Anyone running 1,4 bar chip ever had dtc 17743
Which is Engine Torque Monitor 2 Control Limit Exceeded?
Could it be any possible correlation between this dtc and hot weather? I've been running MTM Stage 3 chip with RS4 gutted DPs for a couple of months to my great satisfaction and with no problems. However this week when the temperature here in Moscow hit 32 Celsius (around (90 F I guess) several times I got this dtc together with EPC light and limp mode. Both times that happened under modest acceleration (not WOT) and coming out of the traffic jam. So what could be the reason? STFAed but with little results. MAF seems OK, reads up to 360 g/s, and no visible leaks. My local tuner says this dtc is normal for 1,4 bar chip an I should just reconcile. Any ideas?
TIA

If your maf is reading a touch higher than it should, either failure or wrong part, and your ECU has
it's torque limit set very close to the torque it is making it can trip that DTC.
It could also be a slight intake leak on the pressurized side of the intake making your maf read high under boost and tripping the DTC.
