Coming from a piggy where boost and timing were fairly easy to understand, I now find myself staring at this and scratching my head on how to control boost and timing in a load based system.

Custom tuning of these tables will become an eventuality, so I am starting this thread to learn more about how to adjust parameters in a flash based platform.

+1 will definitely keep my eye on this thread to actually learn how to adjust things

Also interested to understand how to adjust psrameters. Just have to wait for my tablet to arrive to Sweden.

Without logging of all the cylinders, why would you be changing things? How will you know if your car is happy?

or this just to learn for when it is out?

Subscribed, very interested in learning.

Hi guys,
When I get a few moments to breathe, I'll make an other tutorial video that should be helpful to those who want to custom tune themselves

Starting with basic boost and timing control would be awesome

I managed to squeeze an extra 15hp over the OTS1 tune. Fueling was 10.4 on my motor and I leaned it up to 11.2 .

Problem I'm getting is timing on both maps drop to 4-6 degrees. I only managed to pull of 325hp in the end. Once we get proper tuning I will want to look into timing. This maybe knock related but I'm not getting any audible knock so not too sure.

From what I saw 11.2 is the AFR target in the fuel tables but my car gets into mid 10's as well.

Does feel a little rich.

in for an update on how to tweak the maps yourself

i have a procede i can use to datalog, in case the OF tablet datalogging isn't released this week

Here is what I believe to be one of the fuel tables for bank 1. There is an identical one for bank 2.

Looks like rpm is the y-axis and I beleive load values are across the top for the x-axis.

You can see that the majority of the table shows an AFR of 14:1 at low load.

But the table richens up to 11.2 at high load high rpm.

Bear in mind that I am only guessing here.

EDIT....confirmed via datalogging that this table can alter your AFR's.
My AFR's were running almost a full point richer than the targets in this table....adjusted the tagets up about 0.8 and I am now hitting low to mid 11's. Car feels less choked up top now.
