    Firing order change on the A9L

    Is it possible? I'm not saying that it's the best idea for performance, or the best idea for anything, but I'm just curious if you can reprogram the A9L/A9P to fire like a lo-pro. It would be neat to see how it pans out.

    Also, is it possible to program for 14lbs injectors?

    My worst enemies are those who presume me to be harmless. They cannot imagine how much I resent and disdain them, or just how great a threat they would face if I could get at them. Everything in their behavior speaks of insult and presumptuousness, and for now it is all I can do to make constructive use of my anger toward them. At this time, I just make a list of them and keep a watch on. Some day, with the help of time, space, and circumstance, I will be able to humiliate them properly - not in a manner they would enjoy, but in a style calculated to make them wish that they had never been born.

    Why bother? Why not chip tune the lopo? You could repin and tune the A9 ECU I guess....Kind of a waste of time when you can get alot of the lopo ECU without doing mcuh of anything to it. If you want mass air find a cali car lopo ECU and use that.

      I definetely want MAF. Unfortunately, we are in kinda a shortage of box TCs 'round here. And we don't have kali TCs here. How is the lo-pro tunable? There's no J-5 port is there?

        You can not get performance from 14lb injectors.
        You can switch the pins around to match the firing order of a standard 302 if you wanted to use a performance 289/302 cam that did not have the HO/351W firing order.

          Not wanting it, really.

          Want to use the stock lo-pro cam. Anyone have a wiring diagram by slim-ass chance?

              What is your motivation for going MAF if you are not looking for better performance?
              The money that a chip would cost you would not justify your results.

                I did the mas conversion with the lopo cam and a 9al ecm. On my blue 2door.
                used the bigger mustang tb. Had to change and add a couple wires at the ecm connector. Had to use the 19# injectors. ran great got good economy. if i remeber correctly had to swap # 3 and 7 injector pins, and # 4 and 6 injector pins at the ecm connector. disconected the vacuum hose at the map sensor. the added wires cam from the mas meter. realy the worst part was adding pin holes in the ecm connector rubber seal kept f in up the connector pin locks in the female part. used the 5 spd ecm runs better than the automatic one with the retard feature. moding the tb to reverse the throttle and tv cable anchors think i weled up one hole and drilled new locs and used a holley carb bolt on ball. tappered the egr to match the bigger tb to the merc upper.

                    Wow turbo you did the TB swap the hard way...


                    Roach, why do you feel the need for a MAF? I ran 16 flat with a lopo, and was doing 14's with a SD mustang HO setup...Ran great and got 24mpg.

                    And I don't see a post by freashmeat in here?!?

                      all the parts were free
                      so it felt easy in the hip pocket

                        MAF is just more efficient and easier to work with. I can add boost/larger TB/aftermarket intake later on without having to tune too much (if at all).

                        Sorry. I was on the sauce last night.



                        Thanks for the awesome response Turbo2256b. I have been inspired!

                          So were mine.. Just a bit less work for me.


                          Roach, I don't know what your plans or goals are for the car, but if you want it to run well for cheap and get what you can out of it, here is a tried and true reciepe.

                          2.25" or better duals with aftermarket cats, mustang headers, 60mm TB and HO upper, some 3.55's or better gears. Ditch the smog pump and mechanical fan, get an electric fan. I ran 16 flat with a similar setup.

                          Then you have a great base for when you want to toss on some E7s, the 19lb injectors, a HO cam, and put an HO ECM in.

                            I am big fan of speed density. Just look at my sig. Im running quite a few mods with SD and it runs great. and many of those mods effect flow, TB, intake, ported heads. it can take it.

                              ok, here's the thing...
                              I plan on putting in a set of 24lb injectors and converting to MAF...
                              I plan to buy the MAF ECM from N A...
                              but I hear that Mark VIII's have 24lb injectors and MAF.
                              so, here's the big Q:
                              can I put in N A's MAF ECM(A9P), 24lb injectors, the MAF meter/sensor from a Mark VIII and have everything in balance?
