Lambse.. Explain
 

Ok.

On Calcon what exactly is Lambse? I thought it was what the EEC is actually commanding based off the info in the Closed Loop or Open Loop fuel tables?

Am I wrong?

Re: Lambse.. Explain
 

You are correct. It is the commanded AFR. It is already compensated for the adaptive info in the KAMRFs

Re: Lambse.. Explain
 

Why would someone see 18:1 Lambse then? Spoke with a member tonight who is working some bugs out of his car and he said that his Lambse was hitting up to 18:x at idle

Re: Lambse.. Explain
 

Is his adaptive on? I would guess that his MAF may be so far off that the short-term fuel trims are causing it to comand that ratio. :shrug:

Re: Lambse.. Explain
 

I believe adaptive is off. Is there a table that would command such a lean a/f.

Isn't Lambse based off the info you put in either stablized CL and open CL? (What you see is what you command?

Re: Lambse.. Explain
 

I'll wager that adaptive isn't off, or Lambse wouldn't be commanding 18:1. Remember, 14.7 is what the EEC wants at all times. In fact, 14.7 is actually hardwired into the EEC and isnt' changable.

I really have to say that adaptive isn't off at the point where it is commanding 18:1, especially if it is at idle.

Re: Lambse.. Explain
 

?? Are you sure? How could you command rich a/f for a combination such as mine without changing it in the fuel tables. That is the only way you would be able to tune your MAF and it have the correct curve.

Re: Lambse.. Explain
 

There are ranges for adaptive KAMRF and there are ranges for LAMBSE. If you look at the stock ranges for LAMBSE are:

MIN = 14.64 *.75 = 10.98
MAX = 14.64 *1.3 = 19.03

MIN = 1 *.62 *2= 1.24
MAX = 1 *.37 *2= .74

With that said, he could be maxing out the ability to learn and then the EEC is still trying to lean it out further with the LAMBSE.

Re: Lambse.. Explain
 

Mine, with Adaptive on and a stock MAF hits anywhere between 16 to 17:1 at idle. I've tried "correcting" this at least 20 times and the car starts idling rough and die. Same thing with part throttle crusing, I see anywhere from 15 to 17:1 Lambse.

Re: Lambse.. Explain
 

This is not strictly correct, it's possible to set the closed loop AF ratio from anywhere between 29.28:1 and virtually 10:1 if you know where to look in the code.

EDIT: typo fixed, changed 0:1 to 10:1
