Hey guys,

Quick question do both of these functions work on a 1987 GTA? I want to burn a chip for mate who is getting his car transported and does not want anyone doing burnouts in it while it is on its way.


Can I lower the REV limiter to 1500rpm and speed to 20mph on the chip and it will work.

I would try it on my car but I don't have the time and also I need to order the adaptor ASAP for him.

Any advice or confirmation would be a great help.

 

Also anyone know the stock code for the 87 GTA 350 BIN? I don't want to install anything else other then the stock table since I have never looked at the 6E version and don't want to get into it yet. I just want to help my mate out with the limiters. The only reason why I want to locate the stock BIN file online is so that the guy selling the card does not have to pull the chip and send it to me so I can access it.

I have read that I can use the AUJM 6E Bin and do some changes for the fan. But I need to get it right the 1st time since I will be sending the chip to my mate without any testing.

SO it might be easier to get the stock 87 GTA 350 bin. Anyone have any part numbers?

 

I cant help on the '87 GTA prom code, but you can use the $6E code if you also disable the VATS controls. The stock rev limiter is 10000 rpms, basically useless, and you can lower it easily. The speed limiter is 110 in the low-perf cars and 255 in the high-perf cars.

 

I am just not sure if the rev limiter works like it should? So basically if i lower it to 2000rpm it will not go above 2k right? I have never tested it and I know some ffunctions don't work like they should on the chip sometimes.

 

Thats the idea...

 

Well yeah I know but the reason why I am asking a stupid question like this is with VATS it don't make any difference if you don't have VATS in car and tick the little tick to enable VATS as it does not affect he starting in anyway. Then I heard some other person have the speedlimiter at 125mph and the speed was cutting out at 110. So all I basically was asking if anyone has tested the rev limiter to see if it actuall does what it is programmed to.

 

I've done the same settings in my SD setup ($8D) and it did exactly as I wanted.
2000 RPM or 15 MPH and the fuel would just choke.
Worked nice.
I had forgotten about it several times and didn't switch my "running" bin back on and when I tryied to jump into traffic it would make you think twice.
If you would try to really get on it, it would stall unless you let up quickly.

Not sure what the addresses are for the $6E stuff but I would say set them conservative to 2500 and 35 mph.
That way any scale problems would still allow the car to be moved but not beat on.
VATS would make the car immoble and not be able to do anything.
I don't belive that was your intent.

 

JP86SS,

Thanks for the confirmation. With the VATS I was only saying an experience that I found with it. I enabled VATS in my NON VATS car and wanted to see if it would stop the car from starting. In my case it did not stop the car from starting.

Maybe I stuffed something up or did not load the new BIN into ostrich maybe I forgot and only changed it on PC but, I am pretty sure I did do it correctly. Even though I had VATS enabled the car would start. Keeping in mind my car does not have VATS.

That's all. I just wanted to make sure the rev and speed limits work as they should.

Thanks,
MIke

 

Mine was SD ($8D), Different code so its not 100% on your app.
I'm Assuming it would have the same effect though.
Would like to know if anyone else has tried it on a MAF car.
If the code is not present for a non VATS application then the injectors won't be cut off by it. Probably why it didn't do anything.
If you want the car to totally not start/run, just remove the memcal.
It ain't going now where without that.

 

Funny you say that.

I'll just go over what I was saying so it is clear. I converted to 730ECM from 165 ECM.

If I left the VATS ticked in the BIN ( i used a stock 1992 305 Bin) the car would start. When I was thinking that the car would not start because the 730 ECM is waiting for the signal from the VATS but it had no difference the car started.

I even tried removing the memcal and starting the car it started but I am not sure how it would run as I did not want to run it. I just wanted to check if the car would start at all. and it did.

 

interesting.
I know mine won't start with AUJP if VATS is checked.
(bit me a couple times now)

 

I will have to test it again to be double sure.

 

does seem odd. my 88 would not start with vats selected.
keep in mind it is the same ecm box and board used from 86-89 so if the code is is telling it to look for the start signal then it is looking for the signal on XX pin to the ecm and it is not there then well... no start


the only other thing I have noticed is for some reason when burning chips some stuff seems not work the first try or two. almost acts like the proms are not fully blank dispite the blank check. far fetched but, is it any way remotely possiable to have a hard burn in a chip? (like when you have a burned image on a monitor?)

 

There's two bits marked vats in 8D. Unchecking the one, will result in zero fuel. Never checked too see what happens if you do just the other one.
Lot's of people have have forgot to uncheck vats...more than once. It works.
Usually, when leaving vats checked and the car still starts. Means your in limp mode. If you ever look at the vats code in a hac. It's very clear.
If the vats test is failed, zero for the PW is stored in the register that controls the injector driver. Same thing happens for the rpm and speed limiters.
