I am finishing up my car project and have a harness and cpu from a 2000 firebird. I read somewhere that the newer cpu's seem to be a little faster in closed loop self tuning and other computations. Think it's worth while to get a PCM from an 01 or 02? I have HP tuners so I could move my tune over.. I think I'd have to spring for an additional HP tuners license wouldn't I?
Thanks in advance

All you need to do is load an 01-02 OS to the PCM you have; the hardware is the same.

Really? I read somewhere that the cpu was a little faster in 01,02. Must have just been a software improvement. Thanks for the info.

Are there any tips or tricks to loading the new image? How do I load the entire ecm instead of just the tune? I'm guessing I'd have to load a base 01/02 os, then load my tune on top of it, correct?

Thanks

The whole underlying OS is different. You get a file for an 01-02 and do a WRITE ENTIRE. From that point, you can use compare to copy over your injector constants, timing, and MAF calibration. There will be rampant differences in places such as adaptive idle and others; leave them intact as they are in the NEW OS to begin with. Because the data is handled a little differently (and there are many other variables which we do not have access to) in the later OS, you may have some small tweaks to make, but that is the gist.

Ok, sweet. If someone might have a stock 01 or 02 hpt/bin file (perfer f-body 6-speed)they would be willing to share, please email it to me at my username @ comcast.net
Thanks a bunch!

I have an 01 auto bin. PM me if you want it.

Find someone local with an 01-02, tune their car, charge them and then use that file to tune yours as well. So not only will you not have to come out of pocket for the credits, but you can make a little cash as well.

Or just use the credits and upgrade to an enhanced OS. Then you can use the RTT function as well.

If i just use the credits and upgrated to the rtt enhanced OS, will there be any advantage to laying down the 01/02 OS first? Does the rtt enhanced OS already have all the new tables and best features and speed of the 01/02 os?

There's really no "speed" benefit between the OS's. The 2002 OS has the most features, and the enhanced versions of the previous OS's do not have those same tables. Enhancing a 2000 OS gets rid of secondary VE table, which makes tuning a good bit more convenient, and if you're really looking for every last bit of detailed control you can get out of your existing PCM hardware, then the 2002 OS (12212156) will give you the most. Contrary to popular belief, the 01 and 02 operating systems are different.

Cool, thanks for the input.

The RTT OS doesn't entirely replace the oem OS, correct? It overlays certain features on top of the existing os, correct? If that is the case it sounds like I should load the 02 OS first, then the RTT Enhanced OS.

If the RTT OS does overwrite the oem OS entirely, it would seem that there is no reason to load the 02 OS first..

The enhanced OS is a full rewrite, it would be a waste to do the other first. The Enhanced OSs offers benefits over the 01-02 OS. That's not to say, that some don't still prefer the newer GM OS.

Except for radical or boosted application you'll likely not gain any performance from either OS just easier tuning. The RTT really makes things tuning a lot faster as well.

For the same credits I would just go with the RTT, but personally if you're not building an extreme combo I would just save the money now and work with the 2000 OS. Once you get the hang of things, then check out some upgraded and newer OS tunes. And see for yourself why and how it's different(better).

Thanks. I won't bother loading an 02 OS, if the HPT RTT Enhanced OS will completely overwrite it. I've got a pretty large cam and will enjoy the faster, interactive tuning the RRT OS offers.

JonCR96Z you're not entirely correct. You DO do a write entire when you enhance an OS...but an enhanced 2000 OS is not the same as an enhanced 2002 OS, and there ARE features in the 2002 OS, enhanced and not enhanced, that are not in the 2000 OS.

I've never used RTT on mine...my car is a 2000, running 1 bar speed density enhanced 2002 code, and I find it easier to tune and flash.

A LARGE difference is that because of the Holdens, the 01-02 OS supports PE modification based on IAT, which opens a lot of doors for fueling add-ons. It gives a new element to the IAT modifier. If you understand the implementation, you can add or subtract fuel at WOT via external trigger. There are other differences as well, but this one is attractive...

That's what I said.

Yes, some prefer the newer OS over the Enhanced.

I would still at least try it with the stock OS. Just for some experience.

Download an enhanced tune and a 01-02 tune and compare them.

Cool, when I exchange my serial hptuners interface for the usb unit I'll upgrade the os. My license is for all 2000 fbodies. I should be able to do a "write entire" with an 02 os using my existing license/credits shouldn't I. The cpu is unchnaged so I don't think I should have to buy a license for the 02 model year. Is this correct?

Frost

iTrader: (45)

Unfortunately not.

JonCR96Z

iTrader: (33)

Yep, you have to have a license for the tune and the PCM that it's going in.

FDLS6

iTrader: (4)

That's a bummer... I have to have a license for my 2000, the 2002 file that I'm going to load, then the RTT os? Expensive.

JonCR96Z

To have a newer enhanced OS, yes it will get expensive. I still say that you will be fine with just what you have. Unless you are planning on changing stuff all the time, running in open loop or adding power adders.
