Good morning
I'm currently arguing with my audi TT 8N 180 of the 1999 ? was Swappata from the engine stand sedan engine APX
and now I have huge problems with the ecu .. the one of the 180 does not have the scaling of the mass air flow sensor to 80mm (from the original 70mm)
while the ecu 225 mi silhouetted piccata and I pry off the gas because the excess pressure tot
the MAP sensor on both the ecu reads me max 1400mbar from 2380 command .. while on the gauge I have 1.6 peak and 1.2-1.1 constant
I tried to change 3 map sensors, including 2 of 225 (a new one) and the one that I had on the 180 . but all of the similar results that vary from 10 to 30mbar
the ecu 180 from vag sees me values lower on the maf of 30% and (70mm vs 80mm ) and tends to gain weight by itself without a reason after 100km I lambda values, respectively, 7% and 16.8%
while if I install the ecu of the 225 ? already mapped, I have problems in recovery when pike I get to 1.6 bar if not 1.7, and I cut the gas strattonando, as back in the 1.4 because of the rise of the rpm goes well, if the vo gas fires (likely to stop the hang-up and shoot for gasoline in the room..
from the vag on the engine I have the following errors :
the engine does not fit the secondary pump why don't I have the wiring and I have these errors :
17841 - Secondary Air Pump Relay (J299): Open Circuit
17840 - Secondary Air Injection Solenoid Valve (N112): Open Circuit
but I should cause huge problems .. in theory .. I have seen many rise up and apply resistance .. but I'm not having the wiring 225 I don't have the plugs .. I should find which pin are the related devices , if someone has a diagram.
what do you think from a first analysis?
