Oh I see. So thats why you had an external coil on 94 electronics.
So the simple solution to this issue would be to just swap to a Cali spec distributor and coil, and you could easily run Megasquirt or any other EMS with sequential injection.

You mean this?

That's what I've been saying. Either you get that, or you get a crank sensor setup from the last revison 5s/cali-spec obd2

Yeah, pretty simple solution. I think its a better way to go than the crank sensor setup since you don't have to take off the crank pulley and lower cover to get to it.
Then just get a DIYPNP kit, and use a 33 or 51 kohm resistor to bring the signal down, and everything will work. Id love to see someone do a 5sfTe setup like this.

interesting. Im wondering if this might be a problem that the FIC is having. It is constantly fighting with the stock ECU

Most likely.

Thanks for this write up, it makes me glad I have a '91 5SFE without the 98+ distributor brick

I am building a 5SFTE MR2 and i'd like to get your opinion on what the best ignition option would be for somebody that is using an AEM F/IC piggyback. I ask because this thread seems to focus on standalone EMS systems so far.

I also made a different thread about adapting a motorcycle CDI system for a 5S, just to explore the possibility.
