I have a 95 A4 Z and need to to know which program is better to buy, easier to use..thanks!

 

tunercat is cheap.. thats why i use it. i have never used LT1edit but i hear its a little more user friendly. i dont really see how since tunercat is pretty simple. it really all comes down to how much money you wanna spend for practically the same thing.

 

Each of the two programs has its pluses and minuses. I personally like lt1_edit more because of its interface, but I'd say that's about the only thing I would choose it over Tunercat.

If I were to give a general recommendation to someone, I'd have to say Tunercat just for the outstanding customer support TC provides and for the variety of cars it supports.

 

Is there anywhere i can download a tune for a car similar to mine and jus try thatto start out with? Thanks

 

You mean a stock one? Just send me your VIN number and I'll send the right one to you.

 

Either one requires you to know how the car works, how the sensors relate to each other, yada yada. I use Tunercat for the price, the same end result is achieved.

 

Not looking for a stock one, looking for someone who has a tune for a car similar to mine with the same amount of mods...

 

Like madwold says, each program has plus's and minus's, and one should have a general understanding about how EFI works and what the sensors do and a basic knowledge of automotive fuel and mechanical systems before attempting to tune his car in this manner. One can really screw up an engine or a transmission with a few "simple" key strokes.

One thing I like about Edit is that it makes automatic entries to the shift tables when a new gear ratio is calculated. Tuner Cat in its present release does not do that so one has to manually input the changes. If the gear ratio change is not drastic (going from 3.07 to 3.42) then normally there are no adjustments needed, however if going from say 3.07 to 4.10 gears then shift tables will most likely have to be altered for the transmission to shift properly at WOT.

Some say the user interface is easier with Edit, I guess that depends on personal preference. TC uses either a table or graph format, Edit allows graphical views but no editing of the graph. Is it necessary? Depends on what one wants, either way works I personally prefer tables.

TC offers many more diagnostic switches that can be turned off or on depending on applications, Edit allows only a few. TC can now read and flash in both BIN and LT1 file formats.

TC is unlimited and not locked to one PCM as Edit is, and TC can be used on most all other GM car and truck ECMs other than the OBD1 cars we are most likely talking about now.

Plus the one big factor is cost. TC is about half of the cost of Edit. Both programs require an interface cable to talk to the PCM and download to the PCM. Both products are great so now you have to choose.

 

Looks liek tunercat is what im gonna try...does anyone hve any modified .lt1 or .bin files for my car with similar mods so i can compare and test them out? thanks! Also, freescan will be enough to log and monitor all my sensors, correct?

 

To be honest, a stock program is where you want to start with your car. The stock programming is actually quite good. Just start with that and do your idle and part throttle tuning and then move on to the WOT timing and fueling.

 

For most purposes, your car is stock.

 

yea i guess thats true...hopefully will be adding hooker shorties as soon as the government send me my refund!

 

LT1 Edit is $550, how much does Tunercat go for?

 

$550 is for the OBDII version. $200 is for the expert edition OBDI version. Tunercat is $89

 

Tunercat says OBD II this summer, although I heard spring earlier, soon I hope.
