Injector driver boards
I'm looking for the schematic for the injector driver boards mentioned in the faq. It doesn't seem to be on diy efi anymore. I know there was a guy that was building them but that was a long time ago and so I thought I would try to build my own. If any one has them if would be great if you could share.

Re: Injector driver boards
look up the data sheet for the LM1949 injector driver. the app note schematic is pretty much the injector driver circuit, minus a little bit of logic. Each circuit can drive a single TBI injector with the values shown.
