Mk7 Speedometer Correction

I know I normally publish on Tuesdays and Thursdays but this is fresh in my head so here we go!

Since putting on the Nokian Rotiivas, my speedometer has been off about 8% from my actual speed due to them being larger than OEM. This may seem like a no brainer to just go slower. True, that is an option but not something I want to calculate while driving. I found some useful information today and put it to the test and was pleasantly surprised with the results. Simply, you have to change the coding of the Instruments and I did this with VCDS. Before I get to the coding, you need to understand the sizing and impulses being read.

When the wheels spin, the ABS sensors measure the rotations and send an impulse to the computer via witchcraft/magic. The computer is programmed to take those impulses and convert them to the speedometer with a set formula that is set with coding.

The 215/65R16 tires that I am running break down to this: a diameter of 27" (685.8 mm) and a circumference of 84.84" (2,154.936 mm). There are 43 impulses per revolution and the math I found in order to figure out the revolutions per kilometer, is 1,000,000/circumference (in millimeters). So with this tire, there are 464.05 revolutions per kilometer and 19,954.15 impulses per kilometer. With all of that known, this chart I found was very helpful:

The file was a read only document so I couldn't change the numbers up top but the formulas were there and the important information is on the bottom. Of the numbers shown the one column closest to my numbers were column 4, and when I coded the car to that, my speedometer was where it needed to be. Now to the coding; it is simple.

Using VCDS, access the Instruments group 17.

Select Coding and then Long Coding Helper. Once in, toggle over to Byte 3 (the fourth little box with numbers in it). You should see the screen above. The drop down menu from the factory should have 05 Tire Circumference: Variant 6 selected. Click on the drop down menu and select 03 Tire Circumference: Variant 4.

Close the window and select the Do It! button. That's it!

Please, take notice of your stock settings so that if it doesn't work you can revert back. This worked for me and I am really happy to have a normal speedometer/actual speed.

Bearded Elevation System

This post has been a long time coming and I am so happy to be typing this out and I am not even close to being done!

Since buying our Alltrack back in July, I have seen many inquiries about lift kits. Almost every day I was seeing a new post about it. I originally reached out to a company that does lifts for Subarus and I had also done a poll on two different Facebook groups to see what the legitimate interest would be if a kit were to be produced. After the company took a long time to respond, I decided to undertake the task myself. There was a huge learning curve for me since I had not used AutoCAD since high school (almost 15 years ago), nor did I have access to any of the resources needed to 3D print or produce a prototype.

I will fast forward through all of the trial and error bits but I did finally settle on a design that I thought was unique enough that I wanted to protect my intellectual property. I filed for a provisional patent for my front lift kit spacer and before I go further, I guess I should explain why.

The Mk7 Golf is on Volkswagen's MQB platform and like other platforms in the past, it has a MacPherson front strut and a multilink independent rear shock and spring. The concept of lifting a car with this setup is simple: a spacer in between the front strut assembly and the body and the rear spring and the body. The front has a rubber strut mount that is bolted to the body and my concern was, and still is, using a single piece spacer with longer bolts to achieve the lift. This is where my idea for a two piece spacer came into play and that is what I filed a patent for. This will use OEM strength and length bolts and therefore not be more prone to failure from torque.

Recently, I got the lift kit on the car and I first installed a 1/2" lift and then a 1" lift. These will be the two sizes that I will be offering through The Bearded Detailer so I wanted to be sure to install both.

After a week of driving on the kit, I went ahead and ordered the all terrain tires I decided on and dropped off the 16" steel wheels I acquired for powder coating.

I decided on the Nokian Rotiiva AT in a 215/65R16. The reviews were really good and they have a pretty good wear rating. I won't lie to myself or anyone about the amount of highway driving I do and that won't change with this setup so I needed to be able to have a tire that could hold up to that. The steel wheels got finished in a metallic silver very close to the OEM silver alloys and their specs are 16" x 6.5", et50. I also picked up OEM wheel caps (5N0-601-169-X-RW) that I believe reference to a Canadian Tiguan setup. I could be wrong on that but I have had them before and if I am going to run steel wheels, that is the only way for me to go.

Installation day finally came and before the tires were mounted, I coated the wheels with Opti-Coat Pro to make sure they stay as clean as possible when I do end up off road. The dealership was able to balance them with stick on weights since their finish was now similar to alloys. I stuck around and had my friend Connor align the car since the alignment hadn't been touched since the lift kit was installed. I will have more information on the alignment when the kit is finally available to the public but I am content with the specs.

I drove out to get photos that evening and I am so happy with how it all has come together. I will be spacing out the rear wheels 15mm as well. I am content with where the front wheels sit.

Also took the car to a small local show on a whim and the car and kit got some interest. Overall, the car now sits about 1.5" taller than a stock Alltrack and while the tires aren't meant for performance cornering, I am happy with the ride of the car. I do recommend an upgraded rear sway bar and some form of engine tune for a few more ponies due to the added unsprung weight.

Behind The Scenes!

First and foremost: I want to thank everyone that has shared and supported the release of the kit. This can only be a success if more people know about it.

I will get to the alignment. I can't force anyone to get an alignment but do yourself and your tires a favor and get an alignment. You should be doing an alignment once a year at minimum as it is.

 So this is a printout of my alignment and I will state that the BEFORE is not before the lift kit. That is with the lift kit as I drove it to the dealership and the AFTER is how I drove it home and how it currently sits. I never had the car aligned prior to the lift kit but based on printouts of others with stock Alltracks, I can say that the 1" kit added about .4º camber in the front and .13º in the rear. The factory specs call for -.27º ± .50º camber in the front and -1.33º ± .50º camber in the rear.

The front is what should be focused on since it isn't adjustable and the rear is. He was able to get the caster and toe as close to factory as possible and then he adjusted the rear camber about a half a degree to match the front movement. I think my next alignment, I will make the rear match the front closer.

My overall thoughts on the performance of the car? I love it. One thing you have to remember is that the center of gravity has been raised 1" so the will be a slight difference in cornering. This is also true of tires with larger sidewalls. But after a few days of driving, you will get used to the feeling and realize that it is not unsafe. I do about 18,000 miles of driving a year and many family trips with my kids and dog. The last thing I want is an accident with them in the vehicle with me.

Over the Memorial Day weekend, we took a trip up to my parents' house in Bradford County (about 300 miles round trip) and made sure to hit some rural routes that I grew up driving on and leaving the beaten path. The car performed exactly the way I wanted it to.

And that about wraps this up for now. The group buy is still active on Facebook and on the Swag Store until the 21st of June. Again, I thank you all for the support and I look forward to getting these out into the hands of many Alltrack owners!

Cadillac Eldorado

This isn't a car you see every day, let alone detail! Paul wanted this 1975 Eldorado shined up so that he could sell it and a Full Detail and Engine Bay Detail did just that. The condition wasn't bad at all but still needed a polish to bring it back to near perfect. The car was finished with Optimum Car Wax and Opti-Coat Hyper Seal. If you are interested in purchasing this car, please contact me and I will put you in touch with the owner.
