Hey guys,

       Been a while since I have been on the forum. Anyways my engine is cammed, and every since the stock Bosch Jetronic fuel injection system had problems running the cam. Cold starts were near impossible, and mid-range throttle was never happy. I messed with it for well over a year but made the decision to go a different route.  I decided to switch over to a new ECU and engine management setup. I chose the STM PRO because almost no material was out there on how to do it, and I find it to be a very capable ECU for sequential fuel injection. If anyone is considering swapping over to an aftermarket ECU, I highly encourage it. It seems super daunting at first to try and figure it out, but if you read lots of material, the fundamentals become very easy to understand, especially how different sensors and such are wired. 

       Anyway, I provided a manual on how to put the STM PRO in your Datsun 280z. It is pretty comprehensive, but it is almost impossible to cover everything. It also references many links that you may find useful. I did make a wiring diagram, which I don't believe exists anywhere else for the STM PRO. It is specific to my setup, but you can tweak it however you need. Hope this finds someone to be of use for! The manual is listed as an attachment.

PS. Special shout out to Pro TunerZ for setting me up with the STM Pro and all the other items that I bought. Everything was very high quality and I was very impressed.

Actually speeduino is different from ms3 is a number of ways. The ms3 manual is good background but  also read the speeduino manual.

@jonbill Of course, that's the goal. I left links in the document to read both (I will move one to the top so it is easier to find), as they are very different, both hardware and firmware. In addition, the STM Pro is by no means a standard Speeduino. It uses a completely different microcontroller (STM32) instead of the typical Arduino or other similar microcontrollers. The components on the board are also quite different. They only share the same firmware and software. Users will definitely need to do their own research on respective ECUs as their manuals are typically dozens of pages. I am not going to explain something in detail worse than what has already been written, thus why that section is severely oversimplified.
