Connect 2 devices to the CAN-bus?
Hello
Recently, I bought myself a HP tuners MVPI2.
I own a 2015 Silverado 5.3 V8
I have some experience with the RT tuners software, so I thought it would all go smooth...
Run against an unexpected problem thow....
Here in Europe, Gasoline prices ar about 1.5? for a liter, what compares to about 6$ a gallon....
For this reason, most of the V8 engines run on LPG, a mixture of propane and butane.
This fuel is injected by an aftermarket system, that I recently have installed, so it is a complete new, modern system.
The truck runs very well, but I noticed that it still has a little more power on normal gasoline
Because it runs on this LPG most of the time, I wanted to log the data while running on LPG, so I can adjust the parameters in the ECM.
It will run not as economic on gasoline then, but it will run perfect on LPG.
The problem I encountered is that this modern system, also use the CANbus.
Since it seems that only 1 device at the time can connect to this CANbus, the LPG system dont want to turn on anymore, after the HP tuners is connected...
Is there a solution for that?
grtz, D
