Dave Clark Posted September 15, 2020 Report Share Posted September 15, 2020 Really odd but when I turn my ignition on it seems to trigger a backfire through the intake, and sometimes it's quite extreme (loud)......Doesn't do it al the time but fair to say it's at least 80% of the time.

Adamw Posted September 16, 2020 Report Share Posted September 16, 2020 Yeah we have a couple of guys reporting this now. I have asked engineering to take a look if there is something that can be done. Quote Link to comment Share on other sites More sharing options...

Simon Posted November 17, 2020 Report Share Posted November 17, 2020 Relatively confident we have a solution for this unfortunately it does require a hardware change, Units will need to come in to the nearest office for the work to be done. neo277 and Dave Clark 2 Quote Link to comment Share on other sites More sharing options...

Thanks for the update, I've sent a screen shot of this to the retailer I purchased from as we're currently on our 2nd ECU Quote Link to comment Share on other sites More sharing options...

Adamw Posted December 10, 2020 Report Share Posted December 10, 2020 13 minutes ago, Dave Clark said: RMA? The ECU needs returning for modification or replacement. RMA = Return Material Authorisation. We dont really have a true "RMA" process - but we do ask the customer to fill out a form before sending so when an ECU turns up we know who the ecu is from and what we have it for. Also as part of that we give them shipping instructions so they dont get stung with customs/tax. Quote Link to comment Share on other sites More sharing options...

neo277 Posted January 22, 2021 Report Share Posted January 22, 2021 Just an update I confirmed with tech support last week and they have the fix for the issue. I shipped my ecu back and they are doing the update and shipping it back. cheers Z Quote Link to comment Share on other sites More sharing options...
