gear ratio change? what transmission do you have? Stock transmission with 4.4 final gear. Max speed 220km/h @ 8500rpm
I have a transmission with KAAZ 4.9 final gear and Carbonetics 1-5 gears for racing. Max speed 170km/h @ 8500rpm
The car worked perfectly about 5 years. I don't wont changing ...

Are you always racing your car? I never reach 5k rpm when I drive unless I'm either racing; or accelerating to pass somone. No. It's my everyday car. What a problem for 5k? I have vtec point at 6800rpm and rev.limit at 9000rpm. And driving my car more than 100ml/h at highway for a long time. It's a ...

This is normal behavior. What makes you think it is not? It's my normal cruising speed and rpm. I driving my car everyday more than 5000rpm for a long time. What a difference between 3000rpm or 6000rpm to forced open loop? Why I can change maximum MAP/TPS and can't change max rpm for this???
I ...

WHY???????
It's not normal!

B16A2
P30 ECU
Skunk2Stage2 Cams
LC1, narrowband connected to D14, wideband connected to D12
Symptoms affected with narrowband closed loop and wideband closed loop
When >5000rpm - s.trim=0

SManager 1.4.7.0 and 1.4.8.0
Why S300 switching to open loop from 5000rpm with any MAP and TPS values?

Maybe new algorithm will good work with stock narrowband sensor. But wideband sensor have a bigger lag time. And new algorithm have very optimistic fast rate of change short trim.
I set slow rate to 2% per second and fast rate to 4% per second. AFR not fast to adapt now but smoother and without ...

What wideband you are using? LC-1?
Did you used narrowband output for closed loop before, when you haven't problem? And switch to wideband closed loop mode?

Are you talking that you put the minimum short term adjustment from -30% to 0? Yes.
minimum AND maximum short term adjustment set to 0% and than tune.
You can select all sells in fuel tables and add about 30 values (not percents) to every sell when you switch to closed loop. It will be a little ...

Exactly. You have a problem at Closed loop with new version of SManager. But topicstarter have DIFFERENT problem!

just made a thread a couple days ago as well...

You have another problem. Tsuchinoko have problem with different AFR between Closed and Open loop.

I have this problem too. And I was posting this problem a lot of time ago.
This issue has not all ECUs. This is not at some ECUs.
When switching to Closed loop - AFR go to learn.
In Crome was option - "debug mode". When switch this option ON, than Open loop and Closed loop has same AFR. This option ...

Output from UEGO has 5 program of signal. Do you set output to P0 or P1?

1. Try to exchange pins from CKP sensor.
2. Try to exchange pins from CYP and TDC sensors together.

I tried this.

It seems this was not a good idea. I switched the pins back and now the car stalls and runs bad.

Could this joke ruined something? Tried what exactly? And what errors were there ...
