Congratulations! You have purchased the ACCEL TIMING RETARD MODULE. This unit can be programmed to automatically retard your engine’s ignition timing or four different inputs. When not being programmed, your ACCEL TIMING RETARD MODULE functions as a digital retard meter. Use ACCEL 300+ RACE WIRE spark plug wires! Solid-core spark plug wires emit RFI and EMI static, which can disrupt On-board electronics. Do not use your TIMING RETARD MODULE with another timing control module.
THE ACCEL TIMING RETARD MODULE - AN OVERVIEW Your new ACCEL TIMING RETARD MODULE is a computer module. It is meant to be installed etween your ignition triggering device (distributor pickup, crank trigger, etc.) and your gnition module. It controls the signals that tell your ignition when to fire. n addition to its trigger input, your ACCEL iming Retard Module uses four external nputs to activate timing retard values. he four inputs may be connected to any ype of switch to activate selected retards.
PRECAUTIONS AND WARNINGS The ACCEL Timing Retard Module will cause a small, fixed timing retard in the trigger. This is due to computational delay. Engine ignition timing must be checked, and re-adjusted, to account for this delay after your timing retard module is installed. This flexible product makes it easy to select values that can damage your engine. Start by selecting safe values. Carefully evaluate their effect. Make small changes, when changing values, and use caution.
1. With the unit powered off press, and hold down, both the SAVE and CRANK buttons. 2. While holding those two buttons down, apply power to the module. The module will enter its Programming Mode and display a number that represents the number of cylinders in an engine (the factory default). 3. Use the ⇑ and ⇓ keys to select the number of cylinders for YOUR engine. 4. When finished, press SAVE. This stores this new information and puts the module back into Control Mode operation.
When connected to an H-Pattern, manual transmission, your Timing Retard Module’s 1st, nd, and 3rd keys each program how much retard takes effect when one gear is selected. nstall switches on the shifter that, when closed, signal the module that a gear is engaged. When the ACCEL Timing Retard Module receives its signal it adjusts timing retard to e value you have programmed for that gear. ypically the 3rd key, and its switch, is attached to p gear.
WIRING AND PROGRAMMING A LENCO-TYPE SHIFTER here are major differences between the Lenco gearbox and shifter, and an H-Pattern manually shifted transmission: • The Lenco box accumulates gear ratios. Higher gear’s ratios are the total of the lower gear shifts. • The Lenco has a stick for each gear. Before shifting into a high gear, all lower gears must be engaged. i.e. To be in 4th gear, the 3rd AND the 2nd gear sticks must also be thrown. • When you are moving forward 1st is always engaged.
HE 2-PIN, INPUT CONNECTOR (Main Power) This is the main power input for your ACCEL Timing Retard Module. Its BLACK wire is Grounded and its RED wire inputs +12 VDC from the battery. (not more than +18 VDC or less than +8 VDC) The RED wire connects to the battery through the power or key switch. In general, the best place to Ground the BLACK wire is on the engine. Make sure that rubber mounted engines are well Grounded.
WIRING GEAR SHIFT SWITCHES lthough programming may be different for Automatic, H-Pattern, or Lenco type transmissions, the way you place and connect their switches will probably be similar. nfortunately gear shifts come in many different shapes, and we cannot tell you which ind of switch you should use. You’ll have to choose and attach your own switch.
LED’s do not display A timing light does not show he programmed value Tachometer does not work Your ACCEL+ sparks randomly Status Light on Your ACCEL+ is Dim Status Light on Your ACCEL+ is OFF Timing doesn’t hange when car is in a new gear The Timing Retard Module is not getting power. Check the 2-Pin connectors’s Red and Black wires. See Pg 10. The engine was not retimed when the Timing Retard Module was originally installed, or the wrong number of cylinders was selected Time the engine again. See Pg 3.
QUICK REFERENCE Adjusts how much Retard takes effect when you first start your engine. Press the CRANK button and adjust the value with the ⇓ or ⇑ buttons. Cranking Retard only takes effect below 600 RPM. (See Pg 5) Sets how much Timing Retard will take effect when Switch #1 is ON. Press the 1st button and adjust the value with the ⇓ or ⇑ buttons. The Module senses through the YELLOW wire when Switch #1, on the shifter, is CLOSED, and Retards by the amount designated.
ACCEL TIMING RETARD MODULE COMPATIBILITY CHART ACCEL SUPER COIL PART # 140009 ACCEL DRAG RACE COIL PART # 140010 Any of the ACCEL+ ignition systems, in this case an ACCEL 300+. 3-STAGE REV-LIMITER # 49345 CCEL ART ACCEL TIMING RETARD MODULE PART NUMBER - 49355 Your ACCEL TIMING RETARD MODULE connects directly to any Capacitive Discharge ignition system. If it is connected through an ACCEL 3-STAGE REV-LIMITER, it outputs to the ignition through the Rev-limiter.
ACCEL+ TIMING RETARD MODULE rag Racers must be able to launch off the line hard, with MAXIMUM TIMING ADVANCE. eat, caused by combustion, can cause engine damaging “Detonation”. Retarding ignition ming can prevent detonation. The ACCEL+ TIMING RETARD MODULE has been specifically esigned for this purpose. Your new ACCEL+ TIMING RETARD MODULE can also adjust gnition timing retard for single or multi-stage Nitrous.
