Flat spot
« on: February 20, 2011, 10:24:39 pm »
Since i fitted my itg last week ive noticed a flat spot at around 5k. what could be the cause of this? will the map need adjusting? i thought the maf would adjust accordingly? or could it be something like the dv as it is running 260bhp and 312ftlb :evilgrin:

Could be a whole number of reasons.

Ideally you need to log the car to find what it's doing at that rpm

I had a flat spot which got progressively worse across the rev range, this was months after the remap so it wasn't that.........

After some logging it was diagnosed as a knackered DV - you can see from the picture it doesn't look healthly - its a different car now, and they are only 50ish quid from the stealer for the piston type revision 'D'.  :happy2:

could be a number of things, i had a flat spot at 5k for about 12 months on my old gti, changed all the sensors and did logs and still couldnt find it, so i put an edition 30 engine in it and found out once the engine was removed that the turbo had cracked.  :driver: :rolleye:

If it is a "custom map" from PDT would the settings not need to be changed if you have more air going through it with the maxogen

I had a flat spot @ 5900rpm, I told my tuner and he made a new stronger map for me with zero problems :star:
The Trueseal makes no difference to the smoothness of the drive, it just gives a little more torque/power on mine.

Holy s**t! Are them figures accurate? That's more torque than some stage 2+ cars are producing, and bhp is stage 2 territory............... :surprised:

Had they been on independant rollers id believe them :P

Reference the maxogen intake. The ECU will adjust in about 50 miles or so Mine had horrific flat spots on it after fitting the intake.  Mainly as the car will now be getting a huge influx of air compared to before so the air fuel ratio will be out for a while until it adjusts.  After about 50 miles of mixed (normal/aggressive) driving the ECU adapted and it was fine. You shouldnt need any map tweaks

BTW with your 258Hp and the extra 10-15Hp from the maxogen (usual gains for an intake) it looks like you may have the most powerful stage 1 K03 TFSI ever, by about 30-40hp :wink:  :P

i know the figures are high i was doubtfull at first but my mate has a megane sport 225 stage 2 @ 274bhp and 335ftlb and theres absolutely nothing in them neck and neck. search for a topic by pdt calles 'how much power from stage 1 k03 more than you may think'. this thread has graphs of the first car which actually got a couple more bhp than me i think. my car was the second to be done with this map
