Which cluster is best to use for an ls1 dash swap. I have a 98 set up ready to go but im curious about the gas gauge, I know the 97 used the 90 ohm sender which is the same as ours and the 98-02 got the signal from the bcm. For people who have used a 98-up cluster, is the gas gauge still accurate? thanks

 

You have to use the gas tank and stuff out of the 98 I think and then it should work

 

I used the 97 Z28 150 mph cluster and gas gauge worked fine.

 

The LS1 gas tanks use a different ohm sender (check the lsx swap forum here) than the thirdgen 0-90ohm. So - you'd either have to use a different sender in your thirdgen tank or use the 4thgen tank.

My recommendation? Keep the thirdgen dash and make it work with the ls1

 

I'll just use a 97 cluster then.

 

Did the 97 cluster work for you?
I have a 98 dash ready to install but im having the same question.

 

Yes, the 97 has everything functioning. The only problem with the 98 is the fuel gauge.

 

Didn't the LS gauges use a serial data line for the communications?
