Standard maps within KManager have the Closed Loop threshold set to 80kPa.
I read one of Hondata's posts stating 70kPa is a better option.

I'm curious to see what others have set theirs to including a little insight from the moderators.

The reason for this is because I feel the car will enter Open Loop with what seems like little load on the engine.


Cheers,

I find that 80-85 kPa works well.

Personally I just run open loop :)

Thanks,
I've bumped it up to 80 for now, I'll see how I get on and report back.

Would a map of 90 kpa be too high for the closed loop max?

My main concern is that we need to tune for a richer mixture as the manifold pressure increases. As the pressure goes up, we want to tune the AF ratio closer to 13.0-13.5 for the NA tables.

So at what point do we need to tune towards 13.0-13.5 instead of 14.7?
How much pressure is the max that is safe to run at an AF ratio of 14.7?

If you pull enough ignition out of it, you can go as high as you want at 14.7 - you're going to be losing a fair amount of power though. Personally, if you're going to use closed loop, I'd say go with what Hondata recommends for the max load setting.

What is the actual max MAP value for closed loop? Does it switch to open loop at some point regardless of what value you put in there?
