60 hp chip

[deevergote]

All that had to be done on my ECU was desolder the CPU chip from the board, solder a "mini" board in place of that. The CPU chip is soldered onto that mini board, and the socket for the eprom is right next to that.

I wouldn't see why it would be much more difficult than that for the Accord?

Honda ECUs merely require a chip to be soldered in, or a socket that will accept the chip (so it can be removed easily.)

It's the programming that is difficult, not the physical act of "chipping". Nobody has broken the code for the Accord and Prelude ECUs, so they aren't tunable. If you break the code and write a program to support it, sure, it can be done. But those things have already been done for the Civic and Integra computers, and we're able to use those with no problem.

Thought jet chips were just A/F controllers?

Jet may have, yes... and those are the only things you really have control over with the Accord and Prelude ECUs anyway!
