Pyrometer kits must be plugged into a controller prior to plugging in OBD2 port or the “RaceME EGT sensor temp” will not show up in the gauge selection menu. If it is already plugged in and you can’t find this PID, The directions are as follows: Turn key off–> unplug OBD2–> unplug EGT sensor cord from controller–> wait 30 seconds–> reconnect EGT sensor to controller–> reconnect OBD2 –> power up tuner with key on operation–> select gauge you wish to modify–> find “RaceMe EGT sensor temp” under the temperature menu.
DO NOT try to make ABS changes while you are driving. This is not a real-time function. The purpose of the ABS menu is to correct speedometer for different size tires. This has to be done with the key on – engine off to be effective. Failure to do so may disable the ABS module.
When plugging in micro USB cords, the type “B” logo on the cord must be facing down on both the controller and the monitor. Damaged socket due to improper connections will not be warrantied.
There is a differential pressure sensor bolted to the passenger side of the transmission. This sensor remains active after delete tuning. This sensor has two hoses connected to it that attach to the stainless lines on the exhaust. This sensor has to remain open to the atmosphere. Do not loop the hose around to the other outlet of the sensor. This may cause pressure differential. Its recommended leaving about a 6 inch tail of hose off the sensor so that if mud should pack up in there, it only plugs the hose and not the sensor. Should this sensor fail, it must be replaced.
The most often cause for this message is the regenerative timers that the ECM records within itself. Once these timers reach a predefined value, the ECM requests that the exhaust be serviced. To reset these timers, a Witech Diagnostic scanner or equivalent will be required. These timers are as follows:
Another reason for this message is that the fuel pressure relief valve in the front of the fuel rail is weak. This relief valve is intended to relieve over pressure in the event of a pressure spike. The cure is to get a shim kit and shim this valve or replace it with a new one. If you are wondering why a code reader can’t delete this, and because there are no DTC’s, it’s that these are simple counter’s which give the ECM information about re-generations and the count of over temp events. At an assigned value of such events, the ECM thinks there is a problem with the DPF and comes with the SEE DEALER NOW message.
