Just started/finished it yesterday. It's neat to watch the lights flash on the stimulator



The H-T go kart is getting closer and closer to boost. Now I just need someone to give me some injectors, a honda fuel rail + FPR, and a D series throttle body so I can make up the intake manifold/fuel system.

If you explain what the thing is or give me a link, I can send you some stock honda injectors

 

Hehe, it's a DIY fuel injection computer.

I got the kit from glen's garage ( http://www.glensgarage.com ). He includes all the parts + PCBs + CNC case. You solder it all together, and then it magically works.

Blurry picture (I'm too lazy to open the case and take a better one):



There are several programs for your laptop/etc to tune it. Here is a pic of megatune hooked up to the megasquirt:

Megasquirt

Many a formerly-carburated bigblock use this system. I wouldn't swap out a chippable ECU for it, though.

 

I just finished up the relay board for the megasquirt:

 

hey dustin, i can send you the injectors, fuel rail, and fpr. in return can you write a review of your build in some detail on decalfreehonda.org

msg me on aim, i'll give you the parts for free, just pay the shipping, and for kicks i'll bore the tb out a bit(intrested in see'ing what this boosted kart can do)

aim= menkio001 btw

 

Well in response to this thread I already have an FPR, fuel rail, and TB coming!

I'm still looking for injectors though.

The turbo has an internal wastegate that is supposed to be 8-10psi. 240cc injectors might be borderline for this boost level, but I'm not sure. I should work out the math again

 

I watched my buddy and a Toyota tech install a 3SGTE into a Celica and make a startup map with Megasquirt. Keep us updated as you progress. I was going to give you a fuel rail but I see you already have one. If you dont find injectors by the time I take my injectors out you can have them. Good luck

I have a VX that could donate some parts, I'm not shipping that crap though.

 

I have some 240's sitting around. IM me if you want them.

 

Might have some 320cc's out of an Impulse RS... they're being swapped for 450's. I've got a **** ton of 240cc, low or high Z your choice.

 

The issue now is that the megasquirt does not control spark.

There is a mod for it to control spark with a ford or whatever ignition system, but the kart only has 2 cylinders.

See, the engine already has kawasaki electronic ignition... but it is fixed and I cannot change the timing.

I might get lazy and just put 100+ octane in the kart. Maybe it won't ping

Does anyone know if an MSD BTM works on 2 cylinder engines with individual coils?

 

The MSD DIS-2 will control coilpacks.

You will have to set it for 720° firing and only use output #1, but it should work just as well as 4 coils on 4 cylinders (as on the 1.7)

I use the DIS on my Kia (which uses 2 coils for 4 cylinders, 360° firing), and highly recommend it.
