Been looking a Micra Dynamics boost retard unit.


best i'll be able to get,




RPM = B4 ign -----New ign = boost

1000 = +12' ----- +8' = -10psi vacum
2000 = +18' ----- +18' = 5psi boost
2500 = ---0' ----- +11' = 20psi
3000 =- +2' ----- +13' = 19psi
4000 = -+6' ----- +15' = 18psi
4500 = -+8' ----- +10' = 18psi
5000 = -+9' ------- +9' = 18psi
5500 = +12' ----- +12' = 17psi
6000 = +14' ----- +14' = 17psi
7000 = +15' ----- +17' = 17psi

This is using a different dissy i have (tt) with 3.5' retard every 1000rpm,
and re advanced at 5000 rpm (this is done in %, so i sort of estimated it,
as dont know what its a percentage of, if its 3.5' per rpm, of amount its retarded @ last retard = 5000rpm). so i averaged it out.


As you can see its not ideal, but alot better than before between
