I've been looking over the tuning section of shoforum and i cant seem to find what i am looking for. I just ordered a tweecer. can someone point me in the right direction where to start my learning? i have a d4u1 and a bone stock atx.

Because you can reprogram shifts and other aspects for smoothing shifting and better fuel economy, among other possibilities.

Perhaps this is in the wrong forum considering the subject matter. Though the people who truly know twEECers will be lurking in here.

Datalogging isnt too necessary with a stock motor. Play with the shift points and figure out what you like.

Eectuning.org will help tremendously.

i recommend talking to a guy 1993SHOmtx or i have that backwards i forget now but he put it on his old atx and the shifts were freaking beautiful he knows more on the atx then i do.

for the most part read the manual and just play around with stuff which its nice on a stock car because your not really gonna hurt anything.

i recommend fuel tables and spark tables the most thats where you will find your power

Really?...Rethink that advise. You can hurt the trans. If you know anything about tuning shifts, tv pressures, engine load, upshift and downshift schedules you CAN mess something up.

There is nothing to minimal to be had from tuning a stock SHO. There are two table for spark on an atx unlike the mtx. The atx uses a much more complicated spark strategy. The best tuning advantage on even a stock atx would be disabling torque management. That is the key.

i relise that i didnt recommend messing around with shift points and such i actually said about talking to someone about it...

i also said i didnt mess with atx stuff im only basing my info on what i did with mtx stuff.
no matter what messing with spark and fuel is where the power is at... i really dont see how what i said was wrong... sorry dude but please dont criticising what i said you come off very rude

now that i think about it from what i remember messing around with diesel autos that playing with tq management on a unbuilt auto is a no no and will cause a high bill in trans rebuild..

your telling me that he shouldnt be messing with auto setting for fear of damaging the trans yet your saying to remove tq management which is what controls how the power is put threw the trans for shifts and such, so basicly the computer will ease the power in able to keep the trans alive in a shift. and your saying to make it full power on shift which will probley slip the clutch packs and cause excessive heat which as i recall is these autos cant flow and keep cool as it is.

yes sir welding 101.. slip the clutch packs on the friction discs till they become one...



also these cars run super rich from the factory and your saying there is no power in that.. it will add power and yet give better mpg..

playing with the spark also will help since the spark map isnt perfect from factory..

also the secondaries can be moved some...

since you will have the tuner get a maf.. there is maps for the 80mm so go ahead and grab that up in the boneyard...

i wish you the best in learning how to use the tweecer it has a learning curve.
dont be afraid to ask questions with any luck can get a thread started and make it a stick for others to learn from

From personal experience, I promise you there is something to gain on a stock SHO. The stock PCM is written to account for a wide variety of SHOs that were a mass-produced item. Correcting the tune for the specific car can make a very noticeable increase in performance. To add to that, if you do plan on keeping the car stock, paying $500+ for tuning or a tuning device isn't very cost effective. I don't know what is available now, but a $200 LPM would be the better route. Learning how to tune a stock car is suggested over adding boost and then learning.

The MTX has quite a few spark tables, however, we don't have to worry about controlling the transmission with the PCM.

^Thank you.

your telling me that he shouldnt be messing with auto setting for fear of damaging the trans yet your saying to remove tq management which is what controls how the power is put threw the trans for shifts and such, so basicly the computer will ease the power in able to keep the trans alive in a shift. and your saying to make it full power on shift which will probley slip the clutch packs and cause excessive heat which as i recall is these autos cant flow and keep cool as it is.

TQ management applies to timing and fuel based on load. TQ management usually only comes into play when the atx is modded. I am messing with it because I am far from stock in every category. If he is going to mod his ATX and is looking for true performance he will run into bogging off the line. TQ management does not necessarily pertain to shifting events, but to timing and fuel and the control thereof. Disabling this on a stock ATX is not going to blow the trans up in my opinion. Disabling it with slicks would be fun to see the 1/4 time.

The ATX has more complex spark strategy than the MTX does. The best he can do is leave it alone except for bypassing the borderline spark table (there is a way) and using just the base spark table. That makes life a little easier for tuning in the future. As referenced above, a stock ATX will not benefit from any fuel, timing, maf, etc. adjustments. Stick with minor trans changes.

My response may have seemed a little harsh, I apologize. But telling someone to just mess around with it, your not going to mess up anything, is pretty bad advise. He could mess something up if he desides to cross an upshift and a downshift, or bumps the trans pressure too much. Things like that can cause permanent damage. That is where I got my reaction from.

and your saying to make it full power on shift which will probley slip the clutch packs and cause excessive heat which as i recall is these autos cant flow and keep cool as it is.

The problem is usually heat. The best advise for him would be tranny hard line replacement, endtank bypass, and high flow trans fittings with a nice cooler. The faster the shift the less slip.

The torque management is not for stock transmissions. He is just saying that is the trick to the atx. When you get to a certain hp, the pcm wont let you put all that power down. Im talking 0 deg timing while launching.

see thats much better seems to be a better response this time... no one is saying no your wrong because your ******** or something of the such..

no one was really wrong but the statements were not completed is all.

i have to agree with jason tho its pointless to have such a high dollar tuner for a stock car unless there is big plans in the future which this would make a great learning experience then before hand.

i think the best way to tune a atx is build it first, since they cant even survive stock do as whiteguy mentioned with making it flow better. even a aux pump might be best from what i heard from somedude before in the past flow is the problem..

with enough flow the cooling can be kept in check.

like i said talk to 1993mtxsho his atx was a beast i know hes got some info on the matter. after one ride in his car i wanted to get a auto just because i liked how it shifted

Out in front!
If/when someone figures out the ATX's completely, We'll see 1/4mile times drop significantly.

So you all hurry so I can use one of thees boat anchors in my yard .
