Megasquirt on Naturally Aspirated drag bike

[aaronxs400]

I asked Chris Horoho these questions on psychobike...he sent me here, so I figured id just post it up as a topic...


First let me tell you my setup. Stock 2006 motor in a chrome moly bar and slick chassis, sidewinder pipe, no air box, currently running a PC3USB. The bike runs a cooling system with no radiator, just a small tube.

I would like to switch to Megasquirt to simplify the entire system. There are to many boxes/wires and I feel that a simpler system would be the way to go.

So my question to you is...Could I run Megasuirt to control both my injectors and ignition system, using wasted spark, running just my factory crank sensor to, TPS, air temp sensor (athough im unsure why I need this), and the built in map sensor. I would also like to run a wide band O2 sensor to set up autotune.

Is there anything Im missing with this setup? Does it sound like it will work?


I would go the Plug N Play route, however this would really simply my wiring. The wiring harness is already at a bare minimum and its still to much.

Another reason I want to do this is to make the bike more consistent, as it is a bracket bike. The builder of my chassis, FBR Shop, has said that these bikes with a PC3 and factory ecu have 1/4 mile times that vary up to a tenth. They need several of the sensors disabled or a set value put into the ECU to stop them from trying to correct the fuel map. FBR shop also sells their own electronic package, but its $1500+. I think the megasquirt would be the way to go for both cost and simplicity.

Tell me your thoughts.

here is where I learned that I could drive 4 coils in a wasted spark setup using only the crank trigger wheel.

go down to 3. a.M-N crank wheel

and was going to use this:

to drive the 4 stick coils.
