Confessions from the BOE tuning tower🙂We’ve been busy enough that we haven’t been promoting our advancements in Evora 400 and 400+ (S2 Evoras) tuning ability very much. We understand the interest is high, and we are happy to tune them.
Data from the BOE tuning tower🙂 One of the largest changes in the S2 Evora is the torque management that is implemented. As we look at other tunes on the market for the S2 Evora, we can see there is very little understanding of how to tune the torque management in the ECU. It seems the others are only tinkering with spark, fuel, and maybe the cams. While there are small gains there, the big changes are in the torque management. Torque management in the calibration will work against efforts to make more power. This is why you see such minimal improvements in the S2 performance from other tune providers from just tuning alone. There’s actually a lot on the table without hardware changes—and all just in the torque management.
Below image is capturing a few pulls. Stock (brown) and then stock with ONLY our torque management tuning (green) and then stock with torque management and little extra from the more traditional tables (red).
Notice the HUGE torque improvement in the midrange. As the revs climb, the torque management in the stock tune falls to zero and that’s why the top end looks identical to stock (green vs brown line). The majority of the torque management in the stock tune is in the mid-range. Perhaps needless to say, but tuning the S2 Evora without control of the torque management is a fruitless endeavor, in our view....
In addition to torque management, we tune cold start/idle (seems to be terrible on both S1 and S2 evora), limp criteria, fans, idle, redline, fueling, cams, spark, amongst dozens of other tables. Also interesting, the IPS and manual cars have the same calibration from Lotus, but the calibrations are referenced completely different based on which trans is in the car... I wonder if others have figured out the differences. We’ve seen data that would indicate no😉
This is just one car on our dynojet. Dynos are dynos. There’s a lot that impacts the actual numbers displayed. Importantly, focus in on the difference from pull to pull. Same car, same dyno (our in-house dynojet).
