I've been slowly getting my engine mapped. Today I played around with the closed loop settings. I followed some of the suggestions from the other post. The settings work great at idle. However, any time I give it throttle, the LAMB % goes to 0.0 no matter what. Attached is a graph of Lamb,Lamb %, and RPM. My lambda table is currently set to 13.0 all throughout. Why would the closed loop basically turn off when I give it throttle? And the moment I drop back to idle, the closed loop kicks back in and holds to 13.0, until I increase the throttle again.
My setting is set to turn off closed loop above 14000, and throttle of 101%. So I don't think that is the problem.
Below is a shot of the graph.

Re: Help with Closed Loop
Those were very slow throttle engagements. 1% throttle over 8 seconds. Held at 2% for 15 seconds, and the lamb % stayed at 0 for the entire time.
Re: Help with Closed Loop
What is your over-run throttle position set to?
Is it a black "0.0" as in turned off or blue "0.0" as in not making any adjustments?

Re: Help with Closed Loop
Over run throttle position is 3%.
It had to have been black, it was not close to the target value at the time. Lambda was near 10, the target was 13. And it was just adjusting prior to the throttle application.

Re: Help with Closed Loop
Maybe there is an issue with e-race, i had it once:
If the max is 0, the data log is filtered so that everything above 0 is shown as 0.
Change the E-race graph limits to +20/-20% in the Lambda correction graph.
what are the correction limits and other parameters, can you post a screenshot of the parameters?

Re: Help with Closed Loop
Its not erace, the DAT file shows 0s, and I saw it on the real time chart.
cant post a shot right now, but the correction limits on lambda are +/- 15%.

Here is a copy of my lambda parameters.

Re: Help with Closed Loop
I have the same sensor (innovate LM1/LC1) and its been working fine for over two years now. Every single parameter you have looks 99% same as mine, Except i have MAP as load and "suspend closed loop >100mV" is not checked..

1% or 2% is less than 3% hence no correctionsmatthud322 wrote:Over run throttle position is 3%.
