Setting correct closed loop conditions

[Boostedvti]

Hi there,

I have my PLX wideband installed and connected to the ECU via the ELD input.

Now this maybe a silly question but I want this to be right first time.

I want the ECU to read closed loop up column 6 in the fuel map so under parameters, then in the closed loop tab, do I have to put a minus figure? eg -7.2" or do I just put 7.2" in the box?

The same goes for Target Lambda in the Settings menu. Do I have to put minus values in or doesn't it matter?

Many thanks in advance

This all depends on what you have the units set to in settings.

Column 1 reads -25.8" and column 6 reads -7.6". Therfore to set the maximum MAP for closed loop, I put in -7.6 in the conditions box. Am I correct in this?

Also in the Target Lambda in the Settings menu, for Low Load, I want -7.6" (Column 6 and below 14.7:1). Am I correct in this? I have Vacuum Unit Base set to Atmospheric and Pressure Unit Base set to Atmospheric

What are the units in the closed loop tab?

What are the units in the closed loop tab?

Inches. I forgot to put that in my previous post. I meant -7.2"

You do not need to put the negative.

Ok, thank you very much for that. Overall, I'm pretty impressed with the S300 Smanager software. It's very similar to the CROME Pro software which I have previously tuned with.
