Well I heard of a couple, like the JET chip but from what Ive heard they are a waste of $$$. I don't think there are any real performance chips made for the N/A's...But you could take your ECU into a tuning shop (look around im sure you can find some place on the net or even localy), And get a chip custom made, and tuned by profesionals. This way you could get the chip designed to what you wnat to do with the car, now and in the future.

If you take it in, you're going to get ripped off. You can buy the equipment to do it yourself for less money. Eprom programming is easy once you find out what each value does. Then you can alter it to suit your needs. Me and a friend are building an EPROM programmer as I speak.

It's not that easy to hack the ECU's code. Keep in mind that all you will be getting is machine language (assembly) from these chips and you will have to do a lot of guessing to find out what value is what and what addresses are what. You will need some sort of in-circuit digital test device to help with this (i.e. a logic analyzer, they're $3000). You will need to get the instruction set for the ECU's microprocessor (the processor is made by NEC and very old, so good luck with that) and you need to know what parts of the memory are instructions and what parts are data.

Just keep in mind that unless someone like ZombieSS or JayB can provide you with some documentation/info you are going to have a tough time reprogramming the EPROM. Also (obviously) you will need to know assembly language and have knowledge of control systems for IC engines to really be effective.
