Have hesitation after throttle. Don’t really understand datalog on kpro is this normal

It's starving for Fuel if your afr readings are correct. Had it been tuned yet?

Just got my kpro in and calibrated closes to the engine I have. New to all this and don’t know how to read it. So fuel starvation? I set my fuel pressure regulator at 50psi

What should the af reading be at

 

[Bjorn]

At warm idle, 14.7:1. When you stab it, Id expect to see it around 12.5:1 you will get some fluctuations with rapid throttle changes but that's a general target

 

[Bjorn]

What should the af reading be at

You need to get it tuned.

map from an other car with “close” specifications won’t be enough.
It is either so much off it won’t even hit an AFR of 14.7 in closed loop or it still runs open loop.
Get it mapped or lear how to do it.

 

[Brotatochip]

In parameters, fuel trim, add 20% fuel to the overall fuel trim option to make it a bit healthier for now. But yeah, it needs tuned.

What engine do you have and what calibration did you use?

Dc5 k20a using the k20typer kal toda header ect.

Should I disable open loop

It should be tuned properly first. This is by far too lean if the wideband reads correct and the header is leak-free. After tuning you can setup the closed loop active. So check out if the header is sealed fine and the wideband-header-interface too. If air is inducted into the header by an leaking location of it, the wideband will read wrong and the closed loop controller may get unstable or into oscillation.

I’ll check the header and see if there is any leaks
