HPtuners E90 UNLOCKED ECM issues !!

[xperformance]

Hi

anyone ran into a similar issues with 2019+ unlocked hptuners PCM , attached a 2019 DENALI FILE , MAF table looks very odd HZ MAXED out at 6000 hertz airflow low at higher HZ and high at low HZ, car runs very rich , keeps showing P0118 engine coolant code , sensor reads correctly no actual issues.

emailed support and they said everything looks correct !!

let me know if i am the only one who sees the MAF table looks wrong. Untitled.jpg

Welcome to the e90

its all reversed, you will idle at highest MAF Freq and will decrease with load

doesn't seem right , MAF still reads normally at idle and increases with higher engine speeds.

check out this 2020 log, after auto generated file i was looking at the maf curve and was thinking the same as you did.

did a log un-tuned to confirm

still not enough resolution , 750hz has lower airflow than 1000hz, if it is reversed , should be linear , on a supercharged car this will be a mess lol

You can edit the axis

You can edit the axis

doesn't change anything maf only reads between 2800HZ and 1600HZ, this car is supercharged , something isn't correct.

keep showing error codes
U0284 - Lost Communication with Active Grille Air Shutter Module A
U060F - Lost Communication With Mass or Volume Air Flow Sensor A
P0118 - Engine Coolant Temperature Sensor 1 Circuit High
P2796 - Auxiliary Transmission Fluid Pump Relay Control Circuit

coolant temp works fine , MAF is working.

it goes to open loop cant do anything to clear the codes
