I am a die hard Datsun Z car fan and have owned one (or two) for almost all of my driving years (15). However, I am now Z-less and perfectly content to work on my CRX. BTW, I love the CRX as it has MANY qualities that I often wished for on my Z. Anyway, I did a lot of research on programmable EFI systems for my Z but never bought one. The TEC units are certainly proven and are good ones. Two other units are at www.sds-efi.com and at www.wolfems.com.au
I personally loved the Wolf EMS unit. It was less expensive than the TEC and had both a hand programmer and the ability to support a laptop interface. At the time, it was the only one that could do that. That is my limited knowledge on the subject but the Wolf had my vote. Craig
