Hi, I use 2 settings in my Hondata, but the change of the chip is not practical. I'm thinking in make a circuit that I can install the 2 chips and use a switch to change from one to the other (of course with the ignition key off).

Some here trie this or have comments?

Thanks in advance

 

I would like to see that, and possibly purchase a couple.

Let me know the development goes.

 

There is something like a double chip. I dunno how it's done but it uses a single 29C512 chip. No need to use a circuit just need to play with the addressing of the chip.

 

I read about that, but it remaining the need of a switch to change the base I/O adress the ECU see.

I think that use of 2 or more 29C256 is a good solution, in example you have settings for Street, N2O and Valet.

 

for a good idea!!!
