which way is which ???
just got my FI back together and running (made a *new* harness out of 3 old ones) ... runs great, no more bucking and missing ... now, a question about the FI-Brain Idle Mixture Knob. i turned it CCW and the (warm) idle went up to ~1100, turned it CW and it went down to ~800 ... i set it in the middle with the idle ~900 ... is CCW lean or rich ???

Set it with the engine hot, maybe 15 minutes atleast.
Adjust the airbipass screw to set the idle speed then adjust the ECU knob for the best/smoothest idle speed. Readjust the airbipass screw if its now too high of a idle. (IMG:http://www.914world.com/bbs2/html/emoticons/chair.gif) |

Wow, you used the 2.0 FI brain on your 3.6? Cool! (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif)

actually, it's two 1.7L brains. makes for a sum of 3.4L, which is close enough .... (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Andy |

Ha! Watched 'Man With Two Brains' again last night on HBO or whatever. Great Flick!
But still only 3.4L Won't you be underbrained? (IMG:http://www.914world.com/bbs2/html/emoticons/aktion035.gif) |

i use linear interpolation to extrapolate more brainpower out of the 3.4L Twin-Brain ... The brains were re-chipped and each brain is now controlling 3 cylinders (see pic below). the new chip compensates for the 6% lower brain-power per brain. compared to the price of a '95 993 Twin-Plug Brain, this solution was a no-brainer!

Dude, you should'a run two 1.8 brains! It would have been much easier than tricking 1.7 brains. Mmmm... Braaaaaaaaiiiinnnnsss.... --DD |

naa, i hate L-Jet ... at least the old ones from the early '70s ... D-Jet was much easier to use. and re-chip. plus, now that each brain only has to run 3 cylinders, there was some extra brain-juice in each brain that could be re-directed to make up for the 6% overall lack ... i'm going to have the first Twin-Brain 914!

Are you getting the 1.7 running Andy? How's it going? Let me know if I can help.
What's the timeframe on the 3.6? |

Andy, hold everything. Found a brain that will work for you without any modifications.

damm, that's the brain i was looking for. checked with all the usual places, but no one had any good used "ABNORMAL" ones lying around. they are hard to come by, i hear ... that's quite a find! how much $$$ ??? if the price is right, i'll buy it from you!

Actually, this is not so far fetched. Some of the very early Fuel Injected Mercedes V-8s used 2 4 cylinder D-Jet systems. It used a special set of trigger points with 4 contacts on it, and 2 complete throttle switches and MPSs.
I actually worked on one way in the past. It was a beast to get to run right when one of the MPS units blew the diaphram..... |
