Dakota Digital BIM-01-1 vs BIM-01-2 to integrate to LS ECM?

[samckitt]

Can I direct wire it to the ECM & not use the ALDL connector?

I have the 01-1 version. Why are you trying to wire it in vs use the ALDL plug?
Just curious.

Originally I wanted to wire it direct so that it was open for the cruise control, or wire that direct too so the big plug wasn't hanging off the end, or whatever. But, I found out that my ALDL connector doesn't have the BUS terminals required to transmit the signal to the BIM module. So either way I have to run extra wires for it. So I'm going to go directly from the GMPP harness bulkhead connector to the BIM module, ±12v and ±BUS circuit all from the bulkhead connector.

I am going through something similar myself. I have an OBD Y cable connected to my gmpp ALDL connector. The VHX gauges run fine off of the Y cable. I am getting ready to add the cruise and DD said the other Y connection will work fine.

The only issue I have ran into so far was the other day. I bought an ELM27 OBD dongle and wanted to use it with me iPhone track addict app on my iPhone. With the VHX stuff connected the Elm dongle would not read. After talking to DD yesterday, their Tech Dept told me that you have to change the channel on the DD obd bim module (in the big instructions). Apparently the PCM doesn't like 2 devices using the same channel to try and "read" it.

Can you run the jumper wire from the cruise control module to the BIM-02-1 module & not use another ALDL connector?

Not sure, I would call their tech dept about that one. They were friendly the past couple of times I have called.

The BIM-01-2 came with a 4 wire jumper to go from it to the main DD "brain". The BIM module has another connector for another harness that I would think can hook to the cruise module. Thought I read somewhere that they can be daisy chained together.

Yeah, after talking to them I will be upgrading to the -2 version of the BIM module when I install the HDX gauges in a couple of weeks. They said the software in the -1 version is outdated and probably wouldn't be able to keep up with the HDX stuff. . When I opened the HDX a couple of days ago, i noticed that they are using a different type of interface wire on this new series. My current VHX ones use a CAT5 wire where as the newer stuff uses a red/black wire to connect to the main control panel.

I asked about the difference in the BIM-01-1 & BIM-01-2 & DD told me:

There is no functionality difference between the two. The only difference is a different style of power input and switch, all cosmetic stuff. FYI we do not sell the BIM-01-1 any longer, it’s possible you can find one from a dealer of ours. BTW I don’t see any advantage using the BIM-01-1 both need power and ground plus the signal wire connected........

Yeah, I bought the 01-1 unit 3 years ago when I did the VHX conversion. I know the old one is no longer available.
