Hello guys, I have changed the cam and followers, fitted  an ARL turbo, deleted the Egr on my VRS. I haven’t done the remap yet. My check engine light has come on, which is to be expected…. The new cam and followers jave made the engine more silent, but at. The same time I hear a faint knocking from time to time, and rougher cold starts. Maybe tge cam needs to settle in a bit?  The car is absolutely gutless now. I can hear the turbo whistle more then it should, but I am getting no power… Is this to be expected on a stock map? I was hoping to get a little less power and lag, but this is too much… It’s almost as if the car is in safe mode and has no turbo… Thank you!

Can't happen, won't happen at the same time from a bigger turbo and a stock map; the car will drive like it has a boost leak. Or maybe it even does? Do you have an increase in black smoke?

It sounds like the car is stuck in limp mode, you should read the codes and reset the ECU first. Did you reset the injector lash after changing the cam?

No, the cam and the followers were changed, as well as injector seals… There is no black smoke at idle..

Who said "at idle"? I certainly didn't.

Guys, can I check whether imjector lash is good in vcds?

Nope.

But if it’s not good, wouldn’t I be able to see it as bad readings? I have just put a new engine seal cover… Can I reuse it after setting it up properly, if it isn’t good? 

Just checked with my mechanic. He did set up injectors, he said, of course…. But why limp mode? Maybe because there is no Egr and there is a bigger turbo? The car is a proper SDI now 😟

If you haven't overtightened it then you can reuse it.

Get.

 

The.

 

Codes.

 

Read.

Yes. Something else is a miss… 130 vs 150hp turbo. There shouldn’t be an issue….

Which is why getting the codes read is such a good place to start ……

Well guys, no codes, SDI power thumping and misfire, brand new cam, lifters, injector seals….. Any ideas? Cam or injectors related? At idle it sounds good…

😵‍💫😱

How can there be no codes, you've deleted the EGR but it hasn't been mapped?

Just that one code Egr related, but no other codes… But I have a Delphi disgnostics on my laptop, no vcds… No other codes were read, even thoug I am driving a broken SDI ag the moment.. What do you think of the misfire, and severe loss of power, vam or injectors related? The car idles fine… 

😔😱

How did you set the stop screw on the turbo actuator linkage?

I haven’t touched anything.The turbo was taken from a friend’s Fabia Vrs remapped at 190hp…

FFS; we already told you you're running a wrong map for a big turbo!

The tuner told me no way should it run so gutless… Going to a 20hp bugger turbo shouldn’t be so big of a deal….

Ok, one question. Who's wallet is connected to you believing it should run OK with the big turbo; his or mine?

Believe me, I don’t know who to believe. As I said, the car drives like an SDI and the tuner told me the difference between the two turbos being small, there shouldn’t be any problem, some turbo lag yes…. But as you said good diag. That Delphi crap that I have is crap.

Android phone, screen or dash holder, Torque app, Bluetooth OBD2 - does it show any boost when driving - YES or NO. Example is from a 1.2TSI Polo so boost will not be same. Baseline data will allow people to review rather than assuming the typed word which does not always contain full, applicable or correct information.

Not sure I'd trust any of those figures, because I'm seeing the alternator overcharging enough to boil the battery and fry the electronics, and the radiator overcooling enough to kill the fuel consumption if those values are accurate.
