Hey ws6, have you found those pics yet or does that person that converted it have any idea of how long it will take to get his product to market? I am very interested.

 

What if you have a '93 (don't they use batch fire) does your opti still send a low resolution pulse to the PCM ? Or is the injection triggered a different way?

 

The problem is that the pics that I've got are of someone else's setup that I promised that i wouldn't share/post around, and I will not. WRT to if it ever comes to market, I don't really know. To be honest, I don't even remember the guy's email to ask him.

The pics of the one that I did were lost in a comuter reinstall and the car was parted out a while back, so I can't get more.

I'm sorry that I can't offer pics, but I will tell you for sure that it can be made to work.

 

Then would mind sharing how the thing went together? Did you have to modify the cap and put the optical sensor in it and how did the sensor read where the cam was? Did you put the optical disk in the distrubitor?

 

(I’m looking at the pictures of the other setup as I type this to refresh my memory, I did this a long time ago)

The wheel and sensor fit in the bottom of the distributor housing and on the shaft where the stock trigger fit. The rotor and cap assembly is left untouched.

I ended up having to modify the housing some (I remember having to change the base plate 2x to get the sensor to sit flat and in the right spot, but I don't remember exactly what, it was a long time ago, probably '94) and make a sleeve with stop screws to hold the disk to the distributor shaft and make it adjustable. The wheel/sensor are fairly easy to mount, what I don’t remember is what the distributor parts look like disassembled (and don’t have one lying around to look at) so I could remember what had to be changed to mount the sensor. On the other setup it looks like he cut to top of the distributor housing up or off and made his own base plate, but if that is what he did he’s got better ‘stuff’ then most of us (it looks like a factory pressed/stamped part).

I remember for sure that it wasn’t that hard to do, since back then I didn’t have access to anything more then hand tools and I don’t remember having to mooch use of anyone else’s stuff to get it done.

I’ll try to get a good look at a distributor housing to see if it refreshes my memory.

 

Thanks man
Would really appriciate it.

Also, I've never looked at how an opti goes together, but isnt that cam disk that the sensor reads on the crank? If so could you rig a crank trigger to read in place of the cam sensor?
