Racechip GTS black
Just put a Racechip GTS black piggy back on my C450. It replaces a Dinan Sport. All I can say is wow, this one you can feel and the app is only Part crap. I have no idea what the engine makes, but I can tell you that subjectively it is a whole new level of performance.

Its ridiculous. You either measure it at the wheels or vs factory crank.

racechip claims 434 HP, somewhere! All I can say is that subjectively, the car feels great. The Dinan Sport did very little.

OK. Thanks for making this thread. I took one for the team and beta tested the Dinan Sport. I was thinking of going JB1, but I may add Racechip to the short list. Please let me know if it holds up well or if it ***** the bed.

I'm having big problems with my Dinan Elite, they need to send me a replacement unit. If I don't have luck with this one, I'm going to be going with the racechip after demanding a refund for the Dinan.

Hi, I am wondering how to change the drive mode if you didn’t get the mobile app that costs $50? Can you still use the same up down button to change it? If yes, how do they correspond to the modes as stock has 4 modes and RaceChip has 3 modes? Thanks

This sounds like a great product and thank you for posting, I just wish tuners would be more forthright with actual hp/tq numbers over stock increase.

I think most piggybacks will give you about the same gains, not saying the same total horse power since the same cars with the same engine will have different Max HP. You can even take the same car to different geographical locations and have different HP from one location to another.

my car with a BMS piggyback will do same 0-60 as what the RaceChips one did at a discount

For comparison, my best with BMS piggyback.
With map6 " Your 0 to 60 time is: 3.34 "
With map2 " Your 0 to 60 time is: 3.56 "
With map1 " Your 0 to 60 time is: 3.71 " <<< this is the 91 octane map with 93 in tank.

Correct, most piggybacks should be the same, it's not rocket science. They just raise the boost 3-5psi and let the ECU compensate for the rest (fueling and timing). Similarly to canned tunes sold by major vendors on this forum, they all all about the same. The only difference is the canned tuned fueling and timing are already maped where the ECU won't have to do much compensation, it still does, but not as much as piggybacks.
For comparison, my best with BMS piggyback.
With map6 " Your 0 to 60 time is: 3.34 "
With map2 " Your 0 to 60 time is: 3.56 "
With map1 " Your 0 to 60 time is: 3.71 " <<< this is the 91 octane map with 93 in tank.

that 3.34 to 60mph is in super car territory- very impressive!

Below are Map2 settings
>> 'RPM based target
>>>>>>>>>>>>PSI >RPM
>> psi_curve[0] = 3.0 '1500
>> psi_curve[1] = 4.0 '2000
>> psi_curve[2] = 5.0 '2500
>> psi_curve[3] = 5.0 '3000
>> psi_curve[4] = 5.0 '3500
>> psi_curve[5] = 5.0 '4000
>> psi_curve[6] = 4.5 '4500
>> psi_curve[7] = 3.5 '5000
>> psi_curve[8] = 3.0 '5500
>> psi_curve[9] = 2.5 '6000
>> psi_curve[10] = 2.0 '6500
>> psi_curve[11] = 2.0 '7000
If you request (3.5-4psi) in Map6, you will have a custom "Map6" that's between maps1 and 2, you can call it Map6 or Map1.5
If you request (1-2psi), you will have a very mild tune that is still "Map6"
If you enter (20psi) over stock, it will accept your input, but it won't give you 20, it has a built-in safety.
The advantage to Map6 is, you can slightly increase or lower boost over maps 1 or 2 in certain RPM to accommodate you driving style, launch, flooring it on the HWY, etc..
BTW, the 3.34 to 60mph was on a well prepped track with 30% e85 mix in the tank.

Map6 does not come with any settings, you have to input your requested boost (above stock). Map1 comes with (2-3psi) over stock and Map2 (2-5psi) over stock

I wonder how does the gts chip influence the reliability of the engine? I have 100K kms on my used c450 (mostly driven in Russia/Belarus where gas quality might not be the best and you never know if it was abused by previous owners) and a bit paranoid that I might run into some issues as mileage grows

Fuel Octane Effects?
Does anyone know if the GTS Black on our C450/C43 make any difference with E85/E30 in race mode?
Also, maybe for a different forum but I'll ask incase anyone here is knowledgeable. Is there a way to remove limiter without voiding warranty?
