  1. P0134 but A/F is changing in KManager

    Problems & Solutions RSX
    So I installed a KPro V4 in my RSX a few days ago and the code for P0134 popped up in my KManager program only after the ECU was installed. While performing a datalog though I noticed that the car was not in limp mode as I've noticed others say happens and I'm able to see the AFR approach 14.7...
  2. Questions about A/F Ratio not reading on KPRO

    ECU Tuning RSX
    Does anyone know why my A/F Ratio is not reading on KPRO ? I have a check engine light code for "P1166". I know it's a code for the primary but wouldn't it still read A/F Ratio ? I was assuming this would apply for the Secondary o2. Any help would be appreciated.
  3. A/f ratio

    ECU Tuning RSX
    Hey guys, so I recently got Kpro and I'm trying to run my AF to a pretty linear curve at 13:2 - 13:5. I have it relatively close, just a few more tweaks. But right around 4300 (vtec) it spikes up to about a 14:1. I've added fuel to this area but it still spikes. So my question is, is it supposed...

  10. Effect of altered A/F ratio and altered ignition timing

    ECU Tuning RSX
    I just saw this YouTube video by haltech showing that af ratio doesn't do much to the power when changed but even small adjustments to the ignition timing make huge differences. Does anyone have anything to elaborate on this with? I'm really curious if it's the same way for the kpro or for the...
