Just got this from PLMS development. Its an s13 sr20det daughterboard that allows you to tune your stock ecu. Whats great is that it comes with a 4 map switch. This allows you to have different tunes for different conditions like says higher octane, more boost, hot day, cool night, nitrous, water injection.... I've been tuning 300zx ecu's for awhile and now I get to start in on my sr. I already have tunes for bigger injectors, bigger maf's, and all that great stuff. And guess what? It was only $150 shipped.
