I received my Racechip GTS Black today and its very very pretty. They spent a lot on marketing, BUT the installation instructions are pure crap. I just sent their support group a message regarding better instructions.

The module comes with a 3 sensor harness:

(A) - Turbo Boost Pressure Sensor
(B) - Manifold absolute pressure Sensor
(C) - Camshaft Sensor

Can any of you please tell me the locations of those sensors?

When I purchased my RaceChip Ultimate, the seller (since, seemingly taken over) sent me a nice set of pictures showing the connections. I've attached a PDF of these along with an explanation of my understanding of "what's what" regarding the sensors/connectors. Assuming RaceChip is still labelling the sensor-connections the same, the attached PDF should do it.

Question: Does the GTS Black only have 3 connections?

OC43AMG

Thanks, Its strange that the camshaft sensor is different then what BMS showed me for the JB1 (which is on the right side of the engine bay).

Yes the GTS black only has 3 sensor connections.

I got the wiring installed according to the PDF that User33 sent me. Where did you mount the actual control unit? I cant seem to find a good place for it. I love how well made the whole unit looks.

Yes I got the mobile app! its awesome. I am waiting for tomorrow to test it out on my long commute to work.

The Cam Sensor is in different a spot according to Racechip

Perhaps they are different. But the purpose of me linking you was to show you where I secured the harness.

I'd guess there are at least 2 cam sensors, 1 left and 1 right (likely 2 each, intake and exhaust?) ... can anyone with EPC/WIS access confirm?

Also note that the info on what the A, B & C sesors are was added based only upon my understanding (and I don't have EPC/WIS access). OTOH, sounds like your install is working, as ID'd by the butt-dyno.

CFG, can you send me a photo of your mounting location? I had it mounted on the driverside oil line but it seems like it gets too hot there. Now i am looking to place it on the passenger side near the battery but there is not much clearance.

CFG, appreciate that very much. Thanks! I mounted it in the same spot.

What happened with the JB1? Do you feel a big difference with the GTS compared to the JB1?

OC43AMG

I am giving it some more time. So far it feels identical to the JB1, maybe even giving the JB1 a slight edge. I think the JB1 might have increase boost a little more down low, but im going to give it another 200 miles to get a feel of it. I do miss all of the data that the JB1 logs. GTS black is like a piggyback for dummies, where the JB1 give you a lot more control (but the JB1 hardware looks unfinished compared to the GTS Black.)

Another great feature is the bypass plug, which you can pop off the control unit very easily, although im sure any mechanic would notice the aftermarket harness.
Overall, i would probably keep the Racechip in the car. It has great features like the warm up timer and i like the fact that it is more of a finished product. I will keep the JB1 just incase BMS decides to tweak the tune and add JB4 capabilities.

In short, the JB1 is a fking BARGAIN. They changed the case to make it feel less like a POS so it costs $100 more than before but it is still a bargain even with the more expensive price.

The old casing and finish looks like something similar to a 1990s TV remote from Sears.

The new casing and finish looks like a 1995 tape recorder from Radio Shack (not even Circuit City). But it is an improvement I guess.
And I am sure its part of the reason the unit is so competitively priced (plus the fact that it does not come with built-in bluetooth, that is extra).
