  1. Knock control error/ low octane

    Problems & Solutions RSX
    My car is stock, 200k+ miles if that matters. only pump 91 but my ecu reads the fuel as lower than 91. I don’t know if its bad gas or winter blend gas but it’s knocking. Sometimes it’ll read correctly and won’t knock. Anyone dealt with this?
  2. Changing 94 N/A octane map to 91. What to do?

    ECU Tuning RSX
    Hi guys, haven't touched my kpro in YEARS. I've driven on 94 oct for last 7 years but now gas is getting to be a little too expensive in my area. Im wanting to back down to 91, what should I change in my map? my mods are I/H/E/intake manifold. Im thinking stepping down ignition slightly across...
  3. Help, base model RSX calls for premium octane fuel

    Problems & Solutions RSX
    As stated, my 06 "base" RSX calls for premium fuel but as far as I can tell the only mods on it are a type S exhaust, cold air intake and type S badge(adds 40 horsepower). As you have probably guessed I'm not the original owner. Also hearing a few noises I don't like for instance when I'm...
  4. Octane Q but not what you think

    General Discussion EP3
    So ik there was a big fight over 91 octane vs 87 but this is a little different, Could switching between 87 and 89 octane gas possibly cause a check engine light? It seems like when i go a few weeks on just 87 (:weeeeeeeeee: gas prices) it goes away...any correlation? :wait:

  9. Blending E98 with 91 octane

    All Motor RSX
    I've been researching blending e85 with 91 octane. I was thinking about running a 40.0% ethanol mix. Mix 4 gallons e85 and 6 gallons 91 octane = 95.4 octane average. My question is would I have to upgrade my fuel pump and lines for this 27% ethanol mix. Current setup is high compression...

  12. K-Pro stock tuned 91 octane calibration

    General RSX Discussion
    So I know this is an ECU question but I havent been able to get any answers over there yet. I bought a k-proed PNF ECU to put in my 03 base and on the Hondata forums he said I will probably lose power because I wont have AIB control. Meaning? Im assuming its related to the intake runner control...

  14. 89 Mid-Grade Octane

    Problems & Solutions RSX
    So today I accidently put about 3/4 tank full of 89 Mid-Grade gas. Should I be worrying? It has about 45% gas left Should I put Premium 91, gas on it right away, or just wait for it to get almost empty then put premium gas? I'm just glad I didnt put regular gas though P.S. Glad to be part...
  15. 93 Octane on a stock RSX... good idea?

    General RSX Discussion
    Dear guys, I was just wondering if this would cause damage and if it's any use doing it, performance-wise and mpg-wise on my RSX-S? I just have a place by my house that's only a nickle more for 93 octane, considering that's the case, if it was any benefit at all, I could use it every time I...

  18. Which octane?

    All Motor EP3
    I have searched and searched for a discussion on this but found nothing. I am either terrible at searching or, well, this hasn't been discussed. For a stock si (02-05) does the octane of the gas really matter? My first fill up was with 87. Reading through the owners manual I read something that...
  19. Flanz: Full-Race GT35R, stock-sleeve K20Z1, 93 octane = 570whp @ 23psi

    Turbo RSX
    Hello all, Today, I had the pleasure of tuning Dave (Flanz)'s car again today. As I'm sure most of you know, Dave had some troubles with the last setup that was on his car, and was looking to find something that controlled boost pressure more consistently and predictably (a.k.a. properly), so...
  20. Jet Pep 92 octane fuel cheap, but worth it?

    General RSX Discussion
    For the past year, I've always used Chevron "premium" 93 octane fuel. Now it's getting so high I can't afford it. I'm paying $3 bucks now, and everytime I go lately, it's up another few cents. Analysts say regular will be up to $3 by the summer, which will make premium $3.50, and that will mean...
