How do I know my Aston is feeding in fuel, which reduces maximum compression braking? Well I monitor "Instant MPG". When I coast downhill in 6th gear I see 99mpg. When I shift to 5th, I see 67mpg, and in 4th I see 38mpg--that's how I know. My other cars continue to show 99mpg when I coast and down-shift.

 

Just having my current map analysed by Eurocharged.

Set up is High Flow headers, Cat delete, X-Pipe, air filters.

Looking forward what power gains can be acheived with such an unrestricted setup.

Here is dreaming for more then 440 bhp

 

who's headers? where did you get the x pipe? Fabspeed? Cat delete? no cats at all? I have done that on my 85 911 but was not sure you could get away with that on this car without having codes (check engine lights) on?

 

RSC Header
Custom x pipe
Custom Cat delete pipes
Emission code to be removed via remap but does not affect performance i.e. no limp mode

 

Correct, Jerry can remove CEL permanently, that's the beauty of a custom tune file that is tailored directly for you car.

Can't wait to hear the results for your tune Vergis, do you have any tuning at all right now? Or is it bone stock software?

Going to take mine back hopefully by end of next week for some more fine tuning for even more performance. It's definitely a screamer now! I cannot even imagine with headers and X-pipe

 

How LOUD do you think the final product will be? Please post a video if you can.

No. 400 yea!

 

X Pipe reduces sound by about 30-40% compared to just leaving in the standard H pipe. So while its loud its not madly loud.

 

Im running an old map that was done when it was stock standard . It made a slight difference but nothing major. I really want to get a new map done asap and see what figures Eurocharge can give. This could be groundbreaking stuff.

 

I had the map done last week and the battery I guess has to have a good charge... So he told me to put a battery charger on the car? I said, ok where the heck is the battery? I don't want to look like a fool, however I still didn't find it? where is it? I found the area under the hood where you hook up a charger (at least that is where I hooked it up and it worked) but have been looking online everywhere I can think of and still can't find the location of the battery? Can anyone of you guys help a guy out? I took along time to find the one in my Q5 as well

 

The battery is in the shelf behind the passenger seat. Can also plug in the battery conditioner in the boots (cig lighter plug above the fuse box)

 

I tried to get in there? is there a trick? I also have the conditioner( it came with the car) do I just plug it in the cig lighter plug? To tell the truth I have only had it a short time put a 125 miles on it, have not had time to learn or play with it. appreciate the help!!

 

There is a plug (lighter type) in the trunk… to the right rear, you will see a panel, open it and voila, you will find it.

As for the rear shelf, there should be a tab in the back center of the carpeted shelf. If not you will have to pry it open. I don't recall but there may be foam insulation on top of it.

Don't you have an owners manual?

 

Just plug it in the cig lighter plug - either the center console or in the trunk. Most would suggest to plug it in if not driven 2-3 weeks.

 

no, we kinda... it came in pieces. I found the tab in the back removed it and found the foam. is the battery that small to fit in that 4 inch space? or do you have to remove the back panel to change it.

 

NOTE: The one in the trunk is what is recommended by Aston. The cigarette lighter may not be "live" if the ignition isn't on.

I'll take some photographs if necessary…

It's under the foam on the passenger side.
