Hey guys, I’ve got a 2022 Toyota Supra that I got in august and I ordered the dme unlock package from a90 shop. It comes with a bm3 lisense and a catless downpipe.
After installing the downpipe and putting the unlocked dme in, I flashed the tune and fired up the car,this where things went wrong. I got a check engine light which threw a code (135808 Valvetronic servomotor, position sensors, electrical: Malfunction). The car was rough idling, very very smelly, and making a clunking ticking front near to the catless downpipe area. I put the car back to the stock tune and it seem like rough idle wasn’t so back and the ticking noise went mostly away. So I took the car around the block to help with recharging the battery and the car would stall when coming to stop and mpg was very low.
I’ve checked all the connections multiple time along all the areas I worked around very carefully and everything seems tight and secure. Has anyone ever experienced this or know what may be the problem?
