3.0 TDI 218hp (CRTE) ECU remap to 328hp

[antivirus]

I've been looking around for a remap for my A7 3.0 TDI 218hp (CRTE) and have found that the the 3.0 TDI 218hp (CRTE) is a detuned 272hp (CRTD) or so I've been told. I have searched through the Audi engine parts catalog and all the parts for the 218hp CRTE engine are the exact same parts for the 272hp CRTD engine. So can anyone tell me what is actually different other than the software?

They have remapped the 272hp engine to 328hp and say the same remap works perfectly on the 218hp engine as it is just a detuned engine, surely this can't be true? Thats an increase of over 100hp for about 700 euros!

Jeepers, it's down to £499.. bargain if it can achieve that.
The 218ps is the Ultra that we have.
I'm not sure how this would affect the engine and the emissions side of things, how does that work with the TAX bands or does it not affect it?
Insurance wise, given the huge percentage increase in power, you'd probably be looking at a big jump in cost, even with a specialist insurer.

Interested in how you get on

A lot of manufacturers are going down the road of detuned ECU's to save money on build and parts stocks. It works out cheaper for them to design one engine and then present it in different levels of tune.
I would go for the remap it will transform the car.

Thanks for the replies guy. I'm going to see if I can find out if there is any differences between the 2 engines but so far it does seem like it is just a detuned engine. I'm off on holiday for a couple of weeks so I'll see if I can find out any more.

As for the insurance hike, I haven't contacted them but I'm guessing its going to be an extra 300 euros for me. Not bad for the power jump

Hi, I thought I would post up and let you know how I got on. I ended up buying the remap kit and installed it myself. Took me about 30 minutes to do with setting up the software on my PC, backing up the original map and uploading the tuned map. Holy ****! it's like I've been given a completely different car! Going from 218hp up to 328hp is very very obvious no nee for a rolling road test. This is easily the best 600 euros I've ever spent :-D

If you've been on the fence do yourself a favor and get the remap, you will not be disappointed

I would be very surprised if there are no hardware difference between the low and high power engines, factory does not just tune with a remap, even a 20-30 Bhp increase warrants a new bottom end, different turbocharger and a completely different map ! The reason the car feels different is due to torque increase, Bhp is not that relevant with diesel engines. I bet if you took it for a rolling road session you will find that the increase is about half what they quoted !

Hi Chris I looked into this for somebody else and I could find no difference in hardware between the 218 and 272 engine. Same turbo. Pistons, crank, injectors, pump etc.

I thought there would be some differences but there isn't. I've searched and search and couldn't find anything, it is just a detuned engine. There's a lot of reasons why Audi would detune this engine. Audi do not make individual parts for every single different configuration of engine setups, think about the million it would cost to just develop and produce all those different parts. Then think about the cost designing, building, testing each and every different engine configuration, think about the amount of different assembly lines etc etc etc... The cost would sky rocket.

It's much easier to develop the one engine in different states of tune and sell them at different prices.

As for a rolling road, why? I'm not interested in those numbers, I'm interested in the feel of the car after the remap. If you need a rolling road to tell the difference then what ever remap you're using is not worth what ever you paid for it

As a test I did a 0-100km time check and it was 5.5sec, if it was 328hp I would expect it to be closer to 5sec but considering the run I did before the remap was 6.8sec. I'm very happy with the results :-D

Hi Karl, I stand to be corrected however is very, very unusual for a manufacturer to use one size fits all type of engine especially as the tuners have unlocked the tricore ecu long time ago ! Think about theory they loose in 10 years time when these cars became available in breakers and everyone can use parts for both models. Whilst not unusual, the way that factory tunes new engines is a big money making scheme and the more diversity the greater the chance folk will buy replacement parts at dealer or specialist diamantlers !

 

[desertstorm]

I think the manufacturers are looking at the the short term development and manufacturing costs more than the sale of spares which they aren't going to sell many of anyway on an engine.The reduced cost of manufacturing, parts counts, development costs etc works towards making it cheaper to manufacture. The same reason they seem to use a modular approach to the new engines and cars making it easier and cheaper to manufacture. I think BMW do a lot of this on there normal 1.6 ,2.0 petrol and diesel engines.

 

[adamss24]

It could be that way, definitely the end user will benefit from lower maintenance costs due to high availability of parts...

 

[adamss24]

I will be looking for one to take on a test drive due to low insurance costs on the lower power model however o am not that fond of the new diesel engines, had 2 audi's with the 3.0 tdi engine in (a 2010 a5 and a 2012 a6) with stretched chains ! The a5 is only 30k on the clock !

BMW normally have the same engine but use different intake manifolds to limit the power output of the lower ones.

Have you checked if the S-tronic can support such a big torque? I've read somewhere on this forum that this 218hp engine has the torque limited at 400 NM to protect the gearbox. The 272hp version has the tip-tronic gearbox, which is a torque converter one. I am also close to place an order for a brand new A4 and I am so undecided between these 2 engines: 218hp and 272hp. How about the fuel consumption after the power upgrade?

L.E: I thought the discussion was about the A4 . I've looked now and saw that the 272hp version of the A7 has the S-tronic gearbox.

 

[antivirus]

I never checked fuel consumption before the remap or even now. I fill her up about once every 3 weeks and that's been pretty much the same since I got her. The car is still running great and always puts a smile on my face

How are you getting on with the BSR PPC. Have there been any issues?

I'm trinknibg of picking up a 218PS 3.0 diesel a6 all road. I want the 272ps, but I can't find one with the toys I want. So I plan on mapping the 218 up to 272 as it appears to be the same engine.

Do this sound sensible or have I missed something?
