G37 Supercharger Tuning
There are all sorts of configurable options with the new Ecutek software used to tune our car. The modified traction control was a huge plus for us. Even with normally aspirated power the factory traction control was worse than a DMV instructor from a foreign country. Even with moderate power applied the traction control nanny would pull all power and letting off and re-applying power would repeat the same scenario. It was super dangerous before and even with the linear power a supercharger delivers we assume it would be even more intrusive. With our new boosted power the ECU pulls just enough throttle to surf the edge of the tires traction. The slip light still fires off to let you know its working.
Another plus is the Ecutek Bluetooth interface that works with a smartphone app. Among many options is the ability to have a configurable dashboard of gauges. There are simply too many to list but it’s a plus for those that don’t want to bother with the hassle of adding gauges. Also each one of the maps that Specialty Z configured for us can either be switched via the cancel button on the steering wheel or the application on your smartphone.
The other big feature though the app is datalogging. For those times you just don’t want to have to lug a laptop in the car using the OBD2 interface you can use the app. Simply select the datapoint(s) you want to capture and start the logging. It creates a .csv file you can read through or pass on to your tuner. For us it would be a great thing to look at if we think we’re getting close to detonating to measure the knock count coming back to the ECU.
We’ve got some homework to do there with these datalogs as we watch the air temps climb in the summer. Sebastian said to look for how much ignition advance is pulled. One to two degrees is okay but four degrees is the limit. Zero is obviously best but there are also false positive knocks (things that sound like detonation but aren’t) that also pull ignition advance and kill power.
There’s more power for us when we decide to start playing around with e85. Specialty Z sells a flex fuel kit we’ll be sure to add when the time is right. For now we’ll be enjoying the new found power. We’ll be turning our attention to some ancillary items like a boost gauge, motor mounts and additional bracing.
