For those of us who enjoy tuning cars to get the most out of them. Standalones, reflashes and other tuning wizardry are all welcome.

All 4 rules of r/ECU_Tuning

Give us info
Reading the stickied guide to post is a must. 99% of ECUs in the same model and engine car will be different, give us as much info as you can
Cloned software talk is a no no
legal reasons, we don't want to close this subreddit because someone is too lazy to Google
No coal rolling or pops and bangs
The people who do that have been disaster for car enthusiasts. We want clean air and we have been already punished enough by laws just because 0.01% of car enthusiasts didn't receive enough attention when they were kids
No "low effort" cross posts
Cross posts are only acceptable if they are 100% relevant to this sub and contain adequate info for the users on here to provide help

What the written rules don't show

Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.

Let your AI read the rules before it posts.

ThreadFox reads a community's current rules, writes a post that fits them, posts once with Reddit's Brand affiliate tag and checks it stayed up. The free ThreadFox Lite reads rules too.
