Rpm Not Working Need Help

[I_love_my_TSI]

Hey Fellas, I Did A Search But I Cant Seem To Find The Answer. My Brother And I Took Off The Slowboy Intercooler And Pipings On The 99 Gsx Last Night, We Then Installed The Stock Intercooler With Stock Pipings Back On. It Was A Breeze, The car starts up fine, but After The Install His Rpm Gauge Is No Longer Working WTF, Its Just Sits At Zero. I Just Cant Seem To Figure What The Heck Happen.i Have Never Work On The Rpm Gauge Before So Im Not Sure How The Rpm Is Connected To The Motor. What Should I Check For ?

Check your power transistor. Unplug it then plug it up again, check for cracks and cuts. I had the same problem with me rpm gauge. One side of my transistor fried out completely. Matter of fact go to the search bar and type in "No tach sigal" you'll see what i had done to fix my problem happy tuneing.
