Hello
I've trying to review my fuel map with DTA S40 , but can't change value with F8up/F8down ... and have some message as "Cheksum Error" in red
Did i forgot something?

Re: Trouble with fuel map
Check sum errors mean there's a problem reading and writing the data. If this used to work on this PC, it probably means Windows has "helpfully" updated your USB driver. Change it back to one of the older ones.

Re: Trouble with fuel map
Ah. Assumption and all that.
Check your port settings in the Control Panel -> Device Manager -> COM and LPT ports.
Make sure they match the values in this document:

Obviously you can ignore the USB references.
If those are correct and you're using the same cables as before, you've got a hardware issue, either on the PC, the serial cable or the ECU.

Re: Trouble with fuel map
All values are correct,
I forgot to tell you that this is the first time for me to manipulate without knobs, that's why i think i forgot something about process before manipulate (+ or - fuel).
Sorry for my english " so so "
Many thanks

Re: Trouble with fuel map
No problem, your English is better than my French.
There are different short cuts depending on what part of the software you are in. The different
IN 20 x 14 Main Maps
Alt Up Arrow Nudge Cell to Higher Value
Alt Down Arrow Nudge Cell to Lower Value
Alt Page Up Coarser Nudge Cell to Higher Value
Alt Page Down Coarser Nudge Cell to Lower Value
IN REAL TIME MAPPING
Shift F7 Ignition+
Cntrl F7 Ignition-
Shift F8 Fuel +
Cntrl F8 Fuel-
Cntrl P Knobs on/off (toggle)
Cntrl C Knobs coarse/fine
Cntrl K Stop Engine
Cntrl I Interp on/off
F6 Send Traced Cells to ECU
F7 Cam 1 target on left Dyno Box Knob
F8 Cam 2 target on right Dyno Box Knob
However, if you have check sum errors, you have communication problems, so I'd fix those first.

Re: Trouble with fuel map
I'm having a similar problem, only F4 seems to work. Also when i try to change the map sensor values it won't allow me to save and a messgae pops up sayin 'idle parameters too low'

Re: Trouble with fuel map
Where are you trying to set 'map sensor values' ?
There are just 2 settings for this sensor in 'DTAwin'
Presure at 5v i.e a 3 bar sensor will be 300kpa
And the offset +/- to correct to 1bar atmospheric at sea level
Have you made your mind up to use TPS+Map compensation as your load or Map as load????
I'm a little confused as you say you use an E48 but your signature says S40 Pro ??
On the DTAwin software the idle control page shares the pressure sensor calabration, you need to check that the idle parameters are in range when you save otherwise you will get the warning i.e.
Max duty Cycle % (1-100) = 0, this therefore would not be allowed
Where in the world are you, you may be next door!

Re: Trouble with fuel map
When i signed up to this forum it wouldnt accept the E48 option for some reason.
Re map sensor, i'm planning on tps vs rpm with map for correction. From what ive been told this is the easiest way to do it unless someone here can tell me otherwise. Please just bear with me as i'm still gathering info on how it all works
