Chipped car was no issue with the re-flash but with Edit the only option is to find a dealer who is happy with your directions "Do NOT Re-Flash this vehicle without permission" and string a line about it's all running so well with the current flash. There is another way to get the PCM and Edit re-set with new software - but it's expensive and only funny looking back...see my ACT Edit thread and you'll understand.

Spot on Zap, I think you're 100% correct.  I paid $75 to have mine reset after I bought it second hand.

XXXR6T, if you work that out mate, you'll be one popular fella!!  If you're to believe what CAPA say, even they can't do anything about the 5 life situation - they reckon that once those lives are used up, the box can still be used but has to be sent all the way back to SCT in the USA to be reset first!!  :spoton:

Well you have to look at it electronically. Most memory applications have a lot of similarities between them. The flasher unit does a couple of things... it stores a heap of information in memory... namely EEPROM (electronically erasable programmable read only memory). It also interfaces between the memory bank and the ECU so it performs a data transfer function.

As with a BIOS in a computer, the flasher unit is resettable. This can be done either electronically (applying a voltage to a specific pin), physically (removing the ROM and replacing it), or another way is exposure to sunlight (EPROMs have a light sensor on top of them and exposing this to sunlight for a while erases the stored info on it).

Now there must be a counter which stores the number of times the flasher unit has downloaded a tune into the factory setting, and it must be full at 5 times. Like the other ROMs in the flasher this will be erasable somehow... unless it's the type which is written at manufacture and needs to be replaced. If I could have a look at the internals of one I reckon I'd be able to find out.

Ok so who's confused? :spoton:

I think the question you should be asking is who's brave enough to lend you their CAPA box to give it a go?! :blink::spoton:
