So this is the equivalent of a SMC?
It's known as an SMD PnP but I can get more details if required.
What car did you have this in and what version of the software is it?
I had this ecu in my GSR but my car runs a complete evo loom for not only the motor but the chassis also. I can get you the software version tomorrow, I will have to plug it into a mates car and hook the laptop up from mem.
Does it have idle stepper control?
Yes
Do you have a picture of the top and bottom of the board or can you get it?
I can do this tomorrow for you
