550/850 = 64.7%, how did you get 68% for the primary precentage?

Use a base FP of 38-40psi at 0 boost.

Primary inj lag is set by adjusting it to get ball park smooth idle as 850s will somtimes run too rich to allows using the fuel correction map. Search on 850 and read many threads about 850 primaries.

Secondary inj lag of .10 for #1 and .20 for #2.

All of this has been posted many times.

thank you for your reply , the 68% was done by the last onwer. so i will correct that , to

65.0? and the secondary inj lag what do u mean by #1 and #2 ?

thread.

Did you switch out your secondary injectors? the original owner was running 4 850's not 1300's.

yes i did the RC1300cc

The rear rotor(2) tends to run a little leaner than the front rotor(1) thus a little more lag makes it run a little richer.

hellokitty812

ok so that means .1 in the front and .2 in the back right ? Also i set the PR 850 to 65 % will

that work ?

again thank you very much

hellokitty812

no one is 100 % sure about that ? what are your setting ? no body use 850/1300 ?
