i am trying to write a file from my toyota dash. gq4x
was told it needs to be read/written at 16 bit.

the 93c66 comes up as a generic device for 16bit. The IC says "CSI" brand. CSI in the list only has 8bit.

When i write using the generic 16 bit the cluster goes crazy and doesnt work.

When i write using 8 bit CSI it works but mileage blinks 999999 if its corrupted.

Anyone have any success writing toyota 93c66?

I also tried to add in devices.txt
Name="CSI93C66 (16Bit)",ID="XXXX",Class="93C66A_16Bit",BufferMode="16BIT",Category="SERIAL_EPROM",MFG="LSI/CSI",Speed="4";

but i get the error" The Class 93C66A_16BIT is not found" "Parse "Devices.txt" error on device. Did i do this wrong?

Just curious if this will make any difference than using the "generic" 93c66 16bit setting? that i already used that failed.

Are you talking about the 93C66B?

yes, well i tried it and same result. I dont think the programmer is writing correct in 16bit for this chip. Tried multiple files with same result.

If the files and chip are identical problem is with your calculated odometer value.

i even cant load back the original file, even got another original file online and same result.

whats odd the cluster works when i load as 8 bit, completely messed up when 16bit. bin is 16 bit

Did you read the original file in 16bit? Probably should be done in 8bit since the cluster works then except the calculation must be bad.
