Something like that. With aftermarket LPG the system uses the standard petrol maps and injector drivers to drive the LPG injectors. So the PCM always thinks it is delivering petrol. The aftermarket ECU manages the injection length to manage the LPG fuel injection close to the PCM petrol map. The fac...

I have a specific use. in the dual fuel cars the PCM sends 41, 68, 12, 0, 0, 0, 33, 33, 0, 0, 70, F0, 15, 0, 0, 11, 0, 0, 0, 0, 0, 59 to the dash for petrol and 41, 68, 12, 0, 0, 0, 33, 33, 0, 0, 70, F0, 15, 0, 0, 10, 0, 0, 0, 0, 0, 5A for LPG. Note the 16th set of numbers change from 10 to 11. This...

That's absolutely possible but not just a matter of reprogramming it. Firstly you would need to isolate the PCM and BCM/rest of car into 2 seperate ALDL lines. That means a separate diagnostic connector for PCM and rest of car if you still want to be able to scan them all. That's easy enough. Next ...

provided all you want a map switch to do is change the spark then that might be acceptable. the problem is, and this is what $12P etc code ended up as, you usually want to change spark maps and AFR tables at the same time, for example, between e85 and petrol, so there are alot of other tables that ...

Nice bit of Kit, Tel me could you program it to sit between the PCM and the BCM and have it repeat the codes sent by the PCM but change slightly bases on an input. eg when the BCM request information from the PCM your device sits between the BCM and PCU and requests the information from the PCM and ...

Can you run a second spark map and enable and disable via a input on a Vy flash PCM like you can on the 12P

Ok whats the best way to identify these extra things? Other than disassembly. I Know that the Pcm tells the cluster that it is on Lpg via Aldl. I also Know that it grounds the tank input to turn the LPG on and I have also been able to prove when cold it uses petrol. The switch off seems to be relate...

Hi just wondering if any body has created bins the issue variations of aldl messages. I am playing with an lpg installation and a VY 060B Bin. I have both a petrol and Lpg bins and have worked out how the system is wired and works. I looked at trying to disassemble myself as I would like to work out...

Yes you are 100% correct. What I would like to have is at min the factory computer drive the ALDL message to switch the cluster to LPG. Ideally i would like to use the factory spark tables and outputs to switch the system on. However the LPG computer drives the LPG injectors from the petrol injector...

HI Is it possible to put in custom data for the"send BCM Chatter" under the "Listen to chatter and send custom commands" window.
I would like to send custom chatter to determine the response from the cluster in a Vy
