All Honda ECU’s have an ECU part number which is located on the side of the ECU which allows for easy identification
The part number is composed of three parts: * The ECU part number for Honda always begins with 37820- * Three characters (who are tangentially tied to the car/engine model). e.g P72 Three characters, please (which are the revision of the ECU) such as A01 or G52
The most helpful characters for determining the type of ECU are the middle three characters. The same characters may be used by ECUs from different generations. For instance, a P75 OBD I ECU and a P75 OBD II ECU differ.
The final three characters are divided into three segments. Typically, “A” is used for USDM ECUs. G stands for European, J for Japanese, etc. The last digit is the version number, the second digit is normally “0” for manual gearbox, “5” for automatic transmission, etc.
Describe the P28 ECU.
Electronically speaking, a P28 equivalent is an ECU that is identical to a P28 ECU. The majority of P28 ECUs use the standard Honda ’11F0′ ECU circuit board, which has the necessary components soldered on. While this circuit board may be used by other popular ECUs like the P05, P06, PR4, etc., some of the electrical components are not soldered into place like they are in the P28. Another 11F0 ecu board is modified to become our “p28 equivalent” by adding the required parts to make it the same as a p28. The only real distinction is that instead of the ECU manufacturer, we installed the electrical parts.
Is remapping superior to chipping?
Therefore, if your car was manufactured before 2000 and you want to improve its performance and economy, you will need a chip tune. You require ECU remapping if you operate a vehicle manufactured after 2000.
What makes a chip different from a tuner?
Flash Tuners/Programmers: These devices reprogram your engine’s computer with more aggressive mappings and typically come with a variety of mappings that can be downloaded or loaded onto the device.
Modules or chips that are installed in-line with the ECU intercept signals and change them to produce extra power. These leave no trace and can be put back to stock by simply deleting the chip.
Want to learn more about these and related issues in-depth? Read on below:
Tuners for performance:
These have perhaps the most flexibility and are unquestionably more popular on the market today. Modern programmers frequently come with dashboard- or windshield-mountable displays that serve as performance monitors and troubleshooting screens. These can frequently be set up to function as complete digital dashboards that can be customized with the gauges you desire, in-depth trip computers, data logging, and different acceleration and lap timers.
Numerous of these tuners also allow you to change the shift points on automatic transmissions, have multiple mappings for various performance and economy settings, and can even be updated through WiFi for new firmware and tunes. Really bizarre, huh?
They are frequently more expensive as a result of all these extra capabilities, but we also provide more basic programmers whose sole purpose is to provide you more power. You have a ton of options depending on the vehicle you drive.
How can you tell whether a Honda ECU is manual or automatic?
The second-to-last digit of the part number is a 5, and it is used for automatic ECUs. P28-A02 is manual, whereas P28-A52 is an automatic. Since it is manual,
The Hondata ECU is what?
Standard Honda engine computers (ECUs) are modified by Hondata, adding features and enhancing the ECU’s capabilities (e.g. for forced induction). These changes are offered as a reflash or a fully adjustable system.
My car will accept any ECU, right?
Do you intend to replace your engine and are curious as to whether the Electronic Control Unit (ECU) will also need to be replaced to match the engine? You’ve found the perfect site since we’ve done our research and have the solution for you.
The Electronic Control Unit (ECU) controls many of the functions of a contemporary automotive engine. Your car’s engine and ECU should be compatible for the two to function as a single unit. Airflow, fuel injection, and combustion cannot be regulated by your ECU if it cannot communicate with your engine.
In the parts that follow, you’ll learn more about how the ECU interacts with your car’s engine and why this interaction needs to be positive. Read on!

What type of ECU is in my car?
Vectra models, at the engine bay’s outermost row, under the plastic trim and cover updated Vectra models are situated in front of the Vehicle Selector on the driver’s side wheel arch. The ecu is situated in the passenger front wheel arch, next to the front bumper, on Zafira vehicles.
What ECU Make & Model Version Do I Have?
You’ll probably want to know what kind and model of ECU you have once you’ve found it and removed it. A sticker with the Make and several serial numbers will be present on the ECU. Each ECU has a unique structure for identifying the model of the ECU. You can also find your car’s make, model, and ECU brand and model by using the two PDF files below. Use our FREE VRM tool in the website footer if you are unsure of your car’s make and model. Simply type in your vehicle’s registration number.
How can you identify a P28 ECU?
You might not be able to just tune your vehicle because you have an OBD 0 or OBD I ECU. Look at the side of your ECU; it has the number 37820-PXX-XXX. The numbers that come after the P, such as P28 or P30, are crucial. Regarding the most typical variations, take note of the following:
- P75 is identical to P72 but without a knock board and a VTEC control.
- VTEC P30Del Sol
- P28-like but with a knock board
- P06JDM CivicIdentical to P06, but with VTEC
- Civic P05
- ECUs with the simplest support. Disable this to prevent a CEL if it doesn’t have an O2 Heater circuit.
- P72 is identical to P30 but has IAB control
- P06 Civic DX is identical to P05, but has a heater circuit.
- P28Civic Ex/SiThe typical tune ECU is the Civic.

What kind of vehicle is a b18b?
From 1990 to 1991, the 1.8L motor produced 130 hp, and from 1992 to 1993, it produced 140 hp, a tiny increase. The 1.8L engine’s 121 ft-lbs of torque, though, was what made it so stunning. The B18A1 was later upgraded to a B18B1 and used in the RS/LS/GS bodywork for the 1994–2001 Acura Integra.
SST chip: what is it?
For OBD1 ECUs, the SST 27SF512 chip is ideal. With these blank chips, you can repeatedly program the same chip with your music as necessary. Two 256k ROM programs can fit onto each chip of this huge a chip. need a chip programmer like the Moates BURN2 that can program 28 pin EEprom chips. Fits any 28 pin DIP or 28 pin ZIF socket that is industry standard. Please look at our bespoke basemap programs for a quick pre-programmed chip solution if you are a customer without a chip programmer.
Does a car’s engine suffer if it becomes chipped?
Some consumers worry that engine remapping can result in issues with their vehicle. However, if you work with a respectable business, it shouldn’t influence reliability.
An engine is put under a little bit more stress during remapping, but not a risky amount. When creating their products, remapping companies will carefully monitor the pressures and temperatures that remaps subject the engine to. The majority of car engines are designed to be more powerful than they actually are, so the additional power shouldn’t put too much strain on them.
Can remaps be recognized?
Can insurance determine whether a car has been remapped? is a common query from drivers. They might learn that the answer is no.
Even though some plans may imply the insurance can inspect a vehicle if they want to, insurers don’t inspect cars before providing coverage, thus in practice, your insurer won’t sporadically check your car for remapping.
A garage, however, will be able to check for remapping if there is a claim and your automobile is damaged by looking at the engine’s electrical control unit (ECU). The garage will probably notify the insurer in a damage inspection report if it has been altered.
Performance chips: Do they actually work?
Although they might boost your power, performance chips can raise the possibility of an engine power failure. Manufacturers’ claimed advances frequently don’t correspond to actual performance. Any existing warranty on your car would be nullified if you installed a performance chip.
