Olá bom dia, tenho um del sol si 93, com um modulo 37820-p28-a51, o qual nao envia pulsos negativos aos injetores. qual o modelo de modulo compativel para ser substituido no meu carro?
Se alguém souber mostrar quais os modelos que existem e para quais veículos servem , e quais as diferenças entre um e outro. o que acrescenta ou tem a menos que outro.
o que muda em um modulo de cambio automatico para um manual? pode ser usado um modulo de cambio manual no veiculo de cambio automatico?

Hello good morning, I have a DELSOL SI 1.6 l. 16V, of 93, with a module of 37820-p28-a51, which is not sent to the injectors. What is the compatible module model to be replaced in my car? - -A52?
What's new shows which models exist and which most appear to be the same, and which are the differences between one and the other. which adds or has less than another.
What changes in an automatic changeover module for a manual? Can a manual shift module not be used for automatic shift?

thanks

Manual ECU lacks some of the parts required to operate the automatic transmission. There is basically no substitute for the auto P28 unless you are willing to modify the ECU and add parts.

Before blaming the ECU make absolutely sure the main relay is good.

The most common failure inside the ECU is a bad electrolytic capacitor. There are only 3 or 4 of them and someone with electronics experience could rather simply replace them.

Você precisa descobrir se o ecu ou o relé principal não está recebendo energia

Olá Tony , já verificaram e não recebe energia , pulso negativo do ECU. no numero 6. so falta isto para acionar a bomba de gasolina, testei com com um ecu manual 37820-p28-a... e funcionou normalmente o motor.

na ecu tem sinal positivo, ou seja tem energia.

será que a .... a52 serve em meu carro também? qual a diferença entre a A51, que é para meu carro, e a A52 ? no desmanche, me disseram que so é para acionar o teto solar que meu não tem. só isto? se for é so eu apagar a luz checkin engine com o scanner.

So capacitores MK?? já foi trocado dois deles.que estavam queimados. se trocar os demais resolve?

Hi Tony, already verified and no energy delivered, negative pulse of the ECU.at number 6. only is a gasoline pump, test with a manual 37820-p28-a ... and the engine normally ran.

in the ECU has positive signal, that is, has energy.

will a .... a52 serve in my car too?what's the difference between the A51, which is for my car, and the A52?do not dismantle, told me that's just to power the solar roof that mine do not have.just this?It's for me to turn off the light check engine with the scanner.

So MK capacitors ??Two of them were already changed. They were burned.if you change the others, will you?

obrigado thank you

Some more information, about ECU : and what changes in the version, final number, diferente?

alguma outra informação sobre a ECU : e o que muda de uma versão para outra? numero final , de diferente? pex. de 51 para 52 ?

Technical Information ECU Identification

Identifying your ECU

To identify your ECU you will need to know its generation, part number and possibly its ROM number.

The ECU can be located in several places: under a metal plate in the passenger's footwell (models up to 91), in the passenger's footwell behind a plastic panel (models 92-99) or by the driver's footwell under a plastic panel (some models 2000+)

The computer is connected via three connectors that pull out when a plastic clip is pressed. Remove the computer, and with a philips screwdriver remove the metal lid from the top of the computer. There may be small daughter circuit board covering some of the main circuitry. Unscrew this and lift it out of the way.

ECU Generations

Honda ECUs run in generations, which use different connectors. Below is a stack of ECUs running from the newest generation at the top to the oldest generation at the bottom.
OBD2B (left 3 plugs used)
OBD2A ECU
OBD1 ECU
OBD0 (JDM PR3 and PWO)

ECU Part Numbers

All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. e.g. 37820-P72-A01

The part number consists of three components:

• Honda's part number for ECU, which is always 37820
• Three characters (which are loosely related to the model of car/engine). e.g P72
• Three characters (which are the revision of the ECU) e.g. A01 or G52

The middle three characters are the most useful to identify what the ECU is. Different generation ECUs may use the same characters. e.g. a P72 OBD I ECU is different from a P72 OBD II ECU. Here is a list of common ECUs:

The last 3 characters are broken down into 3 parts. "A" generally is used for US ECUs. "G" is European, and "J" is Japanese. There are other versions of this, but you get the idea. The second digit "0" typically means manual transmission, where a "5" means automatic transmission, and the last digit "1" is the version number.

ECU ROM Numbers

As further identification Honda ECUs have a software revision number inside the ECU. This is usually a two or three digit number stamped on the 28 pin ROM, or main processor. Accord and Prelude ECUs can use a letter and number code.

1. quem lhe disse que um ecu é específico para um modelo por causa do teto solar é uma mec nica de inexperiência completa.

2. se o carro correu com um ecu manual do que o seu óbvio, há algo errado com o seu ecu atual.

Paz para fora, wacanda para a vida

A52 should be merely a later version of the A51 and be usable in your car. The ECU does not have anything to do with the sunroof.

If capacitors have leaked, you have to clean up the leaked fluid and repair any corrosion damage it did to the board or other parts.
