Hello Nick, Been a little while so thought I would see how your Vette is coming along. I am still recovering from the neck surgery. Not allowed to drive just yet. Hope to start physical therapy in January. Anyway have had the Vette on a battery maintainer. Went out two days ago, turned the key on twice to prime the system and the engine lit right off. Let it run up to temp then shut off. Now I have not done anything to it since October and a car show I went to. I downloaded the current global tune to see what is going on. I may make a couple of minor changes where I see that it could be smoothed out a little more. All the lower RPM tables are + or - .1-2 adjustments. Almost perfect. Could not be happier. Prior to the surgery I also changed out the accelerator to one from a 76. Reason, the 68 foot pedal is very large. I was having an issue getting WOT with carpet and floor mat in place. The 76 is perfect, plenty of room for getting everything from the TBI, and was a direct bolt in. I cleaned and lubed the entire assembly and it is silky smooth. (An flea bay buy). Almost to touchy. Also read where FITech got an outstanding review. I am glad once again we have several options to chose from and they all seem to be doing what they are advertised to do. Cost wise it is getting very affordable to EFI with the FITech, but still I am very happy with my Holley Terminator. Hope all is well. Wishing you and your family a very Merry Christmas and Happy New Year. The same to all our Corvette brothers and sisters.

 

Bob, glad to see the surgery went well. Physical therapy Always takes time, but better to take it slow then to force things..
So far the 74 never let me down, although I still have some tuning issues to address. There's a slight stumble when letting of the gas and immediately after accelerating again but it never dies on me. Another issue is static noise on the radio which I didn't have before with the HEI. Still have to look in to that as well. The motor is still a bit shakey at idle so I need to check my vacuum as well or turn up the idle speed a but (currently set at 750 rpm)
I'm not to comfortable with hooking up the laptop software. I think the instructions are not clear at all but would love to see the graphs and get a better idea on how my engine is running.
Last weekend I took it to a charity event for children with cancer in the rain (it didn't melt) and after a visual check I noticed both my throttle & TV cable nuts where completely loose (Lokar) so I probably need a TPS reset & IAC tuning. Maybe that's what causing the stumble/hesitation as I can't recall if I tightened them during install or I just forgot too.
Haven't pulled the plugs yet so no idea if they still foul or not.
Holley has a alternative for the Fitech : sniper. If it was available when we did the install I probably would have choosen the Sniper for a far more simple install but anyway.
Seasons greetings to you, your family & form as well and best of luck with the physiotherapy!
Nick

 

Hey Bob,
How's the revalidation going? By now you should be better then new no?
Any more miles under the belt?
i take mine out at every chance I get and so far the Terminator never failed me. Still some small issues to sort which is the stumble after coasting and big AFR swings. First thing I would like to do is install a 1/2" - 1" tapered or open spacer so the MAP sensor sees both banks as I'm running a dual plane intake and orther the throttle blade link. Blending the learn map with the fuel map and smoothening it did help
At least I have more confidence in the car then when I was running a self tuned carb and distributor..

Has anyone converted a C-3 Big Block yet? My concern it hood clearance. On a bblk you need to use the factory 2 inch drop-base air cleaner for clearance. It appears that this could be an issue because of the fuel inlet "plumbing" would prevent the drop base from clearing the unit. If anyone can shed some light on this that would be great. Also, does driveability and improve despite the Ethanol in the fuel today (to help I use Sta-Bil marine grade).

 

Hello Nick, Well I'm glad your Vette did not melt. Mine gets rain here in sometimes not so sunny Florida and does just fine. :-)

The terminator works perfect each and every time I drive the car. I have not put a lot of miles on it since November but even after sitting in the garage for what seems like an eternity it fires right up and goes to work. I was able to volunteer to work the Amelia Island Concurs De Elegance and drove the Vette there. It is about a 80 mile round trip. Well after sitting for nearly a month, it fired up no issue. Just for fun I decided not to let the engine get any temperature on it and started driving immediately. I am happy to report it performs flawlessly. I did have an issue with the old 1968 accelerator pedal. It continued to get in the way of floor mat and then sometimes the transmission tunnel. Basically could not get full throttle and it would stick. Well did a little research and the 1976 pedal is smaller but has all the same hardware. So got one complete off the bay and put it in. Way more smooth and almost had to relearn driving the car. So much better now.
Don't be shy about downloading and looking at the software. As long as you don't try to upload anything you can look and play all you want. Not much more to share right now. By the way you car looks great in the pictures.

Hey dan69bbk, I understand your concern. Really can't help much but to tell you that the Terminator is almost the same dimensions wise as a Holly 4 barrel. I would guess you will have to use your drop top base air cleaner. As for the fuel in/out, I could be wrong but you can use a 90 degree elbow (AN6) to get what you want. You may need to message the drop base in any event but not by much. Go to the web site and download the instructions for the Terminator. I think the dimensions are there as well. From a picture you can see the fuel crossover and in/out lines are really low. I think you will run into this issue no matter what system you decide. You may want to research some more on other threads and forums for information. As for drivability and mileage increase, read my other posts on this thread. Not saying you will get the same results but if these systems are set up correctly you will see marked improvements in all area's. The system does not store any fuel in the unit itself, like a fuel bowl or something so the only fuel you need to pay attention to is the fuel in the tank. I have not had any issues with fuel per say. I have been using fuel from a good known source however. Oh yes, it runs great on regular. Good hunting.

 

I've recently finished converting my big-block 69 to the Holley Terminator. Hood clearance isn't a problem. In fact it's about 1/4" shorter than the Holley SA 770 carb it replaced. My drop-base air cleaner cleared just as it did with the carb.

I'd really like to move to multi-port injection one day, but I'm not willing to switch to a hi-rise hood so I'm stuck with the pancake LS-6 intake (rectangular port heads). I don't see how the injectors and fuel rails would fit under there.










Ignore the wiring mess!

 

Hey Nick, still out there? Wish you a Merry Christmas and Happy New Year. Well it's been a while since I put anything on this post about the Terminator. I have no regrets at all. It continually performs better than my expectations. The quick start up and throttle response is great! No issues with it at all. I should probably do a little tuning but will need to get a little smarter first so I don't mess it up.
One thing that I will think on is the IAT (inlet air temp). I currently use an open filament air cleaner. I have read that this may create some issue because of all the engine heat etc being sucked in. It may not be anything at all but makes sense. I know the IAT does affect fuel delivery so will have to research it a little. I really don't know what to do to try and route air from the front or something. Here in Florida temps and humidity get very high. If the result is one or two miles to the gallon then may be really not anything to worry about.
One thing I will do in the future, get a different fuel tank. I need one that is baffled. My return line moves fuel around in the tank and therefore moves the sending unit float constantly. Almost impossible to get a good read on amount of fuel. This occurs when the tank has about 3/4 or less of fuel in it. Combine that with the normal movement of the car and, well you see what I mean. Been leaning towards the tank with an electric fuel pump. I think it comes from Tanks Inc. (http://www.tanksinc.com/index.cfm/pa...rod/prd443.htm)

Other than that, I am completely happy with the terminator. Hope that the other systems are working well for others. Anyone have any thoughts on the fuel tank issue? How about the IAT modification? Looking for some idea's. Thanks.
