| Turbonator Features: | |
|---|---|
| 1) Knock Indicator – [ALL] This feature flashes the ‘Check Engine’ lamp whenever the timing is being retarded due to knock. It’s a useful feature to feedback to the driver when you should back off to save your engine. | To enable this feature, go to ‘Setup’, ‘Cal Configuration’, ‘CalCustomOptionsConfig1’ in the MP Tune editor window. Check the box for ‘Flash CE on Knock’. It’s now turned on. The only config option for this feature is the coolant temp cutoff. You can specify the minimum coolant temp to allow this feature to operate. Generally, you can get false knock at low coolant temps. |
| 2) Switchable boost – [ALL] This allows a ‘LOW’ boost setting to be used when a switch is applied. Unfortunately, it must be one of the existing inputs to the SMEC (Cruise, A/C, P/N switch, etc.). But, these can be ‘doubled up’ – IE, you can have the cruise on/off switch work for both hi/lo boost as well as cruise. This is similar in operation to the S60 boost switch feature, though without the timing adjustment for low octane fuel. | To enable this feature, go to ‘Setup’, ‘Cal Configuration’, ‘CalCustomOptionsConfig1’ in the MP Tune editor window. Check the box for ‘Switchable Boost’. It’s now turned on. The only config options for switchable boost are the ‘Lo’ boost setting – ‘Boost Control’, ‘Target Lookup’, ‘AllowedBoostLo’. This is a constant value and is not dependent on any other factors. And, the boost switch – ‘Boost Control’, ‘Target Lookup’, ‘HighBoostSwitchSelect’. |
| 3) Staging Limiter (2-Step) – [ALL] This feature allows a lower than normal rev limit to be set. This lower limit can be enabled by a low speed cutoff (usually 2-10mph), and/or a switch (usually the brake switch for auto cars). The lower rev limit is useful for launching the car in a drag race. | Staging Limiter (2-Step) Spark-Cut Rev Limiter Anti-lag Retard The 3 features above can be used together for the SMEC and SBEC cals to create a very comprehensive launch control feature. |
| 4) Spark-Cut Rev Limiter – [SMEC/SBEC Only] Added the ability to specify a spark-cut to be used for the rev limit instead of a fuel-cut (which is the stock operation). When used in conjunction with the staging limiter, this gives much more precise control of the RPM while staging. The fuel-cut typically has a ~500rpm swing. The spark-cut staging limiter can get down to ~200rpm. If desired, it is also possible to configure the spark-cut limiter for ‘bang-bang’ operation. | Staging Limiter (2-Step) Spark-Cut Rev Limiter Anti-lag Retard The 3 features above can be used together for the SMEC and SBEC cals to create a very comprehensive launch control feature. |
| 5) Anti-lag Retard – [ALL] Anti-Lag is a feature that helps spool the turbo. For the latest release of T/SMEC and T/SBEC, anti-lag has been completely re-written. Previously, anti-lag retarded the timing proportionally to the difference from boost target. Now, the Anti-lag timing is a pre-set value and it only works during staging (though, it will work with either the spark-cut or fuel-cut limiters). The anti-lag/staging advance can be set anywhere from -16 to +16 degrees. | Staging Limiter (2-Step) Spark-Cut Rev Limiter Anti-lag Retard The 3 features above can be used together for the SMEC and SBEC cals to create a very comprehensive launch control feature. |
| 6) Alky Injection – This feature is available, but not included in the standard build. Please PM me if you are interested in using it. Due to space and time limitations, I commented it out. But, it can easily be re-enabled for those that are interested. | |
| 7) Customized Boost Control – [SMEC Only] Added some custom code and an additional table to modify the WG duty Cycle as an anti-lag measure. Basically, the WGDC is set to 100% during transients to keep the WG from seeing the manifold pressure and releasing the exhaust gases early. | |
| 8) Modified Dwell Calculation – [SMEC/SBEC] Added Dwell compensation for battery volts. This will maintain better dwell control than the stock code. Should improve ignition performance at WOT (when the alternator shuts off and battery voltage can drop). This feature is enabled in all cals. | The modified dwell calculation is built into every cal and is not configurable. However, the Dwell Time vs. battery volts table is available for adjustments if needed. It’s not recommended to adjust this table unless you are sure about what you are doing. |
| 9) Lock-up solenoid operation – [SMEC/SBEC] Added PTU capability to the SMEC codebase. This is the exact same functionality as the stock 3.0 and later 4-cylinder turbo and TBI ECU’s. (included on the factory cals for the SBEC) | |
| 10) Decel Fuel Cut – [SMEC/SBEC] This will cut fuel (completely) on decel for fuel economy improvement. Currently only works on MT trans cals.(included on the factory cals for the SBEC) | |
| 11) WB2NB – [SMEC/SBEC] This is a feature that will allow you to feed a 0-5v WB signal directly into the SMEC thru the existing O2 sensor input. The code will automatically convert the signal to a NB range for use in the stock feedback mechansim. The WB AFR is stored in RAM so that it can be read and logged using MP Tune. There is also a constant value that can be used to offset the entire NB signal to force the engine to run richer or leaner in feedback mode. | WB2NB Setup |
