Following the example of a few members here I contacted Suzuki Australia to record my issue with the fueling from closed and also under 3k on constant throttle and see if I qualify for a replacement. I have reproduced the a portion of the correspondence below:
"I am writing to discuss a concern I have with GSX-S1000 I purchased through ******* in ***-2015. The issue relates to the inconsistent and on-off jerky nature of the fueling when opening the throttle from closed and when attempting to hold a constant throttle below 3000 rpm. **at this point I provide specific examples, not interesting****
I have read that this is a recorded issue on a number of sites and have read on GSX-S1000 forums that this is being raised with Suzuki national sites in both the UK and US as well as Australia. I am of the understanding that a replacement ECU is being provided to bikes that have evidence of the issues I detail above. As the issue is both safety and quality related I would like to investigate the options for my bike and put it forward for ECU replacement."
I receive the following email #1
"Thank you for your email, we suggest making contact with your authorised Suzuki dealer they will be able to advise if the machine is in the VIN range and then looked further into your concern.
So above indicates that the issue is recognised and specific to a particular number of bikes with certain VINs. I questioned why HQ could not provide the information as I did provide the VIN of my bike in the first email.
"Thank you once again for your email, the reason behind referring you back to the dealer is that we require them to carry out a diagnostic on your machine if the machine falls in the range of unit that are eligible to be assessed for the replacement ECU. We are more than happy to correspondence to be show to our dealer.
All right then, that's what is going to happen next. New tyres are going on on Saturday and hopefully they will check the ECU at the same time, I have yet to confirm. As this progresses I'll give an update or two.
I hope that this will be of some assistance to those considering a replacement as well.
