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 spent a lot of time futzing with my MPS's (I have two I use to compare) both with an inductance meter and during "road tests." Car has run really well, if somewhat rich based on my wideband readings. Being the slow learner that I am, I was focused too much and too long on getting inductance readings at or close to Anders' values rather than trusting my wideband and the car's actual performance. The pros were telling me this and I should have listened (but again, I'm a slow learner).
The other problems I have is just the variations in driving conditions (ambient temps, different loads, car not fully at operating temp, changing octane, etc.) would make it difficult for me to get reliable info. I need to control all the variables except one, right? That probably means finding a shop with a dyno nearby. |
