Hondata

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?

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 ...

My 2026 DE5 does the exact same thing after every upload. I end up having to use a different scanner that I keep handy to clear the DTCs. I get codes for the BCM, LKAS, push-to-start, and a few others. The car seems to run fine once they're cleared though. Have not tried waiting a few ignition cycles.
