I appologize if this is too far off topic, but I notice the comment about the PSM/ABS issues with remapping. I get a failure about once or twice a month with a Cargrafic chip (installed in late 2005). Is this unavoidable? And, is a chip old school at this point?

Apparently, some who offered their input on product and vendor have already been removed. Why?Knowledge is power.

Can someone explain, how the ECU keeps the stock or upgraded maps when the car battery goes bad? Lets say, that it takes about a week to get a new battery.When you first start the car , does it run stock, or it will run with whatever program was running at the time the battery went off?
Thanks

Have you contacted Cargrafic or the particular vendor?

No, I will not go through the supplier because of not so great experience. I will try Cargrafic. I am curious about the difference between flash and chip and why someone would chip a car in late 2005 (my own ignorance here) when fashing seems to be a more efficient way to get it done?

Now I haven't made up my mind yet....but sometimes the price looks pretty good

The chip is more expensive? (mine cost 2K). If its any help, the Cargrafic I have was suppose to be a top quality map. It performs very well with very smooth response every where in the power band, pulls very hard up to 200 rpm over red line showing .9 bar boost and 1 bar with 100 octane. No rough running at idle or just off idle. But as I said it throws PSM/ABS codes periodically. Not really sure if the systems are actually off when it does this. A restart clears the codes. Seems to me if its just code being modded, the flash would be a better way to go if for nothing else but the price differential.

Is this right Stephen? I don't want to put words into your mouth.

Same difference it sounds like if either way you need to do something
to ECU (reflash with hand held switcher, go to dealer if you are close and
that is convenient, or send in ECU)when battery goes dead to get back
previous levels of performance. I call this inconvenient.

Yes Marty that is correct.
Reread my post. The process we use is the same protocol as the factory flash. The stored stock program will revert on battery loss. Read: it will switch, not write. It is physically impossible for the ECU to write to itself. So let me make sure that I can confuse a few more people
If you have a single flash, meaning only the performance file when you disconnect the battery this is still present. It can only be changed by flashing in a different program. It will always be there unless some physically removes it.
If you purchased the options for a stock program, valet, race or performance then the unit when the battery removed will revert (switch only not write or copy) to stock. This is in case you can not get the battery to work at all and do not want the dealer to know it is modified.
You get the new battery and when you get the car back you simply hook the switcher into the OBD2 port as you would to switch and simply push what ever file you want to bring up. You do not send the ECU back. All the files are stored within the chip. Again, they are flashed (copied) into the ECU. It is still there, you will just need to switch it back when you get the car back.
Let me know if this helps or makes it worse.

To be fair, there can be operational advantages of chipping an ECU (ie. adding physical memory which could conceivable allow for more features, functionality, etc,.) But I don't know if anyone has taken advantage of that potential (if it indeed exists for this particular application).
One unfortunate problem you may have to deal with is the possible inability to flash your now re-chipped ECU. If you do chose to go down that path later, you may have to revert your ECU to standard condition.
It's probably best to talk to the representitives at Cargraphics if you need more specific answers to your questions. I'm just going off personal experience gathered from chipping and flashing various ECUs for the last several years. Your actual mileage may vary.
best regards,

Bench flashing in house. OBD2 harness and cables at my desk.
There is not one option that we can not take advantage of through flashing. It all depends on whether one has the full programming ability to do so. This is one of the reasons we canz remap the eGas as well as the cam profile on the new kits. There is no reason to add more memory to the 800BB chip. It carries enough physical memory to run all 2700 maps x 5 with room to spare. This is how we allocate the additional programs. The VW and Audi which use smaller chips also have more than enough physical memory.
main chip
Chipped ECUs are a thing of the past. To remove a 7.8 chip it is epoxied 8 times to the board with over 40 legs. So one has to be able to remove those legs and epoxy without lifting a leg. I have done hundreds and can tell you that there is one way only that works and all the fancy tools out there do not do the trick. Not even the 1500.00 lifters.
Damaged board from another vender. Damaged from removal.
Epoxy on the chip.
Simply reading down the ECU will not tell the whole story either. Some of the maps remain in the system and have to see a request (physically) to dump that information. I will not go into great detail, but I will assure you that on a daily basis this is done. It is a software/physical issue that does not require removal of the chip.
Old style burner
Embolizer chip.
Any chip that does not have an encypter and I believe CG and TA both use EVCs 600 or equivalent. These can not be written over without removing the chip. They will have to go back to the supplier as most remove the embolizer numbers and allow it to be an "open" ECU. This means that it would have to be programmed as a "new" ECU.
EVC 600 Encypter
