If you do need to replace it you can get better stuff for less money these days. Sometimes taking 5 years off is a good thing since technology marches on. AEM sells wide band kits in the $150 range. If you already have a sensor then you can save even more money.
They've had the little gauge for 150 since '09-ish, yep it is ok. I believe
My Buddy Evan still has one one his blown 392 Magnum.
They don't have anything that Will log and play back in that kind of
Price range, which was the appeal of the fast meter. No laptop required,
On screen playback, but it's only appealing if it works
. When working the fast can play back 50 minutes on its own display.
