Would there be a valid argument for changing this setting if running on 91 vs 93 octane gas?

Adjusting a VMAP. How do you do it and should I even bother? - Adam_P_Green 2015-06-02 12:46:12 (531 views)

  - Yes (inside) - UrS4boy 2015-05-22 16:31:29 (312 views)
  - Read my mind. See my post below "Nobody had mentioned Octane" (and they hadn't until now) - UrS4boy 2015-05-22 16:30:47 (256 views)
    - I dont see any point in adjusting because of altitude. Our cars already have an altitude correction - dustovich 2015-05-22 16:44:47 (280 views)
      - I believe that all the performance boost chips being sold eliminate the barometric pressure - scarman 2015-05-22 18:19:18 (253 views)
        
        Interesting point. Not that I dont believe you, but do you have any substantiated proof? - dustovich 2015-05-22 18:30:38 (216 views)
      - Where did I say altitude? I said OCTANE. In any case, you might want to read this (inside) - UrS4boy 2015-05-22 17:19:12 (253 views)
        
        Octane was already covered oviously, the OP was talking about altitude if you didnt get that. - dustovich 2015-05-22 18:09:47 (237 views)
- I ran my Steve Eiche MTM I+ @ 2.8 bar for years and years no problems. - TabulaRasa 2015-05-22 13:53:58 (312 views)
  - I agree, it seems like the altitude argument is splitting hairs for the most part. - Adam_P_Green 2015-05-22 15:16:53 (275 views)
    - 92 octane is the highest rating that I can usually get. - TabulaRasa 2015-05-22 17:24:09 (227 views)
- I would hope that better answers were available from Steve Eiche about the chips he produced. - scarman 2015-05-22 13:17:52 (339 views)
  - Thank you, Tom. This is probably the clearest description I have received yet. - Adam_P_Green 2015-05-22 15:10:24 (252 views)
  - I asked a similar question about running a set 3.3 bar at sea level currently on a stg 1+ setup - fattycharged 2015-05-22 14:40:45 (287 views)
    - There would be limitations at some point, e.g. injector flow/duty cycle.Nobody has mentioned Octane - UrS4boy 2015-05-22 16:29:48 (254 views)
      - gotcha, we run 93oct here in Houston and its usually pretty good petrol - fattycharged 2015-05-22 16:58:31 (237 views)
- Yes you should bother. You're leaving performance on the table. A jumper is basically a little - UrS4boy 2015-05-22 12:07:40 (363 views)
  - Great resources, Dave. Thanks for sharing! I haven't seen that video before and find it helpful. - Adam_P_Green 2015-05-22 15:19:16 (238 views)
- just move jumper 4 to 3. good to go. - running_cold924 2015-05-22 12:06:43 (273 views)
