  2. moody engine or clutch slipping ?

    Can you run a datalog? If so, just do the math and see if wheel speed = calculated speed.
  3. Civic si strange noise at idle

    Similar to this noise? Dealer said it was high ethanol % in HPFP on mine.
  4. Rotten Egg Smell?

    When my car was new, I had the sulfur smell almost every trip after backing into the driveway. Now days, at 15k miles, i only get the smell if I am driving hard prior to backing in. Don't worry about it, it will go away. And if it doesn't or is very severe, warranty!
  5. 10th Gen Si Owner Abuses and Blows Motor

    He got permabanned after his last temp ban. He was trying his best to be a good boy! LOL
  6. FS 2018 Civic Type-R Southeast AL

    Looks like carvana is offering $33.3k. If you really want to get rid of it, that's an option.
  7. Strange startup sound?

    I think it might be a gray area since a lease is like a rental and financing - the bank owns the car. Here is something another forum member found: https://www.civicx.com/threads/anyone-know-what-this-is.39456/#post-653369 Bnois; I'm really not sure they would give you any paperwork. I guess...
  8. Strange startup sound?

    Are you leasing it? Is this your first auto loan/bad/no credit? Sounds like a recovery module (aka GPS tracking). They are not supposed to alert at random times. I bet someone wired it in wrong, and is sensing a voltage dip at startup. Take a look under the steering wheel. You could try...
  9. tell me what to mod, ill do it.

    I spy Digikey box?
  10. tell me what to mod, ill do it.

    Please do a side/hood exit exhaust.
  11. Big mistake ordering my intercooler?

    Wow suggesting bankruptcy for less than 3x yearly income worth of debt. Someone has been watching to much of "The Office". "I DECLARE....BANKRUPTCY!":slap:
  12. Help with clearing codes

    Without over explaining, the code reading/clearing feature is a simpler operation than actually tuning the ecu. The ktuner is simply acting as a obd2 interface. It is sending a read codes command, then a clear all codes command.
  13. Help with clearing codes

    Pretty sure you will need to reflash with the updated error code block in place. In the description of otf tuning, it states that after tuning you need to reflash for it to save. I imagine this is the same sort of deal.
  14. My Si is back and is stronger and hotter!

    Welcome back @BoostedSiCoupe. I'm going to be doing that same tire package here soon. What size did you end up going with? I was going to try and get a 245 wide on the stock wheels/ride height. Also, I want to do the full map race DP/FP/exhaust. Might as well take advantage of no emissions...
  15. Knock Count?

    Has anyone ever explained WHERE the k.con number comes from? As a technical person, I find knowing where data is coming from helps me understand the data better.
  16. Si lease?

    I leased my Si, traded in a car that was on its last legs (Pontiac G6). I got $2000 for my trade, put trade +~$400 down. The dealership could not get the Honda deal to work. It is very possible that I was getting the run around though. Payments came out to around $325. If I were you, I would...
  17. 1st and 2nd gear question

    Na not every time. Maybe 6 or 7 out of 10 starts. Keep in mind this is at full operating temp & mainly just for fun. If my wife is in the car, I will usually shift around 3k.
  18. 1st and 2nd gear question

    Same car, same manual experience, same issue. ;) I'm at 6, almost 7k miles. What I have been doing is slipping the clutch a little when going into 2nd. This seems to help pull the revs down a little faster to match. Also, I rev 1st out to 4500-5000 rpm. I'm honestly not sure if I'm helping or...
  19. KTuner V1.2 data logging showing boost way over target?

    I took a look through the log. I'm no expert tuner, but that looks like a glitch in the reported pressure, or the log. Map did not jump at that time and it only happened for a brief moment. Definitely something to keep an eye on to see if it is repeatable.
  20. KTuner V1.2 data logging showing boost way over target?

    Are you sure you are reading in PSI and not mBar? If we take the 24.05 as mBar, 2405 mBar - local Baro pressure of 1024 mBar = 1381 mBar. Converted to PSI that's 20.0 PSI. Still seems like a little over boost for a 17.0 PSI map. Did it seem feasible for the boost pressure to change in the time...
