After more power 4.2 carby dual fuel

[Robo]

Yep above 3k rpm any way.
Not very cost effective unfortunately motor worth 4x more than I paid for Mav in the first place.
and this is still considered fairly stock.
wonder what the ancillaries would do to the 4.2 if transfered over ! .
running 700cc injectors on rb26 now.
"don't get me going".
what iifff !.

dunno about the computer but trying to tune both fuels is very difficult

that's the idea of dual maps.
about the only thing to compensate for.
plug gap and timing.
but this is normal stuff and acceptable.
