I'm using the VEMS ecu, we share a lot of how our stuff is set up (IE megatune, spark setup, etc etc) Anyways i was hoping someone could shed some light into a few issues i'm having, first off


I'm afraid my anolog to digital converter might be dead or it might be something I need to change.I know that the TPS and MAP share a common 5v reference signal. When I power up the board on megatune the TPS and the MAP range are both at 100% and they slowly drop down consistently together until they get to about here???????:


Question #2
My VR trigger consists of a 24 tooth wheel that rotates at half the engine crank speed which is 12 teeth per revolution. I've removed 2 teeth for a home signal, but i cant get the VEMS to respond to the Crank angle sensor under Multitooth but i can get it to make a response if i list it under "coil type" I'm spinning it at a decent rate too on the table.



...and all of this is going off of Jason Russel's design;
