While it uses an oxygen sensor for optimal calibration, it will operate just fine without one if you do the calibration using other means. The tables may be edited in Excel.

I have recently been looking into an upgrade for my AMC 258 I6. It has become clear to me that the only way to economicly do it is to do it myself. I have looked into Howell's kit and it looks pretty good (aside from the $1k pricetag). I called up and tried to order just the GM -> AMC intake adapter and they would only sell it to me with their "harness" and PROM. Here is my 1st question - They charge $350 for their harness and I asked them why it was so expensive they said it was due to the filter for the RPM sensor. What is the signal needed at the computer and what kind of conditioning would I have to do to the signal off the negative side of the coil? I also plan on getting an adapter machined (unless there is a better way?) but I don't know how crucial the design is. My thought was to take the shop the old Carb and the new TBI and have him machine me a 1" thick plate, putting recessed holes for the plate to manifold mount bolts and threaded holes for the TBI to plate mounts. How crucial is it to taper the TBI hole to the manifold opening? Are sharp edges ok or does it need to be smooth? Last question is about the PROM. I will probably eventually write my own prom but initially I plan on using the prom from a 4.3L GM donor (post '87). Will it adapt to the 4.2L AMC motor ok? I would appreciate any help and suggestions for improving my approach as this is a new thing for me.

I have an 84 944 Porsche with a Bosch Motronic FI.
Someone is trying to sell a UEGO in the place of my stock BOSCH EGO = sensor=20 saying it is better.
Considering the differences in the 2 sensors, I don't see how it = can even=20 work much less work better.
Has anyone tried this and how is it working?
 
Thanks in advance,
