You are responsible for paying for and sending your ECU to Hondata. You can send your ECU as fast as you would like and shipping costs normally start at $10.00 for ground and $60.00+ for next day air. We recommend using an express service (2 day or next day) through FedEx or UPS because they have the least amount of delivery problems, provide proper insurance, and have good package tracking. We recommend that you do not use USPS because of delivery issues. You are not sending your ECU to K Series Parts you will be sending it to Hondata directly and we provide all of the instructions on where it needs to be sent once your order is approved.
After we approve your order we will send you two emails, one email will be a Hondata form and the other email will be instructions for shipping and what items need to be included. Orders submitted by 3:00pm Mountain Standard Time Monday to Friday are normally approved same day. Orders places after 3:00pm MST or on Saturday and Sunday are processed the next business day.
Hondata normally reflashes ECU's the same day they receive them but they do get busy and it might take an extra business day. We recommend that you plan on a 3 day total turnaround time from the day that Hondata receives your ECU.
Hondata uses K Series Parts FedEx account to next day air the ECU back to you once the reflash has been installed. This means that you do not have to pay for return shipping. Your ECU will arrive by 3:00pm the day after Hondata completes the reflash installation. Hondata does not provide us with a tracking number or notification when they ship the ECU back to you.
ECU Serial Number
The serial number is located on the ECU. Hondata has provided instructions on how to remove the ECU.
K Series Parts cannot sell reflashes to customers outside of the United States per Hondata request. The shipping address must be a US based address.
This reflash will work very well with an 06-08 S2000 in stock form, or with intake and exhaust. This reflash is now incorporated into the FlashPro for the S2000 - a recommended tunable alternative.
- VTEC point decreased from 6000 rpm to 5600 rpm
- VTEC window from 5600 to 6400 rpm.
- Rev limit 8500 rpm
- Maximum torque gain 14 ft/lbs torque at 5800 rpm
- Maximum power gain 16 hp at 5800 rpm
- Fully dealer compatible - works with all Honda scan tools and equipment
- California emissions legal (CARB EO D-742)
- ECU Part numbers: 37820-PZX-A09 to 37820-PZX-A21
The 06 S2000 is the first S2000 by Honda to have a programmable ECU. Our observations are that this is a very well tuned car from the factory. There were no peak power gains, but by raising the rev limit will increase the average power available when you shift at the rev limit.
The VTEC transition is much smoother than before. Peak torque may look as if has been reduced slightly, but this is an artifact of the dyno trying to catch the engine accelerating after the VTEC switch point.
The intakes manifold on the S2000 series engines get very hot. They have a metal intake gasket which transfers heat from the head very quickly. Pay lots of attention to keeping everything cool and you will see results. The S2000 Hondata intake gasket reduces intake temps about 15-40 degrees F, adds 2-4 ft pounds of torque and 4-5 peak HP.
- The VTEC window operates between 5600 and 6400 rpm.
- At sea level the VTEC point is 5600 RPM.
- Under 5600 RPM the engine is always on the low cam
- Over 6400 RPM the engine is always on the high cam
- As you increase in altitude and the air pressure drops, the VTEC point will rise from 5600 to 6400 rpm. If you live permanently at a high altitude, then this reflash may not be effective for you.
Unlike reflashes for other Honda models you will not need to send the key and immobilizer; just the ECU.
Any increase in RPM limit is at your own risk. If you suffer engine damage that is related to excessive revs Honda / Acura will not cover your warranty.
With regard to aftermarket parts, the law is that warranty coverage cannot be denied simply because such parts are present on the vehicle, or have been used. For more details read the K series FAQ.
Honda may not cover mechanical damage to the engine under warranty resulting from exceeding the factory red line. Hondata & K Series Parts will not cover any damage as a result of installing this product.
