3.8 and 4.2 V6: Please read

[BrianA]

A few things that would make life much easier for all of us. These are simple things that can make a difference.

a) thread Subject - please make the subject (title) of your thread reflect the actual content. This makes it much easier to browse the threads and find what you are looking for. Also, it allows newer users an opportunity to look back and find interesting threads that might have been posted to before the new user arrived. For example, if you have are looking for advice/personal experience on the benefits of adding headers, title it somethign like "Headers: advice/opinions/experiences?" RATHER than "performance question".

b) rather than make repeated posts one right after another to the same thread, use the "edit" function to add to or change your previous post. You have 60 minutes to edit a post. Sometimes I will notice 2 or 3 posts in a single thread, all by the same user, all with 10 minutes of each other. using "edit" will save bandwidth and will help keep the FTE website running as smoothly and efficiently as possible.

c) try to avoid SHOUTING. Typing in all caps makes reading your post more difficult. I believe that some folks are less inclined to read through (and respond to) a post in all caps.

d) don't post a new question in someone else's thread, and expect it to get attention. Especially so if your question/problem is unrelated to that thread. If you have a question or a problem you need help with, start a new thread.

Thanks to all.

Seems pretty often someone asks about using the digital trip meter as a tach.

Here is how you do it:

To enter the test mode, depress and hold the instrument cluster SELECT/RESET button, turn the ignition switch to the RUN position, and then continue pressing the SELECT/RESET button (5 seconds) until tESt is displayed in the odometer.

The SELECT/RESET button must be released within 3 seconds of the odometer tESt display to begin the dealer test mode.

Start the engine with the odometer in test mode.

Depress the SELECT/RESET button to advance through the following steps:

Here is what you get:

GAGE: Activates gauge sweep of all gauges, then displays present gauge values.

r: Returns to normal operation of all micro-controlled indicators and LEDs.

EE: Displays the hexadecimal value for EE level.

dt: Displays hexadecimal coding of final manufacturing test date.

dtc: Displays continuous DTC's in hexadecimal format.

enG: Displays the English speed in MPH. Speedometer will indicate present speed within tolerances.

m: Displays the metric speed data in kph. Speedometer will indicate present speed within tolerances.

tAc: Displays the tachometer data received from the PCM via the SCP network within tolerances. Tachometer will indicate present RPM.

FUEL: Displays the code (0-255) for the fuel sender input to the HEC. The fuel gauge will display a filtered fuel level value. This filter will keep the pointer from moving suddenly or erratically.
255 open send +/- 0
232 full stop +/- 0
215 Full mark +/- 10
178 3/4 mark +/- 8
138 1/2 mark +/- 7
93 1/4 mark +/- 5
41 E mark +/- 4
54 Low Fuel (0-59)
0-18 short (0-20 max)

OIL: Displays the code (0-250) for the oil pressure switch input to the HEC. Oil pressure gauge will indicate present oil pressure. Normal oil pressure (greater than 6psi) will display a value between 000 and 176. A low oil pressure or an inoperative engine oil pressure switch (less than 6 psi) will display a value greater than 176.

dEGC: Display of engine temperature in Degrees C input from cylinder head temperature sensor.
49 C "C" mark
60 C Normal band start
120 C Normal band end
-40 C No SCP message for 5 seconds

bAtt: Displays the code (0-255) for the battery voltage input to the HEC. Battery voltage gauge will indicate present battery voltage.
93-102 6.2-9.1 volts, low voltage
115-124 8.5-10.7 volts, Normal band start
215-225 15.8-18 volts, Norm band end
230-241 16.9-19.1 volts, high voltage

rhEo: Displays the present decimal rheostat dimming input, 0-255

rhi / rhS / rho: Not used.

Cr: Displays the current RUN/START sense input. Display will show -h for high input with the ignition switch in the START position and -L for low input with the ignition switch in the RUN position.

PA-PE7 not used.

GAGE: Repeats the display cycle

I will over the next couple of months be cleaning this up.

Moderator I would greatly appreciate any help on this, old links remove, links that don’t work remove.

PLEASE do not add to this at all. Until we get the “stickies” sorted out.
