FiTech EFI Install
#71
All,

Replaced my valve cover gaskets Saturday. Installed Vacuum Smoker and, Dang it! The stupid intake is leaking again. I had replaced the intake gasket not long ago. Back to the re-installation process. You Tube, he we go!

Found a good You Tube on aluminum head to aluminum intakes install.

so the FiTech is all installed. but I'm having trouble getting to start up easy and run correctly. I have to open the throttle after it fires and rev it a little to get it to stay running and idle. what settings did you play with that helped the most? I've already raised and lowered the cold cranking adjustment and it didn't help much.

In this guide check the section about idle in Page 4, http://fitechefi.com/fitech-uploads/2016...inalV5.pdf
I think that once you adjust the "idle" screw it would work well. Ignore the whole stuff about timing in that document. Then make sure you follow the instructions to set IACs: http://fitechefi.com/tech-posts/fitech-e...tructions/

All,

Here is the issue with my intake leak thus, likely causing my erratic up and down behavior during run time.

I replaced the intake gasket by locating the gasket to the intake ports and holding in place with RTV. I let the RTV dry and the installed.

This maybe my Bone head award of the year!

that would do it lol I took mine out for the maiden voyage and stopped at its new part time home and took a pic lol gas hungry for sure!!! but it is driving really nice so far. but it doesn't have the low end tq outer used to with the carburetor. hopefully it just needs time to adjust and since tuning.

Casperfast,

Nice! Did you install the EFI 600 version?  Please check out https://www.fitechefituning.com/ . I have account there to research the FiTech EFI.

All,

After all of the hard work with the vacuum leak of the intake, got it sealed up and running. I still had the gas smell, and smoking from the exhaust side of things. I also noticed , after shut off, that a fuel vapor was coming from the top of my FiTech 400. I said, never seen that. I finally said, what the hay, let's see if the AFR is adjustable on the EFI400. Sure enough, it is. I adjusted from 14.7 to 12.1 and wow, what a difference it made. Another "Bone Head Moment here! It is the best I have the EFI 400 running on my roller 302! Now, off to the IAC and tweaking the AFR settings.

Thanks,

All,

I was able to resolve the fluctuating RPM issue with my FiTech 400. It was a modified CDI box from Intellitronix. The signal from the CDI must have been erratic or dirty, thus causing the fluctuating RPM problem. Also, my factory tachometer is now working. I was looking into the modified tach from Rocketman. I may still do it to prevent possible issues with a bad tach. This CDI might be designed for carburetor engines. I plan on emailing them to see.
