93 Octane

DSC disabled, stock map sensor. 3 port mac plugged in. Stuttering is still there when flooring the accelerator pedal from 0 - 100. Just wanted to test. 2E81 - DME: Electrical coolant pump, speed deviation still there. Also got a 2E84 - BSD, message; Electric coolant pump: Missing. That 2E84 is new code, but the 2E81 has been there since I swapped in a brand new waterpump. Will try and change the waterpump again, now with a brand new OEM one from BMW. Last time I used this one: https://www.ecstuning.com/b-bavarian-autosport-parts/water-pump/11517632426~bav/ .
