Microtech LT10s QUICK START UP GUIDE Parameters - Normal Mode, Fuel Only, PULP, Naturally Aspirated, MAP load This information is intended and provided as a quick reference guide only. Microtech Operator manual should be read in full and understood before attempting to tune the ECU to suit your Engine. Step 1
SET TPS – This Step must be done BEFORE ENGINE IS STARTED • Scroll to TPScal (Screen 30 on Handset) • Set Idle Speed Screw • With foot OFF Throttle, Adjust Up/Down until TPS reads 0(zero) Yellow light will appear on ECU when TPS is calibrated correctly
Step 2
TUNE IDLE – Set idle speed and adjust Up/Down for smoothest idle Scroll to Idle (Screen 1 on Handset) Set Idle Speed Screw Adjust Up/Down to achieve best idle and emissions. Black Smoke (Too Rich) Adjust Pulse Width Down Hunting (Too Lean) Adjust Pulse Width Up

TUNE OFF IDLE – Adjust this section with NO load on the engine. Adjust first 3 vacuum section for best Throttle response and target AFR is achieved. Scroll to Load (Screen 8 on Handset) TARGET AIR/FUEL RATIO 14.7-13.5 AFR < 13.5:1 (Too Rich) Adjust Pulse Width Down AFR > 14.7:1 (Too Lean) Adjust Pulse Width Up With light throttle rev engine to 2000rpm and adjust 25”, 20” 15”Hg Sections until engine clean revs and target AFR is achieved. TUNE LOAD MAP – Should be done on a Dyno or open deserted road. Run engine under load or up a hill at 3000rpm and adjust 10”, 5” & 0”Hg sections until target AFR is achieved. TARGET AIR/FUEL RATIO 13.5-12.5 AFR < 12.5:1 (Too Rich) Adjust Pulse Width Down AFR > 13.5:1 (Too Lean) Adjust Pulse Width Up Under load rev engine to 3000rpm and adjust 10”, 5” & 0”Hg until target AFR is achieved
Once you are satisfied with the results from Step 1-4 it time to fine tune your engine.

TUNE WOT – This function is set under full load / wide open throttle. This task is best completed on a dyno. The mixture is corrected every 500rpm from 500-9000rpm. TARGET AIR/FUEL RATIO 12.0-12.5 AFR < 12.0:1 (Too Rich) Adjust Pulse Width Down AFR > 12.5:1 (Too Lean) Adjust Pulse Width Up Scroll to RPMwot (Screen 17 on Handset) Adjust pulse width every 500 rpm until target AFR is achieved
• •
TUNE CRUISE – This function is set under cruise / light load conditions. This will provide better Fuel Consumption during cruising and highway driving. The mixture is corrected every 500rpm from 500-9000rpm. TARGET AIR/FUEL RATIO 14.2-14.7 AFR < 14.2:1 (Too Rich) Adjust Pulse Width Down AFR > 14.7:1 (Too Lean) Adjust Pulse Width Up Scroll to RPMcrs (Screen 18 on Handset) Adjust Pulse Width every 500 rpm until target AFR is achieved

TUNE ACCELORATOR PUMP – This section improves throttle response and removes flat spots in the tune. # Note: Select suitable gear to provide longest test without bogging the engine down. Scroll to Pump1 (Screen 19 on Handset) – Idle-2000rpm Apply Full throttle from near idle speed while rolling - # 2nd Gear Decrease the Pulse Width in small increments – Repeat Test until you note a definite hesitation Increase Pulse Width to next highest value with NO hesitation Scroll to Pump2 (Screen 20 on Handset) – Over 2000rpm Apply Full throttle from 2000rpm while rolling - # 3rd Gear Decrease the Pulse Width in small increments – Repeat Test until you note a definite hesitation Increase Pulse Width to next highest value with NO hesitation ENJOY THE PERFORMANCE ONLY EFI CAN OFFER
