Hi maestro,

Thanks! clear now.

I now know your reference and I understand why you read something else then I do in our V4 user-manuals:
contrary to the V4(S) manual(s), the V4R user-manual is explaining in much more details the functionality and limitations of ‘Sessions' and ‘Laps' for this V4R model!

Here you can download both to compare differences.

Since the V4(S) user-manual is much less descriptive and not stating this 'max 30laps/ 4 session' limitation, we will need to check in reality if this functionality looks/works the same on the V4(S) with a DDA's installed post-factory as an extra accessory.

Still, after reading the V4R user-manual, it’s not clear to me if this 'max 30laps/ 4 session' limitation mentioned only in the V4R manual is applicable for the V4(S/R) its internal ECU memory and/or (even) the 16MB DDA USB stick.

I’ll hereby post these English snaps of this in your V4R manual clearly mentioned 'max 30laps/ 4 session’ limitation, may be the other guys (e.g. Thorny or MTB) know for which (ECU/ DDA) memory it is applicable?

my idea is that the data are streaming uninterrupted from the OBD to the DDA port and the 16MB memory gets just that 16MB then is full.
My friend with the R will make some tests in the incoming days(maybe already the 3rd of September),and if I will be free,I'll test my aftermarket DDA as well the same day,
open OT
together with the new DTC EVO 2 ;-)
Thanks from RdashP

now I should find the instructions on how to mount the GPS antenna in front.
It appears that in the instructions given,there is only the installation under the seat.
I also need to put the DDA memory in a more accessible place

Correct. The instructions and supplied cabling in DDA+ kit 96580172B are indeed only for rear-mount.

Why would you want to go through the trouble of installing the GPS antenna upfront if required cabling is not present in the bike nor additionally supplied in the kit and LoS between front- and back mount is about the same, therefore no benefit to Satellite reception quality?

Trackmaniak did this in a better more logical place under the seat.
I will try to do the same once I start using the DDA stick. Unscrewing the seat each time is indeed a pain in the @ss

The fact that the gps signal could be weakened by the fsirings and not being in DIRECT LoS,make me believe that the front is better.
For the DDA dongle,I have no tail storage on my race fairing.
Maybe I could try with a small door on a side.

If your fairings (back) or windshield (front!) covering the gps antenna are standard plastic (non-carbon/-metallic), it’s only your own body similarly shielding LoS in front- and back-mount and possible nearby magnetic fields interfering with satellite signal quality.

Checked the V4S-MY19 and V4-Speciale-MY19 user-manuals as well and both are not explaining DDA+, Sessions and Lap recording in same details as V4R (MY19 only) manual does.

Not even the Speciale manual which model, same as V4R, has DDA+ factory-installed! #factoryf@ckup

in the front the antenna is "exposed" to the sky,
in the back,it underneath the fiberglass fairing.
It seems better in front,to my knowledge

Here you stated you were tracking the V4 with a V4R fairing?
Is this an aftermarket non-Ducati fiberglass racefairing or the original plastic Ducati V4R fairing?

Either way, both fiberglass and plastic (same as plexiglass canopy) are non-blocking materials for largely unrestricted GPS Satellite reception. Unlike carbon and metal are restrictive, as previously stated.

I'm very interested in your EVO2 experience on track.
Too bad it costs almost Eur500 to have our V4(s) upgraded to this latest version.

Besides, I'm unsure if I will even benefit from this optimised 'EVO2' DTC mapping if my track racing level is already nowhere near the traction limits of the V4 with 'old' EVO1 DTC mapping?

Too bad it costs 700+ to have our V4(s) upgraded to this latest version.

Besides, I'm unsure if I will even benefit from this optimised 'EVO2' DTC mapping if my track racing level is already nowhere near the limits of the V4 with 'old' EVO1 DTC mapping?

I go by step:

I race with an aftermarket fiberglass fairings that replicate the V4R fairings,included the the winglets,due to a better cooking(I am not a poser )

It is correct what you say about the non blocking fiberglass.
It could be that I try both positions and see what works better.

For the EVO 2 it would be great that we all suggest Ducati to include 2 years of free updates on software,from the purchase(like it would be linked to the warranty).
I believe that they could do it,and it would be a PLUS on the marketing side.

Anyhow I will tell you how it is,from my point of view,on the track only thoug.
Thanks from RdashP
