    It's easy to see if it's a 96 engine. Look for the crank sensor at the bottom right of the timing chain cover. Also, aluminum heads would indicate a F-body or Vette engine.

    Can you easily cross connect the O2 sensors on that car? Some, you can do that and introduce a new issue while trying to fix a current one.

    There is a 1-way sprag that prevents engine braking when the shifter is in OD or 4th position. Pull it back to the 3rd position and then there is small clutch pack in parallel with the sprag that...

    I would expect that the pressure regulator with the lowest pressure setting would dominate and control the fuel pressure of all 3 TBI units if your simply paralleled the inlet and outlet lines from...

    It sounds like the PCM is going into limp mode, caused by an issue with it not emulating correctly.

    I haven't done what you're doing, so I can't really help. But someone here would know. Maybe try...
  6. The hardware side of the PCM is the same for all...

    The hardware side of the PCM is the same for all applications, so it's not necessary to keep the CCM at all. Just connect directly to the PCM and flash it with whatever tune you want. You'll have to...

    Definitely lower those times and see what happens.

    Basically, the PCM adjusts the line pressure so the shift takes the time in that table. It's called adaptive line pressure or something like...

    That's an odd one. A shift kit should "speed up" the shift. But then, the new higher stall converter will likely "slow down" the shift. I use quotes because I'm referring to commanded vs actual shift...

    Not one O2 or UEGO sensor made has a clue about AFR numbers. Every O2 sensor display of AFR is due to someone having programming a lambda to AFR lookup for the display.

    Do you happen to mean that...

    O2 sensors read rich/lean or above/below stoichiometric. They have no clue what the fuel is and will switch at stoichiometric no matter what AFR stoichiometric occurs at. Used on E85 they would...

    Good to hear you found a quieter pump. I've read many times that Carter pumps are noisy. I'm running a pump for an older Ford port injection with external pump and it's quiet enough I don't notice it...

    User jthompson122183 here created a version called EEXTRA with even more stuff mapped, but many of the additions have no documentation about what they do.

    Here's a link to a thread about it, but...

    The PCM can't properly perform speed based shifting calculations when it doesn't have a speed signal.

    That's odd that TC and TP can't share a bin. The versions I have will swap the bin back and forth just fine. I haven't updated TC for probably a few years now because I hardly use it anymore so maybe...

    You probably need a better xdf definition file for Tunerpro, such as this one or the one at Steveo's site. AFAIK, Tunercat still does not have these tables.

    I've read the same story as yours multiple times.... He's been around a long time but too bad he can't get a tune for a custom build right.

    You could, and I have even done it to be just a little richer once since I had a car where I could feel the lean side of the AFR as the closed loop fueling oscillated. But, if you go very far then...

    To further explain. A narrow band O2 sensor only works to tell the ECM if the AFR is above or below stoichiometric (the "perfect" AFR). This means that closed loop fueling only works at the...

    Not likely. The engine will generally tune itself either rich or lean against the fuel trim limits when you accidentally swap the sensor wiring left for right. Sometimes, one side goes rich and the...

    You poked at it making the mess, right?

    That looks like typical potting compound used in a wire bonded application.

    The truck 0411 applications with a 4x crank sensor still use a distributor. You're not going to get CNP from that setup. It would require a 24X wheel under the timing cover.

    I looked at my LS1 and realized it's a pressed pulley. I had been looking at another GM with the big threaded fan and it had a bolted pulley so was thinking the pulley bolted onto the LS1 too.

    I see no reason you couldn't just bolt the fan onto the LS1 pump.

    If you get into changing accessories, you may have to use all the brackets and the damper/pulley too since that is a Corvette...
