On a 2010, yes the decats with throw a CEL for cat efficiency. We can resolve this with ECU Tuning. Some people have used O2 spacers with different levels of success. The easy answer is to tune it - another 30HP or so, and the light will never come on. Problem solved!

 

With exceptionally minor differences, it's the same tune.

 

Hi Stuart,

Your website gives an example of gains on a 4.3 power pack with exhaust.
Do you have data on a 4.3 power pack without exhaust?

That might help me decide on staging up over time vs all at once...

Thanks,
Ryan

 

It's the same, the exhaust doesn't make any power.

 

How about going with the x pipe for secondary cat delete - any cel then? I’d like to do the tune absolutely last if possible. I like doing upgrades in steps/phases so I get a feel/ear for each step

Could you post a sound clip of the gt4 supersport exhaust component you offer on a mostly oem car? If you could post sound clips of the x pipe as well that’d be greatly appreciated!

 

Since you have a 2010, you do not have a separate secondary cat. Your catalytic converters are integrated units which contain both primary & secondary in one assembly. So if you want to remove the secondaries with a bolt-on part you have to either delete the primary or replace with a 200 cell unit at the same time.

We have some clips on youtube with XPipes fitted, but they are in combination with 200 cell sport cats, which I'm not sure is what you're looking for?

I don't know that anyone has posted a clip of our GT4 exhaust on it's own, but this is what it will sound like:

 

Is the ECU tune a plug and play I can just put in myself?

 

99% of our customers do the tuning process themselves. It is not 'plug & play' in the sense that the tune is not loaded to the programmer, you read the file off the car, email to us and then load the MOD file to the programmer, and flash to the car.

 

Oh man I like that a lot! Very gt track sounding with some raspiness, how is the level in terms of loudness? Any interior drone? Will def sound more refined than decatted, hmmmmmmmmmm....

 

Drone... any time you increase the volume you're going to hear any resonance amplified in the cabin. V8's aren't very bad for that though. V6's are terrible. I think you would find it okay.

 

So I would need to hire a programmer?

 

No. You buy the product, we send you a programmer. You keep the programmer, it's yours, it marries to the vehicle:

"Each customer receives a hand-held Velocity V-Tech ECU Flashing Tool:"

Just ordered my tune. Thanks Stuart!

 

How often does Aston Martin update the ECU program, or even flash the file on the car?

In other words:
* Do I need to reflash after any service updates
* If I'm sending you my existing file today, to be updated by you for reflash, how can I get an updated file if AM updates my factory default file?
** I'd there a charge for subsequent updates to AM base file

Thanks

 

I wonder if people without physical mods benefit from this, and also for 2016 models. Does it void the warranty? Can dealers notice it? Sounds interesting
