rkde Posted December 27, 2021 Report Share Posted December 27, 2021 Hi, I'm assuming the answer being no but let's try. Currently with the OEM CAN selected in the configuration the ecu provides enough information to run the dash features unless fitted with a chrono gauge where looking at the CAN capture is providing a 0 where it should be oil pressure this will be the same for the oil temp My thoughts are, ideally I'd like to be able to change the CAN database file to change the information output. I can find the file to modify so assume it's part of the firmware? Or is there a file to change? My assumption is the only fix is to turn the oem CAN stream off and use the second CAN output and configure the data to match what I need?

Adamw Posted December 27, 2021 Report Share Posted December 27, 2021 You are posting in the V series forum so I assume you have an old V series ECU? The OEM CAN structure and all relevant math is hardcoded in the firmware. We stopped developing the V series in 2013 so we will not be doing any future updates for it. We have always advertised the Mini ECU as "Chronopack not supported". The user CAN in the V series is quite basic and wouldnt be flexible enough to build a custom stream to duplicate the OEM stream. On the other hand if you have a current generation ECU (G4X) then we would be happy to add the chronopack messages to the CAN stream if you provide the info. rkde 1 Quote Link to comment Share on other sites More sharing options...
rkde Posted January 17, 2022 Author Report Share Posted January 17, 2022 Hi Adam, Thanks for the response, yes sadly this is on my aging Vipec V series which runs the engine very well. I assume you will not let loose the firmware for people to change? Does have some very off CAN system for sure, when I set the PID to lets say 100 it outputs at 60?? I am not after help with that as I can sort it. I can provide the information for the chrono as that would be good to use considering the gauges are there. If I were to move to the G4X would I be able to take my vipec settings and transfer them over, I am happy to buy a new ECU but I don't want to go through all the mapping and set up again as it works well as it is but for sure it is ageing and it shows when I try and do simple tasks that can't be done... As for the CAN for chrono I am happy to share this data. Quote Link to comment Share on other sites More sharing options...

Are you sure you are not getting confused between decimal and hexadecimal? Decimal 100 would be 0x64 hex. 9 hours ago, rkde said: If I were to move to the G4X would I be able to take my vipec settings and transfer them over, A lot of it will, stuff like fuel and ignition tables etc can be imported. But there are many new features and functions in G4X that werent in V88 that would need to be set up and tuned from scratch. Idle control for example is totally different with ignition and throttle both influenced by the same function. 9 hours ago, rkde said: As for the CAN for chrono I am happy to share this data. You can PM me the chronopack messages and I can pass it on to the firmware team to look at. From memory it is only the oil pressure that doesnt work right? Do you actually have oil pressure connected and reading in the ecu? rkde 1 Quote Link to comment Share on other sites More sharing options...
paulr33 Posted January 19, 2022 Report Share Posted January 19, 2022 Probably doesn’t help but I have vipec v44 working with CAN streams to a plex usdm 102 and a heap of outputs working already. Have you purchased the chrono already. The plex product is very flexible, end less options Also don’t forget some of the number so out of the v44 need an offset so I think the temperature ones are off by 50deg. The VTS help file tells you the offsets. So if oil temp is 100deg the packet will say 150deg because of the -50 offset rkde 1 Quote Link to comment Share on other sites More sharing options...

This will help As for upgrading it is a pain to have to upgrade and at this moment I have took a teensy with a CAN transceiver, taking the data in over other PID and then merging the CAN back to the chrono. Bit dirty but at the moment is works though I had to switch off the CAN frames as R53 and use the second channel. I will look at the options for changing as I would really like to use my COP I had wired for the car before I realised it wouldn't work...

rkde Posted January 26, 2022 Author Report Share Posted January 26, 2022 Just purchased a G4X so when it is here I will get the information popped over to you and lets see what we can do. I have had a play with the software and what can I say it is so much better and more configurable Quote Link to comment Share on other sites More sharing options...
rkde Posted January 26, 2022 Author Report Share Posted January 26, 2022 I have the chrono and I can drive it from my CAN module on the desk and with a microcontroller. As there is no ability to offset on the vipec I am feeling very limited on what can be done and as the second hand sale is probably a few hundred off a new unit I may as well change - hopefully the G4X can drive my VAG COP this time round...
