Dont over look the plx dm6 I personally couldn't monitor a live wideband while boosting and trying to keep eyes on road the plx will keep peak and minimum values for you stored map them out on a graph and show them on colourful lights like an aem. Rob-h on here with the insane 4efte n/a said about them I took his advise and got one it can be linked with 6 other modules to show thinfs like boost egts inlet temps oil pressure and temps etc etc. Doesnt need calibration and uses the bosch sensor same as most widebands Youtube them Also supports data logging And can be linked to ecus
