Why not program it through the OBD?

Everyone should carry one on the truck to quickly swap on for troubleshooting the ESL.

Not to mention liability. I personally do not do them because I like working on stuff where I am more able to control the outcome.
When they hit an oak tree a week after they get the car out of the shop, the airbag fails to deploy, and they do a faceplant into the steering wheel, they are likely to not be understanding.
Of course everything we do carries liability, but that is just not one I prefer to take on.

The customer's computer had water intrusion.
This is an easy swap via eeprom, using a used donor ECU.
I changed the eeprom and the 28 legger I am pointing to, as well as the the 14 leg device straight across that forms a triangle with the other 2.
I really do not think swapping the 28 leg device was necessary. Next time I will forgo it and see if I get the same results.
There is a caveat with this board that some of you are probably aware of. I just discovered it today. The components were glued down to hold them in place, before they were soldered. The glue that holds them is pretty firm. You have to liquefy all of your solder before you pry the the device off the board. The glue holds so tight that you can easily lose the device when it let's go. After the first one, I did the rest down inside a drawer in my bench.
You will have to scrape the glue off the devices and off the board in order to get them to lay back down properly for resoldering.
The glue is not solid, it is in spots. It scrapes off easily once you get the spots exposed.

Can you post a picture of the label on the computer?

Thanks Yasser, still mulling this over.

Yasser,
Are you using this mostly to virginize or rewrite used modules or new ones? Will it do both?

This particular car was a later model car that does not utilize a VATS module, but stores the information in the BCM. The BCM was bad in the car. As soon as you turned the key on, the security light as well as other dash light would start blinking, as well as one of the needles on either the tach or speedometer. (I don't remember which) Also, I could hear a clicking under the dash that was in rhythm with the cluster blinking. I traced it to the BCM, and a relay on the board. Incidentally, this cycling relay coincided with a no run/no start condition.
I ended up advising the customer to get a new BCM from Oh'Really. When the new BCM was plugged, everything seemed normal except the security light flashing. I could not get the Tech2 to program the BCM. I did use the Tech2 to do a theft system relearn, and as soon as it went through the 10 minute wait, the security light went out, I cycled the ignition, and she fired up. The BCM still would not program with tech2. It kept giving a no communication message.
Put the 608 on it and noted that the unit was actually a refurb. It still contained the VIN from the donor vehicle. Surprisingly, the 608 allowed me to edit the VIN in the BCM. Then it showed success programming the BCM.
When I finished the interior lights and the automatic windows did not work. I had the following 2 codes. I referred the customer to an auto electrician, and advised them that it is possible that one of the 2 diagnostic codes could have been responsible for frying the original module.

I swapped all the devices on the board to the donor module. I screwed something up, probably on the big microprocessor.
The car started and motor ran smooth. The car would not shift into gear, and the windows would not work.
I had the customer order a new BCM, and I will try to flash it with Tech2. When you are programming these BCMs where the VATS system runs through the BCM instead of a VATS module, does it recognize the first VATS value it sees?
-
I forgot the picture.

This customer had a problem with his vehicle. He thought it was the VATS ignition, so he replaced it and called me to cut him 2 keys off the dummy blanks with the correct VATS value.
I get there and realize his problem is not VATS related, but is indeed the BCM. As soon as I turned the ignition on, I hear a clicking sound under the dash? And every time it clicks the security light, as well as other lights blink, and even one of the needles in the cluster jumps repeatedly.
I traced the sound to the BCM, and upon cracking the case, I could see that it was a relay soldered to the board that was malfunctioning. As soon as I unplugged one of the plugs going to the BCM, the relay quit cycling, and the security light would go out when ignition was turned in with a proper VATS value.
I figured it would be an easy fix to have him get a used BCM, and I could rob a relay off of it, and swap it onto the board of his BCM.
I can't get that sucker to give it up. I am not sure what is holding it to the board. Hot air on the opposite side if the board is not giving it up.
I know if no way to program a used BCM to a VATS vehicle, so I would like to try and swap the devices necessary. I am sure the large microprocessor has to go, but I am not sure if any of the other devices need to swap.
Anybody have any input on what needs to be swapped?

When this car did start the mechanic said it would crank start then die.
That is a classic symptom of a bad BCM. It manifests itself in the same way on a Passlock 1 and Passlock 2 vehicle.

The dealer will tell them that the only solution is to replace the computer, to the tune of about 15 bills.
At least that is the M.O. of the dealers here

No starter when it doesn’t work. It’s intermitten.
You still didn't answer the question about the security light. Does it stay on when you get a no crank?
If it does, the easiest way to test if it is is wiring ignition problem, is to read the resistance on your current key with a multi meter, then solder in a register with the correct resistance for the vats value, as low in the chain as you can. If the problem persist, you know it is probably a problem with the vats box, or the BCM. Some of the later model VATS vehicles don't have a VATS module, but it is controlled by the BCM. It could also be that the signal from the VATS box or BCM is not getting through to the computer.

...if they sourced the correct computer.

I hope you don't believe me to be difficult Yaser. I am really very seriously interested, and would not mind dropping the money immediately if I felt like it would be profitable for me.
-
Also, what is the arrangement for Tech Support. Will you be providing Tech support Yaser, or will their be another source?

If you purchase the Master version. You are set. There is a yearly update fee if you decide to purchase it.
This tool is best for those members (teksavvy and heavily involved with eeprom work) that work with mechanic shops who replace transmission and engine modules. The ROI is high and competition is low. Diversification option for those that are looking to dive more into this world. The nice thing about this line of business is failing ECUs are common and expect repetitive business once the shops (or general public) know you can handle them.
How much is the yearly maintenance fee. I am pretty heavy into eeprom, but it doesn't seem that there is a lot of difficult eeprom from your demo.
I already do a lot of simpler computer swaps for shops, writing VINs, matching modules etc. I would just personally need to know what I can do with it. I have no way of knowing what on the list is for U.S. market or if 95% of it is for Europe, Asia or China market.
I have no doubt that it would be a wide open market. I just wouldn't want to drop 7 Large and find out I can only do half the vehicles I want to do. I would mostly be interested in doing VAG, Mercedes and BMW.

Master Full Flex $7k USD regular
$6800 for keypro members.
Also note once you establish a good market for this new line of business, you can always upgrade from slave to master.
That would never be an option for me Yaser. I just can't ve at tge mercy of someone else getting a file back to me. If I were working in a shop, that would probably work, but not as a mobile service. Every minute I am waiting, I am losing money.

If I could be indulged for a moment, I would like to talk about how to market to idiots...
That is a pretty impressive list. However it is something that is not useful to me in order to make a determination if the tool is something that I feel I could make money with.
I would need to know which vehicles are in my market. Also, the part numbers for ECUs does not say a lot to me. I need to know which ECUs for which models are covered in my market, and which are not for the same vehicle.
That is something that I could spend hours upon hours researching, but it quickly becomes something that is not worth it to me.
I don't mind dropping $7G on a programmer, but I really need to know if there is going to be a market for it so I can get a return on investment. If I have to spend days researching to find out what cars in the U.S. market that it will do, it becomes less and less desirable for me personally. I will just look for somewhere else to invest the money.

Ok, I misunderstood. I saw where you quoted 3,000 and 2,000 but those were both slave versions. I would never be interested in something like that. I do work in the field, and don't need to get caught relying on someone else to get the job completed. How much is the full version?
-
Yaser, I am not able to make much out of the list on the website as to what the tool will do.
When you buy the full version, atmre you able to do all cars without the $50 charge? Do you have to buy software packages like other tools, or do you have full access?

It seems like this could be a real money maker for those who have a lot of these cars in their market. If the dealer is the only alternative, you could charge a lot, and still give substantial savings to the customer.
I am interested in a group buy, depending on price.

Okay. I thought you were trying to eeprom a key.
