FiTech was hands down the best investment I made for my Pontiac. Awesome video and congrats on the first drive!

[@FastMonty]

Thanks Shane! If feel the same way.

[@AMGmeg]

Look forward to all your upgrade videos. If you keep the current arrangement rubber isolated the pump to reduce the pump noise, make sure to ground the pump. The in tank pump is simpler, eliminates all the extra hoses in the trunk. Safer, since you do not have fuel hoses in the trunk (passenger compartment) eliminating the possibility of something in the trunk damaging a fuel hose. Quieter, because the gas tank is enclosed and isolated. You have a great build going with really nice video series documentations. Thanks for taking the effort for everyone, inherited a fully restored 68 GTO convertible 4 speed from my brother who was the second owner since 1972. Have lots of plans for upgrades and improvements for the GTO. Keep up the good work.

[@FastMonty]

Thanks Brother! Yeah, I'm definitely leaning towards an in tank pump... I guess that'll be another video. :) Congrats on your 68... it'll be fun! See ya!

Yup, it'll work fine where it is... but, I'll be searching for something quieter. Will add to my "to-do" list, for sure.

[@Wickhaven1]

I put the Fitech 600 Power adder on my 78 TA and couldn’t be happier! I also put on a turbo, and the Fitech has made it so easy..I had duel inline Fitech 255lph pumps which worked, but sounded like I ran over a riding mower! We are putting in the tank/pump combo 58118 with a 440lph this winter, so bye bye under car noise!

[@FastMonty]

Nice Mike! Great to hear it worked as seamless as mine... I too yanked my loud ass pump. Have you seen my latest pump install? It took some work, but it is dead silent, and it's the production pump for Gen 5 Camaro's... check it out... it also has NO return line. kzbin.info/www/bejne/n6SZkpWLqdeJiKs Keep at it!

[@kimosabbe50]

Congratulations! When you said how nice it is not to have to feather the accelerator at stoplights I could totally relate ... with a few old school rides I'd owned in the past (I'm old, so they weren't "old school" at the time😬) And oh, that Holley fuel pump sounded like a mini jackhammer 😳

[@FastMonty]

Ha! Yeah that pump's gotta go... need to research some options, and of course, post a video about it some day. Thanks for the comment!

Awesome results, that's what I was looking for!!!! But I can get most all of that, while more difficulty, with a carb properly set up, hmmm!

Wow ,l honestly thought that their we're going to be some hiccups and adjustments right on the first test drive. I am speech less and happy for you that there were no problems and nice bonus to have FiTech offer to tune it to be dialed in . Freaking great video Mike as always but this has to be extra special for you . Take her for another spin for me.😂👍✌

[@hoost3056]

You can get a carb to do the same thing, it just takes more hands on work to do it. The compensation to altitude changes with EFI is what I like.

[@FastMonty]

Agreed, it takes some serious expertise to get a carb to perform the same, especially during cold starts. (I no longer have to feather the throttle to keep it running when cold, which is HUGE with Aluminum heads) No muss, no fuss, starts every time. :)

I feel your pain... you'll get there. Welcome to the FMG family... ask questions, as much as you can... ha, ha...

[@AB-80X]

You never told us what what you did to adjust the IAC properly. You just said the fans interfered. So is the solution to adjust the IAC without the fans on at a low temp or should the fans be on without kicking on and off?

[@FastMonty]

Sorry about that... Since filming this, I found that the engine temp should be above 135. The fans kicking on don't have much of an affect as first thought, but I do keep the air filter on while setting the IAC. Hope that helps!

[@briansmith3426]

Watching this series has me convinced I'm going with a new fuel tank with an in tank fuel pump and dual lines, this seems way more leak prone and complicated then it needs to be, plus that fuel pump sound level is atrocious, I just can't get on board with so many fuel lines running all around the car, especially in the trunk, by the time you realized something leaked it would be a huge mess...thank you for sharing and documenting it without bias 👍

[@FastMonty]

Thanks Brian! Yeah, that pump is obnoxious. I think Holley makes an in tank returnless pump... I'll have to do some research on that, and make another video for my Plan B fuel supply :) I appreciate the comment. Thanks!

Hey my brother I finally got it fix where I can cut my truck off with the key

[@FastMonty]

Awesome! What was the issue?

[@thedobermangang3503]

the problem was originally my fuel pump cuts on when i turn my key and cuts off so with that being said...the orange fuel pump wire coming from the fitech i did not need it..i disconnected it ..thats why my truck would not shut off ..everything is fine now ....i had to figure that out by my self ..the fitech technician didnt no shit..wast of time calling them and have to wait on the phone..

[@FastMonty]

yeah, I hear you... almost everyone has different wiring scenario's. I couldn't imagine being a FiTech customer support person, for that reason. I'm glad you figured it out, and thanks for leaving us a story to learn from. See ya!@@thedobermangang3503

[@dbohann66]

To clarify, do you need to set the iac before it reaches operating temp??

[@FastMonty]

It's just good practice because some systems will kick on electric fans when the engine reaches operating temperature. That will sometimes cause a voltage spike, affecting the IAC "learning" reading. Hope that helps!

[@dbohann66]

@FastMonty yes it helps. I new you had issues setting iac because fan was kicking on. So was curious what you actually done to set iac and get it stable.

[@FastMonty]

good to hear... I now also keep the air filter on too... keeping it as "real life" during the adjustment. Have fun! @@dbohann66

[@thinds8810]

When you set this up did you hook up a vacuum to the throttle body or the fuel cell regulator...couldnt tell

[@FastMonty]

The Vacuum? You mean the PCV line? I have a provision in my manifold for that, just below the Throttle Body/Carb flange. If you don't have the manifold connection, then you use the 3/8" tube on the bottom of the throttle body. Hope that helps!

[@thinds8810]

@@FastMonty not the sorce but where does it go...ton top of the go fuel because you were using it as the regulator or the on on the side of the efi unit its self...because in my head you have to provide it vacuum to work..

[@FastMonty]

@@thinds8810 Hmmm, still not sure what you're asking... but, there's a ton of vacuum supplied by the manifold that the throttle body, or carb is bolted onto. So, that in itself is sucking a massive amount of air through the Throttle body, or carb. Fuel pressure then sprays fuel into the air stream. Make sense?

[@justinsharratt7282]

So glad you happy with your efi. I too am happy with mine. Side note IAC is idle air control which I'm sure you figured out lol. Yeah you were chasing unicorns because of your fans kicking on causing your alt to draw more amps. same thing happens on AC cars when the clutch kicks in makes the motor work a little harder at idle so the computer adjusts how open the throttle is to maintain idle rpms. Still love ya brother and keep up the fun times.

[@stevesmedsrud4116]

With the amount of "jury rigging" going on with classic car rest/mod etc. someone wouldn't have devised a rubber mount gadget to keep those clicky clacky pumps off the hard body/frames. Body vibration + the solenoids operation = noise.

[@FastMonty]

[@stevesmedsrud4116]

I’m new to the “hobby” as I’ve heard it called regarding me. I was given a 71 c10 basic 350ci and power glide trans from my mother who was going into hospice care and needed to reduce her “holdings” so government couldn’t seize them. It has a edelbrock x4 but today carburetors are going out like the power in California. Do you find the efi system beneficial for the money?

[@FastMonty]

@@stevesmedsrud4116 Sorry to hear about your Mom... understood about Medicare rules. Anyway, welcome to the hobby. Yes, Fuel Injection is the way to go. No more head aches with cold starts, hot starts, idling around town, Wide open throttle passes, etc... always comes down to idle. :) Anyway, I'm still learning too and will be implementing Electronic Timing control, which is a built in feature of the FiTech system. (That way I can set the timing digitally, versus dicking with distributor weights, and adjustable vacuum advance stuff... yet another benefit of Fuel Injection conversion that I haven't utilized yet) Again, sorry to hear about your Mom, sounds like she has great taste in cars... :)

Hey Mike, you probably covered this and I need to go back and watch the series, but why didn't you use an in tank fuel pump. I Installed a Holley sniper on my 69 GTO (looks similiar to yours, except my dad ordered green interior) and other then the initial prime, you don't hear it at all. Car sounds great.

[@FastMonty]

Great question Michael... At the time, I was under the impression an in tank pump required a new baffled tank. Hence, more money. BUT, since filming my procedure, I came across the Sniper in tank (return less) pump... which looks awesome. I will definitely be considering it for my "Plan B" fuel supply. And of course, will film that install too... :) Thanks for sharing, and congrats on your build!

[@warrenstephenson3809]

Excellent video, I have a question I also have GTO (66) it has non original engine (Chevy 454 substantially modified approx 600+++HP ). After having my mechanic (experienced in fitech) fit and set-up the Fitech system. I've massive over fuelling issues during the install and test stage dumping fuel fouling the plugs and fuel going thought-out the engine and into the oil sump. The cars got both good quality MSD dizzy and coil systems. The car does NOT have a MSD Ignition Box fitted, do you or anyone feel I'm losing spark hence not burning the fuel and the system still feeding the fuel, would fitting the MSD box help with this issue. Or any other issues my mechanic might be missing. Any feedback would be greatly appreciated, Cheer's Warren (Australia)

[@FastMonty]

Great question, Warren! I've never heard of that issue before. Just thinking out loud... what's the fuel pressure? Does the engine start fine? Does it take forever to start? Like it's flooding? ... if mine doesn't start when cold after three attempts, it will have received three prime shots. (You can hear it "squirt" when you key on) On my fourth attempt, I will hold the pedal down during key on. (Holding the pedal down tells the cpu to NOT do the prime shot) Otherwise, you'll flood it. If the engine runs, I would look into how to pull the data, and study the results. @fitechefi Has some great videos on how to do that. Remember, it's a computer, if it's over fueling, something is telling it to do so. Which means something is wrong in the loop, like there's an exhaust like near the O2 sensor, and it's adding fuel to make up for it, etc. Obviously, I'd also send a note to FiTech for some guidance too. Let me know what you find!

[@frankiegee101]

cool video, very informative. My issue I'm having with my fi-tech is that the butterflies are getting stuck in the closed position and i really have to hit that pedal to get them to unstick.(which is bad if i have some traffic around me) Any info regarding that would be helpful. Thanks!!

[@FastMonty]

Frankie, thanks for the comment... yeah, that's not good. So, I just looked at mine... it's not on the car, which makes it easy. My valves do not fully close. I suspect that might be the issue. Have you called FiTech yet? I'd be happy to send you a picture, or short video to show you mine. Just send me an email.

[@frankiegee101]

@@FastMonty Thanks for the reply, i'm going to have to try to set that IAC more and hopefully open up the butterflies a bit. surprisingly, fi-tech is the one that told me to adjust the IAC by turning the adjustment screws (both front and back) all the way counter clockwise until it clicks, then turn them a quarter turn clockwise. That I believe is when i started having issues.

[@FastMonty]

@@frankiegee101 yeah, I'd back those screws out and start over. Not sure I'd touch the rear one, when you adjust it again. (My front and rear butterflys are connected, so I could see how they'd bind up if you adjusted the front and rear at the same time.) Let me know how it goes

[@frankiegee101]

@@FastMonty well, when i start from the beginning(screws all the way counter clockwise) my IAC steps is around 160ish. I've adjusted the front screw (clockwise) a lot. about half ways in. I felt a click and then more air started rushing into the throttle body. so i backed it off until the air noise stopped. So.....my current IAC steps now is 58. if i continue to screw the front one in more, the idle jumps up and i can hear more air going in. I will tell you though, my butterflies don't feel stuck closed anymore now that i've adjusted the front screw in a lot.

[@FastMonty]

@@frankiegee101 Glad to hear the blades aren't sticking anymore. If you're still concerned about getting that IAC below 10, I would remove the throttle body and reset the blade position on your workbench. Upside down, my blades have the identical angle. I see they're connected by a threaded rod, which is also an adjustment point. Which is why I don't see how the rear screw helps...

welp gotta say not impressed with the results. i went back and compared this to your first start and test drive after the engine rebuild video, and essentially, you spent all this money, all this time, all this work......because the carburetor you had on the GTO previously had no choke!! the start up with the carb was just as fast (if not faster) and even smoother than with the carburetor (at least in the first drive video) your complaint that it idled at 1800 with your foot on it until it warmed up is simply because the carburetor has no choke the acceleration right out of the driveway was smoother with the efi ill give you that. but the driving and the startup (which is the whole reason people rave about this EFI garbage) was no faster, and i could see no improvements unless there are some dyno numbers where you gained significant power gains with the EFI, in my opinion, the money and labor and time was not worth it for the EFI conversion
