I have an old solo 1 dl, bought new in 2013. I have a SmartyCam HD.
I want to replace the solo 1 dl with something newer. The replacement must work with the SmartyCam HD.
After much searching and googleing, this is what I THINK is correct. Please correct me if I'm wrong.
1--Solo2DL and MXM are about the same, except MXM can accept 4 inputs for sensors; S2DL none.
(I have settled on these two because above MXM it gets much more expensive, and I don't need 50 inputs).
2--OBD2 connection is poor (not much data and very slow). Car is 1999.
So, can connect them directly to ECU via RS232 cable. (Right?)
3--If #2 is correct, any instructions available for how to connect RS232 wires to ECU?
4--Do I need an ECU bridge or data hub with S2DL or MxM?
5--Anything else I need to know? (I do know that these units are on forever backorder, but I want to be prepared).
Thanks.
