what is the best for a vette 2009, automatic, base model ( for now ) , Diablo or SCT ? and why ? thanks

 

I would wait until you do some basic bolt ons and then go with a custom tune made specifically to your vehicle.

 

thanks i will do that but.... who is the best ? SCT or Diablo ?

 

Depending on where you are located, I would try to find a reputable shop with experience in tuning these cars with HPtuners or comparable software.

 

I wouldn't waste my money, especially if you are going to do mods.

Once you mod then the basic tuners are worthless. Get a pro to do it, a lot of times they will retune for free after adding headers etc.

I've seen more activity with SCT though so maybe them?

 

Huh?

Plenty of tuners use the Diablosport to tune with. I don't get what you're saying here.

Anyway...check out the scan/tune forum, you might find your answer there.

 

No offense, but anyone tuning with a diablo sport is a horrible tuner. Maybe they're sending you a can tune with a diablo tuner, but that's still not a real tune. It's a can tune and is a waste of money. It's a tune you use to get your car running before going to get a real tune.

OP, the answer to your question is that they are both a waste of money. And why? Well because it's not a tune for your car. They took some random cars, tuned them, averaged everything, and sell it to the masses. And believe it or not, what is right for one car may not be right for another.
Hence, everyone says that you should go to a shop. Which is also the best idea. Many shops will even retune your car for a small fee, whenever you add addition modifications. And all of this for the same price as the cheesy diablo tune.

 

What?

Fill me in on why you can't use a diablosport to make custom tunes.

 

Not sure if they fixed it in a Diablo, but the version I had would not allow my email tuner to adjust transmission performance factors. My tuner at the time recommended I buy an SCT since it could be used to adjust all of the data points. Someone else said it: a true dyno tune is the best regardless.

 

Fill me in how you can. You don't use the diablosport, you use CMR to make a tune. And that's $2,500.

 

I would honestly suggest our tools.
We have been tuning GMs longer than anyone else.
We offered the first ever handheld for a GM product years and years ago, and we were the first to ever offer tunes for the E40/05 Vettes at that time as well.

Our tunes are extensively developed, check the tune/scan section, there are quite a few positive reviews of our tunes on LS2 and LS3 cars.

I'd love to take this opportunity to enlighten some of you guys...we support full custom tuning through our CMR software. It will let you do anything the other guys software can short of custom operating systems. You can use our CMR software to safely tune most any combination you come up with short of big boosted applications.
We have hundreds of customer with CMR tuned head/cam setups, stokers, and bolt on blower kits.

Again, you are a bit misinformed here....some of the best tuners in the country use our CMR software, why, because having choices to offer your customers is the best way to stay in business these days

Not to mention, our CMR software, combined with one of our handheld devices gives any tuner a great remote tuning solution since the tool can datalog and you can transfer tune and log files via email simply and easily. This means the guy receiving files does not have to keep a copy of software on a PC and go out to the car each time he wants to make a change with the laptop, just plug the tool in and go.

Then there are the more obvious benefits of our handheld tools, like the ability to make simple tune changes in the driveway (the tools offer the most end user adjustment of any handheld tuning device) like tire size or gear ratio, or even add or remove a little spark at WOT.

You dont get that for the price of a dyno tune. Nor do you get the ability to read/clear trouble codes, or datalog unless you have your own software to do it with.

What if you need to go to the dealer for service?
Do you just let them flash over your dyno tune, or cross your fingers and hope they don't? Then you are stuck hunting down the tuner to reload your file on his schedule...not for me
Not a problem when you have a handheld in the glovebox...

Then theres the whole question of the CVNs in the PCM being changed when you use anything besides our devices, which can lead to warranty issues. Maybe not an issue for this particular 09 model, but likely an issue for many of the newer car owners.



All of our current tuners (inTune annd Trinity) offer TCM support, and CMR has support for custom TCM tuning as well.

Thanks!

 

Look at my post above yours, I just posted about CMR.

 

I'm just a facts type of guy (Just the facts Ma'am).

In the C6 1/4 mile performance section look at the "bolt-on" Grand Sport times.

I "ONLY" have:

1) CAI (home made)
2) Headers (1 3/4") with the stock (430hp) mufflers.
3) A "Canned" DiabloSport 93 tune. Yes that's right.

Results= 11.52 @121.89 MPH on four OEM runflat tires & 260 lb. driver.

The Second Place "bolt-on" Grand Sport record holder has all the stuff mine has but a more expensive CAI, Headers, and I believe a "PROFESSIONAL" DYNO TUNE to boot. RESULTS: Over 4 tenths slower!!! Look at his MPH too!


I think the tunes may have something to do with the results; Don't you.

PS: Car now has over 16,000 miles on it and runs, idles, etc. as good or better than stock. What more could you want.

 

Have you ever used a Diablosport Intune or Trinity programmer? Or have one of their reputable CRM tuners do a custom tune? Because you are sure talking like you have not!

I installed one of Diablosport canned tunes and my car's throttle response improved along with stronger pulls throughout the entire rpm range. I went a step further and had one of Diablosport's CRM tuners do a custom tune, "Diablew custom tune". Lew did a great job on his custom tune. Third gear pulls are amazing along with further improved throttle response and stronger pulls throughout the rpm range than the canned tunes. I had K.R. issues with the stock tune which were eliminated with the custom tune. Other tweaks were also perfomed in a custom tune which I will not go into. My car is a manual so shifting will be improved for the auto folks.

The Intune programmer is a very valuable learning device. Download your data log files on your PC and transfer them on their free Dataviewer software to see what your car is doing in real time. I highly recommend Diablosport programmers and their CRM tuners, especially "Diablew Custom Tunes!"

Why we are so quick to put down another product that we never even tried goes beyond me?

 

Wheres the "LIKE" button?

Thanks

 

I don't think you understood his post. He said that you can't tuner with the diablo sport, maybe meaning with the handheld device itself. Not that you can't load tunes on it and put it on the car

 

Guess I don't need to now that Mike gave a nice dissertation on it.

 

FWIW, the tuner itself has end user adjustments available for rev limiter, speed limiter, WOT spark and fueling broken into 3 rpm ranges, idle speed, fan settings, and more...

Thanks

 

A CMR custom tune usually isn't more than a couple hundred bucks.
I had a diablo predator on my ls1 camaro when they first came out for the LS1's. I also had a diablo on my srt8 300c. I did use the user adjustable parameters on the diablo while doing dyno pulls with a WB on the srt8. At the time there wasn't much for tuning the srt8's so the diablo worked well on the hemi's.
I also have had cars tuned with efi live and hp tuners. They all have there place but the diablo is far from worthless and can be a great choice, just depends on the user's needs.

 

I understood his post. You can change parameters of your oem tune, canned tune or custom tune. For example: timing in three different rpm ranges, injector slope, adjust P.E., fan duty cycle, cags, tire diameter changes, shift firmness for auto trans, etc.

The point of my post is "why criticize a product when one is unfaimiliar of what the product can do?"
