BMW E9x N/A In-line 6 Valvetronic – Dyno Comparison (325i vs 328i vs 330i)

Here are the results from recent testing of 3 BMW E9x vehicles: 325i, 328i & 330i. All vehicles have no modifications to the engine and came in running CA91 premium pump gas. Each graph depicts the baseline (before tuning) vs. after ecu tuning runs. The engine configuration is the same in these vehicles with the exception of the 330i which has a different intake with variable geometry. Exhausts differ slightly also. From a tuning stand point these vehicles differ only slightly with the exception of key maps. Adjustments to the “valvetronic” tables make for safe and easy power gains from tuning. Each tune is a complete product with features like; top speed limiter removal, with improvement to throttle response and all round drivability. Each of these products is available for US$395.95 (from OE tuning dealers and ECU send in) or $595 with E-Z Flash (includes 4x map pack).

BMW E90 328i Dyno Tuning


Here are the results from a recently dyno tuned BMW E90 328i. The results are from the “off the shelf” flash (no custom dyno). Changes made to the valvetronic system, torque management, fueling, timing, throttle response and top speed limiter removal make for a completely developed ecu tune that was tested across many models and fuel grades (tunes are available to suit all octane levels). The gains on a Dyno Dynamics were: +14.8wHp@5200rpm & +19.4wTq@4100rpm (power to the wheels) running CA91 pump gas with no mods. This same engine is also used on E60 528i and 128i.

Each of these products is available for US$495.99 (from OE tuning dealers and ECU send in) or $695 with E-Z Flash (includes 4x map pack). More information on map switching and OBD2 flash loaders for BMW can be found here: http://oetuning.com/blog/?p=162
