Rev limiter

[Thomas Patterson]

I got the X Cal II the other day and flashed it with the 87 program. I thought this was going to get rid of my rev limiter, or is this something I have to do from the peramiter menu? Also what Oct to run with the high program 92 or 93?:unsure:

i had wayn remove mine when he set mine up but you can adjust it for the program on your pc

Also what Oct to run with the high program 92 or 93?

uummm... :huh::blink::unsure: What Octane rating do you run with your stock or 87 octane setting??

 

[Dallas Starr]

It depends, I think he does a 87 octane performance tune as well as a 91 octane one. Which one did you get? I think this is what you were asking

 

[Thomas Patterson]

He provided two tunes one was 87, self explanatory, the other was a high performance no oct mentioned.

 

[Mark Grumpy]

That explains it. Do you remember what you ordered? 87 reg and 87 high or 87 and 92/93 high? Or something else. Best bet would be to contact the programmer/dealer. Did you get it from Wayne?

Are you confusing the Rev Limiter with the Speed Limiter. They are different and have different functions.



The Rev Limiter only works when the transmission is in Park or Neutral and limits the revs to aout 3000 RPM to avoid engine damage. That's a go thing.



The Speed Limiter will limit the top speed to about 97 MPH. The main purpose is to limit the top speed so as not to exceed the speed rating of the OEM tires. There are also some people with early 2001 Sport Tracs that did not have the speed limiter set and received letters from Ford stating that the transmission output shaft bearings would not tolerate extended periods of driving in excess of 97 MPH. Those vehicles were reprogramed (without the owners consent) whenever they were returned to the dealer for any service.

He may not have included it with the 87 tune and only with the high octane tune...

the high tune is basically for 91 octane and up. If you can get 100 like i can I had a special tune made..
