    SHO/FZR big boost wheel/ rrfpr/ no ecu?

    Has anybody tried using a big boost wheel with the RRFPR and no aftermarket ecu?

    What is the stock rev limiter?

    I am just thinkin out loud-- maybe we can use the same approach as the 80+ mph rxps on stock ecus.

    Is RUDE coming out with any Yami parts?

    Rev limiter sucks IMO. Need to get past that. Priority 1.

    Oh, and boost too.

    8500 safely I would say.

    so the factory ecu has a boost limiter and a rev limiter. Jim has found the way around the boost limiter. Is there any way around the rev limiter besides going to the r&d re-programmed ecu.

    I was thinking:
    et wheel
    frozen boost or jd1 ic
    larger injectors w/ rrfpr

    why not reflash? You can do the reflash and a lower boost wheel and no rrfpr or injectors and still be faster.

    true-- I always lived by more boost = more power. When I was building high hp turbo hondas we would just crank the boost up and leave the rpms alone. What is the max on the r2 upgrade-- when do you think you will need to go to injectors and/or rrfpr for additional fueling? Is the powershot a must with the r2? thanks!

    the reflash wont support injectors you must use the rrfpr but it is only necessary over 13psi. A r2 flash is limited to 8750 with soft cuts randomizing at 8500. I see 8600 consistently. From my experience trying many many different setups the most easy,safe and fast setup we have done is the r2 flash, c3 wheel and powershot. No rrfpr needed and the powershot was preprogrammed almost dead-on. 82mph+ all day!

    C3

    When you say C3 you mean the one that is 2 pounds more than stock not c3-11 right. That sounds nice if it is the C3 not pushing the motor to bad and going 82 all day
