OBS With LQ4 & 411 PCM Gas Gauge Fix

[capricefrk013]

I cant find this anywhere. I am using HPTUNERS and have the setup in the title. I cant figure this out. I know it can be done with HPTuners.

Anybody know how to fix this problem?

Thanks in advance.

The old gauges use 0-12v signal straight through the float in the tank. The newer pcm requires 0-5v signal via newer style sending unit.... only way I could get around this to use old gauges and keep new pcm happy was to add the newer sending unit to the tank.

So basically I have two floats in the tank. The original to control the gauge..And the newer style to feed signal to lsx pcm.

I just put in a a whole new fuel pump module because mine went out and I dont feel like going through all that again to do what you mentioned. LOL
