Ok, I have a ms1 v2.2. I have been running 4-550cc (stock s5 tII) injectors, However, now that I'm at max (and then some) of the duty cycle, I need to upgrade.

I came across a new set of 4 1600cc injectors for very cheep that a buddy had. Im on e-85 and single walboro 255. The ohm reading of the 1600cc are around 5. quite high for low z. according to the megamanual, no resistors are needed. It does run, but not to my supprise, i cant lean it down enough at idle. so, i guess the real question is, can I keep the 1600 cc injectors as my secondaries and use the 550's for the primaries, even though they have a dif resistance?

 

Should I run a resistor pack like everyone else that ive seen?

 

Search these topics by my username. I outline part numbers and everything.

 

Thanks jobro, i actually printed that whole thread off last week, but really was kinda nervous about this whole thing. thanks for the help
