APR ECU Version 2.0 loaded...!

[h100vw]

Good point about dv. No intercooler upgrade, only mods are intake pipe and apr.

Incidentally, are misfires always violent or can would they just feel like a slight loss of power? (Flat)

A misfire could be subtle.

Also, do you have multiple programs, 98 and 95 octane?

Certainly the intercooler could become soaked pretty quick and if intake temps jumped way up the ECU would pull timing like crazy.

VCDS when it's good and bad is the best way to see what's what.

Is your diverter valve all good? Not running the factory one still are you? The N75 died quite recently on my silver polo, though it's a huge difference in power, from having some to none, initially it was intermittent.

Gav/Guy, would it also be worth to log the requested and actual boost values??

Any good data will help you.

As Gav says., heatsoak is the #1 enemy and you can go screaming past 90C intake temps really quickly with the poor little Polo's side mount. It would have to have the worse intercooler fitted to a turbo VW in the last 15 years!

Hello i was wondering if the APR K04 map could be ran on a stage 2 polo full exhaust intake fmic

[h100vw]

I doubt it, the airflow from a K04 is substantially different to a K03s.

Hello is it possible to replace my apr stage 1 ecu with a stock ecu so i can sell it and get a custom code stage 2 tune will the apr stage 1 ecu work in other polos thxz

I can flash over the APR, you can get a spare ECU but the immobilisers need fixing. I can do that but at least one car will need to be off the road while I do it.

Your ECU will work in another car if you sort the immobiliser.

This is going back a few posts, but what happens if the coolant temp sensor plays up? (Assuming the thermostat is ok)

Incorrect information into the ECU will prevent it from running the engine correctly.

ie low temp input might prevent it from ever leaving the cold start cycle, there by using more fuel. Engine temp can be seen in measuring blocks with VCDS.

This is a bit interesting; some days my PoG takes 10-15mins for the temp gauge to reach full running temp (90deg), whilst others it takes literally 4 mins. I mentioned it to my mechanic and he seemed to think it was all fine, but doesn't quite seem right to me. Any thoughts?

Could be a intermittently sticky thermostat or just different driving conditions. Mine is pretty quick normally. Especially if on a clear road at 80kmh. Rolling to school with the kids is different.

[Blue9N3]

I would have thought that 10 mins or so is ok. The merc takes that long and it's only a year old

Just noticed that the car is running slightly less boost than normal, 1 bar instead of 1.2. Car feels the same. Does the ecu set the desired boost level based on a variety of factors or is it always fixed? Or do I have a dodgy boost gauge (More likely)

I would start with looking for a leak.
Boost wont vary much depending on conditions (depending on the tune).

Does lemmiwinks work on apr tunes?

You can see if it will connect and read the ECU.

I can't recall if I have tried it or unisettings before. You need to be logging it carefully.
