Increase air/fuel ratio at the lower RPM's (a richer mixture creates more exhaust heat and will spool turbo faster) Increase timing at lower RPM's (will create more power-More power more exhaustfaster spool.
Does apr tune make turbo spool earlier driver#
Lastly, advanced high-output protection routines are enabled, allowing the ECU to make constant adjustments to airflow and fuel to cool and protect the engine, all without the driver knowing otherwise. Switch to Numerically lower rear end gears. How does ignition timing affect how a turbo spools up I road tuned backed off 3 degree timing from -4 vac to 8psi turbo seems to spool up much quicker. Mastery of the boost control system makes for an impressively predictable driving experience as the turbo spools quickly, delivering instant power, while torque-by-gear helps with traction control and protects the engine from being lugged out in tall gears. High-performance operational modes are enabled and calibrated to deliver smooth daily driving, with a snappy and responsive throttle during moments of spirited driving. While retarding the timing a little can increase the exhaust gas temperature, we will also find that as we move away from MBT timing, the engine naturally will start to lose torque. What we are trying to achieve to spool the turbo is maximise exhaust mass flow as well as exhaust gas temperature. Boost control is set up independent of gear and turbo dynamics is used to account for the gear differences. The answer is that yes igniton timing can effect the way the turbo spools. Power is maximized in nearly all scenarios, eliminating the need for end-user adjustments. Boost will come earlier in the high gears and later in the lower gears. I see there are some from VividRacing, APR, COBB, Weistec, GIAC, and I am just looking to see what other people have gotten and why. With complete access to the thousands of maps, tables, and variables within, as well as a high-level understanding of how it works, APR’s Engineers were able to take advantage of everything the ECU has to offer. Looking for some advice on which ECU tune to get.

On the contrary, APR’s Engineers spent years mastering the ECU to unlock its full potential. However, what I realized was that the amount of time was roughly constant, but since it was making less power, it was at a loweer RPM when it got to max boost. To hear the exhaust cut a hole in the floor and route a small pipe from the exhaust into the passenger compartment behind the driver's seat. You can tune for 'faster spool' so that your datalogs look like its spooling at a lower RPM. The result is an incomplete product that often requires end user adjustment to maximize output in limited scenarios. To hear the turbo spool you need to drill a 1-3/8' hole in the topside of the compressor cover right before the outlet. Without mastery, the ECU must be simplified, removing what makes it so desirable. The ECU is powerful but extremely difficult to master.
