Megasquirt/Haltech pics

[jdbubb at ix.netcom.com (Dan Bubb)]

The only thing you keep out of the original injection system if you're converting to MS is the fuel pump(s) and fuel lines. It also makes sense to keep the fuel filter and the fuel pump relay. MS will handle the fuel pump relay, but why change when the original works?
As for the rest of the intake system, I would also keep the auxillary idle air valve (or add it if you have a 16V) since the MS only controls a solenoid which is just off/on and isn't progressive and can't control an ISV.
Other than that, what throttling system you use is up to you. You'll need a fuel rail, FPR, injectors, intake air temp sensor, coolant temp sensor, TPS and various relays and wiring.
And to finish your installation off in style you need a nice cold air box for your ITB's and a nice K & N cone filter mounted to suck nice cold air.

  Alright, I am considering the MS system, but I have a few technical question
  and I think I sorted most out and I just wwanted to pass my ideas around to
  see if I am understanding this whole new setup I am thinking about doing on
  the car makes sense..

  1. using MS as I understand it will make possible the removale of the Fuel
  Distributor
  2. Using ITB's mounted on a Weber Intake Manifold (tracked a manufacturer
  that make them so that it can be iTB for an 8v (grin)) , I could match this
  setup easily with MS right ?
  3. now the ITb setup would make the oem Air intake manifold gone, and leave
  me with nothing but MS and ITB's (in my mind I could me missing something
  here please feel free to add in ideas/comments)

  ->I uploaded some more pictures to

  ->showing the fuel line installation and the CAI I fabricated.
  ->The fuel lines are clamped over the barbs on the existing
  ->fittings. The CIS delivery and return lines are plastic with a
  ->rubber covering. So, it's easy to cut them off and clamp a high
  ->pressure 8mm rubber hose over the barb.
  ->As for the CAI, despite its very forward location I've never had
  ->any problem with water ingestion even in a driving rain.

  ->  Dan,
  ->  Nice idea on the mounting bracket.  That's exactly where I
  ->mounted my J&S Safeguard unit, only I didn't make a bracket, I
  ->used industrial strength velcro.
  ->  Let everyone know when it's finished, I've got a lot of
  ->questions about installation I'd like to ask... like for one, how
  ->do you connect the fuel rail input and output lines to the
  ->existing fuel lines?
  ->  Thx!
