So my 2.4 is fresh -0 miles with only start up minutes on it. I rebuilt the carbs and powdercoated the steel air filter assembly and replated all the hardware and am really thinking of selling the setup in favor of running a 3.2 fuel injection setup on likely with an aftermarket ecu as I don't think the dme will work well with my setup..
Any thoughts or experience with what I am proposing? Now note that I have done this on a 3.0 before with good success just no experience with a higher compression low displacement solex cam engine.. Thoughts? |

@Mark Henry - what would that sort of set up cost?

Mark it looks like something that would be perfect for me.. Once I get all the 3.2 intake system in place I will need to check this out more in depth.. One question though does it come with injectors?? I didn't see that on their website.. No system does, they do sell them separately, but you can find them cheaper. Same sort of boat I'm in...trying to figure out either PMO 46 or engine management system. 3.0 liter, 9.5 CR, same cams as Mark. Not sure what Ben was referring to with carb changes depending on temperature. I never had a problem... in cold, just press accelerator pedal a few more times to get it going. Then it'll run bailky for 5 minutes until warm. BTW, most of my experience is with small displacement Solex and S cam engines with Webers. This is where it gets harder to tune than Ben's app. ITB's and large duration cams have a very poor vacuum signal that the MAP sensor needs to read. My T4, 2.6, hot cam, 46mm ITB's, I could never get a good enough vacuum signal to run on the MAP sensor so I have to run TPS only (alphaN). In very simple layman terms the MAP sensor acts like the a carb accelerator pump, poor vacuum could be loosely compared to a hole in the accelerator pump diaphragm. As soon as I gave up on the MAP and tried TPS only all my issues disappeared. (BTW I just know someone going to argue that the MAP isn't an accelerator pump no matter my "very simple layman terms" statement. (IMG:style_emoticons/default/rolleyes.gif) ) http://www.sdsefi.com/prices.html Ben's application, fuel only Em5-6D (includes harness) $1115 options needed 1 bar MAP sensor $73 TPS $90 Bosch 12X1.5mm Temp Sensor $39 I'd also get a fuel pump relay $30 Optional fast idle, $100, I didn't get this 10-30 seconds of holding the throttle and then it idles. other items needed -Injectors (new style injectors will need fuel rails, not sure but the 3.2 rails might work) -intake and TB(s), (stock will work may need sensor bungs welded in) -FI pump (stock FI will work) -Pressure regulator (stock D-jet will work) -WB O2 meter or at least the sensor (SDS does read through ECU so gauge is optional) -return fuel line. Likely I'm missing a few items. |
