Most PC3's are getting pretty long in the tooth and it's pretty common for them to start dying off. What year ZX do you have? That makes some difference. Also, ping KZScott, he's in Canada, but he's been in contact with "the guy" who originally helped Hack these early model ECU's for editing.

I can increase the rev limit, change the fuel maps, change the ign timing to whatever you want, adjust the coil dwell time if you have a turbo or nitrous bike and need a stronger spark, adjust the ram air compensation if you have a big motor that leans out up top for a lsr run, adjust the warm up and acceleration enrichment for larger inj, and theres a few things that are there that im not going to touch as i dont know exactly what they do yet. and as an added bonus, the ecus are basically programmed with 2 sets of everything and switch between map 0 or map 1 based on if a wire is jumpered in an unused connector in the tail, so it can be totally stock in one setting and then have the modified conditions used if the wires are joined (and the bike shut off and restarted)

oh and it doesnt need to be cut open, i did it by using some "unused" pins on the ecu

ZX12R 16bit ECU reflash

The original programming interface discovered by RidgeRacer involved "notching" the ECU to access the processor's BDM port. A $500 BDM tool was then used to read or reprogram the flash memory. Psyche and RhinoPower later developed a cheaper DIY parallel port BDM tool, but that also required cutting into the ECU.

Last fall we discovered that the ZX-12R (21175-10xx) Denso ECUs could also be read and programmed via an OBD (k-line) port on ECU pin 31, so we no longer had to cut into the ECU. Interfacing the OBD (k-line) to a computer USB port is done with a VAG-COM KKL (CH340 chipset) OBD2 cable, but you have to make an adapter to connect the cable to the correct ECU pins and an external regulated 12VDC power supply.

A Flash tool software package is then used to communicate with the ECU for reading and reflashing. The process for making modifications to your ECU's 96k bin file hasn't changed and an editor (like RomRaider) and definitions for your ECU model are still required. The Flash tool software also allows you to read the ECUs NVram, where the (yoshbox/Teka) fuel trim settings are stored.

That being said, if you're just looking to tune your fuel maps following some basic mods, get a Power Commander. If you're into more serious mods and need to change rev limits, TRE, MSO/MS1 maps, ignition timing etc. then you want a reflash. Just bear in mind that you can only reflash an ECU a few hundred times and that some ECUs can't be reflashed at all.

If you're still interested reflashing your own ECU, you should first get the OBD cable, build an adaptor and try reading your ECU. After that you can install RomRaider with your definitions to see what modifications you can make to your ECU. Then if everything goes well, you can decide if you want to get a flash/erase license.

Got to admire you guys you certainly know your stuff....guess everyone to their own, all the years people have been milling their ECU's then you find the Holy Grail of doing the flash without the cut....think someone already does the 32bit ECU's without chopping ?

ya the 04 05 32 bit can be done with woolich, be nice if some guys gave them some competition to lower the cost
