Simple ECU for Bike Engine Car application

Morning,

I am building a track only car using a Suzuki Hayabusa Gen 1 engine and am struggling to decide on an ECU to buy. The set up on the Gen 1 engine is fairly simple with the usual basic sensors for air temp, intake temp and pressure, coolant temp, oil temp and pressure etc. Some of the ECUs I have been looking at seem way more complicated than I need for this application and are quite expensive.

A couple of the budget friendly options I looked are the Fueltech FT450 (advantage of having the display and ECU in one unit.) Megasquirt but that seems to be less used these days and Link which I do not know much about yet.

If anyone out there have been through this and have some suggestions I would be appreciative of that information.

Thanks

Brian

Is there a reason you don't use the stock ECU / wiring harness (stripped of un-needed parts), and Woolich Software to tune it?

This is the used successfully by many SCCA P1 / P2 / F1000 cars. George Dean Racing engines can strip down your harness and probably even tune the engine if you wanted to send it to him in Seattle.

David,

Using the OEM ECU was my first plan but got sucked in to all the new shiny stuff I probably don't need :-) I build harnesses and plan to wire this car from scratch so no worries there. You may have just convinced me to go with plan A as I have a couple of these ECUs on the shelf gathering dust.

Thanks

The only reason to go to a stand-alone ECU is if you need features you can't support otherwise. I started with stock ECU's on our Suzuki GSXR-1000 engine, but am currently running it with a MoTeC M130, with knock control, sequential gear shift rev-matching, and sometimes traction control.

But as you've noticed, this is not the budget solution.

I agree, if you're not adding sensors for failsafes and only want the engine to run well, you might as well tune the stock ECU.

Personally I'd go standalone to add the failsafes, along with fuel pressure and oil temp/pressure sensors at a minimum, but that's just me.
