Ordered a RaceIQ Tune via @Anthony Lawshee &Co, for the C55.
Anyone running it? Any advice? Thoughts?

Thanks in advance!

I'll update everyone on how it goes.

The cable arrived in the mail.
No tune file included.
Sent in the details as requested on the instructions printed with the cable ---, (that I had already sent in when I placed the order)
Drivers and software are installed. I pulled the ECU info and proactively sent it in.
Waiting for a response.

We'll see what happens.

Got the tune will be applying it soon.

Tuned in for your impressions. Don't see anything on their website for the C55. Only C32 and C63. How much are they charging for the C55 tune?

Anthony was responsive - the process fried my stepper motor. There's no doubt about it -
My ESP threw an alert and car went into limp home mode on the first drive attempt.

Reapplied. it does seem faster and smoother. Not sure if the process was worth frying the stepping motor over. Just be aware the ECU tune will unleash electrical gremlins if you've got them. Not the best experience, not the worst.

After half a year or so, are you still happy with the tune? Also, to clarify, the process of loading your engine tune caused your HVAC stepper motor to fry?

I also have RaceIQ tune, full dyno when uploaded, been a month+ on the tune with lots of driving and everything has performed flawlessly. Noticeable torque increase throughout the powerband. The critical things to do when uploading the tune are to have the battery on a charger or something to guarantee voltage staying put AND unplugging cooling fan. Anthony is a great dude with years of experience in the game.

I am curious to know the OP's definitive answer on how the tune was linked to HVAC motor failure? Not doubting the possibility, just seems very bizarre.

kaixdiego....

Can you make any comparison of raceiq versus eurocharged?

I wanted to clarify it was the HVAC he was talking about because it isn't clear to me how a fried HVAC stepper motor would cause his car to go into limp mode and throw an ESP alert. I'm not certain at all that HVAC is what he was talking about. I actually assumed he might be talking about the motor in the throttle body, but after viewing your video where it states to unplug the fan, I wanted to clarify what he was talking about when referring to the stepper motor. Doesn't make much sense.

Rob - I don't have any direct experience with Eurocharged and don't plan to change tune, so unfortunately don't see a comparison taking place atp...

Brauhaus - I see! I misread, I would assume now also that the stepper motor would be related to throttle body but I guess we are in the dark until op responds. Interested to hear exactly what happened.

brauhaus313

Was it RaceIQ that instructed you to unplug the fan?

kaixdiego

Yep, Tony said those two things are critical to make sure things go smoothly.

I'm dyno tuned by Vtech and I would recommend them. Never had any issues with install; uploading was a breeze. I was able to beat an RS3 (~15mph roll) with only long tubes, tune, TCU, and intake.
