| The Translator Pro controls turbocharger boost by operating the solenoidwith a 'Dutycycle', which is the ratio of the time the solenoid isenergized, to the time it is off. 100% Dutycycle means the solenoid isfull on. 50% Dutycycle means the solenoid is being turned on and offwith equal timing. 10% Dutycycle means that the solenoid is on briefly,then off for much longer. Refer to the instructions included with thesolenoid when installing the solenoid. The Translator Pro controls boost as follows: During normal driving,the solenoid is not activated. When the Throttle and RPM thresholds areexceeded, Spool mode is activated, and the solenoid is fully energized(100% dutycycle) which prevents any pressure from passing thru thesolenoid and causes the turbo to spool as quickly as possible. Once theboost pressure exceeds 'PSI Start' the solenoid is operated at the 'StartDC%'. If the boost pressure exceeds the desired target boost 'PSI Set'(or 'PSI Aux' if the Aux input is activated) the solenoid dutycycle isreduced at a rate determined by the 'Gain' setting. The solenoiddutycycle will only be increased to raise the boost if the throttle positionexceeds 'TPS Start' The Translator Pro can control the boost pressure to a desired setting aslong as a MAP sensor is connected to the unit. Adjust the Boost Controlparameters as follows: | ||||||
| Selection | Description | Default | My Settings 1 | My Settings 2 | My Settings 3 | Notes |
| TPS Spool | Throttle sensor voltage to enable Boost Control. Usually adjusted to 1.25 - 2.5 volts. Lower settings can improve spoolup time. Higher settings can reduce part throttle surge. It should be set higher than typical cruising TPS voltages. | 2.500 | ||||
| RPM Spool | Engine RPM to enable Boost Control. Set higher than typical cruising RPM. | 2400 | ||||
| TPS Start | Once Boost control has started, TPS must exceed than this for the system to increase solenoid duty cycle. Set this to about 80% throttle. If it is set too low, the Translator Pro will attempt to raise the boost pressure as the driver 'backs out' of the throttle. If the driver were to floor the throttle again a boost spike could occur. | 3.700 | ||||
| PSI Start | Boost pressure at which the system changes from Spool mode (solenoid full on) to Start mode. Set this half way between the base boost of the vehicle and the desired boost. If boost overshoots are excessive, reduce this setting. If boost overshoot is desired, set this closer to the target boost. | 5.0 | ||||
| DC% Start | The Solenoid dutycycle that is set when spool mode completes. The approximate setting to start with is(1-(base boost/target boost))*100. First tests should start with about half of this. Example, base pressure = 10 psi, target boost = 18 psi. Estimated Dutycycle =(1-(10/18)) * 100 = 44%. So start at 22% for initial testing. | 10.0 | ||||
| PSI Set | Boost Pressure the system will try to maintain | 10.0 | ||||
| PSI Aux | Boost Pressure the system will try to maintain when the Aux Trigger input is activated. | 10.0 | ||||
| Gain | How fast the system will change the solenoid dutycycle to try to adjust the boost. Set this only high enough to achieve good boost control. Too much gain will cause the boost to surge/oscillate. Setting the Gain to 0.0 will prevent the system from adjusting the solenoid to control boost. | 4.0 | ||||
| DC% St Aux | The Solenoid dutycycle that is set when spool mode completes and Aux mode is activated. | 10.0 | ||||
| Max RPM | 0 | |||||
| The Translator Pro can control WOT AFR to a desired setting using feedback from a wideband AFR sensing device. Install the wideband sensor in the exhaust following the manufacturer's instructions. Connect the Translator Pro wideband/O2 input to the analog output of the wideband unit. Connect the wideband/O2 sensing ground to the wideband ground. (use the 'analog ground' if the wideband has one, or connect to the wideband main ground, close to the unit) The wideband/O2 sensing ground must be connected or the wideband signal will not be measured correctly. The wideband input on the Translator Pro is a 'differential input' and measures the difference between the input and the sensing ground. Set the AFR Source in the Config page to match the wideband unit installed. Setup or program the wideband unit if required. When the wideband unit is installed and operating the analog voltage can be monitored on the O2 parameter of the Sensor Monitor page, and the AFR is also viewable. Ensure the AFR displayed matches the wideband unit. In order for AFR tracking to be active ALL parameters must be met. NOTE: 'AF TrDelay' (setting number 11) located in the 'System Setup' menu controls the amount of delay before AFR Tracking is activated once the required parameters have been met. | ||||||
| Selection | Description | Default | My Settings 1 | My Settings 2 | My Settings 3 | Notes |
| Min TPS | TPS above which the AFR tracking is enabled. Set this high enough to ensure the ECU will be operating Open Loop whenever AFR tracking is enabled. To disable AFR Tracking set this setting to a range above that of your TPS when the throttle is open all the way. For example, if your TPS reads 3.50v when you have the pedal pressed all the way down, set Min TPS to 3.60v or higher. | 4.900 | ||||
| Min RPM | RPM above which the AFR tracking is enabled. Set this high enough to ensure the ECU will be operating Open Loop whenever AFR tracking is enabled. Another way to disable AFR Tracking would be to set this setting higher than your engine will rev. | 3200 | ||||
| Min Load | Manifold pressure above which AFR tracking is enabled. Set this high enough to ensure the ECU will be operating Open Loop whenever AFR tracking is enabled. Yet one more way to disable AFR Tracking would be to set this setting to something higher than your engine will see. | 166.4 | ||||
| Lean Lim% | The maximum % that the system will lean out to maintain the desired A/F. It is advisable to set this around 5%, so the AFR will not go incredibly lean if there is a problem with the wideband unit. | 10.0 | ||||
| Rich Lim% | The maximum % that the system will richen up to maintain the desired A/F. This can be fairly high (25%) to help protect the engine in case of a fuel system partial failure. | 10.0 | ||||
| Gain | The speed that the system will try to maintain the desired A/F ratio. Start with 5, and test the operation of the tracking. Setting this too high will result in unstable AFR and a system that oscillated | 4.0 | ||||
| AFR 2000R | Desired A/F Ratio at 2000 RPM | 11.5 | ||||
| AFR 3000R | Desired A/F Ratio at 3000 RPM | 11.5 | ||||
| AFR 4000R | Desired A/F Ratio at 4000 RPM | 11.5 | ||||
| AFR 5000R | Desired A/F Ratio at 5000 RPM | 11.5 | ||||
| AFR 6000R | Desired A/F Ratio at 6000 RPM | 11.5 | ||||
| AFR 7000R | Desired A/F Ratio at 7000 RPM | 11.5 | ||||
| AFR 8000R | Desired A/F Ratio at 8000 RPM | 11.5 | ||||
| Aux% | Change to target AFR when Aux is activated. | 0.0 | ||||
| Air temp correction, setting is added to the regular system tune value. ***Note this adjustment is in addition to the Speed Density algorithm's temperature compensation. Additional adjustment can be required to adjust for atomization characteristics of injectors, or heat-soak conditions. | ||||||

| Part-Throttle A/F Tracking or PTT is a feature which allows you to set the MAFT Pro to attempt to maintain a certain AFR under specified conditions. Commonly this feature is used to lean out the fuel mixture under low stress conditions to improve fuel economy. If you're rather creative there are a couple other possible applications, but you'll have to figure those out on you're own as they're not recommended. ;) NOTE: To use this feature your ECU MUST be operating in Open Loop and you MUST have a compatible wideband installed and operational. | ||||||

| Idle TPS | The specified voltage the TPS must be below for PTT to actively adjust for the specified AFR. If your TPS voltage at idle is typically .50v you want to set this parameter for at least .51v to enable PTT for Idle or set it lower than your TPS voltage goes to disable it. | 0.0 | ||||
| Idle RPM | This is the maximum RPM under which PTT will adjust for idle. If your vehicle typically idles at 760RPM and this is set for 780RPM PTT will adjust for your regular idle but may not adjust for your engine's cold idle. Setting this for a level between your cold idle and your regular idle may help while the engine is warming up. | 640 | ||||
| Idle A/F | Your desired Air to Fuel Ratio while the engine is at idle. | 13.5 | ||||
| Cruise TPS | The specified voltage the TPS must be below for PTT to actively adjust for the specified AFR. If your TPS voltage while cruising reaches 3.51v (just for an example) you want to set this parameter for 3.51v to enable PTT for Cruise or set it lower than your TPS voltage at idle to disable it. Generally you want to add a little buffer to this parameter to ensure that PTT enables under cruise conditions, so you may want to add a little overhead and set it a little higher. | 0.000 | ||||
| Cruise RPM | This is the maximum RPM under which PTT will enable for Cruise. If this is set to 2500RPM, PTT will be disabled once the RPMs go higher. | 2560 | ||||
| Cruise Load | This is the cap for the Cruise PTT. If your load goes above this setting the MAFT Pro will stop trying to maintain the Cruise A/F. | 91.0 | ||||
| Cruise A/F | The target A/F when PTT is operating and adjusting for Cruise. | 14.5 | ||||
| Lean Load | This is the cap for the Lean PTT. If your load goes above this setting the MAFT Pro will stop trying to maintain the Lean A/F. | 130.0 | ||||
| Lean Delay | This specifies the amount of time delay before the MAFT Pro will switch from adjusting for the Cruise AFR to the Lean AFR. | 15.0 | ||||
| Lean A/F | The target A/F when PTT is operating and adjusting for a Lean Cruise. | 16.0 | ||||
| Gain | This controls how agressively the MAFT Pro attempts to adjust the fuel to reach the desired AFR. | 11.5 | ||||
| Enabl. Dly (added as of v4.89) | This parameter sets the amount of time before PTT is enabled once the required parameters are met. | |||||
| ETPS RPM (added as of v5.x) | The RPM trigger value for the Enhanced TPS function. When this feature is active the MAFT Pro receives the signal from the TPS. The MAFT Pro then supplies the signal to the ECU unchanged. Once either trigger value is reached the MAFT Pro switches from sending the actual TPS voltage to sending the value specified in 'V-Out(x) Max' in the Setup Menu. The signal is sent to the ECU via either V-Out1 or V-Out2. To disable set this value to a higher level than your setup will achieve when operating. | |||||
| ETPS Load (added as of v5.x) | The MAP Load trigger value for the Enhanced TPS function. When this feature is active the MAFT Pro receives the signal from the TPS. The MAFT Pro then supplies the signal to the ECU unchanged. Once either trigger value is reached the MAFT Pro switches from sending the actual TPS voltage to sending the value specified in 'V-Out(x) Max' in the Setup Menu. The signal is sent to the ECU via either V-Out1 or V-Out2. To disable set this value to a higher level than your setup will achieve when operating. | |||||
