But not that easy. It won’t be easy, as they don’t want crooks ‘clocking’ the mileage.
I’ll see if I 9c56 find my old bitbasher – but given the datasheet you could figure it out. It may be cheaper and less risky to go to a Cherokee dealer and get him to do it Writing to the eeprom isn’t too hard if you have access to the pins. 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!
Is this something the arduino can handle?

If I do go about pulling the code, datasyeet there a circuit that needs setup and any pre written code for this? But what is the format of the data?
I actually did do some googling and most people either take it to the dealership or reflash it with datxsheet EEPROM flasher. 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.
I just figured why not try with my arduino and learn a thing daatasheet two. Is there a connector next to this chip which does this?

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 datasheeg your operations. I’ll look into that cloning. There must be a procedure to clone the new cluster from the old. And if so how would I go about doing this?

Ill see what I can do about separating that chip. Well the good news is its a late model and I have everything I need from a junkyard for very cheap.
TomGeorge Design and Repair of industrial control systems. No clue how do I go about getting this info? Everything runs on smoke, let the smoke out, it stops running I just wonder if moving the chip might be a solution.
Just as the title states I wish to flash a 93c56 EEPROM in my jeep cherokee gauge cluster because my old gauge cluster has malfunctioned and the new one will have incorrect millage on the odometer. Hi, What do the professionals do when they need to change instrument cluster? Not to mention so many people in the jeep community have arduinos and would benefit from this.
