BMW Z1 CHIP TUNING
 |
This is a chip emulator. It replaces the
original chip whilst the best settings are found and stored for download
onto a new chip. a chip looks like this  |
I took the car to AmD near Oxford to have them re-programme the ECU. This is the car running on a rolling road dynometer with a chip emulator in between the engine management system and a portable computer. When the best figures were obtained the settings were saved and then re-programmed into a new eprom for the system. THIS WORKS. See plots below.

Maximum Power Speed 5897 rpm Power at flywheel 182.BHP Was 175 BHP Power at wheels 135 BHP It's the RED plot that is the one after the AmD re-programming |

Maximum torque speed 4206 rpm Maximum engine torque 182 Ft/Lbs Was 172 Tuned by  |
In terms of drivability the car feels much livelier due to the increased width of the top of both of these curves. What isn't shown on the charts is how the part throttle performance in improved, it is as if the engine is a couple of hundred cc bigger!
Don't get an off the shelf chip if you can get to a dyno shop. If they happen to be a Bosch Service Centre as well, and have wealth of experience in making BMWs go, stop, and corner better; then so much the better!
