Welcome to Cadillac forums!! :welcome: :wave:

Sorry I can't help you with your speed limiter, but there may be people here who can.

Try this board:
Pretty fast ya?
You gotta get better tires to safely go above that....not to mention its very illegal :D

Kulika, check the "northstar at high speed" thread on Cadillac Seville/Cadillac Eldorado Forum above here. I had the same question on my 98 Eldo which is not an ETC. MtFlight and others relate what was mentioned higher speed tires, but also say that OBDII (after 96) cannot be "ungoverned" without major changes to the PCM..........118 and the fuel shut-off screen lights up on mine, too. Good luck and welcome!
