I have not seen any vin info written to any ecu from 1998-2002. I have replaced the ecu in my LX470 with 4 different ecus while experimenting and never have seen any vin info. i have seen vin info written to ecus for vehicles after 2002

Yes, the chips i have been giving away are 93c56 eeprom.

Awesome! Im glad it worked for you. I have mailed out quite a few of the chips and have only heard back from a couple of people who have installed them. I think most of them are afraid to do the swap. Doing the programming for the fobs can be aggravating if the actuators are weak.

I have been instructed to look up your threads concerning new ECU's. I may be headed that way. My keys are not working to start my 01 rx300 awd.
From what I am reading it looks like I may go with your idea. Are you still giving away chips? I promise to write about the results. This forum is keeping the ole girl moving.

Sure, I've been needing to burn a few chips. Just send me a message with an address to mail it to and I will get one sent out.
