Tuning guide for ea888 is12, is20 & is38 platform

We have done extensive research and development on the VAG EA888 engine over the past 10 years, on all 3 turbo variants found across the the entire VAG range in form of IS12, IS20 & IS38. Our inhouse development has allowed us to produce some of the market leading calibration across all software variants commonly found on this platform. Both the 1.8 TSI & 2.0 TSI newer generations of engines are the successor of the EA113. Housing a completely different strategy of tuning now moving on from the simple BOSCH MED9 control unit to the more complex Siemens Simos18.

Here we show a great example of stage 1 & 2 taking place on a very healthy example of the EA888 TSI IS38 variant engine. This was an excellent example of an Audi S3 8v FL brought to us from stock and covering over various hardware and tuning stages. The graph defines what we have achieved within stages 1 & 2.


Stock:

310BHP & 289Ftlb (391NM)


Stage 1 Calibration:

367BHP & 370Ftlb (501NM)


Stage 2 Calibration:

424BHP & 402Ftlb (545NM)

Please note we have run stage 1 & 2 calibrations on these engines on stock clutch with zero slip. Please use your own discretion on the condition of your clutch prior to tuning. A stock clutch in healthy condition will be fine for both stages of tuning but will eventually need replacing for stage 2 calibrations depending on your driving style.
