Hy all

after my ls1 swap ( of a 99 camaro) into a chevy pickup 51, i am looking for speedo / tachometer which are working with the the original pcm signal...

Which gauges would recommend ??

Thanks

Pretty much any aftermarket gauges will work. I have been happy with my Autometers.

Thanks for ur response.....
i just go a manual of a ebay seller, the guy is selling gauges which are adaptable.

Below u can see which signal the gauge can handle... !!!

Do u know which signal the camaro pcm is using ? Thanks Achim



Speedo, hall effect sender (logic input, square wave, 12V) 110

Speedo, magnetic sender (analog input, sine wave, 2.1V min.) 111

Speedo, S1 can set to 0 if not working at high speeds 0xx

Speedo, S2 can set to 0 if reading not stable x0x

Tachometer, Ignition coil or “W” terminal (high voltage) 110

Tachometer, magnetic sender (analog input, sine wave, 2.1V min.) 111

Tachometer, multispark tacho output (MSD ignitions, 2.1V min.) 000

Tachometer, S1 can set to 0 if not working in high RPM 0xx

Tachometer, S2 can set to 0 if reading not stable x0x

so far i could check the internet , the signal of the camaro pcm is a

4000 pulse per mile square wave DC signal

so i would say it should fit

here is a link of the parts on ebay

I am installing gauges now..... I will say this. I would not use Speedhut. They are a PIA to get in and work with the LS and they are to much $$$ to have this many issues.
In any case you will need Auto Meter part#'s 2277 and 2268 for adapters for oil and water

If you get a speedo that uses GPS they work with anything....simply needs 12v switched power. No hook up required to the PCM

I used Dakota Digital gauges in my 56 Chevy with an LS swap. Very happy with the instructions, installation and performance. Planning to use them in my Suburban.

ACII, if you want to use the pcm signal post your question to "critter". That's his avatar name, he's terry from lone star dyno. I changed from a 5,000 rpm tach to an 8,000 tach when i did a ls1 nova gauge cluster mod and the 5,000 rpm tach was spastic when i put in the ls. Terry was great to work with and his attention to detail is right on the money. The stock pcm tach signal can be scaled up to a higher voltage level if i remember correctly, but get with terry.

thanks for that advise...i will get in contact with Terry.

I will kee u updated about the installations .-)
