Theres been a lot of talk, but not much action on this topic, so to stop Fridgefreezers continuous prodding here goes!
Fridge & other illustrious MS convertees
I've followed your Megasquirt V8 chronicles with both interest & humility.
you're about to hear a lot more from me in the coming weeks.....
Backgound:
Here in Namiba, Africa a much worked on 88" Series 2 A with...
A 2.25 5 main bearing rebuilt and rebored to a 0.4" so now a 2.32 give or take
K&N filter
ported head and intake manifold
branched exhaust manifold
big bore exhaust with single free flow box
2.5 Camshaft
Problem:
V8 like fuel consumption without the go! Weber 34ch not really giving greatest performance or economy...
Solution :
Megasquirt the old dear...unfortunately not an off the shelf solution in the local shops.
I've gone crosseyed sitting up on ebay and right now from around the world a vast array of Efi parts are winging their way to Africa... my local post office are in for a surprise! My Visa card is tired...
The following bits have arrived:
GM (Vauxhall) Single Point Throttle Body Injector (Includes injector, fuel pressure regulator, Throttle Butterfly, Thottle position sensor, Stepper Idler Valve and various MAP take off points.
Plastic intake hood for the TBI above ( this fits properly and helps eliminate leaks)
Ford EDIS ignition module, trigger wheel, vr sensor, coilpack & leads (this seems the most reputable ignition system available)
A crash sensor (thrown in free with the EDIS, cuts power to FI high pressure pump in the event of a shunt)
I have the following on its way:
Megasquirt 2 V3 (MS 2 necessary for Idler Stepper motor)
MS Relayboard ( To tidy up the engine bay wiring, and protedt MS from me! Good idea on a car thatdid not have EFI previously)
Stimulator to test the MS (I'm a long way from expert help!)
Wniversal Wiring Harness (to ABC ... 123 the whole process a bit)
Other wiring bits for MS (tuning cables for laptop, link to relay board)
Swirl Pot (Needed to ensure fuel supply as series tanks have no baffles,and off road angles can cause starvation)
Bosch Fuel Pump (High Pressure Type, model no later)
Various GM sensors & connectors (air temp, coolant temp)
Innovate Wideband O2 sensor & gauge (wideband allows more accurate & continous improvements to the fuel / air mix.
Some other bits i'm sure seemed necessary at the time, will add to this list later.
So I researching the MS side of it, and some of the diagrams and explanations seem quite sensible and doable but it does elevate into some serious geek speak which I'm still deciphering.
I'm organising some brackets and things and will try and post info / pics of the build as I progress / kick things around in frustration. There will be some special connections for the throttle and the fuel system, but let see how we go.
I'm especially excited by the fit of the injector body, its butterfly throat mimics the existing manifold aperture near perfectly so the low down torque should be retained without dumping excessive fuel.
till later
