I'm asking this for a friend...Have you guys heard anything good/bad abou the ADS Superchip for a 350 TPI? thanks

I used the street chip on my 85 TA and gained .2 tenths and like 2 mph so I liked it.

i personally wouldn't waste my $. The only thing it really does it change the spark/timing stuff during WOT

i agree with fly89gta. i had one in my iroc and i didnt notice any difference from the stock chip. i am using the stock chip in my iroc now. not worth the money.

I haven't put mine in yet, but if it's good for .2 off your ET, it's worth it IMO.

I have heard good things about ADS and JET but for the love of *** tell him to stay away from hypertech chips. I have a stage 2 hypertech and a friend of mine that did my custom chip looked into the programing of the hypertech. There was a rais of 2* timing and the fan setting. At least it came with the car and I didnt' pay for it.

I don't know from personal experience, but I have usually heard nothing but bad things about Hypertech as well.

ADS....NNNNOOOOOOOOOOOOOOOOOOOOOOOOOO!

Stay away from that damn chip. I had one in my car and it gave me nothing but problems.
1. Car overheated constantly.
2. Wouldn't keep the timing the same.
3. Would cause the car to just DIE.
4. Got Horrible gas milage.
5. Would trip codes constantly.
After removing it and putting the Factory chip back in, the car ran like I just put a new motor in it. Also, never had the problems above ever again.

Take it from a few of us who have beenin your position, just get into PROM burning or get one custom burned for you. It will be cheaper and you'll be much happier with the results.

I've read the ADS chip. Only the WOT spark curves are modified, nothing else. Use the $100 towards a prom burning setup, you'll be happier.

if you look here on thirdgen .org you have a article on test with chips made on a 305tpi wich shows good performance data, I just wonder is that article just crap or??? I personaly have a performance recource chip in my 350 and i noticed i differance!

I bought an ADS Superchip (piggyback version) for my car way back in the early/mid 90s. Frankly, I never noticed much other than the TC seemed to lock a little later.

When I got into eprom burning, I checked my ADS Superchip and the only changes I found in mine were:

1) A little extra spark in the 2,000-4,400 rpm range and only from 95 and over MAP Kpa (i.e. WOT and only at elevation levels < 1,200 feet)

2) More fuel from 2,800+ rpm from 95 and over MAP Kpa (WOT at elevation < 1,200 ft)

3) Locked the TCC at 42 MPH instead of the stock 38 MPH.

And that's all. I did a binary compare and that was the only differences between the ADS Superchip and the stock AUJP for 90-92 SD F-body cars.

Now the bad news, who ever did the spark tables was on drugs. The spark (when you graph it with TunerCat) had "waves" like and ocean. Peaks and valleys all over the place. It is the WORST Spark Curve I have seen from any BIN (aftermarket or other wise).

The rate and speed you "bring on full advance" is crucial if you want to get max power and minimize knock. After a lot of testing and monitoring, I found a spark curve that works very nicely in getting to full advance quickly without causing detonation. The difference in performance can defintiely be felt and measured.

The ONLY use I had for my ADS Supechip, was to pull the eprom and replace it with a Flash Prom and using it for prom burning, and saving my stock Memcal as my "backup".

Have you read other aftermarket chips? Like Hypertech, Jet and performance resource? If you have could you give me some info like you did on the ADS. The info was very insightful and I'd like to know more about the other brands.
