Well its finally done.
I took it to Performance Engineering in cardiff, he gets amazing reviews and such a nice guy, and he knows his stuff.
Anyway I thought it was going to be a map he put on another Audi A3 8v, but he said he would never do this, he doesnt do cheap one size fits all maps.

I got there at 9am and finally left at 1:30pm so it was quite involved

My stock was 155bp and 350ftlb
I ended up on 190bh and 460ftlbs

I am not sure what people were saying about wheel spin, yes my wheel did spin once, but thats because I pushed it, and also it was raining, but went around lots of roundabouts without issue, no slidding or anything.

I had to get onto the Motorway and a lorry was coming up fast so I had to either slow down or speed up to get onto the M road... I chose to speed up obviously.... AND WOW!!

I am telling you, I thought my car had lots of torque before, but my car just flew past the lorry without any issue.

I was also on the motorway and didnt realise I was doing a stupid speed so will have to watch that.

I am very happy with the service, and £275.00 for all the work he does and the feedback he has from customers, you cant go wrong.

Pretty reasonable amount of time he spent on it for the money, the graph looks pretty good. Sounds like he put some proper effort in, so fair play.

End figures are always a little debatable not knowing the rolling road and calibration etc, but as long as you are happy with the way it drives, thats all that matters.

Only note is that it begins to drop off a little earlier than the standard map though, maybe someone more knowledgeable that me will chime in and explain that? (there may be a reason for it). The original did have a lull around 3200rpm.

Did he talk you through the curve?

What was meant by wheel spin that we spoke about prior to your mapping.

The way your torque is coming on at low rpm, your wheels will light up a lot more, what is meant by wheel spin in this scenario, is that if you try to utilise that additional power in low gears, you will get more wheel spin. To prevent it, you don't use as much throttle, therefore not utilising the additional power and at times, could even be slower than before it was mapped, in those early stages, sadly, limitations of FWD. I think though, that the diesel higher torque lower bhp helps mitigate that somewhat over a petrol engine.

No he did not mention anything about the curves, he said he was very happy with the figures and performace gains. He was in my car for hours so was happy he was just not putting a random map on my car, he said he treats every car different even though they are the same. He does full diagnostics first then base dyno performance checks, map, then dyno again, then does diagnostics again at the end, thats pretty much all I now Ha Ha

I am very happy with the performance, but if anyone knows about the curves, I would like to know as well.

On the website, this shows which dyno he has.
I dont think its a Celtic special where they like to claim a extra 20bhp out of thin air.

WEBSITE: We have one of the very best dyno’s available, Vtech VT2 - B1, very accurate and consistent which is exactly what is needed when tuning performance vehicles.

Capable of measuring over 1000 bhp / nm with a Telma eddy current brake giving us full control of how we want to test.

We can perform maximum performance sweep tests showing the maximum engine output at wheel and flywheel or simulate driving road conditions to fine tune for specific diagnostic settings.

We also use our dyno for diagnostic, enabling us to perform acute testing within a safe environment with the ease of data logging and monitoring data
 
"My stock was 155bp and 350ftlb

So you ended up with 623 Nm !!!!!!!!!!

Not sure what you mean, I've posted the print out and he told me that he got my car to 190bhp and 450 nm
Thought ftlb meant the torque. Which is 456
 
It's just a straight conversion of units - I assume he's impressed with 620Nm (also torque)
 
I still don't understand what your on about.
I don't have 620nm of torque. I have 456.

But yes very impressed. Loving the extra 35bhp

Oh right.. It was a long day yesterday especially trying to fit those stupid boot struts.

Just called Admiral who I work for and I did not have to pay anything extra for the extra 35bhp. happy dayz
 
Glad you are happy with it!
I would consider doing this to mine but don’t know if it’s wise with the mileage it has on it!
 
Im amazed absolutely you are not getting much wheel spin. My old remapped focus 2.0 tdci (up to 165bhp, and 320lbs foot torque) spun the wheels up in the wet in 4th gear. It didn't have traction control though which made it much worse.

I tried again and it spun up but only because I was in a bit of lose gravel.
Maybe its the way I drive, I dont know.
But what amazes me, when I am in 3rd and really need to get away... Damn it flies off the mark.
Before I thought it was good, but now it just feels so smooth, but really gets down and dirty when it needs to.

@ScottishA4B9 My car is on 119,000 and so far no issues, but its early days, but have not had anything happen that it different before the map.

Fair play, but yeah it makes a big difference to the rate of pick up. I seem to remember not really needing to take it out of 6th on the motorway and it still pulled pretty well. All that torque gets quite addictive. It will be interesting to see what difference it makes to the fuel economy. My S3 remap made no difference but on the focus I was getting about 10% more mpgs (properly tested, not relying just on the mpg gauge).

Yeah thats one thing I noticed, even in 6th the car still pulls really hard and has no problem overtaking,

I dont think I would ever look at my MPG, I just fill it up when I need to, but would be happy if my consuption stayed the same.

The torque is very addictive, I am sure I am using more fuel than before.
 
I work in lb/ft

love a fast diesel.

i have been offered to get my stronic mapped and engine map for £320 cash.

i used to have a fast golf tdi (270bhp) and a 220bhp fabi vrs. Not sure i want to spend the cash again though.....

tempted but not tempted
 
I was surprised at the cost vs what the guy did.
I thought he did lots of 150bhp Audi before and was just going to load up the same map, but it was very involved.

First he checked the vehicle for errors which he found 3 which were not serious, maybe old and never cleared.
Then did the first Dyno
Loaded the map - but was in my car for ages doing this.
Did the dyno again
Took it for a test drive
Then checked for errors again which they never showed up

All this took from 9:30 to about 1:30ish so he only does 2 vehicles a day, and for £275.00 I think is a great deal

Folk **** on a generic map, but theres nothing wrong with them.

Pretty similar mileage to mine then. I would have normally looked at a tuning box but they are very generic whilst your mo has been specifically for your car, which I think is better.

I don't think the map is custom built for his car, otherwise the dyno would have been ran up about 30 times and he would have used half a tank of diesel in five hours, he only mentioned it was ran up twice?, so I think its still a generic map maybe with with some adjustments to suit his car, which is what most places do these days, same as APR, Revo etc.

The tuning boxes are crude in my opinion for the reasons you mentioned, although they do do a job, and you do have the option to resell to regain some of the outlay. However for example, DTUK (the main Diesel ones) have a really crass business model (imo) regarding resales of the boxes (for example you can buy a preowned tuning box, but DTUK won't tell you what it is programmed for, and are extremely flakey if you contact them about it - so you have to send it to them for reprogramming (at a cost) even though it might even have the correct software already on it - they have the facility to record serial numbers (each box comes with one) but they don't, to obviously invoke this charge, so repeat business from the original custom. It's a pain to deal with in my experience, so I would choose an uploaded map any day.

Mine is being APR'd on Tuesday all being well, so will post the graph. I am hoping not to have that early drop off shown above though, hoping it isn't a characteristic of a diesel remap on these engines. I would have preferred a custom map, but difficult to find, and the one guy I did, didn't even hold PLI insurance for doing the work, so was a red flag from the offset.

I think if the engine isn't modified, generic maps and a few tweaks is fine for diesels, but a custom map would always be better.
 
I think you did well there mate with the price and the great torque figure.
 
@Dubjam
You keep mentioning the drop off, is there something wrong, or can anyone look at the graph and let me know if they are good figures?

I was looking at a box, but people tend to use them if their car is in warranty, but I have not heard of anyone's vehicle being wrecked by them so I can only assume they are safe, but like you said they are very crude.

No I do not think it was fully custom as I would have been there all day with multiple runs to ensure it was all tuned properly, but it was not generic either, I think your right Dubjam, he used a previous Audi 2.0 map and did a little fine tunning to suit my car as he was in my car for hours after the first Dyno.

I picked up my kids (13 & 15) yesterday and they even mentioned about how much more powerful it was as I had to pull infront of a 3 series on the motorway really quick.

I dont know why, but I feel a lot safer now because I know I can get away a lot faster than I could before, the power is there and it feels the turbo kicks in a lot faster than before.

Either way I am very happy, it feels very smooth and tons more power.

If you look at your graph, your car peaks and drops off its power earlier than the standard map, around 3300rpm, when the standard one keeps pulling till 3700 till it drops off. the power band is already extremely narrow on a diesel, so to lose some of the range, seems counter productive. I don't know enough about diesels, but if this happened on a petrol engine, if it was not 'requested' (i.e mapping for a certain scenario like a 1/4 mile), then for me it would be counter productive.

The turbo kicks in at roughly the same time as your original map looking at your map, it's just wound up more, so you get more urgency.

It dosen't really matter in the grand scheme of things tbh, diesels aren't race cars, so if you're happy with the result, then just enjoy it :)
 
Thanks for the @Dubjam
Yeah I am really happy, and am so surprised that these engines have so much more to give.
He did a small Car/Van the other day and he said they have 3 versions and all of them have the same engines but de-tuned for tax and enviroment purposes.
The one he did had 74bhp but because it was the same engine as the 184bhp he managed to get the 74bhp to 184bhp, its on his instagram, I was really surpised they would sell a van with 74bhp but then charge more for a 184bhp when you could just buy the lower BHP model and tune it to 184bhp

No Idea, how do I find out ?
I dont even know what clutch is in it.
TBH its on 119k so it may have had a new clutch and flywheel already, who knows
Click to expand...
Someone might correct me but it's my understanding the standard clutch is rated at 285 ft lb. My worry on remapping my own is it will quickly knacker a standard clutch and dmf if it's too much. My flywheel knocks on startup and I've got a bit vibration in the pedal gonna wait until new year get it done and then get a conservative remap. That's the plan anyway.

I ran with a chattering dmf for around 20k miles, that ended though when i punched the main shaft out of the end of the gearbox. Vibrations over 20k killed the gearbox

It's a priority for me after Xmas getting the Sachs dmf and clutch kit fitted, I bought the kit at a good price but my regular mechanic says he won't fit buyer supplied parts for insurance purposes. This meant there was a spanner put in the works, albeit there wasn't a literal spanner put in the works. I'll get the belt and water pump done too in the next few months. Then onto the cosmetics.

The gap between power and torque comparing stock to remapped does narrow further up the rev range, buts its still considerably more across the board. roughly 170bhp instead of 140bhp at 4600 rpm. The greatest % increase in power / torque over stock in the midrange is pretty typical of most remaps

I still got him in Torque though LOL

This is really interesting to read as I am considering a remap of my A3 150 TDI. Does anyone know (or have experience of) what the mechanical downsides are to this type of mapping - I.e. engine components wearing out faster?
 
Only clutch really , the worst VAG cars are the ones with just 20ftlb of headroom on stock clutches .
