Hi Olli
Been using your s/w very successfully ! Thanks for creating it.
One favour...I have made a bluetooth adaptor so I dont have to mess around with cables. Works a treat...but when I kill the ignition, the BT module of course vanishes. On switching igntion back on, it doesnt find the MBE again...that's ok I could live with that by just closing re-oping MBETool. But when I try to close I get an excpetion dialog, in fact for everything I then try to do...cliking, closing etc etc. I have to use task manager to kill it (Win7 btw). Even then it puts up a fight...eventually stops. I restart MBETool and hey presto...all working again.
Can you trap this ?

Hi Pete,

Could you check if the COM-Port vanishes when this happens ? You could check that in the Windows Device Manager.
My Software relies on having the COM-Port accessible as long as it runs. But I will check if I can to react on this in a better way.

Hi Olli
Exactly the same as physically unplugging the com port yes...it vanishes because the bt module gets powered off

Oli, firstly thanks for developing this software. I've had no end of problems getting original sotware to run on my 4.5 ajp cerb. Yours ran no problem first attempt on XP. I've had a quick play and car has been stalling at low revs and adaptives showing -0.4 on both banks but one going up to high 20s when increasing revs up to 2000 rpm. What happens if I press reset adaptives button on software? I suspect I need to get banks balanced but seeing that button suggests it might do something?

The adaptives are stored in memory of the ECU and they are re-adjusted everytime you drive. Resetting the adaptive means setting both adaptive maps to zero. The Ecu will then rebuild them. If after a long run one bank is out of the normal range you know that you have a problem on this bank.

Yes, I have made some modifications so it only goes offline after loosing the COM-Port without an error.
You only have to reconnect afterwards.
I'm only waiting to make the new version public, because I want to have implemented the Read Adaptive Maps before.
Unfortunealy I spent some time on my Wideband Lambda project which runs fine now, last week was the 3 Nations Gathering, next weekend is Zolder Continental Meeting.
If you send me a PN with your eMail, I could send you an interims version.

Yes should work...no problem with 64bit OS anymore. As I'm not using Windows 8, it could be that you have to be the Administrator or you have to execute it with Administrator rights.

What does the speed six community make of this? I am a bit new at reading an understanding what is good and what is bad! Thanks to all

Not going to be much help here other than to say you're over revving the engine when it's cold and the battery needs a charge spin

Seriously though I've had this programme plugged up to mine and the range and presentation of parameters is excellent, so good in fact that I actually understand some of it! Great job by Oli.

He He +1 on revs and battery!!

Olli's program is excellent, great piece of work which allows most of us to run this on XP laptops which the TVR Diag program never did reliably and at times, was so flaky!!

If you don't know what you are looking at or for? Then I suggest you take to a recommended TVR Indy dealer??

If nothign else it's miles out on Barometric pressure!

3.06V is beyond a dead battery.

I'd be concerned at water temp 10C and oil pressure 16psi as well.

I think you have problems somewhere.

Running on Windows 7. Comm port 4 is the only port that seemed to pick up a signal from the MBE?
Suspect that it is not getting the right readings as the car is running very well....

Ahh ha! Got it. PC was looking for COM6 so wasn't picking up the right ports. So..... now that I am getting the right readings, it seems to all be pretty healthy?

I am considering fitting this ECU, what are the thoughts of those who have already fitted it?.
Thanks.

The only thing that stands out for me is the oil pressure reading quite low. Other than that it looks very healthy.

Just had Dom fit his 4.3 in my Tam - that's about what my new engine reads when "hot". TVR Power's opinion is that it is a normal reading as when tested "wet" that is, using a pressure gauge on the engine, it is about twice that reading. Another TADTS for the Speed Six.

Regarding the wrong values:
I programmed the detection of the ECU over the serial port not very strict. So it can happen, if you have selected a wrong port which is responding in some manner, that the software shows random values.
But I see an advantage in this simple detection: The Software connects easier with the different ECUs and I don't need to make changes to the program for every MBE ECU which TVR fitted.

If you look in the footer of the window, you can see 'MBE Type found'. So the type is missing, should be something like 'ECU #94130116 found'...
