ok thats a very interesting set up you have. are the intake pictures of your new set up with the motorcycle tb?

Its funny thing that ignition is much easier to get than fuel injection.

Fuel got much more variables.

You can drive with carb and tune the spark map and then get the fuel stuff.

You can do fuel first, but fuel map changes much more if you tune spark map, so spark first is a little bit easier, I think.



My fuel effiency was same with my TBI and old carb version, but I think a worn out engine was biggest problem then.

Power gain in lower RPM's was high and it was little bit hard drive with low stall Cruise-O-matic.

Stall was good in about 300-350 RPM.



New setup with motorcycle throttle bodies and dizzyless ignition got too few miles (about 1/2) so I cannot say much about it, all can I say that fuel effiency is not good as it used to be if lopey idle tells me something(new cam with hard grind may have something with that)



Crane XR-1 is good to trigger pick up and Crane HI-6 or Bosch 139 is good to amplify the spark.

Just lock your dizzy to 60 degree and turn your rotor to point about 25 degree so MS can start to calculate ignition timing from 60 and wide rotor can deliver spark from 0 to 55 degree.



I hope somebody understands this cause something went wrong with my english studies way back, since 3rd grade.

My intake...


I used to have crank trigger like this, worked very well.

thanks for your guys help i will for sure be thinking about such a project as i think the benifits on injection might serve me well for a daily driver. Would you be willing to post up any more details about your intake.

You are free to copy our things . Our single turbo gave us 330 hp with 630 Nm of torque and peak hp came at 4900 rpm. Max torque came at 2600 rpm or even a little below it. Here is that old video from 2008 december. http://www.youtube.com/watch?v=8yFwrPj8SnU

The engine starts easily with efi and wwe have crane xr-i in it's dizzy. LordMrford has a crank trigger in his set up.

wow you guys have just turned this thread into a wealth of information for me. Ive been reading a lot about the megasquirt systems and am seriously considering coming up with something for my 59 4x4. That intake looks really sweet and really doesn't look that hard to build so i might be pirating your ideals if you don't mind. I would really like to eventually control both ignition and fuel with the megasquirt, probably set it up for just fuel and when thats all dialed in hook up the ignition so im only dealing with one variable at a time. What would be the best way to control the ignition as obviously the dizzy isnt set up for it. could you replace the pionts dizzy with an electronic one like msd makes and wire it that way? just curious as i think it would make for a neat truck to have an electrically controlled 292 even tho normally im a points and 4 barrel kind of guy. So do you have any of the systems you guys are building up and running with any feedback on power, ease of starting, fuel efficiency, and so on. Thanks for the replys guys.

MS3 can.

Can Megasquirt do sequential firing of multi-port injectors? The diagram looks to be a batch fire system.

TBI-style fuel-only is pretty simple and is good as 8 point.

I have Megasquirt 2 assembled by myself, but MS 1 is easier and got almost same stuff than MS 2.
Assembling is quite easy if you know anything about electronic circuits.
If you not then you can get a assembled from diyautotune.com like cheapest version, http://www.diyautotune.com/catalog/megasquirti-programmable-efi-system-pcb22-assembled-unit-p-34.html

I got quite new WinXP laptop with USB adapter in my own project, but I had older laptop with Win98 and serial port, which worked just fine. I recommented machine, what can run Tunerstudio, http://www.efianalytics.com/TunerStudio/ , cause that is awesome program to MS tuning. MegaTune is lighter, but not easier. Works still fine.
Mating the MS box to tuning program is hardest thng if you are not computer person, but I hink, TunerStudio is made is easy.

MegaManual is Megasquirter's bible, but it starts to be hard reading for beginner

In simplest of versions, MS EFI needs some TBI-style throttle body like 350 Chevy TBI unit.
It has injctors, pressure regulator, Throttle position sensor(TPS) and all the fittings.
Then you have to have atleast 18 PSI fuel pump (if using not TBI injectors, you need 60 PSI) and return line to tank or surge tank.

Then you need Intake air temperature sensor(IAT), Coolant temp sensor(CLT) and Lambda sensor.
Simplest way is get them from Chevy, narrow band(normal) Lambda is better to be 3 or 4-wire version.

RPM is easy to get from some pointless module in distributor.
And if you want to upgrade to Ignition control too, just lock the dizzy and wire the coil from some coil driver like Bosch, MSD or Crane.

Some wiring example from my project album...

Edit: I found a wiring pic for TBI and simple ignition control, RPM pick up is like four bolts on damper and HALL-sensor but it can take from dizzy too.
