datwsheet I just figured why not try with my arduino and learn a thing or two. Hi, What do the professionals do when they need to change instrument cluster?
Well the good news is its a late model and I have everything I need from a junkyard for very cheap. There must be a procedure to clone the new cluster from the old. I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out.
I’ll look into that cloning. TomGeorge Design and Repair of industrial control systems.
But what is the format of the data? No clue how do I go about getting this info?

Datssheet not that easy. I just wonder if moving the chip might be a solution. I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher. Everything runs on smoke, let the smoke out, it stops running Writing to the eeprom isn’t too hard if you have access to the pins. If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this?

It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. Is this something the arduino can handle?
Ill see what I can do about separating that chip. Given that it’s ‘in-circuit’- I presume soldered – you’ll probably need to break the leads to CS, SK ,DI DO, so as to prevent the existing curcuitry from preventing your operations. If you had the appropriate sw from the manufacturer I bet you could do this via the OBDII connector – but I also bet they’re not telling you how!
Just as the title states I wish to flash a 93c56 Xatasheet in my jeep cherokee gauge cluster because my old gauge cluster has malfunctioned and the new one will have incorrect millage on the odometer.
Is there a connector next to this chip which does this? I know this guy here did it with an off the shelf programmer, which is quite expensive compared to the arduino I all ready own.
And if so how would I go about doing this? It may be cheaper and less risky to go to a Cherokee dealer and get him to do it Not to mention so many people in the jeep community have arduinos and would benefit from this.
