pulley and tune

[Dieselman]

SPX don't think you really understand the point of a dyno, if everyone thought like you, the dyno operators and tuners may as well pack up and go home, we have a lot of guys on here that are just trying to help, I don't know why you are being disrespectful, I for one don't care for 0-60 times, for the reasons that have already been pointed out, we have a bigger picture here, it's about performance drivability, mph, torque and many other factors.

It's no wonder persons get annoyed with this forum and sit in the back ground, seems every other thread someone is out either to disagree for the sake of it or to be on some sort of wind up, not why I come here, information and advice is what the OP is after you have turned it into another pointless thread. Clearly we are preaching to the unconverted I get that. Just remember at least what section of the forum that you are posting in and show a little respect to others that possibly know a bit more than you.

That is one of the worst posts I have ever read on this forum.
Did you do English language at school?

Put your ego back in it's box and read what SPX is telling you.

A stopwatch will pick up any performance improvement using timed acceleration runs, a wheel dyno isn't reliable enough to do that.

 

[Dieselman]

Lol, yes Vmax is better for sure! Ricky we should tell Craig to drop the Vbox and fancy timing equipment and just spend 20 pounds on a stopwatch!

What do you think the timing gear is...???

It's a stopwatch that reads the time taken to pass two known points then do some maths to spit out a velocity figure.

FFS...the lack of knowledge on this forum beggars belief sometimes.

Sir I don't think you have driven a supercharged AMG Mercedes let alone one that's had a pulley and ECU,

Ego-tastic...

He's got a C32.....!!

To get this thread back on track.

The O/p should do some timed runs in both directions to check if he has any improvement with the remap and pulley.

Automatic cars are generally very good at standing start time replications, but if he can't achieve that pick a flat road and run from say 10mph at a set point to another set point and time it.

I would have thought all the "tuners" on here that go to the Pod or V-Max would have understood the theory of what they are doing when the run "Timed Runs"...It's not difficult to understand...

They are called "Timed Runs" for a reason...

0-60's are pointless Paul, don't ya know!

So many experts........

0-60 timing is probably just as inaccurate a guide as you Guys think a dyno is.....

Let the OP decide and then everyone move on.

You are normally the first to pint out that there is no science and people just bolt things on, I have read posts where you ask did people check what the EGT was post remap.

If the OP has an issue the first thing is to see what's happening not how fast it is.

The software he is using includes the capability to data log and that should be the first step, understanding what the map is commanding vs what is being delivered. Blindly taking full WOT runs is not what should be suggested.

Sorry if I am being thick here but are you saying you have not noticed any difference after fitting the pulley to before the pulley or that with the pulley fitted you don't notice a difference between the stock and performance settings?

no I did notice a small performance difference after fitting the pulley, it was the next day when I got my file back from eurocharged and I flashed the car drove it and I couldn't tell any difference , so I decided to reflash the factory flash to see if they had been mixed up and it feels exactly the same . I now have the performance map flashed on again but there definitely isn't a massive difference between them ,and from other peoples posts after the pulley tune upgrade I should definitely be able to feel the difference

Gaz, what was the outcome of your intercooler? Did you replace it after you found gunk under the plenum covers?

FFS this is not hard is it car has had a pulley change not stated whether overdrive or underdrive Can't tell difference between standard map and remap (no surprises there either)

Two questions

1. Could the OP tell the power increase when the pulley was changed?
2. What was promised in power gains from the performance remap after the pulley change?

Totally agree with DM though dyno at this stage is a waste of money for £5.99 THIS will identify any performance issues.

If there is still a problem after that I'd start looking at what map files have been altered and the parameters before and after the change

Something not right here somewhere

This typifies my thoughts exactly.

Certain forum members such as yourself never want to give in and accept that other people's opinions are correct, or correct in their estimation. Instead you continue to pursue your point in order to frustrate others.

The subject of this thread aside, then I totally agree with Billy's comment that you have just tried to ridicule. A forum is for expressing opinion yes, but importantly it is for sharing knowledge and helping like minded enthusiasts, not for forcing personal opinion.

I have to admit that whilst you seem to have some good technical advice, I tend to avoid your posts in particular as they always seem to have an ulterior motive, or you just come across as patronising.

Your final comment reference having a dig at a forum member's grammar typifies how you post, have you never considered that some people may be dyslexic, may not have been bought up with English being their primary language or may use a tablet device that tries to predict your spelling and grammar, albeit sometimes none too effectively .....

Rant over.

The O/p's issue was that he couldn't feel any difference.

SPX, correctly said getting some hard data by timing a few runs was the best thing to do as it removed the "Butt Dyno" issue.

He is driving the car so a few more acceleration tests won't make any difference.

It all strikes me that the tuning add-ons have been done in an ad hock way and the super-dooper custom tuner hasn't really got a clue.

From my understanding of this thread the question was 'has my new map loaded ' rather than how much more power it's making . Spx and my self was really just suggesting ways to quickly determine if there was any gains quickly with out using a dyno . It sounds to me like the new file is not loading .

I've just done headers and primary cat delete , and (even though it's not been tuned for them yet) I can feel a huge difference higher up the rev range but at the expense of a bit of bottom end torque . I don't need a dyno to tell me I've picked up more power , but I do to qualify the actual hp gains and set up fuelling and the other parameter .

Check to see if datalogging is enabled on your version of Euroflash, it is the lower icon on the left hand side. If it's not ask them to enable it for you, then log one run in stock and one in performance. Email those to Eurocharged and they can adjust or advise as necassary.

To get this thread back on track.

The O/p should do some timed runs in both directions to check if he has any improvement with the remap and pulley. Yep you are so right.

Automatic cars are generally very good generalisation - like an automatic Mondeo will launch as consistently as a supercharged AMG? at standing start time replications, but if he can't achieve that pick a flat road Generalisation - is it a flat road by feel, or maybe because it looks fairly flat, or does he need to get a level beam to check?and run from say 10mph at a set point to another set point and time it.That seems so accurate, so whilst launching the car on a flat road, he is expected to start the stopwatch bang on 10mph, I assume this is whilst looking at the speedo and not whilst keeping his eyes on the road?

I would have thought all the "tuners" on here that go to the Pod or V-Max would have understood the theory of what they are doing when the run "Timed Runs"...It's not difficult to understand...Most Tuners use these events to back up the tuning and modifications they have carried out after quantifying the gains on their dynamometers of choice. The timing equipment used at the events is of a much superior quality to a stopwatch and uses beams to trap start / stop / mph consistently time after time due to them being in fixed and calculated positions. VMax held at Bruntingthorpe for example, is ever so slightly uphill on the back straight, so the same car covering the same distance at another location with all other variables comparable may run a different time / top speed. Accuracy and consistency being the key.

They are called "Timed Runs" for a reason...

So this is what happens when threads get out of hand

Sometimes there may be no right or wrong, just opinion.......

Once again you seem to be confusing the issue.

The O/p needs to know whether his car is performing differently with the tuning mods, or not.

I'll keep it simple:

If the O/p can't launch his car reliably pick a seemingly flat road and run three runs from a steady 10mph to 60mph.
Either hold the stopwatch in one hand, or have a passenger operate the stopwatch...
Press the START button and mash the accelerator at the same time. When the speedo sweeps past the 60mph marker, press the stop button.

Turn the car round and perform the same in the opposite direction.

Do three runs in each direction and average the readings.

Is that simple enough?

I have the dynolicious app on my phone so will try some 0-60's when I get the car back from some bodywork being done for comparisons if you like. I remember benzedup doing some runs post pulley and map and he was getting 4.6's and 7's I think. Which were in damp conditions but he has the benefit of an aftermarket LSD....
