Transient ignition correction map

Transient ignition correction map
Anyone played around with the transient ignition settings in Eugene? I'm not really sure where to start with it as the X and Y axis values aren't even filled in in any of the base maps for the FD or any other car that they work with. Also makes me wonder if they've even implemented the functionality yet.
In general, I've read that it's good to apply some amount of transient ignition retard to 1) smooth out torque ramp on aggressive throttle application and 2) reduce the chance of knock as it's hard to get AE setup perfectly in all situations.

Banned. I got OWNED!!!
It's an incomplete, buggy software, but at least you're digging and asking the right questions.
Don't you just love all the GUI display issues?!

Ya, I agree, their software could def use some more debugging, but they're a small shop (prior to being bought out) so it's to be expected. Pretty impressive what Andy has done with limited resources (coming from another h/w / s/w engineer). Unfortunately they're not selling 100s of thousands of these ECUs so they can't hire a really flushed out team.
To be clear, it's not that the s/w is broken in the pics I posted above. You can double clip on the axis and fill in axis values and then after that, I assume, fill in the table values, but I'm not really sure what values to fill in for the Y axis since it wasn't pre-populated. The X axis (rpm) was the easy one to fill in.

Hi Dawggpie,
It works really well - I understand that couple specific members on this forum are ignorant and think they know everything but you just need to simply fill in the Y scaling and then you can play with the feature. Generally I use it coming off idle for a better transient condition but that is really the only area I use it in. The reason adaptronic does not have it filled in by default is most individuals do not use it and its simply not setup.
Shift + Y will give you access to the table editor to add the Y scaling. (scale it from 0-100)
Shift + X will give you access to the table editor to add the X scaling. (I advise only going up to 1500 or so)
Cheers,
Shawn Christenson

Thanks for the info Shawn. Do you think you can provide an example of what the table data would look like filled in? Ie how much ign retard would you apply? If the x axis is only filled in up to 1500 rpm does that mean it applies no adjustment above that or would it just apply the 1500rpm adjustment to any higher rpm? You don't see it necessary to apply any adjustment on higher rpm/load throttle applications?

I will say this I do no really use this feature much but it does really work well with low idle torque engines.

Ah interesting. That's a very different use case than I was thinking about, but that makes a lot of sense. I'll give that a try and see what the effect is. I am running close to 0 timing in the idle area.
The case I was thinking of was actually using the function to reduce torque on initial throttle input by adding some retard to smooth the transition. This would mostly be for around the cruise section of the map.
The other use case, which I got from the BRZ guys, was to use the transient retard to lessen the chance of pinging or detonation in case there's small span of lean condition on a major throttle input (aggressively changing gears at high rpm/load).
