Hello to everyone!
I'm a new member on this forum. I own a 98' Fiat Marea TD 100, and checked a couple of times the engine ECU with this wonderfull soft FES.
I cleared errors, and it also helped me in troubleshooting.
I use an Acer Aspire 5720G laptop, running on vista, and I've never had any bad experience with FES.
I'm about to achieve a modification on the engine. I wanted to monitor a few parameters, so I decided to change my EEEPC from Xandros to Windows XP (home edition), to allow me to run FES.
In addition, this little laptot is fed by a 9.5Volts source, which is perfect for me : it is esay to convert a 12V source to a lower rate
I tried 2 version of FES with this computer : 2.31 I never accessed the ECU and got disconected in the same time.
I had no problem with my vista version...
Then I installed the 3.3 version. It runs fine with vista.
With XP, I noted this message : Latency too high.
My vagcom interface, runs with the latest driver version from FTDI's.
I have to check, but I didn't notice this message on vista...
In order to access the Latency timer, I've had to add the REG_WORD,within the registry.
I set the latency to 1ms as advised, then I was able to monitor this parameter in the driver advance window.
My wonder is about : on vista, no need to add anything, an the parameters can be set directly from the driver advance window.
On XP, it is needed (for my configuration) to have this parameter manually add.
I know a lot of stuff might generate this message.
But I experienced a difference between Vista and XP on that point.
I hope, this can help to find a reason for this message.
Good ECU scans for everyone, and Thank you Yani!
Vince
PS : sorry for this long post!
12-09 update
I've just tested the connection this morning with my 2 computers on the car.
With Vista, I got a disconnection when selecting parameters to monitor ;
I use a unregistered 3.3 version and so there is a limitation to 4 parameters.
I got the possibility to xheck for a fifth one, but then the ECU had been automatically disconnected.
I haven't got this type of error with my xp version on my EEEpc, but as soon as I select more than 1 parameter, The message Latency too High raises.
With XP, I can see the warning message stating I have an unregistered FES version.
Could it be the point?
Just one little question : can I post pdf files? I took screenshots for the 2 operating systems.
I hope this will help,
Good scans to everyone! and continue to enjoy FES as I do
