Have recently bought a 914 - 1972 - date 12/7 - 1689 cc which is running terrible and produces a gasolie smell. Have tried to tune with the existing ECU and Pressure Unit, but no good results. Found out the ECU has a numer 0280-000-037 and the Pressure Unit 311-906-051B
Presume these unit are not correct for this engine. Anybody could provide me with ECU and Pressure Unit numbers that fit this engine ? (IMG:style_emoticons/default/sad.gif) |

This site is a great resource for DJet troubleshooting:
https://members.rennlist.com/pbanders/DJetParts.htm I'm not seeing your MPS (pressure sensor) listed on the site though, so it may be an incorrect MPS as DJet was used in other cars as well. The MPS can be calibrated for each car though. They are essentially the same and just calibrated differently depending on how much fuel is required. There's an explanation on how to calibrate it on that site as well. |

He describes how to tune a factory-adjusted MPS 'better' to one specific engine. It's not true the MPSs are all the same. Different MPS of the same type but with different part numbers contain a different hardware setup like different springs in most cases. Therefore it's mostly not possible to tune a MPS to another engine model. Maybe you can tune it to one specific load situation on a dyno, but the behavior on other load will not be sufficiant.
