OK. I have not been back on the dyno so no charts..........
DMS offer a mobile service which is what I used, their HQ doesn't have a dyno for non developemnt work (ie not customers cars) anyway.
The MD of DMS doesn't like dynos because of the stresses it puts a forced induction cars under with lack of air flow and also the arguments caused by the differing results, especially with Porsche owners who are the speciality as many a Porsche differs in BHP from the factory anyway apparently.
I may or may not go back to G-Force in Aylesbury for an after run, as I already have the before and even DMS achknowledge their dyno as good - they are also Porsche specialist tuning competitors after all too.
If I do go back to G-FOrce it will be once the car has had at least a few days or a week to bed in.
OK, to the remap. Friendly chap turned up in a BMW 320D coupe on time.
Some chit chatting then left him to it for about an hour and a half. The ECU came out, was copied, remaped, then replaced. Job done.
DMS advertise their upgrade for the R170 SLK 230 Kompressor as 240BHP. When I called DMS the MD told me a minimum 28BHP increase. The guy that actually did the remap told me a realistic figure of about 35BHP increase was most likely with a dose of torque too.
The map I was given was the most they could do without crossing the "this is not advisable sir" line.
The reason I did not post earlier was so that I did not post an incorrect opinion.
I took the car for a 20 minute round trip drive after the remap on mostly national speed limit A road.
Initially, I was sceptical of any particular improvement. I acceleration through the gears from a standing start and couldn't feel any difference to be honest. I drove on, got stuck in some traffic etc etc. I then turned around for return to the office.
This time, when I pulled away hving done a a U-turn in an entrance, I could feel something a little different.
Further up the road, travelling in 5th I approached a car in front, dropped to 3rd and floored it. Normally, as odd as it seems, there is some hesitency here. A little delay before the 3rd gear acceleration kicks in. This is where my first wow came. The car just rocketed! Bang, gone, past and away.
I spoke to the tech from DMS on my return and he said what I experienced was what he would expect. The car does require some use for the map to take effect, as in it would not be completey instantaneous. I was also wary that I wanted the car to perform well, so was I imagining it?
Well, it's real! My drive home was very enjoyable. The supercharger still comes in at ~2000rpm but the car has an urgency about it from 3000rpm that was never there before and 4000-5000 rpm in 2nd gear gives a thrust that is amazing. At A road overtaking speeds, dropping to 3rd or 4th gear is so resonsive and holding the gear until near the red line gives such a burst of pace I was overtaking the cars I had planned to and having to brake hard as I approached the cars ahead I hadn't planned for yet!
I am well and trully pleased. I think the more I dirve it, forgetiing I have had this done (especially when I get a working radio tomorrow) the more the car will surprise me and impress.
Anyone else interested, please contact me in a thread or PM as I have a little reslationship with DMS and I have already mentioned some sort of deal if I can raise a few more 230K remaps through MBClub.
DMS took a card number as protection (they have dealt with some less reliable people) but it's for me to call Monday to say send me the invoice or visit me again to revert to standard/take the remap into the "that's not really advisable but we can do it sir" territory.
