NOT TO PUT ANYONE DOWN...

Normally we use Flagship one for our computers, and for the last two times we had to get a GM computer, and BOTH times they messed us up by the instructions they sent us. We were trying for at least 3 hours to get it to work (2003 Chevy Impala), contacted them, NO HELP AT ALL! The person on chat kept insisting we had something wrong with the car, even though the old computer started the car fine (was not sending signal to turn fans on).

We came across this video, and BAM, car started up on the first attempt. They had us just turning the key to the "ON" position, where you have us turning it to the "START" position. Just wanted to let you know that we will be doing a video about your company, and from now on, you have our business, THANK YOU!

I tried your method and it worked. All the other videos miss the key detail of trying to start after each 10min and five sec cycle!! Awsome

This is the only video that works. Even the instructions I received from a seller on eBay didn't do the trick but this guy's video hooked me up.

I ordered an EMC from.u guys and followed your instructions..it worked VERY WELL.!!

[josephvasquez]

Great explanation for a vital component for such a complex process this guys expertise puts into a simple breaking it down equating formations easy like 123 or like abc 4 videos not enough enlighten us more intellectual than majority YouTubers explainers on the automotive material

Thank you! My car would not start with the instructions I was given where I bought my ECM. Watched your video and all is good. Thanks again!

[SimbaBeezFN]

Thanks a lot. I knew my ECM was shot when the Check Engine light was flashing up a storm and the stabiltrak warning came up. It was code U0100 when I scanned it. I just ordered my PCM last night. Hopefully I can get my Cadillac Wag back on the road soon. I miss my baby

[luisvalde]

U saved the day I got it started but I had to crank it the 1st time then not after 2nd and 3nd ty

[carlosvangrinder]

Thanks for posting this, it is probably helping a lot of people. Thought i would add my experience to the comments though as it didn't work for me. Apparently if the TDM is configured for export the 30 minute process will not work for you. If the car is made in the USA and exported then it doesn't work and you will have to program it with a scan tool.

my battery almost died on the 3rd attempt... so i got out the charger.. I had to do it 3 more times. It works!!
