Fuel tuning (part 2)
This is a network with motor speed on one side and motor stack on the alternate. The MAP or MAF sensor sign tells us motor stack and, taking into account this and the motor speed, the ECU finds the a few organizes on the fuel guide and infuses the right sum of fuel. Programmable ECUs permit you to update these qualities and update the AFRs throughout the managing run on the motor.
This one’s a biggie. This sensor is the mechanism that tells us the AFR. Without it, you could not venture to usefully tune. Mounted in the fumes stream, it measures the measure of oxygen leaving the burning chambers and is utilized by the machine to figure the AFR. There are a few sorts of O2 sensors: tight and wideband. Unless you exist in the third-globe or you like off base information and crappy tunes, get the wideband. It’s quicker and has a useable AFR go (10:1 to 20:10), while the narrowband works well just around stoich (14:1 to 15:1). Since $200 is still too much for the cheapest of ya’ll, there’s consistently the DIY wideband O2.
