just real quick, what kind of fuel injection should our cars have?

like (letter here) Jetronic?

it is jetronic right?

 

I don't think so, the old 280zx's had a variation on Bosch L-Jetronic, but the system on our cars is way more advanced than L-Jet. It's more like the later Motronic system, except that Motronic uses little sensors on the flywheel to tell where the engine is at by signalling every time the engine has passed TDC, and ours has the crank angle sensor in the distributor and has 360 slits so it knows exactly where the engine is at at any given time. Other differenes are that Jetronic pulses the injectors once every engine revolution, Motronic fires each bank alternately each revolution, and as far as I know ours are true sequential injection, each injector fires as it's cylinder is coming on the compression stroke.

 

Yeah, our fuel injection system is not made by Bosch. I believe it an in-house made fuel injection system, but don't quote me on that.

A local mechanic told me they are OBD1 fuel injection systems.

 

Have Nissan replace them for FREE. There is a recall on the injectors.

 

HELL NO, when i had my timing belt break i was told my injectors were in excellent shape and had never been replaced

i was just curious, i found a book on tuning the injection and it did have a picture of a 300zx but the book inside only shows generic things so it wasnt car specific from diagram to diagram
