I know the manual computers were different than ours(91 auto gsx), which version of the manual computer should i get to make sure it works with my car? Its so i can run 550's or larger injectors better w/o going to DSMlink or a standalone.... yet

You'd want to find a 1G M/T ECU with EPROM. The EPROM would allow you to swap in different chips to compensate for fuel cut, injectors, etc..

The chips are fairly cheap. These chips do not "tune" your car. It just gives you many features and allows you to get basic maps for different injectors. You'd still need some type of piggyback. Just read through their site.

You would be better off getting a SAFC or a 2.xx chip for your MAFT setup if you dont already have one.
There is really no diffrence between the A/T and M/T ECU other then ones made for 390's and ones made for 450 cc injectors.
The A/T ECU doesn pull timing when the trans shift though. By putting in a M/T ECU, you car will no longer pull timing on shifts which is hard on the A/T trans unless you have a shift kit installed.
The EPROM ECU isnt really a good way to go for price versa's affect on the A/T... Most of the features of the upgraded eprom chip do not do anything for an A/T car anyway. They are more geared towards M/T cars.
You will spend like $200 to $250 for JUST the 1G EPROM ECU and you wont know what your getting until its in your hands. Could have leaking caps.
Best case the caps having leaked but you will still mostlikely wanna have them replaced which runs about $50 to $100 dollars depending whom you send it to. Then a socket install can run upto $100 dollars also. Some shops do give discounts if you get both done at the same time. I know one shop that charges $80 dollars both both the cap and socket install if done at the time time.
Then there is the chip.. The chip will run like another $115 dollars ontop of the ECU cost and socket cost. Altho you can go with a lower stage but its not much cheaper.
I'm sure you see where I'm going with this. Unless you need all the features this ECU will provide, just keep the ECU you have and get an AFC unit.
Altho the new MAFT 2.xx chip is suppose to be just as good as an AFC and an AFC isnt needed.
Altho I still run a MAFT 2.01 and an AFC2 along with a M/T non-eprom ECU and a 550CC injectors.
I do have a full stage 3 eprom ECU out of a 92 tsi m/t turbo though but I think I'm going to sell it. Only feature I got any useage out of was the stock boost to knock gauge ;P
Sorry for my long message. If anyone thinks any of this info is wrong, feel free to speak up.
On a side note even with this eprom ECU setup we spoke of you still need a tuning device such as a MAFT v2.xx or a AFC.
Eproms are really a waste of money on A/T's in my opinion.

DSMLink is worth it's weight in gold to me 
I too, am kind of curious about swapping out my 98 gst automatic ECU with one from a manual tranny. In hopes of putting in the larger 450 injectors without having todo any special tuning(I think).... I am sure someone has done this. Lets hear your expertise on it

You don't have to swap ECU in the 2Gts the AT and MT are all the same. Same injectors, same cams, etc... The only benefit a 2G ECU swap would have is if you went with a 95 ECU with EPROM.

well hmm I have 450cc injectors in my glove box and was curious if I could just install them and go..
or would I need an SAFC to tune them?? I still have the auto ECU.
when you guys say MAFT is that the MAF Translator or something completely and utterly different?

I'm getting a ported 14B, ported 2g exhaust manifold, Ported 2g O2 housing this week. And after reading kdog's post I think I am going to stick with my stock A/T ECU.
I'll save up money and get S-AFC II and 550cc injectors. But Along with those I'll probably need a new fuel pump, a rewire kit, and a FPR .... correct?
Also, how much difference would it make if I replace the A/T cams with 93/94 M/T cams? I've read somewhere that 93/94 M/T cams are the most agressive. But I would wanna wait on them till I get more money unless they result in huge hp gains ...
I looked at the EPROM chips sold by some vendors and really I don't see any useful features that I can't do without in my A/T ECU.

Yup, I seriously can't stress enough how important an FPR is when you upgrade your fuel pump. This will give you the most efficient tuning capabilities.2_blue said:
All 1G MT turbo cams are the same, and yes they are the most aggressive out of all the stock DSM cams. They are definitely worth the upgrade from what test results I've seen. There are plenty of guys making an abundance of power on them. And for the price you could pick them up for, it is an oppurtunity not to turn down.2_blue said:
I know I gave my set up to Billios. If hes posts, he'll tell ya what his gains were.

bringing this thread back from the dead. My dilema:
I have 450's, 14b and MT cams in my car right now (91 auto TSI). The thing is with my auto ECU i am hitting some pretty severe fuel cut in the upper RPM's and am trying to weigh my options. So there is no way for me to just throw in a 91 MT ECU into my car? What is the dfference between the two? I am considering getting an afc but how would that fix my fuel cut problems? Thanks

yes i understand that aspect of it and the car does run alright but I can not run it to its full potential (upper RPMS it knocks but other then that its fine). My question is will I be able to interchange the ECUs without anything else? Do i NEED an eprom when i use the MT in my AT?
I don't believe you NEED an EPROM ECU ... but its always nice to have it. Read the last post of the following thread:

You do not need EPROM to swap ECUs. EPROM is only if you want to put flashable chips in your car.
