An exceptionally tidy 635D we had in for an Evolution Chips Stage 1 Remap at PVE Somerset. These make obscene torque and power figures as they are, but always a bit of room for improvement. After a quick free full diagnostics scan, using out Bosch KTS, at PVE Somerset. After consultation with the customer we decided a Stage 1 tune was the most sensible option. This is the second car we have remapped for this customer. The last one was over three years ago on a 5 Series. The stage 1 tune is a remarkable increase of 45bhp, and an increase of 85NM. The Bosch ECU EDC16+ C35 we can read and write in the vehicle through the OBD port, or on the bench using our BDM programming tool. We can also adjust various other bits, including DPF removal, EGR delete, VSS and DTC delete, should we require to do so. We completed these works at our workshop, PVE, in Chard, Somerset.
Our stage 2 tune is an increase of 90BHP, and an increase of 170NM. Although this is beyond the recommended torque limit for the gearbox!
