I'm using (without much success so far) Torque Pro to assess the effect of some piggy-back "tuning" solutions on my practically new BMW 528xi vehicle.
Recently when I was trying to measure my 0-100 kmh time, after flooring the gas pedal my engine just died for a while (no power, revs down, "Drivetrain Malfunction - power limited" error display). I panicked, but after re-starting the engine all is back to normal. However this happened to me for the very first time, and with the ELM dongle and Torque Pro active - could they be the reason? I mean - does Torque Pro "talk" to the ECU through ODB-II, or just "listen" to it; if the latter it couldn't possible have caused any engine malfunction, or could it?
Anyway - please tell me authoritatively whether your Torque Pro application is able to clear all hidden error codes (including the new 29.2 and later ECU software and MSD81 ECU designed to detect tuners). I wouldn't like to have my warranty voided....
Thank you.

Isn't my problem serious enough to deserve an answer, please?
This is my 3rd attempt to obtain some help from the Torque Pro supplier; here is an update:
I removed my current Speed-buster box and went in to my BMW service in order to check the memory of my ECU, hoping it would give me a hint on the reason for the “Drivetrain Malfunction…” error. Because it’s scary to drive a car which can cut the power almost to zero, just when you need most of it to safely complete bypassing, or any other road maneuver. I was very curious whether or not the 2 occurrences of the said engine ‘crash’ have in any way been related to using the Speed-buster tune…
Well, the output is following:
At the very time it happened to me lately, the following errors were recorded:
Code: 120308
Description: Charge-air pressure control, plausibility Pressure too low
(this is when the “Drivetrain malfunction appreared, and the power was reduced to zero)
- Followed shortly by a couple of what BMW says related errors:
Code: 108A01
Description: Charge-air temperature sensor, electric: short to B+
Code: 108A10
Description: Charge-air temperature sensor, voltage change: too fast
My BMW service is going to replace the charge-air sensor. But, they are unable (or unwilling) to further comment on the nature of the above error codes (they set up a PUMA case). Is any knowledgeable soul here able to comment? Any comments welcome - I'd love to trust that by the sensor replacement, I can get rid of the fear my engine will cut the power almost to zero, just when I need most of it to safely complete bypassing, or any other road maneuver !!!
My 2 most important questions are:
1. Could the above faults be related to the piggy-back tune?
2. Why weren't they cleared by Torque Pro?
3. Where can I find any description of the above fault codes (5-character codes are new, aren't they - my car is a 2013 BMW 528xi)
Thanks and Regards
This is my 4th attempt to get any feedback from the Torque Pro support. I have already had to accept there are no Help pages for this application, but not having any off my questions answered in this forum makes this app useless to me 🙁
To the authors of what used to be a wonderful application (so people say): please give us more support!
Hi - sorry for the delay in replying - there's a lot happening and I'm investing a lot in the app at the moment which is causing delays replying to some things
Some ELM327 adapters can cause this (only the clones if you get one that has been very shoddily tested) so if it's this you should replace the adapter, though it's not always easy to tell with very intermittent faults. (usually if it happesn without the adapter connected, that you can rule it out)
I can't comment about the tune, as I don't know how it's coded/works/connected so can't provide any insight into this. Bear in mind that some tunes do push the engine harder though (more than the default manufacturer settings). It is certainly possible for a tune to cause issues though that would normally not be triggered/happen/etc.
The fault codes you've quoted aren't OBD2 fault codes - they're native BMW diagnostics codes (an entirely different system). OBD2 primarily covers powertrain and emissions sensors (other bits at the manufacturers discretion, and nearly always ABS isn't part of that inclusion)
