I am looking to datalog boost within Nistune. It is very possible and people do it all the time. What kind of wideband do you use? If you use an lm-1 or lm-2 you can access up to 5 auxillary channels (0-5 volts only) within nistune. If you are using the lc-1 you may be able to use the innovate aux-box and if you aren't using innovate products you can certainly use a DLP converter with the boost sensor of your choice (including the one on your boost controller .... hence my post). I'm actually going to overcome my laziness this weekend and just pull some wires through the firewall. Gonna pull a line for RPM,MAP, and TPS as I wanna datalog at the track without my laptop being on (LM-1 has built in data recorder).
