Crrect Step 4 Nzzle Munting Incrrect Step 2 Test Cntrller With the nzzles remved frm the intake, place the cntrller in bst nly mde by disabling the EGT Cntrl mde. Set gain t 100. Discnnect the silicne bst line frm the bst T n the intake plenum bst line. Using a hand pump, apply 10-20 psig f pressure t the bst line leading t the cntrller. Pump shuld activate, fluid shuld flw, and tank level shuld g dwn. Tuning Quick Reference If cmbustin quench ccurs as evidenced by engine bucking, reduce the injectin quantity. This can be dne by: The nzzle assembly shuld be installed 90 t the directin f airflw. On the 5.9l the preferred lcatin is the back f the air hrn (see pht). Chse and mark munting lcatin Remve selected piece and drill and tap (11/32" pre-drill, 1/8-27 NPT tap) fr ne r tw nzzles. The nzzle is munted using its external 1/8 NPT threads. Tighten the nzzle and nzzle hlder assembly ne half turn past finger tight using E6000 t seal the threads. 1. Using a smaller nzzle(s). 2. Using Screen 10 and Screen 11 t adjust the gain. Cautin****** Prlnged quench may cause lwer engine damage ver a perid f time. Als, fresh methanl less than 1 mnth ld when expsed t atmsphere and using a greater methanl cncentratin up t 50% - will reduce cmbustin quench. 100% water will cl cmbustin and EGTs and will increase pwer apprx 20-30 HP. 75/25 water/methanl will reduce EGTs and pwer will increase apprximately 40 HP. 50/50 water/methanl will reduce EGTs and increase pwer apprximately 70+ HP. Cautin: T avid pling in the intake it is recmmended that: 1. The engine be run withut water/methanl fr at least 5 minutes after injectin befre turning the engine ff. 2. The armed switch is turned t the ff psitin when the engine is ff.
Remve tubing frm nzzle (r slenid if slenid used in-line between pump and nzzle) and run tube int separate cntainer. Apply 12 VDC t red pump wire fr apprximately 5 secnds r until fluid flw is cnsistent. Be sure t discnnect cntrller befre htwiring pump. Pump is nw primed. Recnnect tubing frm pump utlet t nzzle (r slenid). If using a slenid in between the pump and the reservir: Remve the slenid and place a slid piece f tube between the pump and the reservir and prime the system. Then replace the slenid in between the pump and reservir. Addendum fr 6.7L Cummins Applicatins: Nzzles are munted in the black plastic tube that cnnects the intercler-t-intake lcated n the driver s side f the engine. Step 1. lsen clamps that attach tube t cast elbw and intercler. Step 1 Test Pump and Mechanical System Discnnect pump frm cntrller. Using a 12 vlt surce, apply pwer t red wire f pump. Pump shuld activate and fluid level in tank shuld g dwn. It is recmmended t als check the nzzle spray pattern while fllwing this prcedure. Als check fr leaks. Step 2. Pry rubber bts ff intercler and cast piece. Step 3. Slide tube ut frm tp and mark, drill and tap fr nzzles. If pump ges n and fluid level desn't g dwn, there is an bstructin in the tube r nzzle. Activatin f pump fr shrt perids (1-5 sec.) will purge air bubbles frm the system. This can be accmplished during initial use f the system. Tip: Munt nzzles apprx 3 apart s spray is 90º t airflw. Tip: T make sure there is n pling f fluid while injecting, make sure nzzle tip is at least flush with the inside f the tube when tightened. Step 5 Nzzle Cnnectin and Slenid Cnnectin Slenid is flw directinal. Be sure t nte which prt is the INLET/PRESSURE prt (2 r IN) and which is the OUTLET prt (1 r OUT).
The main utlet line cming frm the Reservir cnnects t the slenids inlet. The utlet f the slenid cnnects t the inlet f the pump. Measure the distance frm the pump utlet t the nzzle hlder. Cut the ¼ tubing using utility knife. Make cuts are as square as pssible. Ensure there are n kinks in the tubing and insert tubing int quick discnnects until fully seated. Gently pull n tubing t ensure a gd cnnectin. Use tie wraps t help rute tubing and t ensure it desn't cntact mving r ht parts in the engine cmpartment. Have tubing cnnect t quick cnnect fittings at shallw angles. Having an immediate sharp bend may unseat the tubing frm the internal -ring and create a leak. Cntinual insertin and remval frm quick cnnect fittings will mar the end f the tubing. Over time the internal gripping teeth may lse their hld f the tubing which may create a leak. If this ccurs simply remve the tubing and make a fresh cut using a razr blade. Step 6 Install EGT Prbe Drill and tap exhaust manifld pre-turb. If this is perfrmed with the exhaust manifld still n the engine, start the engine and let it idle while drilling and tapping. This will prevent shaving frm entering the exhaust and turb. During tapping, cat tap with heavy grease s it will cllect any metal shavings. Variable Cntrller Tuning EGT Cntrl Mde When EGT Cntrl mde is enabled, the cntrller will measure EGTs and bst pressure t calculate the injectin rate. This is ideal in heavy lad and twing situatins. In this mde, a high gain setting will result in a larger injectin rate. Tggle t Screen 8. Set EGT Cntrl t ON. Tggle t Screen 10. Adjust the gain up t 100. If cmbustin quench ccurs as evidenced by engine bucking, reduce the injectin quantity r lwer the gain setting n the mdule. This can be dne by: Using a smaller nzzle(s). Adjusting the gain. T adjust gain dwn, tggle t screen 11. Adjust the gain dwn until engine runs smth with n bucking. Bst Only Mde The cntrller has a bst nly mde. When EGT Cntrl mde is disabled, injectin is a functin f bst pressure nly which is desirable in racing applicatins and day t day unladed driving where mre immediate injectin is desired. Tggle t Screen 8. Set EGT Cntrl t OFF. If cmbustin quench ccurs as evidenced by engine bucking, reduce the injectin quantity r lwer the gain setting n the mdule. This can be dne by: Using a smaller nzzle(s). Adjusting the gain. Selecting a higher bst range. T adjust gain dwn, tggle t screen 11. Adjust the gain dwn until engine runs smth with n bucking. Testing the System Nte: fr best results, prime pump befre use Munt the Temp Prbe using the 3/16 cmpressin fitting (prvided). T clear air frm the pump and insure that the system is primed: Fill reservir with water apprx ¼ full.
