RIPP Supercharger JEEP Wrangler 3.8 Trouble Shooting Guide: This is a reference guide to help you tech any issues you may encounter during or after the installation. The following are the most common teched and resolved. No start (Includes long crank-no start): Make sure the ECU plugs are pushed in all the way, it’s an easy thing to over look and the simplest solution. Make sure black box is plugged in Check fuses; if there is a no start situation it could be a blown fuse. If a fuse is blown it could have happened during installation and went unnoticed. If it blows again there is a direct short somewhere, trace your steps. The red power wire would be a good place to start. Check wiring; there are two cut through wires, the crank sensor and the map sensor. These signals are filtered through our electronics for tuning purposes. It’s very easy to confuse these two wires or pick the wrong wire to hook up to. If there is a no start situation it’s most likely the crank wire mixed up. Running rough and Check Engine lights: Make sure the air temp sensor wires are hooked up correctly. Double check correct wires in corresponding pin locations, this is the most common mistake and most likely the issue. Make sure Vacuum lines are hooked up correctly to MAP sensor. The MAP sensor needs to see vacuum and boost to work correctly. Make sure all vacuums are sound Make sure PCV valve is correctly installed, if backwards you will pump boost directly into the crank case. This will blow every seal out, examples being valve cover gasket. Make sure your spark plug wires are snug Do not use ANY other electronic power mapping such as the high octane setting in a Hypertech Max Energy Programmer. This will conflict with the Black Box mapping and cause run faults. Tire size calibration: Use only Hypertech Products to calibrate tire size. RIPP does not endorse any other brand. This step is essential, just because your tire advertises to be XX size doesn’t mean the tire is actually that size. Please follow the tire size calculator instructions supplied with your speedometer calibrator. Many tires that claim to be 35” high will in actuality be 33.5 by way of equation. Please make sure this step is properly administered. Run faults will occur. Running Lean: Check supplemental Injectors are triggering. The use of a noid-light would be best. Under no circumstances should you ever hook up an LED or other type of light to the injector wires or plugs. This will be interpreted as a short as blow the injector triggers in the Black Box. Make sure you have proper vacuum and boost going to supplied MAP sensor. Too much Methanol spraying Methanol mix ratio is off No Power: Make sure you are not flooding the engine with methanol, make sure you have proper vacuum and boost going to the supplied MAP sensor Excessive detonation: Make sure you are triggering the supplemental injectors; make sure you wired your Black Box up correctly. 27
