HA Motorsports has consistently delivered a positive experience. Their customer service, and overall professionalism have been excellent across the board. ( seriously! )
Ktuner, on the other hand, has room for improvement particularly in both hardware reliability and software refinement.
Over the years, I've used multiple Ktuner setups, including both the in-ECU units and the 1.2 flash devices. My experience with the in-ECU hardware has revealed a recurring issue with intermittent "reboots" while driving. These episodes cause a brief but complete loss of engine power, accompanied by a Check Engine Light and battery warning on the dash. It happens so quickly that it’s easy to mistaken for a hiccup in drivability, but it’s consistent across all three Honda/Acura vehicles I currently run with Ktuner in-ECU interfaces each exhibiting the issue with varying frequency. I ignored it for years till one day I was mid corner on my last hot lap and it rebooted during a slide… I was so close to going off track.
It’s like rolling the dice.
On the software side, Ktuner’s platform has seen minimal evolution over the past seven years. It remains buggy, prone to crashes, and slow to load even on high-performance computers. The datalogging interface is clunky and unreliable, and ECU connectivity issues are frequent. Compared to alternatives like Megasquirt and Hondata, Ktuner’s software feels outdated and in need of fundamental improvements. ( it looks good though )
Bottom line: If there were another viable option for my platform, I’d likely switch. However, given Ktuner’s unique compatibility and ease of use, I continue to purchase and use their products. Despite the frustrations, they do ultimately work and that’s what keeps me coming back. For now.
Pls fix the rebooting thing. It's a safety issue.
Great customer service
Works perfect on my accord with the JDM k24a
