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. |

Hey Rob, I'm no DJet expert but I think there are som issues here.
An 049 MPS is a 1.7L MPS. It cannot be recalibrated to the needs of a 2056 engine. The 044 ECU is the 1974 2.0L ECU and that should work for the 2056. You need an 043 MPS that is recalibrated for a wider pulse width range than the standard calibration, not the 007 MPS (is that a 1.7L MPS also?) The 1.7L MPS does not have the adjustability range of the 2.0L MPS's because it lacks an internal spacer. Almost all MPS are adjustable, a few of the earliest MPS for early D-Jet VWs and Benz's are not, but they are not in the 914 dialogue. |
