Mike, I like the idea of how you set up the switch for the exhaust valves, always on or always off. Since I am in the USA it is not practical to bring my car to you. Currently I have a switch (to ground) in my car that powers a relay in the boot that provide power to fuse #22 when the switch is closed. However, when power is applied the valves still open in the specified RPM range. How to I modify the wiring to the vacuum pump to be on all the time when power is applied to fuse #22. I am assuming that the pump gets a signal (either power or ground) from the ECU when in the specified rpm range. Do I need to disconnect that input or shunt the terminal at the pump?

Jack
I have a switch in my car that allows valves "on all the time", "off all the time" or controlled by ECU. You have to splice an SPDT switch into the ECU white control wire to the vacuum pump solenoid. It is also possible to change the PCM map for solenoid operation. I've attached the stock map. "1" is loud, "0" is quiet

Guys thanks for your time and efforts today looking forward to pushing the button wink
Yeti I hope you got back OK in the tupperware car wink
The car floated home minus any useful braking force, all part of the Lotus experience rolleyes

Great to talk to Mike and Bruce (and see poor old Adrian freezing his nuts off actually doing some work!) and get some final spec and timings for my engine. There's a good chance I'll be driving to Geneva with 650bhp under my right foot for those icy roads smile

It's all just very inspiring up there, turning everyday Astons (if there is such a thing) to cars that outmatch those at the very highest levels.

Oh, and there was cake too. Glorious chocolate fudge cake brought back from the pub to enhance the whole experience... Who wouldn't sign up for a new engine!!

We raised a slice to 'Cockers & Jockers', and the start of the 100 years cake wars...

I've downloaded the ECU file. Is it possible to change the "0" to a "1" with just a text editor?

The data is stored in 32 bit FP Hi-Lo HEX. You can change the data with a HEX editor, "1" = 3F800000
but you must have software to calculate and write the cksum correctly to memory.
The cost to do this is likely to be prohibitive to most ($5-10K US) except for tuners in the industry.


Anyone who has access could potentially set you up a file and sell you a "slave" OBD2 serial reader with the correct protocals.

Does anyone remember when it was all about 9/16 AF and flat bladed screwdrivers?

I have placed this post on the general forum but though I would add it here too.It relates to BR engineering a solution to my clutch issue and as a further example of great customer service these guys provide.

Earlier this year having decided to keep my 2007 V8V I decided to invest in some upgrades. Having initially decided to go for the BR exhaust and intake I then also decided to go for the lightened fly wheel and twin plate clutch. Anyone who has seen all these components cannot fail to be impressed by the quality and they enormously enhanced the car however I struggled from the outset with the ‘nature’ of the clutch on pulling away and could not get a consistent launch with judder often occurring. It began to play on my mind which did not help. The inconsistent nature of my issues made it certain the problem was with me and specifically my driving style respective to the nature of the competition grade clutch and not the components or the fitment. I discussed my difficulties with BR and firstly to see if it was thought time might improve matters. BR were keen to check the clutch was working as intended and after a test drive by Mike this was as expected confirmed to be the case. It was agreed I would give the clutch more time however, and in a very generous gesture bearing in mind it was neither BR’s parts nor fitment fault, if I found that I could not get to grips with the nature of the clutch and accordingly my ownership experience not enhanced, BR would develop and provide a solution.

Well a few thousand miles latter and whilst a more aggressive style was employed to some success, I continued to have issues. True to their word BR have now fitted a new twin plate organic friction plate clutch and lightened flywheel providing for me the perfect solution. Any pull away style is now drama free.

The choice of organic plate clutch now exists for any future customer – more options to consider!

I wanted to publicly thank BR for their help with this issue and applaud their commitment to customer service.

I had the BR exhaust, intake, lightened fly wheel and twin plate clutch upgrade several months ago and although I initially found pulling away difficult I quickly learned the technique.
This now means I can get all the power down quickly without the worry of frying the clutch and an expensive bill, I really don't miss the smell of a barbecue everytime you try to reverse up a slight slope!!
For a small amount of effort you get a lot of reward, I just need to decide what I can sell to get the next upgrade and will it be brakes or Suspension?

To Mike and team keep up the great work making the Vantage the car it should always have been.

BR will service your car with AM parts but cannot provide warranty fixes. They just serviced my DB9 very well and provided me with a mercifully short list of items that require warranty fixes by a franchised dealer.

[quote=BamfordMike]Its not all max power at Bamford Rose..... We are responsible wink and care for the community also..... we are charged with looking after an old timer......

1 of ten reasons you know when you are getting old..... You are asked to restore a DB7...!

Not just any DB7 but one of very few Works Special visual and dynamics DB7's.
I think this was after the run of 75 Alfred Dunhill specials and came at the end of 3.2L supercharged DB7 production.

She has a special paint colour, very special suspension system design that makes the car handle very well, AP racing brakes and body kit from Aston Works Service.

The DB7 comes from Spain and has not been that well looked after, used and cared for by the owner yes, but serviced and cared for with a keen eye..not really....

The hot Spanish sun has turned the paint, all rubber window trim and the interior a little tired. Life on Spanish roads has damaged the bodywork in a few places and use and time have taken their toll on normal wear items, but those that we see need replacing on any DB7 of this age.

The brief: Replace anything that might fail within the next 5 years of use in Spain away from any form of specialist care and return the DB7 into the visual and mechanical condition to enable reliable use and be proud of.

The works required:
Complete respray as every panel has damage or blemish of some form, as strange as it might sound the respray is the easier and more robust option than individual panel correction. This will require removal of all bumpers, windows and both doors. Complete return back to metal, prime and re-spray.

The engine is in fine fettle, so nothing more than a comprehensive under bonnet service is required up front. The gearbox requires rebuild because 1st gear rattles badly as does the differential. The mag wheels require refurb. The callipers will have a seal rebuilt and surface refurb. AP racing brake discs and pads require renewal. All four wheel bearings, x4 corner subframe V-Block bushes, damper bushes, wishbone bushes, droplink bushes, trailing arms and a long list of other more minor stuff.

We will install a front and rear parking sensor system to help protect against contact with high raise Spanish curbs.

The light is quite far away for the rebirth of a special DB7..... But after time and care it wont be
long....

....old habits die hard.... cant help wondering how difficult it would be to drop the 4.0L supercharged inline 6 from the Jag XJR in - i'm not quite sure why Aston went for the 3.2L engine and not the 4.0L anyway??

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Time for an update.... This project has now finished, the car is complete, the special DB7 is nothing short of a work of art and back in the hands of the owner for many a year happy trouble free motoring in close to the glorious condition it was in when new in 1999, in 2012.

The project spanned 11 months, over 400 man hours and £12,500 new parts applied to the car.

The project should not have taken this long in term of calendar months to deliver. When the car was stripped for paint and removal of the many components we knew needed to be replaced, the car was found to be very badly corroded meaning it didn't come apart nicely and unplanned corrosion correction works needed to be carried out. This meant unavoidable damage and often breakage to serviceable components that required removal to gain access to the broken component which needed to be replaced. This meant the parts list grew together with the man hours required to rebuild the car. We then found some parts one would expect to be kept in stock were not just not in stock, but obsolete meaning we had to use our engineering know how to hand make or resource parts elsewhere. Combine this time delay with the domino effect of the rebuild phase clashing with booked in Motorsport projects, road car projects, a repair and service workload growing as we grow as a company stretching our staffing levels and facility capability and not to mention the human element of staff holidays and sickness... Meant the completion date was far later than originally planned. We have learnt from this and should we undertake another restoration in the future, our plan of identifying the exact works needed and delivered within timescales would now be reviewed at set milestone stages of the restoration. Also and as many of you will know, when we move into our new premises behind our current workshop, we keep the current workshop for longer term projects. This means plenty of ramp and space for the longer projects such as this, away from the very different business of repair and service.

This learning aside, the piece of artwork created is worthy of a few pics and celebration.....

Here is a summary of the works and parts required;

Comprehensive service:
Engine oil, oil filter, spark plugs, spark plug leads, air filter, drive belt, air-con belt, brake fluid, antifreeze, PAS fluid, air con re-gas, fuel filter, differential oil, remote batteries, transmission oil and wiper blades

Here is an update to the Bamford Rose electronic switchable suspension system.

Since original fit to 'Jessica' and 'Diablo Blanco' we have now refined the installation with factory glass or plastic (whichever style suits the car) buttons to control both suspension in either stiff or soft mode. The 'Sports' button electronically overrides fuse 22 and when combined with the Bamford Rose exhaust manifold and catalyst package, the exhaust note when the bad boy sports button is pressed is devilishly glorious, when sports mode is off, lurking in the background, even with the Bamford Rose exhaust manifolds and high flow 200 cell density cats, the exhaust note is whisper quiet.

Here is an example of the button fit in either Ski-slope or centre console locations and a description of suspension set-up





The damper curve we wanted for our upgrade suspension system resulted in a stiffer set-up than Aston sports pack, but a ride that harsh all of the time would not be good which is why we decided to develop the electronic switchable system to return comfort. In stiff mode we are slightly firmer than Aston sports pack, in soft mode we are softer and more comfortable than standard Aston road car damper curve – this really is the best of both worlds. Suspension is very personal and we understand this, there is a certain amount of tuning / settings we can adjust to get the car handling exactly the way you wish once the system is installed.

An update on the Bamford Rose lightweight flywheel and twinplate clutch...


We found our performance upgrade projects are not there just for enjoyment - no, they rehabilitate lives too...!!

The owner of this fine car who had our exhaust manifold and catalyst upgrade last year......

BamfordMike said:
Bamford Rose had the pleasure of meeting Mr CR, a jolly pleasant and interesting fellow, lucky owner of the beautiful Vantage pictured below - A quite rare midnight Blue exterior colour with a contrasting midnight blue and cream truffle interior.


The midnight blue beauty was a completely stock 4.3L on arrival and left with the Bamford Rose race exhaust manifold and catalyst system together with the sports induction system.







Got back in touch a few weeks ago needing the lightweight flywheel and twinplate clutch upgrade, not because he wanted to compliment the Bamford Rose exhaust manifold and cat upgrade with a yet more responsive engine from the lighter flywheel, or because his standard clutch had BBQ'd itself to failure.... The owner had recently broken his ankle and the heavy standard clutch pedal meant he could not press well enough to drive properly meaning he could not drive his pride and joy...! He wanted the lighter pedal the powerful sintered friction plate twinplate clutch returns.

He got what he wanted and we rejoined car with owner.....


We have updated the flywheels to be lighter and of a 1 piece construction instead of the starter ring shrunk and welded onto flywheel body, here are some waiting for homes....



We have also lightened the flywheel further and included a lightened front crankshaft damper pulley to reduce intertia and allow for an even more freer revving engine....
Upgrade product on left, standard on the right.



The 40Nm / 40BHP increase the exhaust upgrade returns, combined with freer revving engine and a clutch strong enough to handle the extra grunt really moves the Vantage on in the performance stakes. It bridges the gap between 4.3L and 4.7L for 4.3 engines and makes a 4.7L.... well, simply electric. A Vantage 'S' with this kit on is simply awesome - as ROBGT might tell us.....
