how do u disable speed limiter

i have a 92 birds with a 305 and TBI unit. i was wonderign what i have to do, to diable my speed limiter.

any help would be sweet


thanks

either disconnect the speed sensor wires(will lose speedo and set a code), or get it changed in the chip

Maybe stuiped question but, 3rd gen's has speed limiters?

ya im pretty sure

TBI cars and V6 cars have limiters in them. I haven't seen a TPI car with a limiter set low enought to slow the car.

Here is a picture of my tuning software with teh speed limiter set to 255,

LOL 255 i need that Hax0r!

You cut the VSS and you also lose cruise control and set a code. Not sure if it does affect the way the ECM does the fuel mix tho. Also I believe 3rd gen TPIs came with speed limiters if the tires were not Z rated.

my 87 iroc had a speed limiter at 130 but when i got the new chip it disabled it

where do i get a chip for my car. and how much are they??

I honestly believe my car wopuld fall apart at 130mph if it can go that fast. At 85ish it starts shaking violently.

how fast do you plan on going? AFAIK, the TBI cars had the speed limiter at 110 MPH

I used to have a 1989 Camaro RS w/ a 2.8, it would shake at 85mph but would stop around 100mph. try balanceing the tires...

I can burn one for you for $50, if I can find another chip lying around. The blank chips used in the TBI cars got quite expesive locally, $28 just for a blank chip.

For comparison, the Flash Chips I use in the TPI cars are larger with more memory and I can get those for $6 a pop.

Can you burn me one that would be the same as a Hypertech, for a 1992 TPI CAmaro Z28 5.0?

Ya, but for your car you need to have an adaptor that looks like this,

The adaptor sells for $61 shipped with 2 blank proms, so for $111
I can do your car as well. I'll do lifetime burns of the chips, all you cover is shipping both ways for the proms which is about $1.25 each way.

if i bought a hypertech chip the adaptor comes with it, right?

No, if you buy the hypertech, it is already in a memcal like your stock one. they just erase a stock memcal and re-program it.
JET chips use an adaptor, which is what I posted a picture of.

I don't have a pin adaptor to reprogram a chip that is still in the memcal, and using the adaptors is much easier especially when using flash chips which can be erased in seconds in the programmer. Chips in the memcal are Eproms which require the use of a UV light prom eraser.

HIGHJACKERS! :alert:

driveshaft also

Check engine and especially tranny mounts. Ask me how I know.

There is a tech article on www.thirdgen.org for a toggle switch disabling the VSS sensor. Or just take the plug out.

Yes but that disables cruise control. However, is that all? Will it screw up the ECM calculations?

Ya, I hate not having cruise control when driving 110+ :D

:lol: That's exactly what I was thinking.

aklim, it doesn't screw anything up, how fast you're going doesn't deal much with the ECM calculations. Fuel tables and stuff are dependent on RPM right? In that case, speed wouldn't matter.

only thing I can think of is the TC not locking up since there is no speed reading.

I have set CC at about 120 once. :D :D

Not sure what would happen if the TC did not lock up but I would imagine your RPM would be higher?

my iroc-z came with a speed limiter at 120 mph.

i noticed when the vss is disconnected and the speedo stops working, the engine revs a couple hundred rpms' higher

It's not a computer controlled transmission though right?

Even the 4L60E in my truck locks the TC when my VSS fails (constantly for some reason....)

What code will be displayed when the VSS in the camaros is disconnected (if any)? I wonder if this is the check engine light I get sometimes when I am driving, but it is never stored.

I don't think the tranny is controlled by the ECM in that the shifting is controlled by hydraulic pressure but I believe the lockup definately is.

here is the setting in the computer for the TC lockup,

http://www.tbichips.com/ Does chips for very cheap, like $35-$45 IIRC...
