PKIT – MegaSquirt-I PCBv3.0 Partial Kit

When should I use a V2.2 board, and when is it worth stepping up to a V3.0 or V3.57?

• The V3.0 and V3.57 are significantly more flexible. For a new build, a V2.2 could be cost effective under the following conditions:
  • You will be running high impedance injectors.
  • You will be using fuel control only, or one of the following ignition systems:
    • Ford TFI
    • Ford EDIS
    • GM HEI
    • VW Hall effect distributor and “139” ignition module
  • You do not need any other outputs beyond fuel and ignition control.
  • You do not intend to upgrade to MS2 or MS3 in the future.
• If your plans include any features beyond this, starting with a V3.0 or V3.57 is likely to be a better option.

What firmware is on the processor?

• This processor ships with B&G V3.0 code. You can install other code variants when you assemble the ECU.
