Hello members,

We had this stunning A35 AMG in for Stage 1 software calibration

Got to work as usual checking tyres, dif, coolent, oil and fuel quality while running diagnostics on the vehicle while letting everything cool as these run very hot and can soak while sitting very easily.

Multiple runs and sweep test along with different RPM tests.

Logs went to plan and vehicle was behaving as we would expect to the customers delight.

OEM - 302bhp and 400nm

REAL - 301bhp and 410nm

Stage 1 - 343bhp and 482nm


She responded beautifully

Below are plots, shots and runs....

For any enquires please feel free to pop an email over to info@gadtuning.co.uk or call direct on 05603 67 21 09

Thank you for posting.
I've not followed every bit of remap information posted on the forum, but those plots on the standard map aren't like I've usually seen (on other data you've put up).
Do you know what's going on with that variability across the rev range, especially torque! It looks all over the place. Is that common on the standard Merc map?

Nice to see there's some really smoothing benefit from your remap. I'm sure that helps drivability/predicatibility on the road and I don't think I'd like the on-off-on nature of the standard/factory map power/torque delivery.

The power of the original vs GAD map at 4,500 rpm is total comedy! 4,500 rpm is surely frequently used (unlike 5,800+ rpm for example which is where the factory map gets its peak power), and the power difference looks something like 230bhp vs 320bhp; circa 40% improvement in real-world rev ranges. How can Merc even release that!?

Rather odd looking stock plot? CPC fiddled with afterwards?

Yes I was going to follow up we are really not sure why the stock readings kept repeatably coming out that way! The link on the Dyno was running so power wasn't being shuffled by the cars AWD system, it is indeed a very strange power and torque curve higher up and its not like the car then came off the dyno for tuning it stayed on there strapped down so its not like it went back on and was strapped differently.

We had the Dyno manufacturers log in for this car and study the ramp rates and as you can see from the tuned run the car hugely improved and had a much nice curve on power and torque so currently apart from some guesses we have no idea why it behaved this way in stock form, also strapping is important as lots of lift on the rollers is how people get inflated figures on these styles of Dyno.

In my head i have been thinking possibly some sort of emissions nonsense? But this is speculation! I have another A35 coming in in a couple of weeks so i can compare.

Many thanks
