Congratulations on purchasing the most advanced aftermarket chip available for the Syclone/Typhoon. This chip is actually a timing and boost controller, as well as a vehicle anti-theft system all in one package.
Installation: Installation is the same as described in the Multichip instructions. The only difference is the placement of the display/switching unit. This can be placed anywhere the user finds convenient in the vehicle, and can be secured using velcro tape if desired. The ribbon cable can be disconnected from inside the display/switching unit by removing the two bottom Phillips screws and lifting the bottom half of the enclosure. You will see the connector holding the ribbon cable which can be lifted and removed. This step will allow you to disconnect the display from the chip carrier in instances where installation requires the cable to be run though a small opening or drilled hole. Suggested locations are under the ashtray, under the side view mirror adjuster, or on top of the dash where it is easily accessible and viewable.
Operation: Once installed, operation is very straightforward. Press the push-button switch to toggle through the various programs. The display will indicate the current level of timing and boost, or any special settings contained in the chip, such as security (SEC) or valet (VAL). The timing is indicated by the first two digits, as T1, T2, or T3. The larger the number, the more advance in the program. T1 is a level similar to that of the stock calibration, and will be safe to use with 93 octane fuel at boost levels of 17psi and below on a stock vehicle. T2 has a couple more degrees of advance, throughout the rpm range and may require more than 93 octane, even at the lower boost levels. On vehicles with upgraded turbos and/or intercoolers, the lower boost levels of the T2 timing might be safe to run with 93 octane. This is up to the user to determine by monitoring knock, as it will vary from vehicle to vehicle. T3 has a couple more degrees advance than T2 and will require additional octane to run safely.
The boost level is indicated by the second 2 digits of the display, as the value in PSI (16, 17, 18, etc.) Note that the 24 psi programs will drop approximately 1 psi at WOT above 4800 rpms, to 23 psi. For those with stock turbos, keep in mind the limits of this turbo. The boost levels above 20 psi might not be reached due to the small flow characteristics of the stock unit. Also, due to its inefficiency above 20 psi, horsepower gains will probably be minimal above this level even if you are able to attain them.
The 2 position key switch is used to enable or disable program selection. With the key switch in the 12 O’clock, or CW, position, the push-button switch is active and all programs can be accessed. In the 9 O’clock, or CCW position, the push-button switch becomes inactive and the unit will remain in it’s last selected position until the key switch is back in the 12 O’clock or CW position and all programs can be accessed once again.
Programs can be selected or switched at any time the vehicle ignition is on. The display/switching unit requires power to operate and will not change programs without being powered up.
The best method of setting the security (SEC) program is to shut the vehicle off in whatever mode you were using, then turn the ignition on with engine off and toggle to the SEC program. Turn the ignition off again. Turn the keylock to the 9:00 O’clock position before leaving the vehicle to disable the unit. To start the engine again, turn the keylock to 12:00 O’clock, turn on the ignition with motor off, and toggle to the desired program. Vehicle will start in a normal manner at this point.
The Valet (VAL) program is a part throttle only program. It has a rpm limit of 4000, no intercooler pump operation, and significantly reduced timing. If an attempt is made to run at WOT (wide open throttle) the truck will sluggishly accelerate to 4000 rpms, then hit the rpm limit, shutting off the injectors. The truck will behave normally during all other operating conditions.
Programs are accessed sequentially in this order: SEC, VAL, T1-15, T1-16, T1-17, T1-18, T1-20, T1-22, T2-17, T2-18, T2-20, T2-22, T3-18, T3-20, T3-22, T3-24. Programs cannot be accessed in the reverse order, therefore it is best to shut off the engine when going from the higher timing programs to lower due to the fact that the SEC program must be accessed in order to get to these programs. However, if you can hit the pushbutton fast enough when reaching the SEC setting, you can get past the shutdown mode of the security program before it cuts off the engine. It is still recommended though that the engine be shut off first before toggling past the SEC program.
