🔥 In Simos18, one of the key ignition control maps is the minimum ignition angle during Sport / AMAX gear shifts.

This map controls how much ignition timing the ECU is allowed to reduce during the shift event. The lower the ignition values are set, the more aggressive the behavior becomes.

With lower ignition targets during shifts, we typically see:

⚡ More overboost during gear changes
🌡️ Higher cylinder and exhaust gas temperatures
💥 Stronger exhaust energy and a more aggressive shift sensation
⏱️ Slower recovery of ignition timing back into positive values after the shift

This is one of the calibration areas that heavily affects the Sport / AMAX feeling and torque continuity between gears. However, excessive ignition re**rd can create unnecessary thermal stress and reduce overall efficiency if not calibrated correctly.

🎯 In our experience, excessively re**rded ignition during shifts is not always the fastest approach.
We usually recommend avoiding overly aggressive ignition re**rd in order to achieve more consistent performance, faster recovery, improved reliability, and better long-term efficiency.

Proper calibration is not just about making the shift feel aggressive — it is about balancing gearbox response, turbo behavior, combustion stability, and long-term reliability.

This applies to Simos18 ECUs.

When we tried to hit 3.2 bar aprox... we ran into an intake issue that came from a cracked throttle body after several abuses and pushing over and over for high boost levels.
So for now we pushed 3.15 bar when it cracked and started to leak, we manage to squeeze 814 hp.🤯

Keep following for the next session a free we will sort that hold 😎
