As we have been trying to finalize the Standback2 development for the naturally aspirated Mazda3 vehicles – Mazda seems to be throwing at us new challenges in taking control of the engine.
The latest challenge consists of figuring out how to help the Standback™ lock on to the Mazda crank pattern that’s found on some 07-09 vehicles. In our research we have found that not only the crank patterns are different but the sensor used to read those patterns varies quite a bit as well – while that can be an obvious assumption – at the same time we have no data on those sensors that would indicate margins of error and manufacturing specs.
The effectiveness of the Standback™ in large depends on the accuracy of sensors, or rather our understanding of those sensors and understanding the discrepancies between the sensors. In this case – the crank position sensor – seems to have a wide margin of error – which we have to account for when programming the Standback™ to read that sensor.
The 07+ Mazda3 vehicles that we have worked with before seemed to have very solid, consistent sensors – and we had programmed the Standback™ based on those sensors. While this allowed us to track and lock onto the crank pattern and effectively tune the vehicles – we were very surprised to hear that on some vehicles, manufactured around the same time, the Standback™ would not track the crank. For some time we did not have access to cars that had the same symptoms – until this past weekend
Over the past weekend we got a chance to take a look at a 2008.5 Mazda3 – and after installing the Standback™ we realized that we finally found a car which tripped up the Standback™ – this meant the car was not going to run the Standback™ – we were at the same time relieved to get a chance to analyze the situation.
After a full day with the car with various diagnostic tools for collecting data – we traced the crank issues to the sensor inconsistency. Since we do not have access to any data information about the sensors or their margins of error and such – we needed to find out for ourselves.
At this point we have worked out new algorithms for the Standback™ to accept various discrepancies with the crank sensors – later this week we will test the new code on a vehicle and after that finalize the software to accept and read out proper RPMs from the vehicle.
Our progress is great and the Standback™ on the 07+ cars is looking up – we hope to finalize the Standback™ development for these vehicles so that our customers can enjoy a solid tuning solution for their cars.
