Powersquirt fuel and spark maps are free for public use. These are general maps for various engines that will get you up and driving around provided your PSI EMS is properly configured and wired up correctly. We assume no responsibility for those that use these. That means don't just load up one and start tearing down the track (or street) without caution. If you blow up your engine, its not our fault.

Everyone's engine is different; even with identical bolt-ons. These fuel and spark maps will provide you with a good starting point for your tuning attempts. More engines are being added all the time, so please keep checking back.

If you have a tune you would like to have us host, shoot us an e-mail at: tuning@powersquirt.com
