Tailored to perfection, this big turbo E85 ECU, finely tuned for the Audi A4 B6 with the 1.8T engine and 5 or 6 speed manual transmission, offers unparalleled performance for vehicles using ECUs 8E0909518AK, 8E0909518AF, 8E0909518AL, 8E0909518F, and ME7.5 wideband 1.8T variants. While the tune is a finished product for the B6 with specific hardware, specific adjustments—such as accommodating forged connecting rods, AWM thermostat conversions, or retaining a stock returnless fuel system, etc—can be tailor-made upon request before purchasing or conveyed through a message at the time of purchase.
Meticulously crafted for MAF-free operation, this 5120-hacked tune necessitates a Bosch 4bar pressure sensor: part #0281006059. The manual boost controller integration allows users to fine-tune boost levels up to 44psi. If you choose to use a MAF the tune requires an S4 MAF housing (73mm I.D.)
Ignition advance is finely calibrated, aligning with MBT for optimal torque and efficiency based on load, IAT, and lambda. Current settings cater to stock connecting rods when boost is >20psi for peak torque rpms, with the option to align more closely with dyno-tuned MBT values for setups featuring forged rods.
Exclusively designed for E50-E85 (flex fuel) use, the tune mandates genuine Bosch 980cc injectors (Part #0280158040). Tailored for a return-style fuel system from a B5 A4 or Passat 1.8T, complete with a 4bar regulator, although adjustments are available for those retaining the stock B6 returnless fuel system.
Any inquiries or clarifications can be sent in a message to this account. I\'m open to tuning other ME7 ecu\'s as well so just reach out.
