Who wants to Megasquirt, full sequential fuel/ spark a 68 charger! This Guy!!

[shawge]

Thanks! I know my idle, red line, and HP/torque peak values at RPM. Not so sure about the KPa load at idle and peak HP/torque.

Any guidelines here?

I have completed my first set of Coil Brackets. What do you all think? Is anybody interested in a set? These bolt on using the top two valve cover screws. The spacers are 2" long. I have the coil terminals and boots so that you can custom make the spark plug wires.

Will the brackets work with the LQ9 truck coils?

I don't have one of those coils in hand but from the looks of their design I would say no

I have completed the install of the turbo. It was installed behind the rear axle. I had removed the gas tank a couple of years ago and installed a fuel cell in the trunk so this made room for the turbo where the gas tank was. So the turbo is hung the exhaust is run back to the turbo the waste gates are installed and the cold side is headed back to the front. As you can see in this picture the Blow-off valve is installed and pluming is complete to the intake.  So the next thing is to connect the boost control lines to the waste-gate and control valve and figure out how to control it from the Megasquirt. I've been driving the car making sure the oil returns to the motor properly so far so good

Got my Manifold.

That AC compressor looks too close to the where the throttle body is going to sit. Is there clearance?

[alfaitalia]

That's a great looking motor...engineering porn to folks like me...lol!

[Derwud]

I hope that T/B clears the compressor..

Can't wait to get it in the car..

[Derwud]

What specs or style injectors should I be looking into?

[funknut]

Siemens Deka 80 lbs are a solid bet.  If you're buying them off ebay, beware.  Lots of knock-offs out there.

Just a thought the Ross Machine Racing Throttle Body can be ordered with CW or CCW rotation of the bell-crank that way the bell-crank can be positioned on the passenger side of the intake. The 90mm version bolts directly to that intake.

I've recently set up megasquirt to run closed loop fueling. I'm pretty tickled with it because the last two times I've been to the track I have not needed to make any changes to the fuel table it runs exactly what I have in the table. Prior times at the track it would take 3 passes to get close. Now its right on the first pass. The car ran 10.94 its never run that fast through the mufflers.

I had to rotate my ac compressor toward the valve cover and modify the bracket to clear the throttle body, but it fits.   I have v belts, not the serpentine.

Good luck,

Dan

I have 4 complete sets made if anyone is interested. It does not include the boot set for making custom length wires.

[Aussiemadonmopars]

Hey Mechtech, those coils look way different to the ones that I'm used to seeing, are they the extra high voltage ones?

[shawge]

They look like the D585 coils.

[MechTech]

Yes they are the D585 coil. I like them because of the heatsink. Part of the reason for my bracket design is to get them away from the heat of the valve cover and exhaust manifold. I have them listed on Ebay if anyone is interested.

[Aussiemadonmopars]

Out of interest, has anyone looked into the injector timing? i.e. the timing of when the injectors fire with the intake stroke and when this happens. Just chatting with a mate here and apparently the Megasquirt 3 units have this function built-in but hardly anyone uses it. He has an excel program that automatically calculates it out for you based on bore size, stroke, rod to piston ratio's, etc. looking at piston speeds and so forth. Am I playing catch-up here?   

[MechTech]

I have looked at that a little. Ive only changed the point when the injection cycle starts or stops. Pryor to installing the full sequential setup I ran batch fueling (four injectors fired simultaneously ). I have not seen much difference in ETs at the track. What is your buddies experience

[Aussiemadonmopars]

Some tuners here have looked into it. It's only useful on sequential setups. They have seen gains on the LS motors of like 30 hp on 400-500 hp NA engines. If you want the excel file I can send it to your email address. Its only a small file but contains some useful information. The excel file also references the website: http://www.lmengines.com/piston-speed-calculator/.

Now with traction control....

[cbrestorations]

im debating going megasquirt or fast stand alone for my 6.1 hemi setup. which would you run? i think the fast setup is more dummy proof

Wow, awesome...

Can't say from personal experience too much but I have a Holley sniper self tune set up on an A body big block and I have the USB cable to be able to login in with a laptop. I would say it's not the same but similar. Megasquirt has a lot more functionality, like being able to change injector timing in the engine cycle. Once you get into any software and start using it, you get used to using it and get to know it. The Tuner Studio software on the megasquirt systems looks fairly basic and would be easy to use, a lot like the Holley software.
