % needs to be adjusted, and then scale the SD table for it.

You could also use a bit of smoothing as I see jumps of over 10 from cell to cell.

You can also tell it's off a bit when comparing the AFRatioEst and wideband lines.

I'd also recommend using just the DA tables for adjustments and not the sliders (i.e timing sliders).


Overall it looks fairly well as long as you smooth it out a bit and adjust global to be able to scale down the SD table. But the lines are close and you're on the right path.

Ill smooth a bit more and get back on that. As for the injectors, I dialed them in where the car likes it. Any lower and I have high cells.

As for the timing sliders, I am using them as a temporary adjustment, as I am learning what the car likes, once I find it, I will use the DA table to adjust it.

If you play with calan's LinkTools program, you can see how changing global % will affect the scaling of your SD table. That's really all that should change, and seeing as you account for it when you scale it, you won't notice anything odd/off.

Tried fiddling with that, but it does not work well with office 2010 :/. Anywho, ill adjust the cells a bit more and lower the timing 2 more degree's to see if I can get rid of that knock. Then add some more boost/meth hopefully.

It works well enough to be able to use the scaling feature. I just played with it and scaled the table using -39% global and I'm seeing the highest numbers around 103 which looks much better. But play with it and see what you come up with.

But isn't that technically a "band-aid" fix to lower sd cells? I mean I don't think my cell's are terribly high personally.

Also to add on the cell smoothing, are you talking about the cells used for cruising? They have to be that low in order to get the combinedft in close to 0, so should I just work around that, or?

 

[snowborder714]

I wouldn't necessarily say it's a bandaid, as you aren't covering anything up. But more just an adjustment.

The cells I was looking at for smoothing are around 2500-3500 RPM and 11-16.5.

Judging from your VE table and the relatively low amount of AFR error, I would say you definitely have something incorrect with either the fuel values, or an incorrect MAP sensor input.

Based on the low VE values at low loads/RPM, and the high values at higher loads/RPM, I would say both your global fuel value and injector deadtimes need some more work.

I have a set of new injectors on the way, and will play with it a bit more with them and repost a new log.
