I have purchase a chip from ebay to override the governor/restrictor. I am hesitant to put the chip in. Can anyone give me some advice? Here is the link to the product i have.

No offense man, but you just got ripped off.

That chip is going to do nothing for you at all. Just by reading through the item description its obvious its a quack.

Live and Learn

 

didnt realize our cars had a governor on them. i also didnt realize firebirds were made by GMC. sorry dude.

 

ya governor cuts in a 180

 

governor does nothing to regulate speed in thirdgens. it is the limiter in the programming that does it. plus, the firebirds and camaros used the same motors so why wouldn't it work in camaros? plus, the later firebirds with the LT1 and LS1 used different programming than the thirdgens do as well as different ecms. so how is it this chip fits all birds '88-2000?

i agree, i think you got ripped off.

 

Well, there goes $60 for nothing... lol

May as well have just burnt that money or bought some beer, at least if you bought some beer you would have gotten something out of that money!

Actually beer is a really good deal, its like a 2 for 1 deal. You get drunk AND a hangover

 

Your car is "Speed Density" made from 1990-1992. You need a specific memcal for your particular model, engine, transmission & gear ratio and SOMETIMES your specific year (though sometimes a 1990 will work in a 91 or 92) depending on the model.

Simplest thing to do, find some fairly local that has the eprom burning equipment and get them to reprogram your memcal for you. There is no "simple" eprom you can plug it. You need either a memcal or "adapter" with a flash-prom...either way they are not "just a couple of bucks". So the cheapest thing is to find someone to reprogram your memcal (or send it to someone....and wait until it's returned....but your car is undriveable in the meantime.

 

lol.. beer would of been a better expense for sure.

 

I am going to email them and see what answer they come up with.

 

This is the response from the company:




Hello,
The Accelerator connects to the Coolant Temperature Sensor . It will not remove or overide any governors or limiters, but it will help you reach those speeds faster.
Ebay rules specify that we have to list for specific models.
Thanks again!

well since it actually says nothing about a govener in the auction, it looks like they have done thier due dilligance. from what i can see in his feedback, ppl only get a 5hp gain and thats it. seems also that the seller is into bribing the buyer to leave good feedback. you know i have to say that this is a lesson for you, READ EVERY EBAY AUCTION AND EBAY SELLERS FEEDBACK BEFORE PURCHASE. there are plenty of idiots out there that wanna take advantage of us.

let me sum up "gadgets100" feedback for you. most ppl left positive, but most ppl only said "fast shipping and good instructions", they never said anything about the quality itself (leading me to believe they were bribed). a few left positive feedback with results of over 20hp gains dyno'd and were pleased with shipping and quality. every person who was neutral said that the part didnt do what they wanted or that they were bribed to say good things, some said that they couldnt tell hp gains even tho it was installed properly. and EVERY single negative responce said that it made the engine worse or didnt work at all dyno'd and they tried to bribe the buyer for a good feedback.

thats bad feedback...he should be removed from EBAY as a seller.

all you can do now is pay for it and leave bad feedback, you get what you paid for, and not reading and doing your due dilligance allowed him the win.

 

Say you want a mutual withdrawl from the auction. If you give them bad feedback they will just give you bad feedback.

Since it is going to happen might as well get the bad feedback you have coming and keep $60.

unless you have it in hand... in that case sell the sucker to a sucker and cut your losses.

 

Ya, my fault there for lack of research, does anyone know a good governor override chip that doesn't involve soldering?

 

the VSS is the only thing holding back thirdgens. Not that i would do over 120 or 30 anyways for fear or blowing the engine. You dont get any HP out of it. It just helps you to your grave.

 

Bump

 

what does the vss have to do with it??????? the restriction is in the programming, not the sensor.

 

Just for note, none of these cars have the power to actually go a true 180 without many other mods. Maybe with miles of wind up, but that just leads to catastrophy.

- sorry about your luck, - as was stated, you need to research before clicking that key.....

 

wow that ebay add was like an informercial that i had to scroll through

 

http://www.pcmforless.com/index.php?...d=44&Itemid=40

that will get rid of the speed limiter

 

you got it mixed up in Canada we run km/h not mp/h so he says 180km/h is 110mph and a stock 92 305 tpi can easly do more than 120mph stock . I have all stock internals in my 305 TPI and i've done 250-260 km/h 155mph
so some 1 said i will blow my motor if i do more than 120-130 mph how is that i and doing 145mph at 3900rpm.

 

umm where do you think the programming gets it's input from? cut out the VSS and you cut out the programming's knowledge of what speed you are going negating speed limiting.

 

instead of cutting out the vss, which can be used for other purposes, why not just adjust the max speed in the programming. that would be much simpler. as i said, the vss has nothing to do with it. it is the programming.

 

And you trigger an SES code and make your engine run like crap. Also, the VSS is required for the speedo to work on a SD car.

The VSS is a required sensor for the ECM. Overriding/disconnecting it is not an option. The only fix, is to get a chip with the "speed limit" set up to the maximum 255 mph.

 

$5 (a switch, some wire, and some connectors) and a half hour, and you can get rid of the speed limiter easily...

Speed Limiter bypass

I developed this, shared it with all, and Bradley did the write-up on it, when we first founded TGO.

I still believe it would work on TPI cars as well, as it really only interrupts the signal to the ECM, causing thhe speed limiter to kick in. I just haven't had any reason to try it on a TPI car.

 

I think they meant they wouldnt take the chance with a 20+ year old car.

 

Thanks guys.

 

so? did you get the part yet or not?

 

Were thrid gen Firebirds goverened? I know the 4th gens were. Or was it just the 5.0's? What about Camaro's?

There's also a paragraph that's says a 30 money back guarantee. You may be able to get your money back. I wouldn't leave feedback until you find out if they'll give you your money back.

 

I doubt the early carb'd ones were...dunno hohw they would even govern a carb'd car.

Both my TBI cars were, haven't tried in my GTA TPI...nor will I, unless I wanna die.

Dunno when the governer started (in the year), but I believe the 1LE (police package) cars had no governer.

 

the governer has nothing to do with it. it controls the shift points. the programming is what controls the max speed.

 

The tranny governer and the electronic speed "governer", are two totally different things. Governor is just the generic name used for the speed limiter.

We are not discussing the tranny governor.

 

My 83 t/a will go 130, maybe 135 if im lucky. The reason is no horsepower not some limiter. Also, my friend has a 89 iroc-z w/350 and it goes bout 155 to 160ish.(ran out of road) We use gps units to acquire our top speed. So carb no limiter, tbi no limiter, tpi no limiter. Though ive seen a 92 rs w/305-auto bounce off 135mph(engine cuts in and out)

ok so I have a 92 z28 305tpi
which do i put the switch on to get rid of this damb thing?
114mph on the nose everytime and scary as **** when it happens with bucking and other scariness

im tired of freakin civics passin me on I95 goin to the races WTF

so for an older ecm it says use A10
but i have a 7730 so whch one do I use?
BB10 or BB11

if its even possible without chip....
ugh numbers and letters help please help lol
thanks guys and gals
-ken

 

no one?

 

Mine was a 92 TBI. I haven't looked into a TPI one.

Don't take my word as 100% correct, but it looks like BB10 to me.

 

does urs have a 7730?

do you thiknk i need the switch from the tranny or the speedometer?

if i do it to the tranny wont it mess with the shift points?

 

Well, when I did it to the 92, it was a T5. Besides, our 700R4s aren't electronically controled. The shift points are all internal to the tranny.

Dunno which ECM I had on the TBI or I have on my TPI now.

 

If you disable/limit the signal to the ECM from the VSS on an automatic car, it can cause the Torque Convertor to not lock. The tranny cooler only works when the TC is locked so having it "unlocked" can cause pre-mature death to your tranny. So I would NOT do this with an automatic car under any circumstance.

The correct fix is to change the setting inside the eprom. Using "gadgets" to trick the VSS can result in other problems. Such as, if your car is 1989 or later, it has an electronic speedo and without the proper signal from the VSS, the speedo won't work properly.

 

1LE was not a police package...that was a performance package...no ac fog light delete rear disk brakes baffled gas tank and such...

B4C was the police package.

 

How so? The 700R4 isn't electronically controlled by the ECM. It should has nothing to do with the TC lockup, or the cooler. Everything in a 700R4 is MECHANICALLY controlled.

 

You are correct that the tranny itself isn't controlled by the ECM. But the locking of the torque convertor is most definitely controlled by the ECM. The MAF '165 ECM controls the TC by pin A7 and the SD '730 ECM controls the TC by pin GF6. It is line 422 Tan/Black on both ECMs.

Please review a wiring diagram if you don't believe me. But I assure you, the ECM on both MAF & SD cars controls the locking of the TC.

If the TC doesn't lockup, the excess slippage will generate excess heat and worst, GM stupidly designed the transmission so fluid only flows through the oil cooler when the TC is locked. This will result in shortening the tranny's life significantly as heat is the biggest enemy of the 4L60/700R4 tranny.

 

Interesting...I assume there is an electonic valve in the tranny, that controls thhe fluid movement, into and out of the TC?

On a tranny note...What keeps it from going in to OD, at WOT? C18? Can that be overidden? I think thhe Corvettes didn't have that happen...

 

TCC Solenoid. There's a 4 pin plug on the trans, 3 wires connect there.
As for the OD at WOT, there's a valve in the trans that can be changed.

 

Madmax is correct on both points. The fix is a valve inside the 4L60/700R4 that needs to be changed. Do a search on the Tranny Board for more information on how to do it. The valve was in the Corvette and the B4C (police option). Also it appears some 1991 and 1992 L98s had the valve installed from the factory.

But, once installed, you will be able to accelerate in WOT in 4th gear.

As for the "fluid flowing" when the TC is only locked, there is a modification you can make so fluid will partically flow when the TC isn't locked. There was discussion on this a few years ago on the DIY Prom Board. Do a search on "TC locking" on the DIY Prom Board and you should be able to find it. Conversely, make a post on the Tranny Board on how to make this modification so tranny fluid will flow to the tranny cooler at all times.

 

wow

yea so um iv been told that i could get my prom changed and change the speed limiter to 255mph instead of 114mph. i think ill just let my buddy do that for a couple of bux

 

I'm jealous of my buddies LS1 3rd gen...

Hook up the laptop, tap a few keys, done! EPROMs are cool. No chip burning, so crawling under the dash, nothing.

I might upgrade my PROM to the EPROM style, one of these days.

 

Yes, the newer PCMs with Flash Memory are nice. Just hook the computer to the ALDL port and voila. However, I also know a couple of guys who had a "hickup" when they were uploading during the flash process and the PCM "locked up" and became unuseable. They had to buy a new PCM.

With our cars, I've swapped the stock eprom to a flash prom in the memcal. The flash prom is far better than the stock eprom. The stock eprom can only be erased a few times (somewhere from 15-50) before they become unuseable. And, each time you need to erase them "a little longer" to make there re-program properly. A flash prom like the AT29C256 can be reprogrammed hundreds (or even thousands) of times and don't require any erasing prior to re-programming. The only problem is finding an AT29C256 as Atmel recently stopped making them

BTW, you may want to try this...when I am in "tuning mode", I just shove the ECM up in the passenger side of the dash and use a couple of sponges to hold snuggly it in place. It makes it really easy to access the ECM yet holds it nicely in the dash (instead of laying on the floor).

 

well the speed limiter was low on specific models only. I belive it was decided on tires rating/rim combo's and what type of power plant combo you had... say a 15" rim on a tbi camaro may have a 120 limit? and a tpi 16" may have the 255 mph limit( = no limit ) in the chip. not sure on the specifics but it was along those lines


so what happened with the part?

 

Yes, that is correct. The speed limiter in the ECM was based on the type of tires originally equiped on the car when these cars were new. (And today, as all cars are now fuel injected, all auto manufacturers limit the speed of their vehicles based on the tires that are originally equiped - and some will even limit the speed lower). Also most now have rev limiters as well.

 

So there would be no limiter on my car? 1985 305 Carb'd.
