my setup
gen III 3sgte with autronic ecu + individual audi 1.8t coils (the stable year versions). Each coil has its own built in igniter and 4 pins: positive from switched connection, signal ground, ecu signal, and power ground. And the coils are TCI coils, not CDI, not that it matters. I'm getting tired of not having a tach signal so I'm hoping you guys can help me figure something out aside from running 4 diodes in-line with the signal ground and jumping off one of the coils to run to the tach. 1mz tach I was hoping I could read up on how it was done on the 1mz swap which has a 3 coil wasted spark setup, nada..the 1mz swap just requires the gauge clusters to be disassembled and mixed together to work. mixing audi and toyota gauges My initial plan was to mix the audi gauges with the celica gauges and use the tachometer output from my autronic as the tacho signal, not going to work unless I recreate the circuit-board for the audi and wire it into my celica. I bought the gauges off of the same kind of car the coils came off of, but they are all driven by a signal from the ecu it looks like, not to mention it's just one big circuitboard. running only audi gauges I've also thought about running the audi gauges instead of my celica gauges, BUT I would have to wire me speed sensor and fuel level sensor into the autronic and run outputs to the gauges. using a tach adapter Now I'm wanting to run the tach signal off of the autronic to the celica gauges. Is there an adapter I can buy? I can configure the autronic to run a normal tach output or invert the output to the tach as either a .5 msec pulse or 1 msec pulse, nothing else. -------------------- -Jay

Sorry to bring a thread back from the dead, but I am doing a st215 swap and would like to get the tach working, I would like to try the resistor mod has do you think this would work for the out put from the stock st215 ecu
I am also having a issue with the temp sensor spiking at a low temp. IS there a mod for it? or am I going to have to drill and tap my old sensor in the water neck somewhere? |
