High/low octane spark tables interpolation factor

[The1]

Yeh im having a look at what's possible at the moment.

Looking in the code the adaptive spark is in the knock attack rate code, so retarding from hi to low can be less aggressive than taking timing out via knock which would also have a slower recovery.

Attached is the options available for example in factory form in a VT L67.

The minimum cylair amount before it can attempt to use the high octane table.
RPM Points between where it will try to use Hi Octane
Timing differences between hi/low before it try to use or allow hi table
amount of knock retard before it will move back towards the low table and the rate to move towards the low table.
there is also a scalar to specify the return rate back to hi oct table.

So in a nutshell it's taking over between loops to try and avoid full knock retard and give you a bit of play room, like a safety margin, so you still want to tune to avoid knock obviously.

Not sure if that question is pointed at me... responding as if not.

I don't know how it all works I just know there was 1 actual percentage RAM reference that referred the tuner to know where knock was being affected & where it wasn't as there was a percentage table that it worked off to know what table to tend towards.

I know it took 3 times as long for it to loose the higher percentage value than what it took for it to learn it?

no just the thread.

Found an issue and fixed it all up, have tested on bench quickly before i head off and all seems to work, am able to easily add in adaptive spark retard in Degrees to the datastream.

Spark Via adaptive spark ramps down to the low table correctly when out of range.

Will add the feature into the Enhanced mod, testers should see it soon.

Thanks for adding the feature The1!
Well I've got the latest adx, and xdf in tp5 as well as the latest bin file on my nvram. Now ive added the adaptive spark retard value to the montiors in your adx file. Im getting alot of knock retard without registering any knock. Also im not sure why but the adaptive spark value doesnt move at all it stays at 0?

The changes i made are adjustments to injector rate multiplier but also increased spark advance in the hi octane table by 1deg across the board as values were set equal to the low octane values... that was my starting point

As above it needs a minimum of 3 degrees between tables to work.

my bad..

i had only had it in the pic and didn't explain it so that's my fault lol
