DNA SRS

For those not in the know, SRS is the revolutionary new tuning solution that puts performance re-mapping into the hands of the owner. Using SRS is fast and easy. On first being plugged into the car’s diagnostic socket, one press of a button takes an exact copy of the standard E.C.U content, and stores it within the SRS module. With this information, an authorized SRS tuner can provide either an immobiliser map, a valet mode map, a road performance map, or various track day or race maps. A SRS module can contain up to 8 maps including the standard map, making it possible for a customer to purchase just one map or a variety of maps for different applications. Once the SRS module contains the chosen maps, the customer may upload and download maps to the car’s ECU as required, all at the press of a button.

What makes SRS unique as a method of direct tuning via the serial port, is that the standard content, when fired back into the E.C.U, is completely standard and unmodified in any way. Other methods of direct serial port tuning add extra software to the E.C.U code for purposes such as identification or map switching.
Dealer service equipment would find such changes and occasionally be unable to interrogate or ‘reflash’ the E.C.U at all, thus invalidating the Warranty.

Programming via the diagnostic port using SRS solves the quandary of all owners who want extra power and performance, but without compromising their warranty. Another large ‘plus’ is that it takes less than 30 seconds to download a copy of the standard ECU contents and another 30 seconds to upload the performance file. SRS is currently available for:
Porsche 996, 996 Turbo, Boxster, 997
BMW New Mini
BMW 300D diesel range
Mercedes diesel
VW/Audi PD diesel
VW/Audi ME7 petrol engine range (including RS6, S4, S3 and Audi TT)
Land Rover TD4 and TD6

Hello John, I've just discovered the forum.....perfect timing i hope.!
Our Red W(00) 2ltr bug was for the chop due to several things that we need to sort. The wife does about 5 miles a day in it , then we do a few more milesat the weekend. It does'nt run that sweet and i would like to improve it's performance ..will chip/remap sort out both.? Other probs are passenger window reg/cables need replacing along with the front lower grille and valance (maybe put one in with fogs) if i can get either at the right price.
Help with any of the above would be fantastic.

Hi Stewart,

Well it does all depend entirely on the car, there could be a fault possibly but yeah as standard they could run alot better, there is a member on here with a tuned 2.0L might be worth a chat with her on how she finds the difference. Where abouts are you from?

Cheers

Ok John, I live in Bearwood, B'ham and work in Redditch.
From what i've read you're the man to see, i'm sure you will sort it for me.:D
What will be the diff in chip/remap or SRS..?

Redditch is only 20 minutes away really from me(Stratford-upon-Avon) so that's handy. The SRS is basically for using on new cars where you need to switch t to standard to go back to the dealer, on a normally aspirated car this doesn't matter as much at all. So your best option is the remap in my opinion. This will see 10-12+bhp but the main improvement people notice apart from the power is the improvement in smoothness of the delivery and throttle response.

Yeh, That sounds like a remap is what i'm after.:)
Can you let me know what this will cost and what the next step is.
Thanks
