Provided your engine is maintained correctly this modification should not affect the engine's life. Will this affect the fuel economy?Īssuming you drive the vehicle in the same way, no. Shipping in the continental USA is FEDEX next day. The ECU will be reprogrammed and shipped out the same day it is received. Flashing the ECU does not in any way alter the immobilizer operation. All other reflashes do not need to send a key or immobilizer. Your dealer or you will need to remove and send your ECU, immobilizer and key to Hondata.All sales are made through Hondata dealers. The ECU can be repeatedly reprogrammed without removing or replacing and internal components. Some 2002 onwards and all 2006 onwards ECUs are flash programmable. This is what it looks like - in place and removed from the car. The ECU is located behind plastic panels to the left of the driver's left foot. Fill out this form and contact a Hondata dealer. Unlike reflashes for other Honda models you will not need to send the key and immobilizer just the ECU. You will need to remove the ECU and via a dealer send it to Hondata. 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. If the header does not work then your options are to switch to a Toda header or return your ECU to stock.Ĭan I use an 2006 ECU in my 2000-2005 vehicle? You should always dyno the engine with the reflash to make sure the air/fuel is within a safe range. While we will not create custom tunes for any other combinations of bolt on parts, other headers will probably be ok. If you already have the reflash for the stock 06 S2000 then the upgrade price is $200. What if I already have the reflash for the stock S2000? 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. Pay lots of attention to keeping everything cool and you will see results. They have a metal intake gasket which transfers heat from the head very quickly. The intakes manifold on the S2000 series engines get very hot. Lowering the VTEC point adding fuel and optimizing the ignition resulted in the reflash detailed above.Ĭombining an ECU reflash with a Toda header makes more gains than each individual item. The gains were only minimal, partially because the car was running very lean from 5500-6000 rpm. The Toda header and test pipe were first tested with the standard Hondata 06 S2000 reflash. The purpose of this test was to see the difference the Toda header and test pipe made. 06 S2000 with Heatshield gasket, exhaust and Hondata reflash with Toda header and test pipe - blue line.06 S2000 with Heatshield gasket, exhaust and Hondata reflash with stock header and cat - red line.Between 4200 rpm and 6000 rpm you are on the low cam at cruise and light throttle switching instantly to the high cam at wide open throttle. Over 6000 rpm you will always be on the high cam. Under 4200 rpm you will always be on the low cam. Midrange torque from 4500 rpm to 6000 rpm is substantially improved peak power only marginally.ĭifferent types dynos will display different peak power numbers, however the gains shown between 42 rpm will be similar regardless of the dyno you use.įor this reflash we implement a VTEC window. The dyno chart represents the gains you can get with a Toda header, test pipe and reflash. The heatshield gasket adds this torque to a stock S2000. There was no specific tuning for the gasket. The Hondata gasket adds about 3-4 ft pounds of torque across the rev range. The only change between the two runs was the ECU program.įor clarification. This dyno chart shows an 06 S2000 with Toda header, test pipe, Hondata heatshield intake gasket and exhaust. Dotted red line - Reflashed ECU with Toda Header program.Results for 06 S2000 with Toda Header, test pipe, exhaust and Hondata Heatshield gasket
