Hi , nice to join in the forum and I'm new to Hondata flaspro which it is current running on my k20 engine.

Just would like to understand more on Hondata which I am unclear in the closed loop setting.

Hope I can get guidance from all the pro here.

My setting current is using by default TPS WOT, but not Map Determination for WOT.

Can all the pro advice me that, (question refer to the picture numbering)

1. Is the closed loop target defines minium target lambda value?

2. Is the closed loop target lambda limit define maximum of the lambda value over ECT?

3. Is this define the target lambda target under low load? What is the low load? what is the low load refering to?

4. Is this define the target lambda target under high load? What is the high load? what is the low load refering to?

1 is not a limit, it is the target value
2 is the limit for that ECT value

Have you read the help file at: https://www.hondata.com/help/flashpro/c ... sub=lambda

Understood.

If say the target value was set at 14.30, does this mean that the ecu will control F.trim not lesser or highet than 14.30?

And if the ECT was set 14.6 at 80 degree C, does that mean that any temp on 80 or above, the ecu will control AFR not above or lower 14.6?

Thanks for the guidance

After reading your reply, I have created a table as the image attached.

Refer to my image, I would likw to know am I correct?

Hope to have guidance and thanks alot

Fuel trim is separate form the target. The fuel trim will be adjusted to meet the target.

Any temp higher than that will target the last value in the table.
