The Pendle calibration · 1 of 3
HR Auto Specialists reads your ECU and the file comes to Pendle HQ, where it is custom calibrated in WinOLS – torque, fuel, boost and timing together as one. It goes back to be written to your vehicle.
Correct OEM calibration: smooth power, inside the engine’s safety limits.
The Pendle calibration · 2 of 3
Every vehicle is data logged before and after the tune, and every log gets an in-depth data log report: boost requested against delivered, fuelling and rail pressure, across the whole rev range.
Turbo in control: boost within 0.05 bar of the request from 2,000 rpm. Real standard log, VW T5 2.0 TDI 102PS.
The Pendle calibration · 3 of 3
The dyno proves the power; the road proves the calibration. Our Road Drive Report shows the linear delivery, the smooth uptake of performance and the drivability – everyday driving, where a calibration is felt most.

Do it right the 1st time.
If your going to do it then do it right the 1st time and get a custom map wrote for your vehicle and your vehicle only - as long as Martin is trading then I wouldn’t look elsewhere!!!

More than just a generic flash.
