Oil Pressure Safety Trip with EcuTek RaceROM Custom Maps

[EcuTek]

Abbey Motorsport Developed...

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 motors, 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

Interesting thing is the way the oil pressure drops slightly at high RPM. We are 100% happy with datalog from the stock ECU. But something to work on with development

So you have fitted a aftermarket oil pressure sender ? and linked it into an ecu input

Yes and plumbed into the rear O2.
