  1. 0 boost at light throttle, slow turbo spool, no boost leaks

    After 4 months of diagnostics and a lot of money spent, I still cannot find what's wrong with my car. It seems like a boost leak, but there isn't one. It started after I swapped my intercooler and cracked my turbo from an initial boost leak. One of my clamps had sheered and loosened slightly...
  2. Does knock control or running lean reduce turbo spool?

    I have 2 threads open with barely any replies so I'll try to take this from another angle and only ask specific questions. I don't have a boost leak but my knock control is super high and I'm running lean, with barely any boost. Accelerating normally, I can't make it past 0 PSI but if I push...
  3. Not building boost unless I really push it

    So this issue started a couple weeks ago except it was accompanied by a loud sound in my engine. Found out I had shaft play and a crack in my turbo. Just got it replaced today and I still have no boost. When regularly driving I only hit 0 or 1 psi and if I really push it, it will lag up to maybe...
  4. Can't see fuel value table on flashpro

    I'm attempting to setup auto tune on my flashpro but while following along with tutorials on YouTube I can't see "Fuel Value + RPM" table like what everyone else seems to have. Am I missing some kind of setting or is this not included on SI trim?
  5. Higher Idle After Tune

    I ran into a new problem a couple days ago, I'll keep it short and simple. I re tuned my car after discovering there was an added throttle sensitivity setting. I kept the same throttle response, faster turbo spool, deleted rev hang. But I also changed my intake configuration to the Injen SRI...
  6. Loss of power after idling for an hour

    2020 SI, mishimoto intake and hondata tune for about a year, no issues at all. An hour ago I sat in a parking lot waiting for someone, in the sun(88°F), for about 40 minutes. Half way through I let my car run for about 10 minutes in case the battery was low. The whole time I had my fan...
  7. Is my shift time (with tune) normal?

    Sorry for the poor quality, took me like 4 attempts to get my super HQ android video to a viable file size. I have Hondata tune with rev hang disabled, or so I think. I don't remember if the rev hang was always this bad but I feel like maybe my rev hang disable didn't work. Is this a normal...
  8. Remote Heating For SI?

    Note sure if anyone's asked this before, I did a bit of searching and couldn't find any discussion on it. I know you can get a remote start package for a manual but why didn't Honda incorporate the ability to remote heat via the heated seats and glass defrosters? It would be customizable, for...
  9. Rev hang disable only works intermittently

    So I have a new SI that I tuned and disabled rev hang, it worked really well at first. And then I experimented with the +9psi, then reverted back to +6psi(stock tune). After that my rev hang disable will work temporarily and at random times. Not sure if maybe it's a bad tune(I did retune with no...
  10. Running lights not working after installing light upgrades

    So I installed front side marker LED panels which are popular on Amazon, tested them and they worked, I didn't plug in the blinker option because I couldn't figure it out. Then I installed rear reflector LED upgrade and began wiring them into the pigtails with trial and error, while following...
  11. Something wrong with my boost scramble

    I used boost scramble for the first time today. I've had it for a couple weeks and only accidentally activated it once. The thing is that when I activate it, the RPMs jump to 5000 which I'm sure is to let you know it's on. But when I drive with it the RPMs bounce all over the place and trigger...
  12. Will altering MAF sensor cause emissions code?

    So this is my first post, just got a brand new 2020 SI, I had a 2018 EX-T prior with homdata tuner and mishimoto short ram intake. Well the intake didn't quite fit the SI because the MAF sensor was too big for the housing of the intake. Well, I decided to shave down some excess plastic on the...
