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. |

As long as:
You have a stock grind cam with your 2056 the 044 ECU is fine. The 049 can be adjusted to run with the 2056 no problem as it can be reset to the 043 specs. The 007 can be adjusted too to run with the 2056 IIRC If you have a nonstock cam like a Raby 9550 or a Web73 only the 049 can be adjusted to run with the 2056 because it doesn't have the inner cast stop ring in the cover which limits the amount of travel/adjustability for WOT Make sure you have the correct 012 CHT! |

I have not had success in recalibrating the 1.7L MPS's due to their shortened calibration range. I have found even the 2.0L to be at their limit when recalibrating them for a 2056. |

Yes, I add the inner spacer to 049's if going to 2.0l specs but the difference between a 049 and a 043 is mostly at WOT. For a 2056 a stock set 043 works but should be checked with a O2 wideband. |
