rev limiter
Does the Superchip bypass the factory set rev limiter? Just wondering as I wait for my Superchip that is on order.
By the way, I know this has been said many times here, Dealing with Mike T. has been a breath of fresh air. I deal with a lot of mail order products, and to actually talk with someone who knows their product the way he does is really rare these days. Hats off to Mike T.

Here, here; I second the Mike/Superchip praise. I wish he could be cloned, and placed at every service oriented business that I use.

Hi Adam-K,
No, the Superchip does not "bypass" the factory rev limiter. Removing a rev limiter can be a very dangerous thing, so we do not do that.
We do remove the top speed limiter whenever possible, but the top speed limiter is a completely different and separate function from a rev limiter.
Now on some vehicles we will *raise* the rev limiter if we can get more performance and still not exceed the design limitations of a particular engine. On V-8 F-150's, the rev limiter is generally raised a couple hundred rpm, just to give you an idea.
But "by-passing", or otherwise completely eliminating a rev limiter is not a good idea generally speaking, so we do not do that.
Sometimes people think that the rev limiter is the same thing as the top speed limiter, that's a fairly common assumption, but they are 2 different functions.
A top speed limiter will work in any gear that allows enough vehicle speed to exceed the factory limiter.
Rev limiters generally come in 2 varieties from the automaker; the absolute rev limiter, and then a "no-load" rev limiter. The absolute rev limiter controls the highest rpm the engine is allowed to run under normal circumstances. The "no-load" rev limiter kicks in anytime there is no load on the engine, such as reving it up in neutral or Park (or with the clutch in on a manual), or if you're spinning the wheels very hard. Typical no-load rev limiters for many Fords have been in the 4500 rpm range, though this will vary depending on which engine/vehicle.
And of course thank very much for your kind words, gentlemen.

Thanks for the info mike. I was sure of the functions of the limiters, but I guess my question was a little vauge. Obviously, I wouldnt want to turn my little 4.2 harder than I need to. Another question if you dont mind. I understand that there is a learning curve for the computer after I install the Superchip. Does the transmission reprogramming take effect immediately or is this included in the learning curve? Do you reccommend a switch to synthetic trans fluid BEFORE the chip is installed or does it not make a difference? Thanks again!

Hi Adam-k,
We like to see synthetic transmission fluid installed regardless, it's always beneficial, and you can do that at anytime, as long as you don't have any transmission fluid leaks, of course.
The changes to the automatic transmission programming take effect immediately.
