Hello,
I'm in the process of gathering parts for the efi retrofit on my chevy.
I calculated that the engine would require 42 lbs/h injectors and the supplier of the manifold suggested bosch injectors.
I see there are several types running from low impedance to high impedance. As far as I understood, ms does not support 8 low impedance injectors... so i'm confined to the high impedance types. Anyone have a correct partnumber for those and what are the disadvantages from low to high impedance ?

Re: injectors: newbie q
My V12 Jag is running on 12 low impedance injectors, 6 per injector circuit. In fact, I have come accross a serious pro ECU that can NOT handle low impedance injectors (in an optimal fashion that is).Yves wrote:As far as I understood, ms does not support 8 low impedance injectors... so i'm confined to the high impedance types.
Still, if I could choose I would go for high impedance- just to eliminate possible flyback issues.
Best regards

What size motor are you running? Fairly stock V8 42lbs would be in the range of 4 injectors and TBI. That 40-50 range seems to be where many of the injectors switch to low z's. Below that the common ones tend to be High z's. But Im fairly new to this so I could be wrong.
