Setting Rev limits
Programming the revs
The rpm points are initially set to the following: Launch limiter 3000 rpm (stage 3 & 4) Cam change point 4800 rpm Shift limiter 6000 rpm (stage 3 & 4) Shift light 7800 rpm Rev limiter 8500 rpm Pressing and holding the button for several seconds while switching the ignition on will reset all the rpm points to the Hondata defaults. Do this the first time the system is installed into the car.
Methods of setting revs
There are two methods of setting the rev points: dynamic which is quick and static which is accurate. A video explanation of this is available from
http://www.hondata.com/media.html
The launch limiter, cam change point, shift limiter, shift light and overall rev limiter can all be adjusted using the rev set button. Pressing the button will put the computer into a 'setup mode'. If the engine is running, then the revs can be set by varying the engine speed and pressing the brake pedal (dynamic rpm setting). If the engine is not running, the rpm points can be set by pressing the button to set the thousands and hundreds of revs (static rpm setting).
Dynamic rpm setting
Dynamic rpm setting is quick but less accurate than static setting. With your foot off the brake start the engine. Press the rev set button once. The check engine light will start flashing a sequence of between 1 and 4 flashes, which indicates the rpm value that is to be changed. Pressing the button again will cycle through the rpm point that is to be changed 1,2,3,4, 1,2,3,4, 1,2,3,...
Check engine light Function Allowable rpm range
1 flash = launch limiter rpm 1500 - 8000 rpm
2 flashes = cam change rpm 2000 - 8000 rpm
3 flashes = shift limiter rpm 5000 - 8000 rpm
4 flashes = shift light rpm 2000 - 9000 rpm
The revs for the launch limiter and cam change point, are set by selecting the mode, bringing the engine revs up to the desired point and tapping the brake pedal. The engine revs at that point will be remembered. Because it is difficult to set the higher rpm points by revving the engine to over 7000 rpm, the shift limiter, shift light are set at twice the revs when the brake pedal is tapped.
1 flash = launch limiter rpm current rpm
2 flashes = cam change rpm current rpm
3 flashes = shift limiter rpm twice current rpm
4 flashes = shift light rpm twice current rpm
Examples
To set the launch limiter to 3500 rpm: Press the button once. The check engine light will flash once, with a one second pause between flashes. Increase the engine revs to 3500 rpm and tap the brake pedal. Switch the ignition off. The launch limiter is now set to 3500 rpm.
To set the shift light to 8000 rpm: Press the button four times. The check engine light will flash four times quickly, with a one second pause between groups of flashes. Increase the engine revs to 4000 rpm, and tap the brake pedal. Switch the engine off then restart. The shift light will now be set to 8000 rpm.
Note that if the rev set button is pressed with the brake on, the launch rpm will be set to the engine speed at the time the button was pressed (within the allowable default RPM limits).
Static rpm setting
Static rpm setting is more accurate than dynamic setting but more time consuming to perform. With your foot off the brake turn on the ignition but do not start the car. Press the rev set button once. The check engine light will start flashing the rpm option that is to be changed, as in dynamic setup. Press the button additionally to select the rpm point to change, then tap the brake pedal.
The check engine light will now start flashing the thousands of revs, from 1 to 9 flashes. 1 flash = 1000 rpm, 9 flashes = 9000 rpm. Pressing the button will increase the thousand rev flashes. Tap the brake pedal to select the thousands of
revs.
The check engine light will then start to flash the hundreds of revs, from 1 to 10 flashes. 1 flash = 0 rpm, 10 flashes = 900 rpm.
Switch the ignition off after setting both static and dynamic the static limits. After the car starts rev limits will not be active for 10 seconds until the Hondata interface board and ECU complete their diagnostics.
Examples
To set the launch limiter to 3500: Press the button once. The check engine light will flash once, with a one second pause between flashes. Tap the brake pedal. The check engine light will start to flash the thousands of revs. Press the button twice, so the check engine light flashes groups of three (3000 rpm). Tap the brake pedal. The check engine light will start to flash hundreds of revs. Press the button five times, so the check engine light flashes groups of six (500 rpm). Tap the brake pedal. Switch the engine off then restart. The launch limit is set to 3500 rpm.
To set the shift light to 8000 rpm: Press the button four times. The check engine light will flash four times quickly, with a one second pause between groups of flashes. Tap the brake pedal. The check engine light will start to flash the thousands of revs. Press the button eight times, so the check engine light flashes groups of eight (8000 rpm). Tap the brake pedal. The check engine light will start to flash hundreds of revs. Tap the brake pedal without pressing the button. The shift light is set to 8000 rpm.
Rev counter accuracy
The static method used to determine the engine speed is very accurate, usually much more accurate than the rev counter which can be between 5 and 10 % out. The rev limits that you set will often be different from that shown on the rev counter.
