Stand alone injection? Opinions? For /6 w ITB, help picking EFI system Options

[TorqueJunkie]

I am in the process of rebuilding my 2.4 engine with 2.2S pistons, S cams, and am going to install TWM individual throttle bodies. I am looking around for some fuel and ignition systems for this engine. I have looked at most of the ones out there, but not sure what works best. On some of the other forums, there is a guy running the Megasquirt(latest version) with good results. Another guy is using Electromitive. I have everything except for the control module. What do you guys use on the flat 6 engines? I do not want to spend a ton of money either. I want something reliable. I hated my carbs.

I have been running a Megasquirt system for almost 3 years. I only had one problem and that was user error. I accidently unplugged device flashing a new tune. This corrupted the firmware. Wasn't a problem to reload, I just could not figure out what the problem was.

btw, MS is a very powerful ECU. It is true that it is not Plug-n-play compared to some systems. However, if you are willing to learn the basics of fuel injection theory you can build a system that is nearly as integrated as multi-thousand dollar systems. The new MSIII is fully sequential fuel and spark through 8-cylinders.

I do not think you need sequential unless emissions are a concern. I doubt your 2.4 is.

btw, While the early S cam is wonderful there are some more modern cams that will provide much better engine performance. Think E torque curve down low and 906 up high. I think you should contact John Dougherty at DR Camshafts. Something like his DC 43 comes to mind. btw, I would have them ground on a 106-108 lobe center. Anything narrower will give the MAP sensor fits for the EFI. You could run alpha-n (TPS) only but the throttle response gains are in speed-density (MAP).

I have set of new in box reground Web-cam S grind cams. Can't see spending $800 more for new cams. I have so much money in parts that I could have put in 3.6 993 engine by now. Problem is that I spent slowly it over 10 years while family and other issues took priority. Still limited on budget, but would like to get it running this year. I miss this car!

Heads are out getting reworked with Aasco springs/Ti tetainers(man these are nice)and valve job and surfacing.
Case is out for : If usable still, then shuffle pin, face spigots, case savers, oil bypass mod, and rods rebused/shot peened. 7R mag case.

Thanks for the tips. I will really have to learn more about the MS III and see if that is something I want to try or not. Any other issues I should look out for in the EFI set-up? Was told I have to tap each manifold for 6 ports for the vac block connection as well.
