Hondas switch the injectors on and off rapidly (red line). All Honda ECUs drive high impedance injectors or low impedance injectors with an external resistor box. These transistors do not even get warm (except when low impedance resistors are incorrectly wired in without the Honda resistor box!). These are excellent quality transistors, which make a substantial contribution to how the well the Honda ECU drives injectors.
Analog Output: Injector driver transistors This is where the 12V signals are conditioned and converted into 5V for processing - such as the distributor signals TPS and MAP. No other vehicle maker we are aware of uses a backup processor and this level of redundancy. This is military specification redundancy designed to keep you going even in the event of multiple sensor failures. Limp home mode is rev limited to 3500 RPM with a fixed ignition and rather rich fuel setting with the engine check light permanently on. In fact you can remove entirely the ROM and primary microprocessor and your Honda will still run. TDC (top dead centre from the distributor) and TPS (throttle position). In this mode the ECU needs only two sensors to run. In the event of a serious failure it takes over the running of the computer in what is called limp home mode. The backup microprocessor monitors the function of the main microprocessor, ROM and sensors. This tech article looks at the functions of the ECU and how it differs from some of the piggyback and standalone systems available. **We ship within 24 to 48hrs** IF INSURANCE IS NEEDED IT WILL BE AN ADDITONAL $1.The Honda ECU, like your Honda engine, is a very well designed piece of equipment made to work in many cars under many varying conditions of temperature and altitude. OUR CHIPS ARE SHIPPED ONLY WITHIN THE USA AND THROUGH USPS FIRST CLASS MAIL WITH TRACKING NUMBER. (PLEASE DO YOUR RESEARCH FIRST PRIOR TO BIDDING ) We strive to please our customers 100 percent. We been part of the Honda/Acura game for over 15 years and have gained a lot of knowledge and have gained a lot of knowledge about repairing ecus. What's included : (7) Toshiba TA8903SN We have a PERFECT 100% POSITIVE FEEDBACK. This part is also located in some obd2a and obd2b ecus aswell. This part is THE BRAND NEW PART that is located at IC17 on the p05, p06, p28, pr4, p75, p72 and p30 obd1 ecus. Does your obd1 obd2 ecu not activate your main relay? This is one of the main part that controls your main relay from functioning. LOT OF 7 BRAND NEW Toshiba TA8903SN We at JD TUNING can help you with that.
