Which EFI system to choose?

[William_Irani]

Dear All,

I'm a new member on the EFI101 forum and would really appreciate some advice from some of the more experienced members. I've been interested in EFI systems for a couple of years now but no first hand experience yet.

I'm looking to control a NA M113 5.4L Mercedes Benz V8 for a engine conversion project. My hp target is high 300s, stock is around 350hp so nothing crazy, plan to use stock injectors, coil packs and other ancillaries.

As a result i'm looking for and ecu that can handle 8 cylinder sequential injection and ignition, DBW throttle, wideband lambda control, CAN enabled.

Would also like to control a fuel pump using PMW, along with cooling fans and other basic functionalities. Not bothered about nitrous control, launch controls, traction control etc but I know these goody's usually come along with the 8 cyl sequential ECUs.

Anyway, so far i've mainly narrowed my options down to the MaxxECU RACE or the MS3 Pro EVO. They both seem like a pretty comprehensive system for my needs and price point.

If anyone on here has had experience with either of these systems or other systems they would suggest, the info would be much appreciated.

Thanks in advance.
