This is my first post and I have to admit I don't meet the "profession" requirements offered while joining. If my participation is offending to anyone please let me know and I will withdraw from the forum.
To keep this post from becoming an essay of explanations my goals are ultimately to find a way, if possible, to get the different CAN BUS protocols that were used over the years to communicate with each other. Pre-Can BUS era cars are getting harder to find and often financially out of reach to the average car enthusiast. A lot of devices have become available in recent years to make CAN BUS era vehicles accessible to building but they all involve removing perfectly good harnesses and rewiring.
The current vehicle I'm working on is a 1999 Ford F150. The original protocols of the truck were J1850 PWM and ISO J9141-2. The new crate engine's PCM's protocol is the current mandated ISO 15765. The new engine and PCM work fine but I believe there has to be a way to get the new PCM to communicate with the older control modules so all the original electronic features of the vehicle can be used avoiding the expense of replacing each system individually. This includes everything from the ignition, instrument cluster, ABS, Air Bags to simpler circuits like "Door Ajar," and obviously many more.
I've found products like the ELM 327 which will translate protocols and devices that will capture one frequency or baud rate and retransmit at another but I haven't received any responses from anyone about how these devices can or if they can help me with my goals. I have talked to people who are in the custom ECU business but so far their interest has been limited to engines and engine performance. All they've told me is this can't be done and I'm not interested in building race cars anymore.
I know a lot of people that built cars for years and have just given it up because of the mandated CAN BUS mandates. It's a shame. I would appreciate any thoughts or advice you professionals can offer about achieving my goals. I'm a disabled vet so time isn't an issue for me and I have a masters degree in Economics and was working on my PhD so although this may be new to me I believe I can learn and understand what will be required.
Thank you, Don.
