• Hondata Reflash - S2000 2006-2008 F22C stock

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)

This is for an ECU reflash - the ECU is not included.  Hondata does not sell direct - the reflash must be purchased from a Hondata dealer. The ECU reflash form must be sent with your ECU.

Tuning Notes.

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.

VTEC Window

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.

How do I get the reflash?

You will need to remove the ECU and via a dealer send it to Hondata. Unlike reflashes for other Honda models you will not need to send the key and immobilizer; just the ECU. Fill out this form and contact a Hondata dealer. Hondata does not sell direct.

What If I want to add parts later?

We have developed a reflash to work with the TODA header. The upgrade price is $200.

Can I use an 2006 ECU in my 2000-2005 vehicle?

This is not easy nor cheap, and we do not offer support for such a swap - at the least the engine sensors, sensor wheels, throttle body, ECU, vehicle harness, ECU harness, dash harness and cluster would need to be changed.

How do I remove my ECU?

The ECU is located behind plastic panels to the left of the driver's left foot. You will need a 10mm socket. This is what it looks like - in place and removed from the car.

What is the difference between a reflash and the FlashPro?
The FlashPro is tunable by anyone.  Most of Hondata's reflashes are available on the FlashPro as one of the many default calibrations available.

How much power will the FlashPro make on my car?
The FlashPro itself does not make power. The combination of parts and your engine makes the power. The FlashPro allows you to tune the correct cam angle fuel and ignition your car needs. The base maps are a great place to start though. The Maps page lists the calibrations available with the FlashPro and the power made compared to a stock Civic Si. Take a look at these dyno charts from our dyno day on a number of modified Civics with stock ECUS compared to a base map from FlashPro.

Do I need dyno tuning?
It shouldn't be necessary for common part combinations (intake, exhaust), but you still have the option of custom tuning if you wish to get a little more. Camshafts and race headers probably will need tuning to get the most of the them - it will depend on the manufacturer.

Can I get rid of the AFM?
You can switch to a MAP based calibration (recommended for forced induction and/or cams). You need to still physically retain the AFM because it also contains the IAT sensor.

Will this work on more than one vehicle?
The FlashPro is locked to one vehicle. It can be unlocked and transferred to another vehicle by returning the ECU to stock.

Can I share the calibrations I make for my car?

Do I need the laptop in the vehicle to reflash the ECU?
No. The FlashPro can upload either with or without a laptop.

How do I buy a used FlashPro?
Follow these instructions

Is there a VTEC window?
Yes. This means that VTEC will operate based on rpm and engine load. For example, the supercharger reflashes have a VTEC window from 3200 rpm - 6000 rpm. At full throttle, VTEC operates at 3200 rpm. At light throttle, VTEC operates at 6000 rpm, and for load between full and light the VTEC will shift between 3200 rpm and 6000 rpm.

So does that mean 1 unit Hondata FlashPro can only work with one ecu or car only? Which means I can't buy one FlashPro and use it together with a few of my buddies Civics?
One ECU and vehicle at a time. You can unlock the FlashPro by returning the ECU to stock, and then transfer to another vehicle.

Any option of immobilizer control?
The immobilizer can not be disabled. We've implemented a number of features designed to protect the owner of the vehicle from theft, and one of these is not to allow the immobilizer to be disabled. This is going to be much less of an issue than previous products because the ECU does not need to be removed / swapped.

If the ECU had been reflashed by another maker, can FlashPro still work?
Probably - we could tell you based off the ECU part & serial numbers plus the calibration ID. When you unlock the FlashPro it will only be reflashed back to a stock calibration.

Can it control nitrous?
No. However, you can at least control the ignition timing to make nitrous safer.

Will dealers need a software license?
No. Every FlashPro will come with the full tuning software FlashProManager.

Do I need to send my ECU to Hondata?
No. Your ECU does not need to be modified for FlashPro.

I am considering purchasing a used FlashPro. What do I need to do to check?
The FlashPro must be unlocked by the seller. Have the seller send you this screenshot which shows the serial number password and lock status. Hondata does not unlock FlashPros. The reason for this policy is to prevent both fraud (against us) and theft (against you)

How does the FlashPro work with my  FN2 GroupN ECU /  FD2 Civic Type R ECU

The FlashPro will lock to and work with the FN2 GroupN  / FD2 Type R ECUs perfectly. However if you unlock the FlashPro for sale and return to stock the GroupN ECU will be returned to a stock US Civic Si ECU. In this state it will not work in the Euro and Japanese Type R Civics.

How does it compare to KPro?

KPro is a completely different product. It was created for the 02-04 RSX style ECU. It will only work on that type of ECU with the exact same Oki processor. Honda has changed the architecture of the ECU, including ECU architecture, processor and encapsulation, so that there is no way the KPro can be made to work on any other ECU.

K-Pro requires the ECU be sent to a Hondata for the installation of the K-Pro daughterboard. By comparison, new FlashPro owners need never remove the ECU from their car.

Because FlashPro is a different product from KPro, it has different features.  Not all features implemented in KPro are possible with FlashPro.  We will try to develop more popular features as time permits.

In the meantime, if you run nitrous, you will be able to run a calibration that is far safer and make more power than you would with a stock ECU.

Can I used a FlashPro for an engine swap into an earlier chassis?

Unless the chassis is substantially the same as the donor engine (eg 2007 engine in 2006 chassis of the same type) we do not recommend that a FlashPro is used for an engine swap.  The KPro should be used, with 2002-2004 engine harness, ECU and transmission speed sensor.  The throttle body should be swapped to a non DBW type.

Can I upgrade my older FlashPro for a Bluetooth enabled model?

Yes. For $150 + shipping (around 20% the cost of a new FlashPro), Hondata will upgrade your old FlashPro and give it a 1 year warranty. Download the upgrade form.
