Evening #1
I received some generic VW instructions form RaceChip, then they emailed me supplement with a few photos of a jaguar. These are the same photos posted elsewhere in these forums. Pretty straight forward as to how it connects, redirecting MAP and MAPT. Took my time as I didn’t want to face any broken parts or undoing mistakes. The MAP took a minute and I thought I would be finished in a matter of minutes. Yeah right...

The MAPT/boost sensor connector at the back of the engine was a real challenge. My 2016 model had more of a cover over the back of the engine compartment than the photos showed, and there was very little room to put a hand. The connector is at an angle and is in a hard to access position. After one evening of barked knuckles I asked the forum if they had any tricks, who mostly confirmed that it was a difficult place to get to. Owners suggested a remap on the ECU (expensive) or possibly trying to wire a connection closer to the ECU (a bit scary for me). I decided instead to have a beer and sleep on it, pondering the prospect of having to return the RaceChip if I couldn't solve the problem.

Evening #2. I decided that a lack of technology was my problem, so drove down to the local tool shop and procured some new tools for working in hard to reach places, plus an illuminated mirror.



Used gently, the hose puller tool (on the right) was good for releasing the lock and unplugging the MAPT connector. I secured the loose connector with a ziptie so it didn’t fall into the depths. (2 hrs including the trip to the store). Considering this good progress I went to bed.

The next morning I decided to take a run at it before going to work. Plugging it all back in actually proved more difficult for me because I had to match the angle of the plug receiver without seeing it.

I tried the mirror which took a bit of effort to position because of the lack of space but after I found the right angle I ziptied the mirror into place to free up both hands. The mirror wasn’t very useful once I was close in, but it helped to set the plug at the right initial angle as a starting point. I positioned the new plug using the 90° pliers and then switched hands hands to nudge it into place with a finger. Using one had over and one finger under I was eventually able to plug it in. (I did not remove or disconnect anything else on the back of the engine to get more space.) (2 hours)

Once turned on the RaceChip threw no errors but the device didn’t connect immediately through Bluetooth to the app on the phone (Android). In retrospect it seems to be sensitive to the software sequence, so I got success after uninstalling everything and reloading in the exact sequence in the instructions, which included loading the ap then pairing. The single clarification call to tech support went quickly and worked. They seem to be very responsive and helpful. All ended well. (45min)

Much to my relief the car started fine and I didn't have to troubleshoot anything.

Results:

The first run in default setting 4 (sport) seemed to feel a little gutsier, but a time/speed run was about the same as stock (21.7s@123MPH). I did not have time before leaving town to test it further, so I am looking at more testing in settings 5 and 6 (I have the RS version of the RaceChip) next week, as well as looking at the fuel economy. But so far so good as far as nothing unexpected so far. The installation did not seem to disagree with the car and we had no hiccups, pops, tapping, knocking or unexpected farts. The car runs at least as good as it did before at first glance.

Lessons Learned:

RaceChip installation on the XF for an inexperienced person like me takes a little time and patience, and in my case about $50 in additional tools. (The compound pliers I never used except for retrieving my dropped 90° pliers) (;>

I was interested in the RaceChip with the hopes that I could take it on and off as needed to have warranty work done at the dealer. If I decide that I want to keep it around, I think that I will try to build/find a 2” extender plug and wire so that I can plug and unplug the MAPT without having to reach into the back of the engine to do it. It is too difficult to connect and disconnect even with practice, and I don’t like doing things by feel. The dream of quick connect and disconnect is waning a little unless I figure out the plug extension.

I am overall encouraged and will post more next week when I have a had more time with it.

To an early question about what the different maps are intended to do (from RaceChip):

"...Yes, each level on the RaceChip is a more aggressive tune.
-Map 0 will be the car back in stock condition. Perfect for valet's, someone borrowing your car, or even going in for service.
-Map 1 and 2 will be the economy modes. Perfect for a road trip and maximizing fuel economy.
-Map 3 and 4 will be our sport modes. A nice balance of power and torque over stock with smooth acceleration.
-Map 5 and 6 are the Race modes. Take your car to the next level with a significant increase to power and torque."

My question is, is the hard to reach MAPT sensor located in roughly the same place on the XF as the XJ? Id like to mentally prepare myself if it's going to take me hours to find and attach.
Any advice is appreciated
Thank You
