I researched this extensively on the site, but never found an answer. My long-running 7MGTE swap/restoration is out on the streets again as of this weekend. I have the typical MSD adapter wired in, but my RPM is reading way low on the Digi-Dash. I would estimate about half of what it really is based on my ear vs. what the gauge is reading.

Any advice from the old sages on here?

Where is the adapter mounted? There are known to have short lifespans. The one I mounted in a buddies 1jzgte swap, we stuck under the hood in the path of a cold air supply. So far so good.

It's right by the fuse box. Basically new, I'd be a bit surprised if it somehow cooked itself already. And clearly some signal is coming through.

Idle for example reads about 400rpm. The throttle holds open slightly without physically lifting up on gas pedal. Sounds like 1200-1500 but reads 700-800. Wastegate dumping letting off the gas at when it reads 1000rpm.

Will try to take it for a spin tomorrow and record speed / gear / rpm readout, maybe I'm crazy.
