SC Tuner's on dyno?

[SLoW_SHO_316]

Theres a few places around me that tune Mustangs with an SC Tuner program on a dyno. Is this something I should look into for tuning my f/i SHO because my tweecer is being a PITA?

Any detailed info would be greatly appreciated.

You should really ask Axianator , it doesnt get better than him. (about tuning with a tweecer)

Pick up the SCT6600 chip, and then take it down to your nearest SCT Tuning place. They'll use the Advantage software and tune you up. I've seen this software, and I think it is either just as good, or better than the TwEECer. One thing is, it looks a lot more user friendly. I've decided to go this route (sorry Adam :cry due to the fact that I will be getting a full dyno tune, and I'll have my car all tuned up in a day .

There is a guy here that does superchips on the dyno and will do them for a sho, pm me if you wanna know more.

 

[SHO Dude]

I know a guy in Atlanta that can do it as well.

Out of curiosity, in what way is your TwEECer being a PITA? Is there anything I/we can do to help?

Also, when you speak of an "SC Tuner", I assume you're referring to an SCT (Superchips Custom Tuning) chip burning package and not the SCTuner tuner kit that was offered by Jason King and Sypros G. many moons ago? For those who are not aware, the two kits are not one in the same thing, though their names are often interchanged and misunderstood.

Don't worry about it, man. The TwEEcer is only one path of many paths that one can take on the road to EEC tuning.

Also, while I agree that the SCT chip burning packages offer a much more informative and user-friendly interface than the TwEECer, I thought I should note that, with the exception of the shifting pressure slope scalars on the '94-'95 D4U1 calibration, neither SCT package - whether it be the SCT Pro Racer package or the dealer-only SCT Advantage kit - offers any additional parameters or functions above what you would get if you ordered a TwEECer and applied the latest software updates from Josh's site. In fact, up until recently, the SCT packages was neck-and-neck with the latest SHO-based TwEECer software updates in terms of parameter count.

I have a few issues that I can't seem to fix. I'm sure it's got something to do with the fact that I'm still running on a stock MAF, but I have a few lean spots @ WOT, I can't figure out the idle, etc... small things that just annoy me. I'd rather just pay someone to professionally tune the car for 9psi like it came stock with a turbo, rather than constantly fooling around with tweecer. Don't get me wrong, it's a great program, it's just not for me right now. I found a SCT tuner near me that will charge 125$ an hour dyno time and gaurentees everything, and free reburns for life. I just need to pick up a lightning 90mm maf, a superchip, and one of Josh's FPR's. Then off to tuning I go

I'd like to hear more about the Super Chip custom tuning. I contacted the Super Chip people and was told that they no longer do custom tuning? Is there anyone in the Pacific Northwest that does this?

My car would run a lot better with a better air fuel ratio at high rpm, but its hard to justify spending a lot for another 30 to 40 horsepower.

As an SCT dealer, I'm going to recommend you go with the TwEECer.

There's basically nothing in the SCT software that isn't in the TwEECer software and vice-versa. Now, that's not 100% accurate as there are a handful of functions that don't currently crossover, but to 99.9% of the world they are irrelavent.

The advantage the TwEECer has on the EEC-IV processors is the real time datalogging capabilities (presuming you have the R/T version which is essentially mandatory with a F/I car). To do this with an SCT chip is going to require another piece of hardware and software. Finally, if you want to make any changes to the tune yourself, with the SCT chip you're going to have pony up for the Pro Racer Package, which means that you're going to end up with a final price tag of over $1000 to encompass all the TwEECer functionality at about half the price.

You don't mention a wideband which is critical to getting the MAF transfer function dialed in perfectly, and trying to tune with the stock MAF in your configuration is a complete waste of time because you're probably ******* it at moderate TP.

The bottom line is that whether you're tuning with SCT or TwEECer, you're manipulating various functions, tables, and scalars to achieve the desired performance. While both products do it a bit differently, with proper time and understanding either will provide the same result.

With Josh, Adam, Jason and others, you have access here to SHO owners who know the TwEECer inside and out and can help you get done what you're needing. While there are a lot of great tuners out there, and ideally final tweaking of a tune should really be on a dyno, dealing with someone who doesn't have the same SHO experience as members of this forum is going to cost you a lot of time on the dyno while they learn your car.

I know it's a little confusing, and quite frankly I'm puzzled why SCT doesn't explain it better themselves, but basically we are talking about what are now two completely separate and independent companies: Superchips, Inc. and SCT (Superchips Custom Tuning, LLC).

You can go to SCT's website at http://www.sctflash.com and use their dealer locator to find a local custom tuner near you.

Thanks for that SCT info.

As Chris expertly pointed out, your lean problems are almost certainly caused by a "pegged" factory MAF that is seeing more airflow under boost than it is capable of reporting back to the EEC. Also, given that most dyno-tuned chips rarely take into account the more important aspects of a street-driven car, such as idle quality and part throttle cruising, you may eventually find that it is better to spend some seat time with your datalogging-capable TwEECer than too much experimentation time on the dyno.

i can use some help?

While it may be long overdue, have no fear - help is on the way.

i heard of wide band 02 sensors but where can i get a wide band maf? i also already have the tweecer RT.

You can buy one of the PLX wideband O2 kits from Josh at http://www.shonutperformance.com as well as an 80mm or 90mm lightning MAF.
