  • Technical Support on Powertrain Issues / KTM Duke 390

    Posted by Farhan Shahriar on September 26, 2023 at 8:10 pm

    Hello! As a first-year team to fabricate the car, we are looking for support.

    A few months back, we acquired a KTM Duke 390 from India, and initially, it operated seamlessly right after our purchase. We even went ahead and replaced the battery, which kept it running smoothly for a considerable period. However, in recent times, when we’ve tried to start the engine, we’ve encountered a persistent issue – the initial spark doesn’t seem to ignite. Unfortunately, we lack access to KTM Duke 390 technicians in our country who could offer us guidance and assistance.

    Hence, we kindly request your insights on how to resolve this perplexing problem. Additionally, we have a few more queries related to our KTM Duke 390:

    1. Could you provide guidance on the process of connecting the stock ECU to a laptop?

    2. We’re curious about which specific wiring components might need to be extended and, if possible, the procedure for carrying out.

    3. We’re considering whether it’s advisable to purchase an aftermarket dashboard or if a do-it-yourself (DIY) approach is feasible and, if so, the steps involved.

    4. Lastly, we’ve purchased a shutdown switch and would greatly appreciate your assistance in connecting it to the stock harness effectively.

    Your expertise and guidance on these matters would be immensely valuable to us. Thank you in advance for your support.

    We are requesting for some supports here.

    Hello Farhan, apologies for the delayed response, such issue of KTM technically should be solved from authorized KTM service centers. Due to student made intake manifold, KTM engine can cause multiple issues.

    Initial weak spark- weak battery could be the reason. Try switching to a new battery or externally recharge the existing battery and then try.

    ECU – not accessible as KTM doesn’t let user to access maps and mess with them. Authorized service centers have a special software tool to do so. Even KTM people don’t change things they only monitor parameters. One option can be to use piggyback ECU but it’s a tricky affair.

    Also stock Bosch ECU doesn’t connect to the laptop. They have their specific OBD tools to diagnose issues. Also the screen flashes error codes by which one can know what is going on with the ECU.

    Dashboard – is upto your choice, whether you want DIY or go for aftermarket one.

    Kill switch – You can series a shutdown button with that key switch or even can replace key switch with kill switch.
