DMS Remap for 997 C2S

[James996]

Just wondering if anyone had used DMS to remap a 997C2S

Thinking of getting it done next month and was wondering about the pros and cons - they claim it will go from 355 BHP and 295 lb/ft to 379 BHP and 319 lb/ft

Was also wondering what it lowers 0-60 times to if ayone knows?

They've quoted me £799inc vat and will come round to fit it at my place of work/home

Any info greatly appreciated

Thanks

James

Have been considering this seriously myself. Met the DMS guys at the last VMax and they really seemed to know what they were doing, plus lots of positive feedback from others on here.

If you do it, I'd be very interested to know how you get on and whether its worth doing.

Cheers.

Spend your money on driver training IMO - a remap for a non-turbo car is not going to make any difference for 90% of your daily driving.

[James996]

I didn't ask what I should spend my money on - I asked what people thought to the DMS remap! I already have some driver training coming up.... don't take that the wrong way )

Has anyone got any DMS comments please?

second the comments above. Electronic tuning on non-turbo cars is pointless.

I usually find people who say this haven't had any tuning done and are just going on what everybody else says.

I've tuned a few N/A car and been pleased with the results and would do them all again. If it’s tuned right you’ll notice a more flexible engine and better MPG.

Also notice we have the old clique, “get driver training”, but to be honest I can drive fast enough on the road to scare myself to death and safe enough to be able to read the road, mind you, I have done a bit of reading on the subject and had a few runs under instruction. Driver training doesn’t help when you just need more shove.

If that is the case, why don't Porsche tune it like this as standard?

Sounds ike you badly need driver training!!!

Possibly something to do with EU legislation - drive by regs, and emmisions......
As for DMS, had nothing but great results from them - all turbo's tho'. They're a good bunch of guys, who, IIRC will give you your money back if you're not completely satified. So it's a no-lose situation.

Porsche tune for all eventualities and more significantly, all fuels.

So there is room to make the timing more agressive and other parameters to take advantage of high octane fuel and the less extreme temperatures and altitudes - say in the UK.

So in terms of a remap only IMO all that can be done is to increase the effectiveness of the engine (e.g. more power) at the cost of narrowing the window in which the engine will operate.

Though I agree the gains on a NA engine would be questionable - the owner may be happy as he/she drives away and 'feels' the car has a better mid range etc.......but I've never seen a set of like for like before and after performance figures for these NA remaps - I think this is because they don't make any difference.

Can't see EU legislation causing you to get less mpg (and presumably more C02) than you could otherwise achieve....

I don't doubt they are a good bunch of guys, but presumably the warranty situation is still somewhat unknown?

I had a live re-map done on a n/a 993. The tuner's expensive dyno, and my own very cheap one (ie my arse)concurred on a real and noticeable increase in mid-range torque and top end power. In case you think I can only feel it because I want to - the unusually healthy engine was also commented on, unprompted by me, by John Lyon - who has driven a 993 or two, when I was wisely spending my money on driver training.

How conceited. First no answer to the OP's question, second the assumption that he's no good, and third that no matter how much driver training you have when you get to a straight bit of road the accelerator pedal still only goes as far as the stop.

Exactly!

Well put sir

ah ha yes - with the 3.6 air cooled engine Porsche left 'a lot on the table' as it were - up for grabs.
I've done the same on all my NA 993's - good results.

However with the watercooled flat 6's I've been told my a couple of reputable tuners there's nothing really up for grabs from just a remap - e.g. the 997 3.6 is already over 90bhp per litre.....

edit: I should add though - I've never done it on a watercooled NA. I did some research when I had a 996 and in the end decided it wasn't worth it...

i would have thought that if it increases the torque and bhp figures and it has lots of grip (which 997s do) then it will increase the 0-60 time. the powerkit boosts it to 375bhp and the 0-60 time goes down from 4.8 to 4.6 secs so i would have thought it will be quite similar.

[anissut]

Porsche charge over £8k for the powerkit to take the 997S to 380bhp. Do you honestly think a remap from DMS will give anywhere near 375bhp? I highly doubt it. Yes, it may improved midrange, improve throttle response and maybe improve fuel consumption but even though Porsche charge ludicrous prices the £8k needed to get 0.2 secs improvement to 60mph and then 2-3 seconds quicker to 125 mph clearly needs a lot more than a remap.

I owned a BMW M3 CSL and I went up against another CSL which had been remapped. There was the most miniscule difference in it when we floored it alongside each other. That miniscule difference might not even have had anything to do with the remap but maybe him being on the throttle quicker or other variables. I would love to be convinced by a £750 remap that can give 20-25bhp but unfortunately I'm not.

I'd guess the M3 CSL engine is more Maxed out than the Porsche lump, might be something to do with it?

Yes true the CSL engine is right on its limits, no doubt about that, hence remaps maybe not being worthwhile but it still doesn't explain why Porsche charge £8000 for 25bhp and DMS charge £750 for apparently the same gains.

[Bumcrack]

What did you think to the CSL, I thought it just missed the mark for involvement, quick though?
