That's what mine sounds like. I would like to see that reduced a smidge if possible. I'll write the programmer today.

SherifDep - driving during the winter is a personal decision, but generally I put my car away when they put the first salt down. If we have rain that washes the salt off the road then I feel free to take it out afterward. I also have summer tires and have to be careful when it's near or below freezing.

 

That video is with 100 Cells Cats, what are yours ?? 200 Cells ?? Do you have your exhaust valves always open (fuse removed)??

 

Does anyone know if the car will pass California emissions test with the Stage 2 Software? Want to know if I should revert back to the original file before getting it tested.

 

I was really worried about what the salt and mostly BRINE had done driving it all last Winter and when I finally got to see it up on the lift when they were putting the stock clutch back in, it was absolutely beautiful underneath. No signs of anything from when I had inspected it at purchase, except, the exhaust has toned into the deep ambers. Don't fear the Winter

 

I'm not sure if you are me this or someone else. I have secondary cats removed and valves always open.

 

Always flash the stock tune back and verify that the monitors are set.

 

I am not fond of this either.... To many pop pops... Never thought I would say that.... I would like to know if this can be reduced/removed without effecting power. I have not had the time to read mine to return the base file and would like to know if this is a possible request.

Please keep us posted. Thanks!

 

The service at VelocityAP is second to none. I sent an email explaining that I didn't like the excessive pops on overrun and a day later Chris sent me another tune with the pops removed (he altered the timing on lift off, I think). It's so much better now.

 

If he has a Stg2 or something with 200 cells, the catalysts monitor will fail. If he left the VAP tune and fitted back the OEM catalyst for the CARB test, won't be an issue. With the VAP tune on the these cars, I've always seen the monitors learn(even with 200 cells, headers..etc). Although doing a CARB test, if they see the headers and 200 cells, I'd assume you would fail on the spot..

If the original tune was flashed back, that would clear all the monitors and the car would need to relearn everything all over again, which might be near impossible if temp outside is hot..the secondary air monitor won't run/complete

 

In the winter (and technically fall and spring), the roads are never dry in Seattle. It hasn't rained here in over a week as of today and yet the roads are still not completely dry. This leads to morning ice every day (on the rare occasions that it's not raining) and there is almost no road that isn't on some kind of an incline. It's very hilly here. I don't drive my Aston in the winter. Instead, I drive cars that are a bit less precious. Even if I didn't care about the wear on the car, I don't care to subject my car to the questionable decision making capabilities of Seattle drivers during winter months.

 

+1 on this. The personal customer service and turn around time from Chris is 1st rate. Even after 6 months, he's still answering my questions. I can't endorse them enough. It doesn't hurt that the tune does a fantastic job of waking the engine up.

 

Hi fellow owners - recently joined this forum and want to give a big thumbs up to the Velocity AP crew. I ordered a flash tune and Scrape Armor bumper protector for my DBS from Stuart who is friendly, knowledgeable and highly responsive. As for the flash tune, Chris turned around my file in less than a day which was impressive and emailed a comprehensive layman's breakdown of what he modified to achieve the tunes I requested with pros/cons.

Reviewing the tune: swearing not permitted but holy **** and WTF - it's a world of difference, especially with the touchtronic (I believe these have a longer 1st gear?) Throttle response is much more linear particularly from a standing start which ideal for traction and tyre life. I suspect this will improve fuel consumption but will be difficult to assess given the temptation to drive aggressively. Arguments about poor bang for buck on a highly-tuned V12 from factory do not consider the improved driveability of this useful modification. Highly recommended.

 

 

Thank-you!

 

Seeing this thread reminded me...


Just got a smog check notice. I'm in CA. Wish I could get credit for driving a Tesla daily and use that for my Aston.



I also just flashed a new tune (VAP made some mods for me - great service).


So, how do I pass smog testing?
1. Leave it all as-is, Tune+200 Cells and hope for the best?
2. Swap back to OEM Cats and leave tune?
3. Swap back to OEM Cats and flash back to stock?


I assume I need to drive something like 100+ miles after the flash to get enough data into the system before doing the testing?


Any other pointers?
