the initial generic figures are much different to your displayed ones.

Yeah it's a self learning table, also requires your primary fuel table to be decent (with in reason)

Yep, sounds good. I suspected that to be the case. I'll be able to drive the car late this week, so looking forward to loading up some fresh data and testing it

Here's a funny joke, so got my laptop back from Lenovo after 3x weeks, and literally after one day of use, it's dead again 🥲

Great service!

Is the laptop the problem, or something youre plugging into it killing it?

Not sure?

The same Lenovo USB-C dock is shared with a Thinkbook and T490S as well. It's in the study so either my wife plugs her laptop in, or I plug my work or personal one (Yoga 7i).

Can't be the dock, as the other laptops are still fine.

Got my laptop back after 3x fking weeks at Lenovo... pricks.

Anyhow, here are some screenshots of my tune and how I've calibrated my shit box.

This is the best thing to come out on the Haltech since sliced bread:

 

If you make all this say 15 instead of 12 or whatever so there's not a big timing jump between 950 to 1000 the idle won't "brap" as much. I did this because I am a poser

 

Decel, I find adding in heaps of fuel on recovery stops the idle being aids

 

Also defining fuel density vs. ethanol percentage vs. fuel temperature immensely improved the car's driveability 

 

 

Ok, so i've uploaded the changes i made during the week to the car (MAP prediction, LTFT, a few other things).  
First thing was drivability (on-off throttle in light traffic, roundabouts etc) was very improved.

i am experimenting with turning off/on the decel fuel cut. See how that goes, it drives awesome on/off throttle at cruise speeds as its not jerky when constantly fueling.

The most annoying hurdle i have atm is the idle staying about 300rpm high when i roll to a stop, hanging high for ages, or until i touch the throttle. Not sure what this could be, something to do with closed loop interfering due to a bad setting?

And some jerkiness is still there as the car slows to a slow roll... smoother idle has helped i think

Try lower the base duty cycle on for your idle table.

 

Also check if your TPS is calibrated properly (don't follow the OEM guide, just go into calibrate TPS in the Haltech settings menu and follow the 2x step procedure) if not the ECU will not enter idle state properly

Awesome, i'll try that. Legend!

Another way to see what the idle is doing, is to graph it in real time.

On the time graph select the idle base duty and the actual duty and the error rate.

That way you can set the base duty a bit higher than what the actual duty cycle applied to the idle control valve.

On the slow Nissan IACV, I like to set the base a tiny bit higher than the actual duty cycle during correct idle and target rpm, allowing the closed loop idle strategy to reduce the idle duty as required to meet the target

Sounds like good advice to me. I'll work out how to do that, and have a crack. I think the remote mounted iacv might theoretically be laggy also compared to stock mounting position.
