Will remapping damage the engine?
How do you tune an engine - especially tuning Diesel Engines With Remaps and Turbo Upgrades
So this is a guide to remapping a car particularly remapping a diesel car. Via ecu remapping you can
remap the engine and revise the way it uses air and fuel to make more power.
With a diesel car remapping and ecu remaps, with chip tuning and piggy back tuning boxes make so much sense. Will it damage a car? Why should you do a diesel remap? What is engine remapping and how do you choose a good ecu remap.

I’ve driven turbo diesels for over twenty years and have always let the oil get round for thirty seconds before driving off and the same when stopping let the turbo spool down while it still has an oil supply rather than switching the engine off while the turbo is still spooled up and the oil supply is cut off, not had a turbo problem with any vehicle even at very high mileages.
10 seconds is enough when when you start the car up because of modern synthetic oils. Any longer than that and you're only letting it run cold for no reason and killing it like that. The sooner you put some load on the engine after those couple of seconds to start warming it up, the better it is for longevity.
Thank you, you give very good advice and information cheers
All of this sounds very good and interesting. You have single handedly convinced me to now go talk to a tuner for my Amarok (in Sydney).
Thanks for the quality info mate, Cheers
Glad I could help! Thanks for the support and your kind words, let me know how you get on and what your thoughts are, I'm sure it will blow you away.
Got a vw TDI 2.0 tune from an english company, definetly very good value for the performance increase. I hade a choice to buy a, user upload and download OBD install device, or have a tech do it. Both options have their advantages. I had a tech do it based on his reputation. You didn't really discuss these two different options. But in the end your getting the same predetermined tune file that's been made on the dyno with the same model car, or at least the same model engine and ECU. The tech said he'd be happy to do adjustments to the map if required. Which along with the guarentee offered is the reason you would have a tech do it over the do it yourself mapping device. When I have the DSG tune installed I will have him look at the turbo map. So it's good advice your offering about the cool down times for it. I hadn't considered that. Thanks for the video. DSG remapping vid? maybe.
I will start researching the DSG and mapping them for you so there will be a video soonish coming out on that.
Thanks for taking the time to make these videos. I just bought my first diesel car and am considering some changes. What would you think, good safe figures would be for a 2016 Scorocco TDI 2.0?
The reason I ask is I have fear of the mapper maxing it out and causing reliability issues.
Have you had any experiences from Toyota Hilux remapping? Great explanation by the way!
I’m seriously considering getting my Karoq 1.6 TDI remapped but I’m concerned about the longevity of the DQ200 7-speed dry DSG box, I used to drive a Fabia vRS which had the DQ200 and many people were mapping them past the factory spec and they were fine but I just wondered if you had some insightful knowledge about how to care for a DSG box when mapping the car since it’d make more torque than a petrol would.
I’m looking at getting a stage 2 map on my 3.0 v6 tdi Mercedes C320. The remap company near me has said all I need is the DPF removed for the map (the car doesn’t have a DPF from factory). Do I need an uprated intercooler or do you think stock one is fine?
Im thinking about getting a chio from TDI Tuning for a bmw 116d 1.5... they say it should make 150hp, stock is 116... my local tunner wants double the price of the chip and should make arround 140... what should I got for?
I’m currently considering doing a stage 1 ECU remap, carbon cleaning on my 2014 Audi A6 2.0 TDI s line auto, my going is to make the car run smoother and revive the car after buying it at 80k miles but I’m not sure about how that will effect the reliability of the car? Am I right
I also have a 2.0l TDI VW. It's in a Mk5 Golf Estate. I'm planning to lift it and wondered if you could make a video about how to find cross compatible springs from other vehicles and how to know how much height the vehicle gains from them. How do you tell what stiffness and size your springs are?
I will be covering suspension upgrades in much more detail for these in a future video so please stay tuned. and thanks for supporting my little channel.
Good information 👍
Would it be a benefit given my vauxhall mokka 1.7 tdi remapping
Definitely, The 128hp version of this engine (With the E87 ECU) will see 40hp and 70lbft more torque on a performance map, but get a performance panel filter. You should also see better fuel economy but this will depend much on your driving style and how you use all that extra power.
I have an A220d would remapping it help
Can plug in hybrid cars be remapped?
i have a 184bhp diesel with a tune its about 240bhp difference was night and day havent had a problem with it at all it is a bit thirsty tho
lol It's only thirsty because you use the power, but I'd do the same. That's quite a decent power bump you have there. Was it just a remap or did you have other mods done too?
@@torquecars it was just a remap i think its 220bhp not 240 i forget.
You own a GTD Golf, don’t you?
I have just bought a citroen 2012 Ds3 E-hdi 1.6 litre diesel turbo, and been thinking of getting it remapped, would I gain much power from it, and would it mess up with all the sensors and light up on the dash board? Cheers
The 90hp will map to around 120hp and the 110 should see around 135 on a map, you shouldn't have any issues as long as the car is well maintained and looked after.
@@torquecars..okay thankyou
I had a kess remap on my 150hp tdi. Not sure of what the hp is now but im told it should be at least 180 to 190hp. It has made a noticeable difference 0 to 60 and lift at higher speeds for overtaking. Im wondering does my DSG gearbox give the tuning an advantage or not ?
The gearing ratios are better on most DSG boxes, but they do limit the amount of torque you can output in some cases, but most mappers will take this into account and work round it.
Did you get the DSG mapped as well?
@@torquecars no I didn't get the dsg mapped. The guy who did the remap said that my 150hp would gain around 40hp. It's a mark 7 golf estate. He said he wouldn't recommend any more that this as in his opinion this was a safe remap which doesn't put too much unnecessary strain on component parts. I did ask about the DSG system, as i was concerned as he did say there would be extra torque but again he said this would be a reasonable amount as he always recommends not pushing the limits too much. Again he said the dsg system could handle the extra torque and hp. I have to say that the car is driving much better when I ask for power, although I normally drive easy on the roads as here in the UK I don't need another speeding ticket. I have noticed that my mpg on economy drive appears to have increased. I will know by how much soon as I filled the tank to the neck and will calculate that but it could be around 8% better consumption. Certainly I have been hitting some impressive mpg figures on longer drives.
Is it worth remapping a 2009 Fiesta 1.4 diesel? 68bhp. Or would it just turn it into a fuel guzzler?
I've just done my astra 1.3 diesel ,has made such a difference,it's actually better on fuel funny enough
Will mapping my car resolve the orange EM light issue, keeps coming on then goes out.
2017 GLC 2.2D
Thanks
An em light usually indicates a fault or problem and in most cases a remap will not fix that underlying issue. In some cases (low boost - altering the turbo wastegate profile) may avoid the problem or make the car more inclined to ignore the fault. It could just be a malfunctioning sensor or loose wire.

I have a 2015 A3 2.0 TDI sportback that I've mapped from 150hp to 215hp and about 445Nm. Only mapping, no extra parts. Is there anything else I could do to get some more power and still keep the car in a safe zone? It's a manual gear box. Also do you know the safe rev ranges for the gears? 😊
Hi Buddy, it sounds like you've taken that one to the max already. Turbo and fuel upgrades are next but this will cost quite a bit more than the remap. For performance and a spirited drive I would change gear about 4000 to 4500 RPM - the engine is starting to run out of puff and it puts the car in the power zone in the next gear, after a remap it still pulls through the 5000 region, but I don't feel it worth exploiting this part too much.
Is the air intake or filter upgraded, you may well be getting a restriction on the stock setup at these power levels, but not by much if I'm honest.
Intercooler mods will help you avoid heatsoak but if you only do shortish burst of high rpm driving that would be a waste of money.
@@torquecars thanks for the answers! Great channel!👍😊
Cheers buddy, thanks for the support and encouragement.
@@torquecarsi have 2016 a4 2.0TDI , when “safe zone” is a question to be answered , what in your opinion is the safest zone for a manual which wont hurt the clutch and other components? My car is 136hp the max would be 195ish which in my opinion is too much.. What are your thoughts? Cheers!
You have a 150 mapped to 198bhp and 395 ft lbs. Like pretty much every other map out there, as for the dyno sheet, you verified that independently on a PROPPER rolling g Road??
Mines the same anyways, oil oil oil oil oil oil oil oil oil. Service it like he'll, I do 9000 miles max but 7000 avg between services with gtx magnates, turbo will eat its seals, then the housing and finally the shaft if you don't.
Mapped cars = must service as often as you can.
Turbos DO NOT Need that cool down period, there designed from day one to operate at there (lets say) 1 bar of boost level, continuously, a good map (like the manufactures) will control EGT's and infect most now do.
For every 1c above target IAT, timing is retarded, to control EGT
at 1440F Derate signals are sent to the ECU to maintain the EGT at the max the turbo can take and at 1560F ECU will enter limp and power down modes until temperatures decrease
Lets be clear, turbos are designed to OPERATE CONTINUOUSLY at full boost and max EGT, all the start stop start stop, spool up heat up, cool down and crack types of daily driving are what FUCK a turbo over.
I just wish most aftermarket mappers would actually pay proper attention to EGT control and management, I still see too many maps with aggressive peaks and settings especially at low rpms.
They seem more focused on getting a peak power spike as early on in the power band, and I guess in some engines this may be ok but in most (European engines especially) it can cause problems especially when you factor in the daily drive and average drivers habits when it comes to maintenance and care.
It really pays to use a mapper who knows your engine well, rather than an off the shelf map tweaker, or inexperienced reseller. Some ECU's like the Bosch ones are pretty good at protecting the engine from a bad map, others are not.
Most of the failed turbos I've seen are actually through excessive wear rather than metal fatigue or failure and I would blame the oils ability to lubricate the turbo properly. It is probably more accurate to say a turbo engine needs oil at the correct temperature and grade with most of the cooking going on inside the turbo itself in many cases so it's the oil that needs a chance to cool down more than the turbo.
If people actually changed oil frequently and used premium oil blends and the correct grades and formulations then turbochargers will last much longer and you have a wider tolerance for driving the turbo harder.
However in the real world I still strongly advocate that a turbo has a chance to "run down" even if only at low boost - as you say to ensure reliability but I know some people out there are not worried about reliability.
@@torquecars I have a 2.0 TDI Audi A3, 2006 - Mapped at 12,000 Miles [Before i got it] by dark side developments, a full main dealer service history, something ive maintained.
The only thing under the hood that is not new is the Turbo itself, and 4 injectors, an injector failed in the open position at speed and it absoloutly destroyed the thing, luckily it was all on the hot side.
Ive had the car about 5 years now, and my only complaint about the map, is its dead at low RPM but at 1500 rpm, meaningful boost is available and she pulls like a freight train, and murders her newer siblings :), shes also good for 155mph not the 127mph Audi intended.
Right now she has 187,143 miles on the clock, everything else (more or less everything else) is factory, some parts have been changed for performance reasons, but all the OE stuff is as it came from the factory.
She left said factory with 138 Bhp and 295 Ft Lbs (i might be mistaken) 4 months ago on her last ever dyno trip after the new turbo she laid down 199 Bhp and 405 Ft Lbs.
This is the 3rd mapped car ive owned, and i can say hand on heart, there amazing, and ive never experianced a bad tune or bad company, i did lots of research first mind, but still, good tuners are everywhere. You got a diesel in the UK, seriously pick up the phone and call Darkside there products are amazing and so is there work
So the car above has finally gone to the scrap yard, she went in at 308,291 miles, with a failed crankshaft.
Thats as near as makes no diffrence 300,000 miles mapped, full service history, and zero problems, i think ill rest my case for a well mapped car :)
