EGO is WAY too rich or not calibrated at all, or not present.

I have mounted the OEM small band because i´m switching from OEM ECU to FreeEms.
I will mount the LC-1 back if the FreeEms is running good.

why it does it shows aitor ?? :indiff:

Don't ask me! It's your log :-D If you were working closely with me, and using provided firmware s19s, it certainly wouldn't.

sadly IAT is correct :roll: while idle it sometimes rises up to 60-65°C and while driving it drops back to 30°C at this weather conditions (25°C outside).

This sounds like an MAT sensor, NOT an IAT sensor. If you read anything more than 0.5 *C away from ambient while at WOT above 2k RPM, something is very very wrong with your car. IE, it's magical. For the time being, you must connect an IAT (not an MAT) to your IAT input. If you do not have an IAT, that sucks, but fix the car. Where is your "IAT" mounted, exactly? Post a photo?

So that´s why i need a 3D idle valve pwm table :mrgreen:
and a idle spark advance table.

All in good time. You need to get the basics right first. VERY FAR from it at the moment. :-)

choose a fixed duty for the time being

what duty do you mean ?

Idle valve PWM duty cycle. Choose a value that will:

  • Not let the engine stall while cold after 10 or so seconds of manual intervention
  • Not rev excessively high once warm

Extend manual intervention to a longer period until you find a value that suits... :-p Fancy idle comes later. You have MUCH bigger problems than that. Even if YOU don't realise it.

Ahh, OK. That makes some sense. Is this your only car or something? You're never going to satisfy me enough without putting a wideband in for your logging sessions. Your tune could be miles off and no one would know. We make hard log-backed evidence based changes here. Arbitrary because someone wants something is not good enough. Need must be demostrated with hard data.

i have marked the Sensor ! for me it is a IAT because it sits between the air filter an throttle body !
Yes right at WOT the temperature drops to ambient temperature but i am not driving all the time at WOT :? LOL
If i´m driving in the city temperature easily rises to to 60°C !

Believe me there no such value for this engine !!!!
but i choose 39% duty @ 92Hz (M$-II values)

If i´m not driving with the M$-II i remove the LC-1 from the car because i don't want to wear out the LSU 4.2.
But if the car will idle without holding the throttle all the time and rpm can go higher than 3500rpm i will put the LC-1 and make a proper log ! i promise :mrgreen:

If the 60-2 decoder will be able to Rev over 4000rpm and some basic idle code is implemented i will proof with hard data !

update..

got the idle valve running with basic pwm warmup code.
engine is still not reving over ~2000rpm.

will add a vid the next days.

Congratulations on being the first person to actually use PWM idle! :-)

I've got three independent things in the pipeline that will help your RPM issues. Super busy at home right now, though. Doing the best that I can.

Looking forward to watching your video.

Fred.

Fred, when do you want to release the code with table based idle ?
For me it is working ...

Have remained super busy with new job and new house and new car(s) and fixing the ute, etc. The code I sent you works, but not in the way we want it to, and no one could understand why so far. Typically code gets released when it works properly and is complete. That code only works in a non-proper way. Apologies for delays. i'm getting closer to my keyboard every day. Should be on the job early next week, I'd say.
