Hello together, have converted with the mentioned module to operation with E85. Have no cold start problems. Only problems in working warm condition: – At a speed between approx. 80 and 100 km/h he jerks (lambda approx. 0.760). – When operating with tuning switch (at accelerator pedal) sporty set slightly less jerk. – I switch off the modulator – actually everything runs normal – although E85 is driven. Does anyone have advice for me? MfG Martin B.
