where can i get the (xcal 2 /tune) and what does it do exactly.please let me know.

You know we have a branch pretty much dedicated to this unit right in the PCM Tuning? This is by far the most popular unit. Tons of good info there.

You can buy it on www.brenspeed.com. Brent has ran group buys here before. Theres some info on his website about what it does as well if you want the short version instead of not reading the loads of info everyone has posted about it here.

I got mine from Brenspeed ... good price and good customer service!

I can tell from your post that tuning is not something for you. It takes a lot of knowledge about cars. Most experienced people only deal with smaller things and fuel (Nothing to do with timing etc.)

I would say you only really need to get an xcal2 if you are doing some serious modifications, 3L, Turbo, Super, NO2. If those are some things you have done or plan to do the xcal2 will be necessary to alter the PCM to accomodate those modifications. At that point I would turn it over to someone with much more experience, say Warmonger, or an SCT dealer to tune for you.

As far was what it does...it plugs right into the OBDII port under the dash and flashes the cars computer. So when you are working with a tuner, they will send you a tune, you transfer that tune to the xcal2 and then use the xcal2 to load it onto the car. The xcal2 also has the ability to data log, which, sorry if you already know this, means it will monitor and record the output of user specified vehicle sensors. Tuners, will then use that data to make adjustments and fine tune your vehicle.

Even someone that doesnt know anything about tuning can figure out a X-cal 2, since they arent doing the tuning. Just plug it in and upload the tune. Now the PRP on the other hand...

Sorry, my bad.

I don't quite agree with this.

The xcal and tune is beneficial for someone with all the bolt on mods. Meaning complete exhaust, open filter, opt. TB...getting a tune will def. give ya some extra power. Not to menton in ATX you can have your shift points changed, and in a MTX you can have your fuel shut-off or rev limiter changed.

Yeah, I would place the FULL menu of bolts ons in the catagory of serious modifications. The xcal2, in my opinion, would be a waste of money for someone with simple stuff like intake and removed resonator. Yeah, it would be an improvement over stock tune, shoot, even without ANY mods you could improve upon the stock tune with it.

I don't know if I will help with the controversy but...

A tune for our cars really only does a couple of things.

1. it changes basic settings like rpm, turns on/off wanted/unwanted stuff like downstream o2s and egr, etc.

1a. It allows changing things that are simple swap-in, like injectors, so not much differnt than what I said in point #1

2. It adjusts the air fuel ratio of the engine through the following:
----Dials in the MAF calibration better so it reads accurately (and many don't even stock)
----Adjusts the basefuel tables to command the correct A/F ratio once the MAF is dialed in

3. Adjust timing and/or IMRC related timing and functions


So you only have control over the engine timing, sensors and switches. Everything else is NOT under control. So lets say you had a great dyno tune on a fully stock 2.5L where all they did was clean up the air fuel and maybe played with the timing,. Then you buy a set of headers and install them and come to me asking for a tune to compensate for them.
First thing I'd do is tell you that NO retuning is necessary.
Because all headers/exhaust mods will do is free up the exhaust and maybe allow better cylinder filling because the exhaust is able to come out easier.
The ONLY possible consequence of this is an increase in airflow on the intake side right? So that means that the MAF will read the increase of air and the PCM will add fuel automatically. Simple, like it is supposed to work.

So will tell you that ANY intake/exhaust mod you do that does not change the MAF/INJ/or other hardwired parts to the pcm will not require a new tune. ONLY if you have increased your incoming air capacity beyond the stock MAFs capability to measure, or beyond the stock fuel systems capability to provide fuel would you need a new tune, and at that point you need new hardware and then a tune to dial it all in.

So I say to you that a tune is just as relevant on a basic engine if it is done right, but then you no longer need to keep redoing IF it was done right the first time. Now if you had a nice tune and popped in a 3L(but kept same maf/inj), then it would still work but on the other hand there are things that can/should be done in the tune to help the 3L run better.

However, a stock SVT pcm/inj/maf or basically the stock SVT injection system is perfectly capable of running a 3L swap. Period.
