Looks good Andy What type of sensors and trigger wheels do you use to generate the signal? Something you made or off the shelf MSD or Holley. I would like to do something like this with a knock sensor for when I get some crap fuel when I'm out in the middle of nowhere. I heard some detonation the other day when couldn't get fuel at my usual pump. Gus

What do you expect to gain in power?
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Here are pictures of the cam and crank sensors.

Are you planning to tune by cylinder- timing and mixture. It would be interesting to see if there is extra power to be had or if the result is just a smoother running engine Yes we'll tune by cylinder if needed. We have tuned fuel by cylinder with the EFI but now we can do ignition timing also. I don't have any experience with this so it will be a learning curve.

Nice !!!!! Looks very expensive$$$$$$$$$$$$ Well if you look at the total cost picture it isn't too bad when compared to what a carb + ignition + data logger costs. The Holley EFI system will replace the carb + the ignition box + coil + data logger. For a race guy those things are pretty expensive. A tuner 4500 carb can be $2000, the MSD 7AL + big coil is about $1000 and a data logger can be several thousand. So if you buy a complete Holley EFI system with coil packs for $5000 then it is about a wash. With the Holley EFI system you get things like start retard, high speed retard, high speed lean out, two step, power adder control, etc. for free. All you have to do is program the spark and fuel tables to do those things. If you are a carb and ignition guy then you have to go to MSD and buy add on parts.

Here is an interesting video showing 8 02 sensors. Megasquirt 3 can adjust cylinder trim per cylinder if you give it the data from 8 02s. Look how crazy the trim is until everything starts working together. I can't remember how much power they said this was worth but on an engine masters entry any power is worth it, I want to say it was 10-12HP under the curve. https://youtu.be/6kQGp-fHuFc

CNP parts for Mopars are now available from FAST Man EFI. Go to the CNP page on the fastmanefi.com site for all the details and pricing.
I also have available a custom pigtail for the Holley HP and Dominator systems that connects the 36X crank trigger and the cam sensor directly into the Holley harness.
