  1. 1.5T Weird ECU version? Can't buy OTS tunes...

    Greeting my fellow CivicX-ers. I first tuned my 2019 Honda Civic Touring Sedan (CVT) in late January with the Ktuner basemap, and when I decided I wanted more I switched to the TSP Stage 1 tune, but my ECU version was not listed on their website at all, so I contacted support. I noted this in...
  2. Upgrade Time - Need to make a Decision

    So I only have one year left on my 2020 Civic Si Warranty. It has been good to me besides an AC Compressor going out which was obviously covered under the recall. Im about to hit 40,000 miles on the ODO. So I think its time to say "to hell with the warranty" and get some more power and sound...
  3. Phearable 1.5R Question

    Is the 1.5R tune custom tailored to each car? While ordering the tune, it asks for modifications and fuel octane, is that just to make sure your car can handle the tune or is it for a custom tune tailored to your car specifically? If any questions about modifications on my FK7, I'll put it down...

  9. Needing a new tune for cold air intake?

    I recently put a K&N Performance 63 Series Air Intake System onto my civic, after driving around with it I feel like I've actually lost power which was weird. After looking into it apparently you need to let the ECU adjust to the increase in air but I've also seen people seen people say you...

  20. RPM hang solution?

    With the CVT, I notice that on heavy acceleration the trans would rather hang in high RPM’s than shift to a higher gear. Paddle shifters kind of alleviate this, but is there any solution to this (a tune etc)? Or is this just a normal CVT quirk.
