    Thanks for the quick response. I guess I shouldn't do it then.

According to the warning label on new WBO2 sensors, if the ECU is powered on with the wrong WBO2 sensor selected, damage will occur. Aside from correct software programming, ensure there are no ignition misfires or exhaust leaks upstream of the WBO2 sensor(s).]
    Danny, sorry for the grave digging on this post, but wanted to ask a couple questions. The excerpt above talks about damage will occur if they are powered with wrong programming. Is that damage to the ECU or the sensor? Thanks.

    It damages the WBO2 sensor.

    Thanks for the reply, I'm pretty sure I wiped one out. I'm gonna run a few more tests, then get another on order. Stupid mistake, stupid reward.

    Danny with the LSU 4.2 WBO2 sensor, can you use the Holley 558-463 WBO2 Adapter Harness from the Terminator X Kit to run a aftermarket or OEM (I.E. VW) LSU4.2? I ask because of the availability of them and they still have the calibration resistor built-in. Thanks.

    No. The Terminator, HP & Dominator EFI systems use Holley's proprietary Bosch LSU4.2 & NTK UEGO WBO2 sensors (LINK).
    The Terminator X & Sniper EFI systems use the Bosch LSU4.9 WBO2 sensor (not the LSU4.2) and the EFI software is programmed for it.
    The Holley 558-463 WBO2 Adapter Harness (LINK - item 9, page 4) adapts the Bosch LSU4.2 & NTK UEGO WBO2 main harnesses to the Bosch LSU4.9 WBO2 sensor.

    Danny, any idea if there will be a software/firmware update that will be made so we could go to the LSU4.9 WBO2 with the jumper harness? Or a CAN Bus setup for WBO2 that would work for fuel correction?

    Not that I know of. As always, you'll have to contact Holley Tech Service (LINK) for future product release/support availability information.
