Xineering Downshift Blip Module Overview
I think at least for me (Novice Vet driver) this will do the same for my driving.
I wonder if we could get enough people interested to get a group buy going? At $520. the price is actually quite good though.

The downshift blip module installs on manual cars and gives you automatic rev matching when you downshift. You can program how aggressive the blip is and a few other parameters that are in the provided instructions. You can also turn it on and off with a toggle switch they provide. I found this device useful because of the spacing between the brake and the gas. I never had issues heel-toe shifting my other cars but I did with the C6. With this module, I find I have a lot more fun with the car on backroads. I imagine the track will be where it really shines. Hearing the quick rev match when going through a tunnel, or anytime really, is frankly just a cool sound that adds to my enjoyment of the car.
It's turned on in this photo, the switch is lit up blue.
It's fairly easy to install. It is largely plug and play, but you need to tap into +12V power. They include everything you need to install it, including the positap to firmly connect to power.
I mounted the blip module under the passenger side of the dash and mounted the switch where the cigarette lighter goes. The programming wire feeds into my glove box.
Mounting the module:
I mounted the module by velcroing it to this metal box. It's on the far right side under the passenger side of the dash, you have to remove the panel with the footwell light to access it.
Mounted up closer.
Mounting the switch:
I bought a replacement cigarette lighter outlet which came with the tool to remove the stock outlet. Then I cut the back half of the outlet off so I could attach the button and feed wires to it.
Outlet cut and switch pressed in.
Switch pressed into the cigarette lighter outlet
Wiring. I removed the center dash piece to get to this point.
The switch snaps into place.
Xineering exchanged almost 40 emails with me starting with questions before I bought the module and even provided me with custom firmware to address some tweaks I wanted to make. Their customer service is top notch. Best I've worked with in a long time.
I can share my settings and answer any detailed questions, but that's the gist of it. I would very much recommend it now that I've got it tuned the way I like it. It just takes some trial and error.

I took inspiration from @C6_Prodigy with regard to the placement of the module and the on/off switch. I did a couple things differently, though. I mounted the module with the connector pointing toward the driver’s side of the car rather than down. I felt I needed a bit more slack in the cabling. My car has a telescopic steering wheel, so there are quite a few obstacles. See the pics below. It made routing the clutch/brake cable quite challenging. You can’t see much in the pic, but I’ll post it anyway. With the on/off switch, I found that with the lighter housing acting as a bushing in the plastic trim ring, the whole switch assembly would not snap into the console, so I removed the cut down lighter housing and put the switch directly into the plastic trim piece. It seems tight enough.
I routed the cabling the same - under the console, in front the area by the ashtray. I did not take pics of that because I was really focused on trying to finish up. It’s pretty self explanatory once you get it apart. The cables are also tucked under the carpet. I took power from an add a circuit fuse tap and for the ground, I used a Posi tap on the cigarette lighter ground wire.
I used the YouTube video from MGW Shifters to show me how to remove the console. The one part that was a PITA was that the factory used too much loctite on the shift **** bolt and it melted the plastic chrome ring for the shift boot to the shifter shaft. I had to peel down the boot and carefully use channel locks to get it to spin and the I had to reattach the boot with nylon ties.
I took it for a quick drive yesterday and it needs some tweaking for sure. I dialed the throttle setting back to 30% from the default 50% with no other changes, but I will definitely have to play with the settings more to dial it in. I hope to have a street setting and a track setting.
One big improvement needed on this unit is they need to put abrasion protection on the cables that go between the clutch and brake sensors. There is a lot of stuff under there that could wear through a wire. It took a long time to figure out how to get those routed so that doesn’t happen. I plan to email Xineering about that.
I still have to put the under dash panels back on. I was too wiped out to finish it on Friday.
Here’s some pics. Hopefully they help.

One other observation I forgot to mention - if I have it turned on and I’m sitting at a red light with my foot on the brake, if I then push in the clutch to put it in gear, it blips the throttle. It’s just something you have to get used to if you are playing on the street.
I found that I can't break the habit of accidentally triggering a blip when on the street so I turn it off and on quite frequently when I'm in the mood to use it. I even left it off at the track until I was at the starting line waiting to go.
