Arduino TCI

[Team Junk]

I plan on cross posting this to the Gonzo development page

Standard motor LX-226 Most fuel injected Fords 88-97.

Ford escort And v6 Rangers are plentiful in junkyards and peoples yards. Look around they can be cheap online.



Ignition module for the Ford EEC-iv FI system.

This system uses hall effect pickups .

Somehow the SPOUT signal from the ecu varies the timing. Don't know the mechanism of how it does that.


Will have one in hand soon to see how it does with pick up coils and magnets. And play with spout signal.


Main thing is it takes care of most of the hi powered coil and pickup functions on the analog side. Easy to heatsink.

Its smaller than you think from the pictures. Early ones attached to the outside of the distributor. And died in huge numbers because of the heat.

The ones made after the turn of the century should be fine.

Hmm. Interesting. I am currently breadboarding a different design for a TCI. I read an article last winter about the merits of analog computers and how they are still used today. Got me thinking about a different TCI module. The arduino design I have works, but I don't have a lot of confidence in my own coding.

Fine work is there adjustment possibility for the advance .. I get a feeling it is a bit late on this video.
But difficult to tell on this short blipping .. is it the same as with stock TCI

Well the audio quality isn't that good. I suspect most of the current issues with the bike are more to do with fuel/air. There may be a slight air leak on one or both of the boots going to the carbs. I get a little backfiring when I am out riding/decelerating. As to adjusting the advance, that would require making changes to the code, which can be done on the bench, but not on the fly. The way it is right now the advance is pretty close to the spec in the yamaha shop manual. 16 to 41deg between 1900 and 3300 rpm. Actually the bike accelerates quite smoothly through those rpms. At idle, it should be firing right when the second pickup pulse comes in which is normal for all TCI bikes.
