XTOOL D7W Review: Is This Bidirectional Scan Tool Worth It ?

[@fredguerra4917]

Nice video. Tested my 06 350z. But I was not able to locate the long and short fuel trims. Is my scanner defected or my 350z does not have the ability to provide them via scanner? I contacted xtools but I have not heard from them. I welcome any input.

Thanks,Sir. Long and short fuel trims are used by the engine control unit (ECU) to adjust the air-fuel mixture. The long term fuel trim is based on the average fuel trims over a long period of time, while the short term fuel trim is based on the most recent engine operating conditions. By viewing the long and short fuel trims, a mechanic can diagnose problems with the engine's fuel system. If you are unable to locate the long and short fuel trims using the XTOOL D7W scan tool, it is possible that your scanner is defective or that your 350Z does not have the ability to provide them via scanner.
