OK I purchased the SPS2 software for 2 VIN, GDS2 (not needed for this) and MDI2. A technician at Bomini Chevrolet walked me through the process (AWESOME GUY!).

Webpage with the software:
ACDelco TDS

VERY IMPORTANT! MAKE SURE you either a backup car battery at the very least, or at best a power supply designed to maintain exact voltage such as Midtronics MSP-070. Do not use a common battery charger!

Also, use the PERMANENT ACCESSORY ON by holding the start button WITHOUT pressing the brakes until all systems are on, and THEN releasing it!

First, you log on to the ACDelco techline connect website. Buy SPS2 for one vin ($40!). Then choose vehicle programming software (view) and add VIN (unless you have already used SPS2 before). This brings you to a tech connect install/load page. Download and install the Techline Connect software from this page.
Run the MDI2 program and make sure your MDI2 is up to date
Then go back to the website, Choose vehichle programing software (view), add vin, then click launch Techline Connect. This will load Tech Connect and update/install (ONLY WORKS ON WINDOWS 10! Windows 11 will NOT properly load the program due to spaces in the filenames!)

Once all of the updates/installs are done, restart, go back to the SPS2 page and click the launch teachline connect once again. Now your SPS program should launch. Connect your MDI2 to the car and the computer, wait for everything to update/initialize. Connect to the car via the button at the top, choose MDI2. somewhere in this area, the program alerts you that you will be using one of your VIN slots for SPS2. You then be led through a series of pages, answer the questions and remember you are wanting to PROGRAM the NORMAL (not VCI) Engine Control Module K20. you proceed through the pages by clicking the green NEXT button in the bottom right of the screen. I can't remember the exact pages, but it was not that complicated. It will download the tune from GM TIS2WEB automatically once chosen, you WILL need internet on your laptop that you are using for this! Once you program the ECM it will return to the same page. You will know you are using the correct program as it will ACTUALLY mention PROGRAM to FIX P0106 as one of the line items! Also, you can clear the DTCs after you reprogram by pressing a button on the bottom right.



Feel free to sticky this, use it on the site, or whatever I will be updating it with more precise instructions when i do my 2018 z06 next week!

ask questions, and I will fill in what I missed.

 

Ive used the SPS2 page with a VCM Nano with good luck too. With that said, I would 100% only ever program the car with a power supply attached to the vehicle, specifically one that is meant to hold voltage stable during programming. Voltage issues can and will cause programming failures, which likely will result in module replacement needs. Other than that, very easy to do as described!

 

Actually, it says a secondary battery NOT a charger. Absolutely do not use any device plugged into AC power while programming.

 

Any charger plugged into a UPS would be just fine. With a slight risk you could also use any device plugged into a transient suppressor power strip, the risk being the AC power drops out and you don't have enough car battery to cover the drop out time..

 

I didn't say a battery charger, I said a power supply. And absolutely 100% yes, you should use one (plugged into to AC.)

Battery chargers put out a specific amperage and cycle on and off which creates voltage fluctuations. You do NOT want this programming, but again this isn't what I suggested.

Power supplies are specifically made for programming. The hold voltage constant and vary amperage depending on the current required. All manufactures require them when programming. Hooking up a second battery is a bandaid at best

Step one of any manufacturers programming instructions is always going to be hookup a power supply.....


EL-49642 is a Power supply.... https://www.vehicleservicepros.com/s...amming-support

 

If you read the CURRENT TSB for P0106 it specifically states to plug the vehicle into a special AC Delco programing support tool with a specific part number and if that is not available, use a booster pack and INSURE it is NOT plugged into AC. The TSB that’s floating around on this forum has been updated and includes 2018 cars. It is on GMs website.

 

So now you're agreeing with me? LOL.

Translation of what you just said: The TSB says to plug the car into a programming support tool (which is a power supply). Power supplies don't work magically and grab power from mid air, they need plugged into the wall to function. As I said in post one, they vary amps to keep voltage rock steady and clean which is vital to programming. If the best option (power supply) isnt available, then you can use a booster pack as another less preferred option. Also dont have the booster pack plugged into the wall and charging while using this method. My addition: However, if a programming session takes longer than expected, which does happen, your risk of failure due to voltage drop expands drastically with just a booster pack hooked up. You've been warned.

Look, not trying to be difficult but my entire life has been spent in the automotive world. From hobby, to schooling, to professional career. I love the fact you went out there and programmed your car. That's awesome and I appreciate you sharing your experience. What's not awesome is spreading wrong and factually incorrect info and passing it off as expertise, when your sample size is one and blatantly contradicts what every manufacturer in the world suggests, GM included.

The professional and "right" way to program any modern car is with a programming power supply attached (and plugged into the wall LOL). End of discussion as there's nothing to argue here. No more responses from me. Ill let any future readers figure out what they want to believe.

 

I will admit I did not know what the “support tool” was. If it’s a plug in device, it is what it is. I was thinking it was a battery pack. I will be ordering one.

Thanks for the information. When you said “power supply”, it sounded like you were talking about a charger which it specifically says not to use. In any case I misunderstood that the power supply and support tool were one in the same.

 

My 2018 z06 threw the P0106 code today at homestead in the same damn spot as the wife’s! Here we go again. I will get a support tool/power supply before I update this one. The wife’s car threw a frigging service axle alert and slammed the brakes on mid corner! Wtf with these Chevys!?!?

I have 2 C7 Z06/Z07 and 2 2020 GT500s. The GT500s have been to 5 track days at homestead/Miami (in the summer!). One at gateway. One at heartland. One at Ozark International. NOT ONE SINGLE CODE! Not one single problem.

I have had my 2018 Z07 at homestead for 3 days this winter. I’ve overheated twice, thrown P0106. Wife’s Z07 car has done 4 days at homestead. One day at gateway, one at heartland and one at ozark. Thrown P0106, overheated once, service axle, slammed on brakes mid corner. Just crazy!

 

Beautiful paint on all of those cars.

Thank you for sharing the information and the link to AC Delco Tech Delivery system site.
I had no idea AC Delco provided this service and it was relatively affordable.

Good info.

Thanks

 

Nice write-up

 

I've got a midtronics MSP-070 on the way Thanks!

 

Its a good investment if you're going to continue to work on your own vehicles!

 

I have updated the original post. The support tool is awesome! I reprogrammed both cars with the K20 and K47 updates. The wife’s car had a service rear axle alert last weekend which slammed the brakes on mid corner! Hopefully this fixes it.

 

Well..... After updating K20 and K47 in BOTH cars we had a track weekend without ANY issues, YAY! I HIGHLY recommend having your dealer do BOTH updates to 2017-2018 Z06 vettes.
