twEECer or SCT???

If you know a lot about how the computer works or you feel like learning a lot, go with the tweecer. Its got a pretty steep learning curve. Or for simplicity, just get an SCT chip tuned.

The TwEECer works well and includes datalogging, but you'd need a wideband with it to do it right. There is a fairly steep learning curve, but a lot of people here are really helpful.

I think you were referring to the Pro Racer Package from SCT, not the Xcal 2 - because the Xcal 2 is only for EEC V and above. The Pro Racer package includes a chip, a burner and software for one vehicle - additional vehicle databases are availabale though. The Pro Racer package doesn't datalog and like the TwEECer you need a wideband - and you need one that'll also log a few other things like MAF voltage and RPM. It also has a steep learning curve because it's essentially dealer tuning software, but they include parameter descriptions and you get a base 'starter' file. There is also good support for it - we even sell a Pro Racer Training video that outlines step-by-step how to tune a car properly. Even if you decided on a TwEEcer, the video would give you the basics because some of the parameters are similar.

The TwEECer, as far as I know is only available from one source, but you can get good deals on used ones. Be careful price shopping on Pro Racer Packages - I have dealt with people that have had bad experiences in not getting base files and all kinds of problems when getting them. We sell them, but wherever you get it from, if you get it, ask some questions before you buy.

Good luck!!

Hey Don

A Q or two about the SCT PR

I have always thought it was way more easier to tune with than the Tweecer

I know you have had experience in the past with the Tweecer.

You seem to be saying there is a bit more involved with using the SCT PR.

I have looked at the SCT tuner files from time to time and they are very good if you ask me

Just looking for a bit of clarification
cause
Everything I've seen about SCT has looked VERY good

the tweecer r/t is nice since you can datalog. But it does get alittle stressing sometimes when you can't figure something out, and nobody else seems to know how to do it.

I first wanna say, I'm not trying to seem like a wise guy or anything like that
however
In all the time I have been involved with self tuning

There has NEVER been 1 Q I had that 99% of them had not already been addressed on the Tweecer sites.

Truth be told ... the other 1% had been addressed as well
and
It was those small few where I posted a Q on ... for clarification

These days, we got more helpful info here & on Corral than on the Tweecer sites in the early days

We even got EA
and
If you have never seen them ............

The SCT help files are EXCELLENT

I really do want to know ...... from YOUR perspective ...... Mine is not as fresh as some who have not been at this stuff for so long.

Do you feel you have no support if using the Tweecer/EEC Tuner self tuning method

How many times have you wanted to do something but could not find out how to do it

Looking forward to your input
and
If everybody thinks we need a new thread in Tuning ......

I'll join in over there

Grady, Basic tuning is tuning. It's the concepts and procedures that are sometimes difficult. The other difficult thing is knowing WHAT to change for cars with cams, strange mods, i.e. 'problem' cars. On a basic car, doing the same things you'll get a good tune with either. SCT is pretty complex mainly because the number of parameters you see will be daunting. BUT, with the base tune you get you really only have to worry about a small handful of them anyway. Doing a TwEECer tune is probably more complex, even though the software isn't as complex because you get the hardware and the software, then YOU have to do a base tune for it. The PRP community is really pretty good too on the SCT forum, but it's more tilted to later models. I do LOT'S of mail order tunes on later model cars that have engine swaps and doing these are often the most complex to tune. For example an old Studebaker with a '98 Cobra motor with a '99 GT processor. Or a 96-98 GT with 4v motors - these are a bear to dial in and for those I really need what SCT has. For a basically stock '95 Mustang you could get great results with an EEC Tuner, TwEECer, SCT PRP or any other tuning method as long as you understand the concepts and what to change.

Hope this helps???

i've never tweecered BUT, i had a custom SCT chip burnt for my car with dynotuning and its great......Especially since it got me up and running immeditially after my mods.....with no learning at all on my part.....NOW, however im saving to buy the "pro-racer" package, which has software and a burner for my chip so i can mess around and tweak as i change things.....I am very happy with sct.

Thanks Don

Tuning is Tuning ... I sure do agree

and

I also have told peeps knowing WHY to change something is WAY more important than learning some ...... software package.

To the original poster, BlueBleeder95 ..........

I do ask your forgivness with my hijack of your thread
but
when I see Don is hanging around, I take advantage of his knowledge when I have the chance

I have never used the SCT PRP or the PMS for that matter
but
I have fooled around a bit with the Tweecer

It has NO user friendly ANYTHING

That is not said to imply it is bad or not capable

In Fact ... considering its datalogging feature ................

I think it is fair to say ...... It can be VERY powerful for the average Joe Blow to tune his Stang.

The dl feature is so very helpful with drivability issues. In a nutshell, you have the ability to see how your car is hosed up with hard data. You then make changes and immediately have at your disposal ... hard data showing you are making progress ... no seat of the pants kinda thing

anyway ... enough of my rambling

You just need to keep this in mind with the Tweecer, you need a basic understanding (not complete) of how the pcm works in order to make improvements on it

You can't go wrong with any of the choices and I would talk to peeps who have uesd each to get an idea about them.

btw ... I got some basic Tweecer/Tuning stuff on my little site ... if you care to take a look.

If you have any specific Tweecer Q's ... Mustangless and myself are not the only Tweecer users here ... I'm sure you will find answers from many who are willing to help

Bring back this thread!

I'm thinking about swapping out the TwEECer for SCT tuning. The previous owner had it installed but I do not have the want or even a laptop to use TwEECer. It is a daily driven car, would it make sense to swap out the TwEECer for SCT tuning.

Is it running fine now with the tweecer tune? if so, just leave it alone until you do some mods which require that you need a new tune, then get an SCT chip. My 408 ran fine for several months with just a mail order tune until I got a dyno tune.

It is running rich as hell, and thats why I was wonder if I should switch to SCT now.

I have to wonder a thing or two before I could answer with any helpful info

Do you want to tune it yourself?

I guess I'm looking for more specific info about your concerns
