I kept adjusting timing, fuel tables, AE vs TPS, AFR target, etc. I even took it to a "professional tuner" and it came it running just as poorly as it did before.

I went thru three WBO2 sensors at $130 each. The last one went while I was on the track at Harris Hill Raceway, ending not only my track day, but the entire Texas Cobra Club meet that I wait all year for.

I think these are good systems, just finding the right tune seems happenstance. There is no stock 408 stroked Ford, 195 AFR heads, 2400 pound, manual transmission, 9 inch rear with 3.73 rear gears tune.

I ripped it all out and went back to a nice quick fuel carb from Blykins. If anyone wants to try a Holley Terminator system, I've got a slightly used one for sale.

Probably should have gone with a HP or Dominator system. Both work excellent on engines with a lot of mods and big cams.

The Terminator system is a HP if you connect a laptop. I gave up on the handheld after the first day.

That doesn't seem to be the way they are listed on the Holley website. It looks like the HP is a different line than the Terminator line.

Excellent?? I recall a thread on here where Vintage Motorsports our backdraft dealer ditched this system because it did not work. For everyone who says they love these self learners there are countless threads where 5 can't get them to work. One is the az cobra club on here stated he tried the fast ditched it because Bob Rhem efi expert could not get it to work with a big cam. He went back to a carb. It may work for some and not for others. Seems strange.

One thread on here titled. Breaking down efi options. Many complaints about the self learning systems. I can link the thread for some reason. A search easily finds it.

Funny, yet I visit a site that is dedicated to LS engines and they are running 1400 hp twin turbo E85 engines with 11:1 CR, massive cams, 7500 redline etc..etc..etc..and that is all they run. And they drive them on the street. Heck, my factory EFI handles a cam with 250 dur @ .05 and well over .600" lift and it will run with the MAF sensor and in closed loop. My cam isn't even that radical.

I wouldn't rely on the self tuning to run on a daily basis, but it seems to work decent to get the car fired and put on a few miles so you can fine tune it.

Maybe people just don't do their research enough or think they can get by with a cheap system. The Dominator is definitely not cheap and it has a large learning curve, but it will do whatever you want it to do.

The Holley self learning system won't support 1400hp. The Holley dominator is a multiport system. 2 totally different efi set ups. Lol

I will say this. The Holley terminator sniper self learning efi I believe it's called looks awesome. You really can't tell it apart from a Holley carb. Side by side they are identical. I saw one in polished finish and was it looked spot on.

I wasn't talking about a self learning system and neither was anybody else. You brought that up on your own. If you read the posts, nobody else is discussing it either. We are talking about EFI in general and making it run on an engine with a lot of modifications and how much time/work it takes to adjust and make it correct.

Reading comprehension is a plus! EFI systems work fine with huge cams and lots of mods if you spend the time to make it work correctly. Thousands of people are doing it daily.

Can you tell me what a Fitech efi system is. First post in this thread. Is it not a self learning system. Lol

Right here you said it. Reread your post. I did not bring it up on my own the op did. Yes I know about efi and as I stated I'm not a fan of the self learning systems. That's what the op asked about. Lay off the drugs. I'm sorry you can't read.

I have been using Big Stuff 3 (BS3) for the last few years. It works well, has good drivability, and makes really good power. My Turbocharged factory Five makes 924hp/ and 986wrtq on around 18 pounds of boost. BS3 also has great Data-Logging, when you plug up a laptop to the system. The car makes more power than you will ever need!!
