Hi there

If you're not getting a boost reading then that could be one of two things. Your car ECU doesn't support the MAP sensor PID (the id used to generate the boost reading), or, because you mention the 5 second delay, there could be some bluetooth issue (this is one of the tell-tale signs of a problem with bluetooth).

I'd like to get a debugging file from you if I may - Torque has an option in the menus (Menu->More->Send commd log debug) that will send me everything I need to know about what is going on with your particular installation.

If you could run Torque, let it connect and get information for the dials for about 40 seconds, then select that menu option and send it, I will then be able to help you a bit more.

Thanks

Ian

Any solution to this yet? I am also having this same issue on a VW Golf which is the same platforum as the Leon Cupra R mentioned by the OP.

Cheers.

It will be probably because both of you have MAF sensors and not MAP sensors and therefore there is no absolute pressure reading available using the standard OBD PID set to generate the boost pressure data.

It may be possible to 'synthesize' a boost value from the MAF sensor, however this is just a rough guess and it probably won't work

Thanks for the reply Ian, much appreciated. The funny part is, my engine definitely does have a MAP sensor, as does the OP's engine also...i did some research on seatcupra.net and other vw/audi forums but it all lead to the conclusion that it won't work for our cars. I just don't understand why, seeing as we do have MAP sensors...

If you have the sensor, then there should be a PID for it to read the value, however it may well either be controlled by the 'dealership' and not 'activated', or it could simply be mapped to a different (manufacturer specific) PID.

Getting hold of the manufacturer extended PIDs or ECU mode information is the very difficult part! 🙂

Maybe thinking too much into it.... is there a way to capture all transmissions that come from the ECU.

End of the day it is just a serial port??? Not sure that even it it were possible tocapture this on a laptop that the output would be able to be made out so that you could convert the values to anything that made sense.

Just thinking out loud?

Yes, and Torque did used to have a 'monitor' mode to capture all that information on the vehicle bus.

It may be possible this way - assuming that information is broadcast and you don't have to request it for it to become visible, however it is entirely possible that you have to request it to see it, and we don't know the code for that - even just browsing the databus won't show us it.

Any further info on MAF boost measurements for VW/Audi vehicles? I've got a 2001 Audi A4 (1.8t) that uses the pre-can bus (KWP-1281) protocol for the engine module.

I know on my old ross-tech vagcom usb (that no longer supports my Vista laptop) I used to get an absolute boost pressure that would register at Denver's atmospheric pressure and go up from there. (I.e. I could calculate a derived "gauge boost" reading by differencing the read vs. base pressure measurements.)

Is there an OBD-II Bluetooth adapter (for my Droid) that might have a better chance of working with future software if the current Torque software can't map the MAF boost PID? I haven't bought one as of yet. (Another wrinkle is that I'll probably buy a 2011 audi s4 to replace my current car within the next year.) Any recommendations for adapter (e.g. OBDKey vs. Kiwi) would be appreciated.

TIA
