Codebase settings or bad wiring.
Who put it together?

Not everyone lives on the forum you posting twice within 10 minutes of each other isn't going to fix your problem. You should be trying to fix it instead of posting over and over. You'll get help in due time. I already told you the codebase output settings could be wrong. Verify them with what DIYautotune uses.


If you followed the FAQ exactly you shouldn't be having problems. If this doesn't work post pictures of your board with the mods completed. Did you jumper the three positions for the tach input?

If it's lean add fuel, if it's rich take it away. 100%= no extra enrichment. It should be running smooth if it's rich. Lean will make it oscillate. If you're only running on 2 cylinders then it will run rough of course as well.

Pay careful attention man, this isnt a toy. Stop rushing as well, because I get a hint that you are and this is definitely not something you want to rush.
