    No matter what I adjust, all three bumpers on a PF swapped high speed are incredibly limp and weak.

    Any ideas on what could cause this? It’s weird that it’s all three... I replaced the switch stacks which have the cap/resistors which I’ve checked. Should be wired fine but could this be the caps?

    35v at the lugs.

    They just kinda weak plunge and I can hold them up with my finger. Little resistance. So frustrating.

    I tested this. Activating these pins absolutely fixes it and the coils fire much more powerfully.

    What’s the remedy here? Just repin the Connector on MPU?

    Ok: on it. Anything else it could be? Just because I am always wanting to learn!

    Replaced the connector with a trifurcon molex. No change.

    I’m thinking it’s the new switch stacks I put in. They have different tabs than the originals and I think they just aren’t wired right.

    Originals

    Yet I still managed to screw it up! I really can’t see how.

    I completely reversed one pop and went back to the old switch stack, cap, diode, and resistor. And pop was perfect.

    I legitimately can’t see why. Everything should be wired the same, even without the tie points.

    I have never heard of such a thing. Fascinating. That is probably it as getting the leaf contacts just so was also tremendously frustrating.

    I’m going to just crack the switch stack and replace the skirt/cup switch with the original to test. Less soldering!

    The latest is that returning to the old switch fixed the issue. Not sure why.

    Wouldn’t a shorter coil firing time result in weak pop action anyway?
