+1 to the last reply. @TonySandberg, this thread is in the Feature Request section, about adding P&H injector control to Speeduino. Your question is more fitting and would likely get more replies in the User Projects or General section, as your posts are not about adding a feature, but about a 24.5% limitation issue when you try to run Speeduino on MS settings. These are two different and unrelated conversations. We are certainly not the "forum police", but other users that want to see you get good answers to your help request, by placing it in the most appropriate section. It also helps others find answers easier when they have the same or similar issues.
