In the depths of Abbey Motorsport Ltd dyno room we have been working away on developing the GT86?BRZ one of the developments is an Oil pressure trip for these FA20 motor s, nothing new but just needed to developed for these cars. It also allowed us to look into the oil pressure on these motors , anyone with an oil pressure gauge will see there is big fluctuation in cold to hot oil temp. We have found a few items on the motor that can be worked on to fix these issues also we have noticed that engine revs has an influence with oil pressure. here is a datalog from a built FA20 with Abbey tweaks on the oiling system when run on our dyno this week. With the inputted oil pressure into the RaceRom feature of the EcuTek International Ltd software we can add a fuel cut to limit the motor if the oil pressure drops below a calibrated number with a RaceRom map , this allows us to basically limit the car if the oil pressure is below the level we are happy with.we added a delay on the fuel cut happening to allow for transition area's. Something to help look after these FA20 motors when used on the circuits

I always wonder why people say the above; I feel if someone knows how to use a dyno a dyno is a far better piece of equipment to tune car on; Can you tell if you have the cams in a right place or if the maximum advance you can run on the road will give maximum performance by tuning on the road. I think when we have the next dyno day we will spend sometime on the dyno and show everyone why you need a dyno to tune these cars.
