Absolutely. I'd like to see it implemented asap as well since it's really not that much work

Hire some new people to come out to CA and get this stuff rolling. I officially nominate myself as Logistics Operator so that your staff can focus on the product improvements you guys have been making. I bring experience and a Limited BRZ

What jamesm was talking about was for flkc, what we are seeing is fbkc.

Negative, he was talking about FBKC too.

Yes, I was referring to the IAM "fix" you were talking about.

We just ordered an Innovate LC-2 so the ball is rolling

Man, it never ends! Don't know what to spend money on anymore... Seems like you have something new every few weeks!

This isn't unique to Shiv's tunes at all, I would bet that if people were logging most canned tunes (and even lots of custom tunes) they'll find the exact same thing happening. I haven't pulled any logs on the stock tune, but I know I get knock on the stock tune occasionally on heel/toe downshifts on the throttle blip (clutch in, so no real load). I would imagine the same behavior would show up in logs on the stock tunes.

The "fix" for it is to change how the ignition tables are mapped out a bit.

You basically have to minimize (or zero out) the advance cells in certain rpm/load ranges and move all the ignition advance to the base timing table.

The final applied ignition advance is base timing + (IAM * advance timing).

The formula for figuring out if a knock event goes into fine or coarse (dropping IAM) correction is more complicated, but the only part that matters is that if the IAM * advance portion is under a certain value (2.9 or 3.9 IIRC?) it won't go into coarse correction and the IAM will stay up.

I call it a "fix" more than a real fix because you'll still get knock (which happens even with a LOW IAM, and even on e85), but it won't take out the IAM in the process.

Disclaimer, I haven't actually edited my own tune for this yet, just basing it off what other people have been experimenting with.
@jamesm posted a bunch of good information about this before being banned, and @nelsmar has posted a few times too IIRC.

If you look at some of my earlier posts i have fixed this issue of iam dropping i my car by small reduction in rpm/load advance cells in the ignition advance table, without resortiing to disabling course correction .

As far as I know, you can't disable coarse correction, but you can stop knock from affecting it by reducing the values in the advance cells so they're lower than a threshold (2.9 or 3.9 IIRC).

I would bet that what you did was reduce the values enough that it doesn't affect coarse correction at all?

jamesm's suggestion was to move the timing from the advance down to the base timing so that you don't change the overall timing (assuming an IAM of 1.0), but your method would definitely work to stop it from reducing IAM too. You may have lost the tiniest bit of power in that range, but I doubt it's noticeable.

Not getting knock is better than ignoring it just to see a 1.

When are we gonna see the 1.6 maps out?

nope thats not what I did see here

most of the values in the knock prone area are still above 3.9. Some were already below this threshold .

I specifically did not want to "effectively" disable coarse correction by moving all the timing to the base map or reducing values below 3.9.

The max retard amount was 0.35 of a degree.

I have used tactrix logging which can monitor fbck & flck at 20Hz and have logged noticeably less occurrences of both and the values are also less for fbck and flck in the knock prone areas with these changes.

I believe it the less knock severity and less occurrences that are resulting in the ECU not entering coarse correction mode and dropping IAM.

If your IAM is dropping to even to 0.7 then your pulling 30% of the timing values in the entire knock correction table for the entire rpm/load range which is going to result in retard amount somewhere from 1 to 3 degrees which is going to rob you of far more power than my 0.35 degree adjustments in a few cells I believe.

I am not saying this will work for everyone but its working for me on Aussie 100 RON fuel.will try on 98 next week.

Awesome. Does this mean we are that much closer to seeing you progress to the turbo? Someone needs to really hit the stock .bin file harder to find out how the WRX handles boost. I can only imagine there is a way to do it, otherwise other cars would not be so successful with RomRaider.

Hey gang,

I just got (and installed) my OFT this afternoon. Flashed stage 1, feels good - quite a bit sharper, a bit more eager to rev. Good news. Excited to get a header and run some E85.

When I connect it to the OF Manager on my PC I see that my OFT is running FW v. 1.24. Other than a new map format, is there a compelling reason for me to upgrade?

Thanks for your advice - there are so many "open flash xxx" threads going that I get lost sometimes. :-)
