CVALYNX Posted March 3, 2008 Report Share Posted March 3, 2008 I recently had my pcm tuned by a local tuning shop and I watched move my top speed limiter to 200mph. When on the dyno topping out third gear it was around 140mph and never shut off. On my way home I wanted to see what it would do and evry time it would shut off at 113mph. is there another sensor in the frt that would limit my speed? Any help on this would be great!

Any help on this would be great! well that sounds like a stock MPH limiter on a stock SS. . . .are you sure he raised it? and WTF do you need it to 200mph for, you will never get there? make sure he didnt put it back to stock after the dyno run Quote Link to comment Share on other sites More sharing options...
CVALYNX Posted March 3, 2008 Author Report Share Posted March 3, 2008 BEFORE HE DID THE TUNE IT WOULD CUT OFF AT 100MPH. I KNOW IT WILL NEVER DO 200 THAT'S JUST WHAT HE SET IT AT SO IT WOULD NOT CUT OFF. BUT NOW IT CUTS OFF AT 113? Quote Link to comment Share on other sites More sharing options...
mean05 Posted March 3, 2008 Report Share Posted March 3, 2008 there are a couple of other tables to look at...there is a fuel cutoff table..check it....also if you want you can go to hptuners and pull one of the modified tables and compare it to yours and see if you missed one of them...or i can email you a file Quote Link to comment Share on other sites More sharing options...
CVALYNX Posted March 3, 2008 Author Report Share Posted March 3, 2008 That could be my problem, before when it got to 100 everything would stay running but it would not accel over 100. now when it cuts off the engine shuts down and it will slow to 105 then start back up Quote Link to comment Share on other sites More sharing options...

2006SilverSS Posted March 3, 2008 Report Share Posted March 3, 2008 why are you YELLING? that is strange my truck went over 100 mph bone stock Really? I'm pretty sure that stock mine topped out at either 112 or 113 which I thought was the norm for these trucks. Quote Link to comment Share on other sites More sharing options...

Turbocoop Posted March 3, 2008 Report Share Posted March 3, 2008 Mine stopped at like 108 with the limiter, but now with a PCMforless tune Ive had it up to 120+ and she had more in her Quote Link to comment Share on other sites More sharing options...
CVALYNX Posted March 5, 2008 Author Report Share Posted March 5, 2008 I took the truck back to the shop today and he found the problem. He changed the limit on the mph side but you also have to change the kilometers per hour setting. Quote Link to comment Share on other sites More sharing options...
Krambo Posted March 5, 2008 Report Share Posted March 5, 2008 I took the truck back to the shop today and he found the problem.
