Does anyone know if there is any software on the market yet which can actually do anything with the output of an OBD11 port on a Spirit series which has such a port please?

i have an inexpensive BT plug but most of the time it doesn't want to communicate with the ECU. And when it does, neither Torque nor OBD Doctor can interpret any results it gives on my smartphone.

is there any software developed yet which can initialise the ECU properly and interpret any output from it, preferably on my laptop please? The Torque interface is pathetically klunky and things like autoingenuity has a scary looking site which seems designed only for garages which can use them a lot to get proper value out of the cost!

Or does the plug itself do the initialising and do I need to buy a more sophisticated plug?

My car is doing about 9-12 MPG and surely something in OBD11 can tell me what is wrong without the proprietary Bentley codes?

Dear Jon,

Would this be for your 1996 Brooklands?

I can tell you that 1993-1995 models will need a Motronic 3.3 software, as used by BMW in the E32/E40 V8's (PLEASE note this is for the 6.75 l. V8, which actually runs in a BMW-like ECU).

When I am done with mine I will map it and will come to you. Bentley / RR could not develop own controllers hence a lot is piggied from other manufacturers, therefore I am confident that we will find a software that can interface with it.

Best,

Lluís

PS: Do you have a check engine light on? 9-12mpg is not nice indeed and there can be a million causes, but you do not need OBD for this.

I would first ask: how does the car run in terms of performance?

How are the obvious (plugs and air filter) and less obvious suspects (cat and pre-cat) that may impact performance. Have you checked timing (faulty CP sensors) and which type of Flow Meter do you have? Hot Ceramic plate AFM's are very delicate and sensitive to dirt with massive fuelling implications. They are used in the post 1993 cars up to the Zytek models that drive on MAP (pressure). You can easily access it from the filter housing and clean it gently with contact spray.

Best,

Lluís

Jon, do not touch by any means the AFM in case you have one (not sure what car you have) and simply spray contact cleaner on the plate. They are extremely breakable.

Thank you for that Luis and yes, it IS for the 96 Brooklands. I do have the OBD11 interface as i implied when i said my car "has such a port". Is there a serious problem with the contacts on the MAP sensor getting constantly dirty? I had exactly this problem a year ago and having tried a few new sensors (a generic and a Bosch which Bosch said was correct for my car!) neither of which worked at all, I did carefully spray the contacts and the problem went away. But I figured the dirt built up after a few decades use, and didn't realise that the problem could occur again within a year/few thousand miles! I thought that the MAP sensor problem was one which i could now rule out, especially where performance is fine

But I did start to wonder when, only yesterday the check engine light came on pretty much as soon as the car got hot: And then, amazingly, after 45 minutes of highway driving, it went off again!!

Do you know if anything changed in 1996 to comply with the US regulations or were the systems the same, but there was suddenly that port in the glove compartment? Surely if the ECU is the same as a BMW E32/E40, I should be able to use the Torque settings for that car?

Hi Amanda or Jon or both,

Yes, from 96 MY OBD II ports were compulsory. Nothing changed though in as much as I know in the k-l lines which communicate with the ECU that use as ISO 9141 (?) protocol. Very possibly the problem is waking up the ECU.

I think you need to check -there are older threads- on some of these:

TPS
2XCPS
MAP
CTS (top one in the thermostat pedestal 0-5V)
Air Filter
Coils, cables and Sparks (8X)
Air/Vacuum Leaks
Lambda


I hope all is correct in the information above. Such a high fuel consumption can have many causes and MAP / Lambda will have a massive impacts

Amanda: from my limited experience air leaks can be a killer as well as a bad lambda and CTS. All are relatively cheap to fix.

Yes, it is probably one of those, most probably an air leak if it is not the MAP contacts again: Can any software identify any of this please? Or do I have to get a proper adapter as opposed to the $5 eBay Chinese one?

The only real symptom I can identify is that from cold, the car now needs to be turned over for 5-8 seconds before the engine fires. If I take the car on a lengthy run at high revs to clear off any buildup on the plugs and then turn the engine off, it doesn't make any difference to how long I have tu turn over the engine from cold to get it to start.

As I said, I cannot give you the answer, but a CTS or a Lambda (plus any obvious leaks) would be clearly my main concern.

I note that software will tell you that a lambda is faulty, but not why...
