IVR

My fuel gauge was always lazy, I have a reconditioned orginal fuel sender. So I removed the solid state IVR and installed my old one. My fuel gauge now responds immediately and is accurate. Great tip

The realtime engineering IVR mimicks the OEM electro mechanical IVR.

At initial startup the IVR gives a full 12v to the gauges for a few seconds, this causes them to respond faster.

After that the IVR works as expected, a square wave up to about 6v then to 0 and back again.

Some cheap electronic IVRs only provide a steady 5-6 volts continuous.

I fried my fuel gauge due to a failed electro mechanical OEM IVR.

I bought the real time engineering IVR, it has built in fail protection.
