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. |

Those numbers sited on the Anders' site are targets based on his sampling. And there are going to be some differences in LCR and O2 readings across different setups. I think there may be various opinions about how valid those numbers are.
Still, I guess I'm a little surprised if someone that knew what they were doing set an MPS based on those values and it required that much adjustment to get it in line...but I guess it's possible. It got you close enough so you could then dial it in based on Air/Fuel readings, which is what you should do anyway. The other MPS you repaired - I can only guess that you didn't put the inner and outer screw back close to previous measurement despite your best efforts. That's really hard to do, IMHO. Why not buy an LCR? There are cheap ones out there (~$40) that should get you ballpark. |

You are probably right, the outer screw or maybe both are not where they should be. I may play with it just a bit more, I was just surprised it wasn't close enough to at least run. |
