2026 DE5 Type S 93 Base Map

[blk.de5]

Hello all, I recently got the ECU on my 2026 De5 Type S jailbroken and had the Hondata 93 octane calibration uploaded. There isn't much info on specific figures for said calibration, and I'm also new to Hondata (coming from Ktuner in an 11th-gen Si). The car seems to be targeting 26-28psi at full throttle in 3rd gear and above, and it also seems to "stutter" at partial throttle in 4th gear every now and then. Boost seems to come in around 3500 - 3800 Rpms very aggressively as well (stock tune power curve felt very linear and manageable). I'll try to upload a datalog as soon as I'm able to as I'm very busy nowadays and barely have time to myself. I've already smoke tested the car from multiple different points in the vacuum/charge pipe layout so it doesn't seem to be a boost/vacuum leak. It also seems like the 2026 model-year DE5 has an issue with several DTCs showing up after every calibration upload. I've heard a few people mention that they go away after a few drive cycles, but I usually just end up clearing them with a different scanner as they don't seem to show up on my FlashPro Manager application. Any help/information is much appreciated.

Has the calibration been tuned for the intake? If not that is the problem.

The 27Won intake uses a stock sized MAF housing and the factory elbow for the vacuum distribution block. Either way, there's no way to select any specific intake when chosing the 93 octane calibration on flashpro manager for the DE5 type s. Youre telling me I need a custom tune?

It will need to be properly tuned to work with that intake.

Make and post a datalog and then people can look at the fuel trims. About 95% of intakes alter the AFM enough to require tuning; even those certified by CARB not to do so.
