#2 – TuningNoob
Thanks! Does this work on EDC17C49 without removing the ECU?
#3 – Dr.Obd_Tools (OP)
Yes, OBD works fine on EDC17C49 (tested on VW Golf 7). Just make sure your Kess/KTAG drivers are installed.
#4 – FlashMaster
Checksum correction fails on Simos 18.1 for me. Anyone else?
#5 – ECU_Solution
@FlashMaster – Use manual mode and select "Simos18_CRC_Fix_v2" from Tools menu. Works 100%. Davinci Software 1
#6 – Mercedes_Diesel
Can this do CRC for EDC17CP44 (OM651)?
#7 – Dr.Obd_Tools (OP)
Yes, but only via BDM. OBD write will brick if checksum mismatch.
#8 – VAG_Cracker
Link dead? MEGA says "bandwidth exceeded". Mirror?

Davinci 1.0.28 is relatively old. For 2024/2025 model vehicles (Bosch MG1, Siemens SIM267), this version will be useless. It only covers vehicles roughly from 2004 to 2017.
Instead of hunting for "DaVinci Software 1.0.28 UNLOCKED" on MHH AUTO Page 1, consider these legitimate alternatives that offer similar functionality for low cost:
| Software | Price Range | Best For | | :--- | :--- | :--- | | TunerPro | Free / $39 | Old school OBD1 and EDC15 maps. Manual checksum correction. | | ECM Titanium | $300/year | Great for diesel. Legal, cheap, frequent updates. | | WinOLS (Starter) | €500 | The industry gold standard. Pay once, own it. | | PCMFlash | Pay-per-token | Excellent for bench and OBD flashing with free file editor. |
