Getting everything together to install a 2056 into my '72 and swap out the steady, reliable 1.7L I've been running. The 2056 is '73 but came with '74 ECU/MPS combo. The part numbers are 049 on the MPS and 044 on the ECU. Sometimes I'm not sure if I read that ECU/MPS compatibility table on Anders D-Jet site correctly. Is the 049/044 a winning combination?
Also, I've read here that a 2056 really should run with an adjustable MPS. A couple of months ago I converted my 1.7L MPS to adjustable with the Tangerine kit. Any thoughts on whether I could effectively run my MPS (007) just by adjusting it appropriately, or are there other compatibility issues? Or do I need to make that '74 MPS adjustable? Thanks for the help. |

There are 2 ways to increase fuel flow, everything up to know is dealing with longer pulse width for injector opening.
Another way is to increase fuel pressure. Remember that flow changes not linearly with pressure, but with the square root of pressure change. Thus if you want 5% more flow,you need 1.05 squared pressure change, or about 11%. Of course this increases flow over the whole load range by the same amount. Not sure just how much more a stock pump can put out, bout the pressure regulator can easily be adjusted. You'll need to tap in a fuel pressure gage to know what's going on but that's easier that modifying a MPS. Barefoot |
