I recently bought a 1997 integra gsr that needs a new ecu. I was told i should buy a socketed hondata s300v3 p72 with a jumper. I’m honestly not too knowledgeable on ecu’s but i wanted the best possible ecu i could get disregarding the price as the one I mentioned goes for $900 on ebay. Would this ecu be the best for my car if i plan on doing lots of modifications to my engine?

 

get another stock ecu


what is the reasoning for a replacement ecu?

what type of modification are you looking to do?

 

honestly i plan on doing a whole rebuilt engine and turbo soon after. I have the money to get the hondata one just want to be 100% sure yfm?

 

you will probably have around 800.00 into hondata.

get yourself a standalone

aem, haltech, fuel tech

 

I have a new never been used P28 Ecu with Hondata S300 on it. All work done by Phearable which is a well reputable company. Message me if you are interested, it’s been sitting in my laundry room collecting dust on the box.

 

I would buy this if its the V3 because i was about to recommend sending a message to Pheriable to purchase one from them.

If you plan to mod the engine especially a turbo you will need the S300 V3. the V2 will work but its a bit older.

With the S300 you can upload a stock GSR base map from the vault, they have tons of free maps to choose to get your engine running. You might find a GSR map with basic bolt ons and use that to drive around instead of buying a stock gsr ecu and have no tuning functions available. Then when your ready you can have the engine tuned.

 

Mine is also the V3. Still have the original receipt to prove everything too.

Options on receipt read:

• Hondata S300 V3 Package
• S300 system Pre-Installed into OBD1 Vtec ECU
• New ECU capacitors
• Boost Control Package: PWM Boost Control Hardware only
• Conversion Harness added OBD2 to OBD1
• Add Phearable.net ECU Cover: Yes
