SAFC II Tuning Basic

[bountykilla0118]

I was wondering what would be the ideal throttle(TH Points) points to start tuning. I remember reading a thread where someone saying that was a good idea to tune from 75% throttle up.... I am asking because I don’t want it to run lean during the transition from cruising to WOT with boost.

I had the car tuned a while back but I cleared the settings trying to trouble shoot ssooo I zeroed everything.

So hopefully you guys can shed a little light about the basics of tuning. I have some sample SAFC settings and the results of the setting but that’s about it.

I was also wondering about what hi/low throttle points to use. I searched and found a couple different opinions, but I would like to get an expert opinion.

the open loop transition occurs around 75% throttle, so that's a good starting point...

not familiar with "open loop transition" but anyways, set the hi AND low points both at 75%?

Closed loop, regardless of any system is when it is responding to its own control. So for us, the ECU is reading the oxygen sensor and adjusting fuel with it.

Open loop is not.
