[kickeralpine]

The one that limits at 4k is an ATX and the other one is an MTX

 

[kickeralpine]

sorry both atx

Does the one that redlines at 7000 RPM have a computer chip in it?

 

[kickeralpine]

just got that car so im not real sure

Open the glove box, push the tabs in on the side, and let the door swing down. You should be able to look in the opening, towards the top and see whether or not there is a chip plugged into the back of the computer.

Do not rev it past 4K in PARK even it it lets you.

If you do, your torque converter won't last very long.

Vrooooom! My car is faster than yours standing still!

I've never understood the fascination people having with revving a car in park or neutral...

i dont like to rev in park its a new car to me and was checking a few things and noticed it went up to 7000 dont really like it doning that thats way i was asking why it was

 

[shoebilly]

Using common sense, the neutral rev limit is 2500 rpm or less.

 

[kickeralpine]

ok easy on the flaming was a question why its doing this its not normal ok. it does not have aftermarket chip in the back of the computer but looks fairly new.

The factory rev limiter for the '94-'95 ATX is 4000 RPMs in park/neutral and 7000 RPMs in drive.

 

[kickeralpine]

well its doing 7000 in park dont now why

well its doing 7000 in park dont now why

If your engine is truly spinning to 7000 RPMs in park or neutral, then you either a) have an aftermarket chip connected to your computer (most likely), or b) have something amiss with your setup somewhere.

ok i looked at the back of the computer and i dont see no chip out the back like somone said it would be and is spinning up to 7000 in park my other 94 atx doesnt do this also seems to lack power runs nice but my other car will **** it

Keep your foot off the peddle in park.

If it's not chipped and it's revving to 7k in Park and Neutral, you may have a bad MLP sensor, aka Neutral Safety Switch.
