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

Here is my current .MSQ file, as well as a log file from today should you want to play with the logging function.

I will be posting a fun video here in a little bit.    

Thanks dude!!

Hey Redmist,

Ever think of trying to mill some injector holes into the heads themselves and make a direct injection 440? It would probably be easier with a hemi just because of the shape of the combustion chamber and the location of the spark plug.

[redmist]

Thought about it yes....

I have an Ecoboost, so I have already torn all the sensors out to look at them, and put them back in. haha!!

I know the Megasquirt people are working on DI as we type.  : )

Yeah, a friend of mine I was in the Marines with is a mechanic. He was posting pics of a lexus DFI motor and the heads. I thought it was a second spark plug hole at first. That's what gave me the idea. Fuel pressure would have to be stupid high and of course where in the world would you mount the injector. I think it could work with new hemi's, just use the second Spark Plug hole and modify it to fit an injector. Not sure why they didnt do than anyhow.?? You could run like 15:1 compression

Alright.....   

So, It looks like we may go ahead and do a small run of these. I am going to see what is clearing the 8-axis, and see if we can slug a few of these out real fast. The guys are thinking we are going to blank them out, send them out for anodizing, and then bring them back in for engraving or something cool like that.

Let me work on this a little, and I will keep you guys updated.   

. Put me down for a bushing as well, post me a personal when done , aluminium finish fine with me

I need to seriously look into this, I am sick and tired of smelling fuel when I'm driving.  I would hope the efi removes that little problem?

[redmist]

It does take all the smell away yes, unless you have a bunch of overlap in your cam, I smell some fuel in the exhaust at idle, and thats it. However!! I have been playing with the "Injector Angle" in the tune, and have found that spraying the fuel on the hot shut valve right before it opens not only helps the idle, but cleans up the smell some. Injector angle is set to fire sooner as RPM Increases.

So much fun stuff to play with.

Cool beans! I'd never do it because sensors and computers are the last thing I want near my Charger's engine (unless you count the Mopar Orange box) but kudos for a tough job well done. Just make sure you take some extra sensors along on your trips.

I already got a bunch of extra's while at the junkyard. Some of it is not needed to run the car, if the MAP sensor goes out, I can just run the engine off of Alpha-N mode. If the CAM sensor goes out, I can just switch it to wasted spark, and wont need the CAM sensor to run. If the TPS, Or Crank sensors go out, well dang...    Sorta hosed there. Even temp sensors can be omitted and I could still run the car. As long as I have my phone or laptop, I am good to go! Honestly having all these sensors was the drive to do the conversion, all these sensors are easy to find in a junkyard, or in any auto parts store.   

[bull]

Yeah, the ones for adjustment input can be ignored but it's those pesky "the car won't run without it" crank sensors that will burn you. But that's cool you can use easy to find over the counter stuff. Usually they're just picking up on pulses generated by a tone ring so one is pretty much like another. If you can wire it in it will usually work. You'll just have to carry around some spare parts like the rest of us do. And make sure you keep the batteries on your phone and computer well charged.

Just curious, maybe you mentioned this already but where is your TPS located?

[redmist]

Bull,

It's mounted on the throttle body, in the standard LS location.

One of the guys over at the Idahomotorsports forum mentioned that the TPS is not needed either for Speed-Density, but it does add some features.  I guess the Crank is the one to have extra of just in case!!

ETA: The guys over at IMS shared this link with me so I could post it in this build thread. For those looking to do this conversion, here is a good list of Injector part numbers and those specs associated with them. You can do a CNTRL-F to search the page for your part number if you have one!

glad to see this one still up and running...     glad the trigger wheel worked too   

The bushing for the jeep sensor is an awesome idea.



I'm personally getting out of the old technology -  the 6.1L in my Charger is just getting up and running and my 5.7 in my new challenger is a dream...     I won't miss replacing points, tuning carbs, and dealing with all the other fun that comes with 440s.

Great Info thanks

A little upgrade, and an update!!

So as I am getting into the higher RPM area of my tune, WOW! does this thing pull on the top end! It never felt this way with the carb. After 4000 RPM it frickin goes crazy! I can't wait to see what it does on the track!!

However, we have a problem. And that is Duty Cycle on the injectors I am running. At WOT I am at 95% duty cycle. That's just to high for comfort. Someone posted above that the 2013-2014 Ford GT500 Injectors were now for sale on rockauto, so I order a set of 8 of them.  $210 Shipped!!!

Now these injectors are the same EV14 style that most aftermarket companies modify to turn into 1000cc monsters, but these will work just fine for my application in stock form. They are 55lb an hour injectors at 39 PSI.

And they are CHEAP!!!!

Rock Auto has them listed for $24 a piece, this is what you are looking for:  MOTORCRAFT Part # CM5216

Picture of the Injector as well as the bag/part number




There is one hangup to using these injectors in my setup, and that is the length of them. They are a Medium sized lengthwise injectors instead of the current long style I am running. No worries though!! Injector Dynamics has a solution, and that is little hats for the injectors that extend the length. As found here:

http://www.t1racedevelopment.com/index.php/en/products/details/219/362/injector-dynamics/fuel-injector-accessories/14mm-adaptor-top-for-injector-dynamics-injectors.html

And here is a picture of my new 55lb an hour Bosch style EV14 High Impedence Injectors ready to go for a total cost of around $300!

Not bad!

Plus they look all race carish and stuff.




All I need to do is change my required fuel to reflect the injector change, and my current tune will be workable with these injectors. I plan on tweaking the maps a little though. Basically I will start over now that I have a much better understanding of what I am doing.

[MedPhys]

Fantastic!  Any update on the bushings?

[Steve P.]

Great work and info. I'm enjoying this read a lot... 

[Homerr]

I'm still curious what sort of MPG you can get on a tank with an economy profile...prolly too fun to romp on if now though!

[68CoronetRT]

95% duty cycle isnt all that bad. Most cars are like 85-93% anyway. Our buddy runs 100% cycle in his 1,200hp 5.3l turbo mustang on MS3. No issues yet with injectors....

I even run like 94% duty cycle on a turbo 22re on MS2 that we race in the desert with. No issues ever!

[elacruze]

I'm still curious what sort of MPG you can get on a tank with an economy profile...prolly too fun to romp on if now though!

I've had two tanksful over 23mpg with my 505 stroker, and I have an obsolete Holley commander TBI setup with mechanical distributor. With the full engine control of my Electromotive box (Megasquirt can be functionally equal) I expect to see 25 best and an improved average-we averaged 15.6 or so over 3100 miles on the last power tour.

[grnfsh]

Guess we better snatch up a set of those injectors before everyone figures out they are the one's to have and the price goes up. 

[grnfsh]

Redmist, does the MSIII kit come with instructions on how to assemble? are they easy to follow? Have pictures?

[redmist]

Yes it has pictures, bags are labeled, and it guides you step by step...

Purchase a JimStim 1.5, and a StimX and build those first for practice. You will want/need both of these little devices anyhow, and they are not expensive at all.

Here is the guide I followed to build my MS3X:  http://www.msextra.com/doc/ms3/build_manual.html


Nothing new on the adapters, we have a few first article parts to push out on the gun side of things, and then we will work on the adapters.

[Budnicks]

Great thread  I just got caught up again, thanks for all the great information, I hope you have equally as great success... 

[kamkuda]

Yes 95% duty cycle is a problem.  A buddy ran over 100% and ofcourse went lean and melted the pistons out of his hemi. 
Better safe with a bigger injector

I have 83 lb injectors and may have to step up later if a go with a bigger procharger.
EFI is amazing for tuning.  Lots to learn.

Sounds like you are having fun and doing well.
