Been hacking away at the MFI tuning. It's actually turned out to be a lot more fun to tinker with the mechanical bits than staring at a laptop screen! Although it's a lot more time consuming.
I had it really close (and of course recorded the settings in case I get lost and need to return to a known good calibration) but still a bit of a lean spot. We took a little drive in the country on Father's day to visit the in-laws and show off the car - it ran and idled and drove and pulled like a freight train when called upon, and not a single pop, fart, sneeze or sniffle from the motor. If I didn't have the AFR gauge I would think it was perfect, but still...... a narrow band of AFR's in the high 14's/low 15's even though the rest of the range was pretty rich.
Since I was out of adjustment on the white (mid rpm) screws I decided to lean out the idle, black (low rpm) and main rack, still only a few adjustments into this experiment but it seems to be working. During one of my adjustments the little leaf spring on the end of the spring capsule worked it's way loose, so I had to yank the pump for the 3rd or 4th time. Here is an uncharacteristically clear view of the end of the spring capsule.
The result of all this fiddling:
I've also been working away at the fuchs - here are three of them bead blasted and nearly ready for ceramic clear:
And the 4th with the anodizing stripped and ready for bead blasting:
I will be Ceramic Coating the black accents on the wheels so need to mask (the paint pour method is a no-go with Ceramic) so I devised a method to mark the wheels so I can accuratley mask the outline to replicate the paint-pour contours of a factory fuchs. Here is my prototype:
The final version and some results in a few days.....
