Only meant for use on OBD1 ECU's with the Hondata S300 system.
The stock distributor style ignitions system found on older Honda Prelude are often times worn out and can't provided a consistent spark. That is why the Hondata Coil Pack Retrofit Kit is a great upgrade. It will help your car run better and give you a much stronger spark which helps out especially on forced induction engines and high revving naturally aspirated engines.
The Hondata Coil Pack Retrofit Kit does this by replacing the stock coil and ignition with an electronic control unit which can drive igniter type ignition coils, basically giving each spark plug its own individual coil. Designed to be used on the Hondata S300 system, the CPR kit allows you to fine tune the performance of your engine and get the most power out of it. Additionally, the Hondata CPR can drive a CDI controller if needed, able to provided and even stronger spark for higher boost pressures and letting you run a larger spark plug gap.
This kit comes with the wiring harness for 4 Honda coil packs, the coil pack controller itself, and a flying leads harness to connect the kit to your distributor signal and the ECU. The Hondata Coil Pack Retrofit Controller can also be positioned basically anywhere and can be neatly mounted next to the ECU for a simple install.
Key Features:
- Improves driveability and reduces misfires.
- Allows for a larger spark plug gap for a bigger spark for high horsepower builds.
- Reduces the amount of stress put on the coil, by having one ignition coil per plug.
- Individual coils are less likely to fail than the stock coil and igniter.
- Capable of driving a CDI controller.
Important Notes: This is only meant for use on U.S. OBD1 ECU's with the Hondata S300 systems and 4 individual ignition coils. This Hondata CPR does not come with the required ignition coils. Hondata recommends the Honda Ignition Coil part number 30520-PVF-A01. Also, we recommend using some form of retention on engines without factory spark plug covers, to prevent the ignition coils from wiggling out. A good method would be to use Honda coil seals, part number 30522-RNA-A01.
The Hondata CPR Kit also requires an ECU with a Q37 transistor already installed. Some of the following ECU's are missing this transistor Q37, which is required for the CPR: PR4-L11, PR4-L61, PR4-A61, P06-C01, P06-C50. If your ECU does not have this transistor, you must either purchase an ECU that already has this or install one yourself. Reference the image bellow to verify whether or not your ECU has the Q37 transistor.
