View Full Version : 190E Performance Tuning ? altan 04-19-1999, 08:05 PM I notice the mechanic took out the carpet on the front right sit and set something under it during the car tuning. What is he try to tune ? Is it some performance related tuning ? (year manufactured 1988) Thanks in advance. M.B.DOC 04-19-1999, 08:26 PM One of the only items under the carpet is the cruise control computer. Nothing inside the car could help with performace tuning. The connection for the oxygen sensor is under the pass. side carpet, maybe it needed replaced? altan 04-20-1999, 11:28 AM Thanks MB Doc, I have clarify with him, (my mechanic), he need to disable the oxygen sensor while perform the CO tuning. Thanks again. M.B.DOC 04-20-1999, 09:40 PM I hope that that your technician used a Lamda meter to set the fuel mixture after testing the CO. THE COMPUTER likes to control the fuel mixture at an even on-off ratio!!

Only adjust fuel mixture with a Lambda meter. ------------------ Benzmac: ASE CERTIFIED MASTER AUTO TECHNICIAN LEAD TECHNICIAN FOR 14 BAY FACILITY MERCEDES SPECIALIST 8 YRS PARTNER IN MERCEDESSHOP.COM altan 05-12-1999, 04:05 AM How does the lambda meter look like and what does it measure ?
