Re: Modding Vy Factory LPG
Thanks you have put another part of the puzzle together for me. I had worked out that the 59 and 5A on the end of the message was petrol and LPG. I did this by listening to the messages and seeing what the consistent difference was when i switched between petrol and LPG. I had tried to spoof the clu...

Re: Modding Vy Factory LPG
Thanks I had sussed the clusters out including the extra wire and setting the hex in table 6 to enable the LPG fuel input. I have a donor VY with Lpg that was running quite happily until some A888888 decide to try and drive in my lane. I just want to move away from the Carburetor style because they ...

Found a section that has Math equation = X-128 I am assuming X is the raw value 0 -256. so the displayed values would be -128 to 128 with 0 being neutral (128 or no adjustment) Is thi...

Re: Short term BLM and Long term BLM
I am messing around with a factory Lpg Vy, Which has a BLM of 50, (On LPG) I was thinking that was high, thats all, so I need to figure out if it is high and weather that relates to another problem. So to understand what "High" is a good place to start is what is the limit. If it is High i...

So my question is wh...

Re: O2 cross counts
No does it a steady rpm, say 2000 If you go out and thrash the living shit (and I mean thrash it, High rpm WOT) out of it it will settle down for a while then it will start to run worse and worse.
Here is some of the data we logged
