Compatibility

ECU Hondash scanner Hondash app Remarks
Honda - Stock (OEM '92-'01) Compatibility guidelines for stock ECU
Honda - Chipped (Crome) Compatibility guidelines for Crome
Honda - Chipped (HTS, eCtune, BMTune)
  • Must use an internally installed Bluetooth module (for more details visit www.hondatuningsuite.com) to establish communication with Hondash app because the modified code running on the ECU does not support data transmission via diagnostic connector, therefore you can not use the Hondash scanner to establish communication. Honda diagnostic connector (3 pin) uses only one wire for data transmission (RX & TX - half duplex mode - serial communication), however the developers of eCtune (HTS, BMTune) decided to not support it and opted for two wire data transmission method (RX | TX - full duplex mode - parallel communication), requiring a 4 pin connector which does not exist, thus this communication method is achievable only via installing a Bluetooth module internally, bypassing the diagnostic connector entirely
  • Because the ECU does not support half duplex communication method, any attempt to use Hondash scanner results in ECU's buffer overflow causing the ECU to reset itself (Hondash app displays warning “ECU is not responding” and the engine idle keeps stalling periodically). Fixing this problem may be possible by HTS/eCtune/BMTune developers by making the half duplex communication at 9600 BAUD an optional method for data transmission as it was originally implemented by Honda.
  • Honda - Chipped (Neptune)
    Hondata In development (ETA Q3 2022)
  • Must use Hondata versions that come equipped with an internal Bluetooth module such as S300 (V3, V4) and Kpro (V3, V4) to establish communication with the Hondash app. (Hondata V1, V2 do not have a Bluetooth module)
  • OBD1 diagnostic connector is not supported by Hondata thus it’s not possible to use the Hondash scanner.
