I can't get the Rpm to display accurately in the monitoring software. I hooked the rpm input wire to the white tach output on the PCM. Btw I have delteq.

It reads correctly until I rev it past 3000 and then it reads extremely low like 400 rpm.

I've talked to Dynojet about this and they want me to send it back. I just don't want to run all the wiring again.

Has anybody been able to get their rpm to work on Dynojet Wideband Commander?

 

I don't have the RPM hooked up. I have never used the WBC to log, I've only used it for a gauge to this point. That will change this year though, as I hope to be getting into it's other features.

But, since I run a Mallory box, I'll probably use the tach output on the ignition box.
