I have been brain storming again and think that I may have found a feasable MFI pump for our beloved TIV 4cyl.
Any interest? |

I was, indeed, missing something (ain't being civil fun !). Using CIS parts sounds very complicated to me. If I understand correctly, you would still be using big chunks of an MFI injection pump, so that the wide availability of CIS parts would not be big help from a system wide perspective i.e. you would still need to find an MFI pump to implement the system. Still, if you meet some success, I'll be very interested to hear about it. As far as accuracy of rack positionning is concerned I figured the following eyeball estimation in the case where the warmup regulator actuation lever is used: if 3/8th of an inch is 3 points of mixture (from say, 11 to 14) , and you aim to adjust mixture to within 1/10 of a point, you need resolution of about 12 thou. Not sure if that estimation has any relevance when considering a system that acts directly on the main rack. If you then have 4 to 1 leverage, mechanically, you need approximately 50 thou of resolution. I think that should be achievable. In any event, I'll try my best case scenario for controlling a servo motor using Megasquirt over the weekend. If I'm successful, I will certainly let you know. Michel |
