    68 fuel gauge maxes out at half

    It is possible that the float arm may be bent such that it has the resistor maxed out thinking that it is full when it is not. This would require draining the fuel, removing the sending unit to bend the float arm to remedy the situation. The task could be performed on ramps but is a lot easier...

    Engine EEC-IV Problems

    I'm aware that the Binary Editor and TunerPro RT file extensions are different making them not cross compatible. Also, usually not (within a method) compatible across strategies. As far as TunerProRT/decipha method, the bin/defintion files are paired up. I'm using CRAI8 based bin variation with...

    Engine EEC-IV Problems

    When I purchased my Quarterhorse, at the time it was only available to purchase with BE. I already had TunerPro RT installed on my laptop and had gotten familiar with the way that it works. I'm using it in an EEC-V situation. I would like to use BE on the Fox body Mustang but I haven't yet...

    Engine EEC-IV Problems

    @FastDriver Are you using the 'decipha' files and TunerPro RT, Quarterhorse etc? I'm just getting familiar with the equipment and getting to know my way around some different bin files.

    Engine EEC-IV Problems

    @FastDriver I'm just now looking in the GUFX related file/s and haven't yet gone through and identified the "switch" per say. I'm looking for the 0 or 1 value in the parameters.

    @Mustang5L5 @EDDIEM75 My apologies to the OP for getting off of the original issue at hand but these discussions can turn into learning experiences for others too. When I turned 14 and quit working on bicycles to work on cars and trucks, I knew already knew several important things, three of...

    Engine EEC-IV Problems

    @Mustang5L5 Interesting information about the Fox body, auto, T-5 ecm differences. Direct me towards some wiring diagrams for 1988 and 1989 5.0s. Now I'm wanting to avoid making a mistake with these two different pcms while working on brother's '88 converted to mass air and a factory AOD. ADDED...

    Home laptop settings changed mysteriously

    I like having my multiple page tabs up top. Something has mysteriously changed what I'm used to. In the pic, see how the tab is at the top middle? I'm used to a tab at the top left with a + sign to the right of the first tab to click on to open another window. What has happened? Earlier my wife...

    Engine EEC-IV Problems

    @EDDIEM75 Ok, on your thoughts about the ecm, post etc. I'm curious how close you might be to my location. I'm near the AL/TN line. Do you have a friend or associate that has the same year Fox body that you are dealing with? I have to leave the house again today to go back to my Shop but while...

    Engine EEC-IV Problems

    If you haven't, it may be a good time to take out the ecm and inspect it. It's easy for humans to make procedural mistakes and I am human and constantly reminding myself to disconnect the vehicle battery before R&Ring eecs, ecms, pcms etc. Removing it and remove its cover; and giving it a good...

    Engine EEC-IV Problems

    Did you look at the spark plugs today? I didn't catch the shop slang "brick". When I purchased my scanner, The Snan-On guy referred to it as the Snap-on MT2500. A Mech/Tech friend called his, a Snap-on Scanner. I'm in a partnership (very small) garage and there is already something else in the...

    Digital Tuning Chip tuning in 2025, what are my options?

    Yes but it is handy to have a wiring diagram for the particular vehicle that you are working on. That's why the car companies made them in the first place. Her is the link that I overlooked adding this morning. 1992 Mustang wiring diagrams E-bay search results.

    Digital Tuning Chip tuning in 2025, what are my options?

    @Dontknowchit I only had a minute to start a search for a 1992 Mustang wiring diagram. I think on your Ford, the gauges are wired independently from the ecm wiring. Oil pressure, ECT. I'm not sure about the tachometer. My '97 tach feed is from the pcm. I have added a real oil pressure gauge and...

    Needed parts for quarter horse.

    E-85 type of fuel can be tuned in too. Moates should have some J3 chips back in stock soon. It's possible in their temporary absence, interested people are purchasing from them to make up for them being gone. ~2 years ago when they had closed, now we know paused, just to get the QuarterHorse, I...
