Message I put in Nismo 555cc injectors in my 93 tt a few years ago. At the time I had already bought the JWT Stage III ECU, it was only $100 (a lot cheaper than a programmable ECU) to have the EPROM updated for the bigger injectors. Now I am thinking about upgrading a bunch of other things, maybe over time, and so it seems like a waste (both time and money) to have the EPROM updated every time.

When I got the 555cc injectors, I remember really well there was a complete ECU replacement computer available, including software, that would let you program in constants, such as injector size, spark intensity constant, valet mode max RPM, etc., but it was like $600 and I didn't think that my upgrades at the time were extensive enough to need that, and the $100 EPROM upgrade seemed a lot more reasonable to do.

I cannot remember what the name of that computer was because it has been several years (it had its own web page), and I've searched and search, all I find is AEM programmable computers which are generic. This one was a direct plug and play for a 300zx, and it completely replaced the entire stock ECU module. Does anyone know what I'm talking about? Can anyone help me in the right direction?

Again, although it would allow it, this unit did not require knowledge about fuel mapping or extensive tuning experience like most custom computers, this just had field for constants you could change, like max fuel injector capacity and so on. I know I saw it and read about it, I just can't find it now.

Thanks for any help
