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. |

I haven't got much to add, Bleyseng and Bowlsby know more about how to adjust MPS's than I do now! Only thing I'd say is that my LCR data should be used to just get an MPS initially set up, especially with modified engines. The gold standard should be to adjust the MPS while running the car on a dyno with a shop-quality gas analyzer measuring the AFM. Bowlsby and Bleyseng can comment, but my take is to do the main mixture adjustment under part-load at 2 or 3 engine speed settings (e.g. 2000 rpm and 3000 rpm) and set it to 13.7:1, and to do the full-load adjustment to 12:1. I do mine on the road with my less-than-shop-quality AFM and I've gotten good results.
