I am looking into making a custom monitoring tool to plug into the ECU. I saw one thread on this, but they were more talking about re-programming the ECU. I just want to make some software to watch things like EGTs and water temp and oil pressure, etc. I plan to connect it to a laptop first, but eventually plug it into a small LCD with some custom software running on a RTOS like VxWorks.
My questions are:
Where is there a reliable map for the ECU (or any other data acquisition points)?
Does it update fast enough? (1/sec should be enough, I am only monitoring)
Is there a want for this? Would anyone buy it?
I am pretty good a SW (masters degree and all) and would make it customizable for what to display where, and make things bigger and more colorful as they approach limits the user would setup. Any suggestions, ideas or sensor help would be greatly appreciated. I will post my progress....
