My car currently is running CROME tuning on a P28. I want to use my laptop to log certain things, including A/F ratio. I intend to buy an LC-1 Lambda, what do I need to log this info and integrate the A/F readings on my laptop? Xenocron has a logging cable for only $30 that needs to be soldered onto the ECU. I assume then all I need is to download CROME and use the logging feature on the software??? anyone done this before that can tell me what I need to buy?
