Anyone play with the ignition auto tuning yet?

I did for a tiny bit before the engine blew. With both fuel and spark autotunes on the car would be weird as hell, idle would be all sorts of crazy. With this engine I have a super solid ignition map and won't even bother touching it without det cans. Even then I'll tune it myself.

As cool as spark autotune sounds, I just don't trust it anymore til someone proves otherwise.

I would use it for off-boost tuning.
Did you use it for boost?

Can you tell it to only autotune <100 kPa?

Well you could manually set all the cells above 100kpa to "already learned". So yea

The careful thing with autotuning is being responsible with it. It does mess around with idle because its constantly varying the ignition timing to optimize the torque. Tuning cruise with it though would be a really good use for it. MAP, TPS, and other variables are fairly steady so i think you would get excellent results.

So how would you set it up to tune ignition during cruise? Set all idle cells to tuned, then run with it? My fuel map is fairly well tuned below 5500 rpm and < 80 kpa...

This is for stock injectors and no boost yet...

Even if you set idle cells to tuned, the ignition autotune will cause you to have a weird idle when its on. No big deal, cause once its off it will be normal again.

Just set all ignition cells over 100kpa to "tuned" and turn it on to tune everything else.

Cool...

I think I'll save my current map first!

Thanks...

Bueller? Anyone?

Nobody datalogs with "always sense torque" on?

Where is this option you are referring to? I'd be curious to see someone's ignition map after an autotune...considering how wild the autotune values can get on the fuel map.

I can't believe there's this little interest in the coolest feature of the Adap.

I'm planning on using it once I get my exhaust fixed so it doesn't false trigger the knock sensor.

Could you try a quick datalog and see if you get a column called "advance metric" or "advance" ?

You can begin tuning off boost rows by first retarding your whole map by 2*, running "always sense torque", set ignition to "open loop", and then reading the datalogs, and manually advancing only off-boost cells, one degree at a time. Safe!!!

Its not in V2 either. Its in V1.12.

I'll try it as soon as I can get my car to change gears again.

Dammit, does this mean you can't tune timing with the Adap's nifty feature without letting it change your timing map for you, leading to possible destruction as 18psi above found ???????
