you should be able to adjust the rpm input frequency to run the system correctly for your needs, it been a while since i worked with megasquirt, but for the sake of fuel injection, v8s are 1/2 speed of 4 cylinders, so you could "mod" the megasquirt for a v8 input tach signal speed to run the 4 injectors.. but just program accordingly.

The oil scavenge pump has just been ordered!
I'm also going to receive my EGR Valve gasket this week from rockauto.com
:D
Woohoo finally moving forward once again.
I just picked up the cylinder head from the shop this morning, they did an awesome job on it!
The problem was 8 leaking valves!!! So they did a complete recondition... new valve seals a good wash and a full resurface for only $374 CAD. Can't ask for better.
Got lots of pics, enjoy :)
The last pic is the best one imo hahah :toothy10:

that looks nice, any idea what caused the bent valves?
Yep, putting in the 1.6L ecu into the 2.0 and driving it under boost.
I thought the 1.6 ecu only had different fuel maps, running megasquirt to control the fuel would not cause a problem, turns out the ignition timing is also different, detonation happened or something heated up alot inside the combustion chamber.
The valves were not bent, those are actually the same valves i had prior to rebuilding the head. No visible valve damage to the naked eye, it probly fried the valve seals, which is why it was leaking and losing compression.
Worked on the car today, snapped a few pics so here goes!
My uber outdoor garage... Soak up the sun as they say :)

Cams and lifters, are those called lifters or pushers... The damm things that push on the valves ;)

God must hate me or something...
I did a compression test after putting the major components required to perform the test back together, heres what it gave me:
Cylinder 1: 180 psi
Cylinder 2: 90 psi
Cylinder 3: 70 psi
Cylinder 4: 180 psi
It's starting to drive me crazy! After all that cash spent into the head its still having compression issues. The compression in cylinder 2 and 3 is higher then before i had the head rebuild (it used to be 60 psi and 45 psi)
The only thing it could be now is blown or damaged piston rings... I'll have to rip it appart again and im going to change the piston rings.
Bastard will not win on me... this thing will run soon enough!
I like that piece of ply-wood if that helps....
How else do you want me to jack the car in the grass? Jackstands would just sink in as soon as you put weight on it.Quote:
