RS200 – 8-injector 1.8L Cosworth BDT
Update February 2018:
The RS200 that we had at our workshop last year to do the initial set up on the new MBE9A8 ECU finally went on the dyno at DTW Engines, so mapped the 8-injector 1.8L Cosworth BDT, that is now 1952cc engine in a relatively mild state of tune since it is only used as an everyday road car, so we kept the boost levels down to 2Bar. All the settings of the engine were kept conservative since it needs durability and the engine still produce 503bhp and 405lbft torque. Also the dip you can see in the torque curve was from figure recorded earlier in the evening at lower boost, but by 10 o’clock at night when we had finished, we had forgotten to go back and re-test at 5500-6000rpm. We have also been informed that the exhaust system used on the car and the dyno is hugely restrictive, in order to keep the noise down to acceptable limits on the road! Once the owner Steve gets the engine back into the car, there will be some fine tuning for road manners.

September 2017 Our customer wanted to update from his MBE970, which had been on the RS200 for probably more than 20 years, to a modern MBE ECU with idle control because he uses the car every day. Steve suggested the MBE9A8 because this ECU is capable of doing idle control and also able to run 8-injectors, which the RS200 uses when under full boost. Steve spent several hours a few months ago converting the map over and a new wiring harness had been built. The car was delivered to SBD where Steve B made some fine adjustments to the engine settings and set up the idle control. The car was given some initial tests driving slowly around the estate ready for a further mapping session.
