hello, I'm having a problem with my tune, audi a3 tfsi 2.0 2008 manual, I did a tune in this car and it worked perfect without errors and without codes, but after driving just over 100 kilometers the car goes into emergency mode and generates an error of checksum p0601 and it stays like that until I record another tune, then it unlocks and works, I changed a torque monitoring table, is that what is causing it?

Have you tried going back to stock and seeing if it happens?
I haven't tried it, when it was original there were no problems
If it was me that would be the next thing I would test. Otherwise you can try to reach out to support and see if they can assist.
the car is running now with the tune i made. I had changed torque monitoring tables, I removed that and also a change in the idle and I didn't get this error anymore, let's see if it comes back or not. the owner has had the car for three days, so far no errors....:hi:Quote:

I have reverted back to the stock tune didn't fix it, re wrote my map after finding it was missing parameters that the stock tune had. Still no luck also talked to the support line who told me to disable the fault code you get the same issue but without a fault code i feel it may be an issue with the software but need to talk with hp tuners support about the issue its a real pain in the ass as i need to bring a computer and my mates dongle with me when i drive and constantly reflash the car.
Is it possible to see your tune file vs stock file? I had a similar issue and just updated all aircharge conversion tables . I always had epc above 50% engine load . I believe the ecu sees not enough boost the same as too much boost. As weird as it sounds . It may be to prevent high turbine rpm from a boost leak . But idk 🤷🏼*♂️ just a thought .Quote:

The error already persist here after driving more 100-150 km, hptuners suport team they don't do anything. The problem is hptuners software?.. no tune cars with med 9.1 with hptuners
