Polo GTI APR ECU Upgrade

[Corey_R]

When you say you have spoken to a few Audi mechanics who all know how APR program switching works? Do you mean, that they know how to perform it via the cruise control? Or do you mean they know how to read the ECU with a computer to see whether it's been flashed or not?

Because whilst how to switch via cruise control is fairly common knowledge, the security lockout takes care of that. Unless you first enter a 4 digit pin, the cruise control switching doesn't function, leaving no hint that a tune is there (if you've put it back to stock obviously).


But yeah. I'm in two minds about this dishonesty towards the dealers anyway. I kinda figure, if you're picking an aftermarket tuning company that you think you're going to have engine/drivetrain issues after using, then you're probably picking the wrong damn tuning company! lol

We then get onto the issue of, are you going to change anything else? Intake filter? Entire intake? Exhaust? People often go on to change one ot these items or more. What's the obsession with attempting to hide the ECU if you're got aftermarket hardware in plain sight?

Brilliant point corey. I contacted my dealer and while they weren't against tuning they did suggest to maybe wait a bit seeing as it's a new model and maybe until the warranty runs out too. More than happy for suspension mods etc

[Corey_R]

Well it's not like suspension mods have ever caused warranty issues (lol, they have, just in case people didn't get the sarcasm).

I think that if you were serious about getting your ECU updated, if you DID wait until the warranty had finished, you'd be KICKING YOURSELF once you did get it done... for waiting so long. I can't believe I waited 1500km

I'm confused about the security lockout... If someone was looking to see if the APR was installed and it requested a security code, wouldn't that imply its been tuned or is the security stock as well?

[Corey_R]

It doesn't request the security code... otherwise, as you mentioned, it'd be pointless!

Basically, APR ECU with switching, put it in stock mode, enable the security switch, and then there is no way to tell that the car has been flashed*. It's just like getting in any other normal stock car. No different lights, beeps, anything.

So if the system is locked, you turn on the ignition (but not turn on the engine).
Move the cruise control to on (flick it off then on if it was already on).
Press the "set" button the number of time as your first digit of your code (i.e. four times for 4)
Flick the cruise control off and then back on, enter the next digit and repeat.
Once your fourth digit is entered and you've flicked the cruise control off, the Check Engine Light and EPC light will alternate flashing.

From memory you turn the ignition off again and then do the switching process, which is just putting the ignition on, turning on cruise control, and then holding down the set button. After 5 seconds the CEL will flash once per second indicating you've selected program one, another 5 seconds and it'll flash twice per second, indicating program two is selected etc.


* When talking to a local ECU tuner who writes code themselves (I don't know if they want to be named or not) they indicated that they could interogate an ECU and determine that "someones" flash was there. There'd basically be encrypted data in areas of the memory where there should be data (or something to that effect - please don't flame me, I'm not an ECU coder myself!). But when we discussed the interactions he's had with dealers he admitted that it wasn't something the dealers would do. Whether they don't know HOW to do it or whether it's not worth their time or what, I don't know.

Yes that is correct. There is Flash counters and some companies will tell you that they reset the flash counter during their flash but there is more than one flash counter, in fact on some of the VAG models there is a flash counter embedded in the instrument cluster.

Alot of the "big tuning" companies today that can only offer generic flashes will attempt to gain customers by fooling them into believing there flashes are not detectable - That is just another line of crap. Those guys don't even tune cars as they work from a library of files they got from somewhere.

Don't be fooled! If a car was tuned it can be detected if need be.

[Corey_R]

Well, forgive me if I don't take the word of a newbie with 3 posts over a small competitor to the "big tuning companies" who does write their own ECU code and says that the counters can be set to their preflash values. But as I've said before, if you guys are that worried about concealing things from your dealers, then maybe tuning a brand new car is not really something you should be doing.

Sorry? What does post count matter? A newbie to a forum is not a newbie to tuning or how tuning works.

I am not worried about concealing things from dealers at all, I do not try to lure customers by brainwashing them into a point that a dealer cannot detect their flash as that is incorrect.

For anybody tuning company that actually writes their own SW will understand what I am talking about regarding the "Big Tuning" companies.

What Corey is saying is, until 3 days ago we hadn't heard of Customspooling in Australia. Building some trust with potential customers, using your name once in a while etc goes a long way to achieving that.

There is a great video showing how the security code works on the APR website. Corey's right. Unless the dealer guessed that you had an APR ECU upgrade AND guessed your security code, they wouldn't be able to detect it that way. Maybe via some secret flash counter that hadn't been reset, if what CustomSpooling suggests is accurate.

Here's why I care. I didn't get my car through my local dealer (there is only one in my neck if the woods), as they wouldn't be able to provide me one until next year. So they're already peeved at me. They're irrational, I know, but these guys already threatened to not even service the car if I got it from somewhere else. (I often wonder what they're service department would think of those sales tactics.)

So I could just imagine the discussion I would have to have with them about the role of the ECU upgrade, when the fact is it would very rarely have been turned on, because more often than not, I drive with respect to economy, instead of performance.

In other words, it would be nice to have the option of improved performance at times, but not have those rare moments cloud any discussion of warranty issues with a dealer.
