In the morning
Met Paul and his colleagues at eurocharged / S2Smart in Watford today to get my 2010 C350CDI (231ps) fettled. The workshop is based in a small, light industrial park, between Rickmansworth and Watford. A couple of other garages are based there too, ProAlfa and CKS. I was greeted by a whole gaggle of Smart cars, a few coupes, 4-4 and plenty of 4-2s.
After pleasantries were exchanged, the car was checked over with a Star diagnostic machine, some of the wheel speed sensors registering an error 3k miles ago, probably originating from when the pads and discs were changed. I opted for a before and after dyno run, as I like to see some figures. I waited for a Golf to be seen to - the owner was very pleased with the result.
Dyno time
My car was reversed onto the dyno and strapped down. A reading was taken before any changes were made to get a baseline figure. The result was 255bhp and 444llb ft or 600Nm, which was quite a surprise for me, especially the torque result, as these numbers are more akin to the facelift 350CDI. I've been around long enough to know figures from dynos can vary on how they are operated and even how tight the car is tied down will influence the numbers, but for my purposes it'll give a good indication of the percentage difference.
ECU was removed from the car, lid removed and the ecu connected to the laptop via a box of tricks to read the existing map. The maps were identified and changes made and the checksum recalculated before being written back to the ecu. After this was done, the ecu was reconnected and the car started. Another power run was made and the figures were 293 bhp and 538llb ft (730Nm). So the car gained 15% power and more importantly 21% torque.
What is the car like to drive now ?
It felt a bit lacking before - now it feels much keener. It is still smooth to drive. Mid-throttle response is stronger, but not twitchy or oversensitive. My drive back home was in heavy traffic, so I didn't really get much chance to test it.
I am a little wary of DPF issues and asked Paul to check the DPF using Star, which showed it had 3g of soot, so it appears to be working fine. I have been filling the car with Shell Vpower diesel as it is supposed to burn with less soot, so I'll keep using that.
Fuel consumption-wise
I've only driven 50miles since the remap so much too early to come to any conclusions, but it doesn't seem any worse and The car can accelerate harder in higher gears than before, without changing down, so I expect the mpg to improve.
