KPower Industries K24 swap

[captain awesome]

I'm definitely getting a tune, just not sure where yet. Tuned By Shawn and Humble Performance are on my short list with Humble being a 2 hour drive away. l'm mainly looking for someone that's known for both Haltech AND k24/20 tuning experience. Since most K tuning is Hondata I want someone familiar with the platform that can extract power and drivability. If anyone has other suggestions that would be awesome.


As for switching to NSP I haven't yet but am ready to do so. ML has switched and may be able to chime in with more info about making the leap.

I uploaded the tune to the ECU first with ESP and then upgraded the software/firmware. Then just plug it back it in and the NSP works great. Its a lot more intuitive and the dark mode is 100% worth it no matter what lol.

I don't have wifi in my garage. Can I update the firmware by taking the ECU into my house and updating the firmware, and then can I hook it back up and apply the settings?

You download the software on the laptop and then plug the laptop into the ECU while the battery is connected. The ECU needs power from the car in order to be able to hook the laptop up to it.

That's what it looked like on Haltech's videos, but it also looked like they downloaded NSP, and then they connected the laptop to the ECU, and then they connected to the internet through NSP to update the firmware for the ECU. I don't think the firmware is downloaded with the NSP software and stored on the computer in such a way that it can update the firmware without the internet, but I could be wrong; that is just what it looked like from the video.

You download the latest nsp software to the laptop, and when you connect the ECU it updates the ECU to the latest software on the laptop.

Did you mean it updates the ECU to the latest firmware that is stored on the laptop without the need for the internet? Sorry, just clarifying.

Yeah, with internet you download the nsp onto your laptop, then take laptop to the garage and plug in the ECU. Pretty sure it walks you though the process. When the nsp software first became available I messed with it but never actually switched after getting the car running on ESP.

While working on my idle tuning today I realized just how jacked up this base map actually is. Target AFR along with a a bunch of other items are utilizing CABLE throttle position sensor for the data. So essentially the whole damn AFR map and a few others were completely useless, car runs much better after switching over to DBW TPS in each menu. I truthfully hadn’t done any data logging prior to today. The car ran great and felt slightly faster than with the fa20. But when I noticed the AFR staying super rich at the top of 5th gear I decided to investigate. Previously I had just glanced over during a couple pulls and saw that AFR looked good but I wasn’t looking over at 8k.

I updated to NSP and it's way nicer. However I looked in both and don't see where you can change the CABLE to TPS?


Also fixed my jerkyness at low RPM with light throttle input. The provided map runs 1% threshold arming of TPS. I went the opposite direction bumping it to 3% making it worse originally due to misunderstanding the function. Someone suggested I adjust it lower so I made it .5% and now it's working great. At least from the test miles I just ran so far.

When viewing a table, AFR map for instance, click the table axis setup next to the main setup tab. Once in there you can change the axis from cable to Dbw.

Shouldn’t the TPS to AFR map be the same regardless? The difference with DBW is a person could modify the throttle position to be different than the accelerator position in a way where they are not 1:1. Like a cable system would be linked to the accelerator in a 1:1 ratio, but airflow through the throttle body wouldn’t be 1:1 because of the nature of airflow being greater in the middle and less towards the end of throttle opening, but DBW can be set up to deliver a linear feeling to airflow through the throttle body, and that requires a more exponential input curve for throttle body opening relative to the linear accelerator input. Regardless, AFR at 80% throttle should always be the same, right?

Were you altering the map or just looking at an identical map with a different value? Sorry, I haven’t dug into the software yet, or I would look myself. Still fabricating.

Has anyone used the traction control system? Does this have stability control or just traction control?

Before I plugged in the Trac Box it seemed to be as invasive as it was stock in all of the various settings. Didn’t drive that many miles before the box though and I have it set to pedal dance mode at all times.
