Frank, I enjoyed watching the video. A quick comment...the low idle is a quick fix; check the IAC value, which should read 10-15% to ensure there's enough air for the engine to breathe at idle. You shouldn't have to connect it to a laptop to get the idle rpm adjusted, but a laptop certainly will give you much more latitude for fine-tuning....but the Holley Terminator X handheld should get you there. You're always welcome to call me with any tuning questions. And don't forget to hit the throttle good and hard in your next video so we hear it "bark". -- Jim Inglese
Thanks Jim glad you enjoyed the video. I have a tuner coming soon to look at the car and work out some if the issues. Thanks again for all your help on this. I'll talk to you soon.
Idle air control is over-compensating for the temperature. Definitely not a big deal. Judging purely by sound, idle target should be up around 850-900. That 600-650 won't cut it with the cam you have in the cold. The charge is too dense... especially for an ignition map that can't compensate.
Hay Frank it's Neil , stackers always have a problem with cold starts in the winter, it can make the difference of how it feeds the fuel to the engine. Chock system is different than stackers, as they can be tuned to cold weather. The temp has a lot to do with it. You are inside of the problem my friend. Thanks for telling me of what you told me many mouths ago. Take care Bro, Old Master Gunnery SGT USMC.
I was beginning to wonder where you were, Frankie. Now we know. That EFI stack setup is the bee's knees, brother. Super sexy! A thing of beauty and a joy to behold. I'm hoping to talk you into bringing the car into the school shop so my auto tech kids can drool over it. Two things on the starting/running issue... 1) The ECM does have an adaptive learning strategy so it will improve with run time. It will store data in the RAM as you drive it. Also, remember that learned data will be lost whenever you disconnect the battery. 2) Those 8 throttles are letting in 30-degree air and that air is not warm enough to help the incoming air vaporize the fuel coming out of the injectors very well. Keep us in the loop as things get tweaked. Congratulations, brother.
It's running sure lean. It does need to be driven but this is the wrong time of year for that. Hope a good tune will work out some of the issues. any of your students do mapping? digital tuning?
The tuning just needs to be finished, that's all. It isn't getting enough fuel during cranking, not enough after start, and not enough fuel in the fuel table for cold temp enrichment. With a little more tuning, it will run running perfectly.
The engine is probably too lean at idle or too rich depending on the air he needs...so you might have to do a little ECU tuning and calibration if the engine was tuned only for running into the dyno

Looks awesome Frankie! Cant wait to hear it in person! Oh, and I love how that A+ gas station was playing your videos on their TV! :)
Your the only one that noticed that..... the magic of editing . Lol
At around 8:15, Frank asks something like, "How does it look?" I said, "It looks cool" out loud. Well played, sir.
Thank you!!!!!!

I dont believe you pump the throttle before starting with EFI systems. They dont have accelerator pumps to richen the mix on startup.
You are correct, and I'm running super lean I'm adding more air to the mix and that's the reason I'm having issues at start up.

Thank you..... its all warm and in my garage now......starts much better
@@BanginGearsGarage Truly hope to see you in fall of OC. Love you my brother, Old Master Guns. USMC.
@@mastergunnerysgt1258 I'll be there as always, see you soon

@@BanginGearsGarage Unfortunately, mapping is beyond a high school auto tech program. I'm hoping you will be able to video the mapping process.
@@johnking8557 Me too.... it's kinda interesting. the Dyno might be another question. Too many dyno car explosion videos on youtube, LOL
@@BanginGearsGarage I teach at a college, part-time and they had a Mustang dyno but pulled it out because of the liability (mechanical and safety).
All planed for video, thought it was live!!
Nope, not planned. Thanks for watching.

Thank you Jim...... after turning I'll be making another video .
I want to put a 8 stack downdraft efi, on a 427 sbc, for a corvair im going to restore. It'll replicate a 60's 70's vintage racer.
Nice your gonna love it!!!
It’s jus cold start !
Needed to be electronic tuned. After that, runs amazing!!!
Man Frankie, that intake looks sweet, Hope the tune works.
Thank you.... its all tuned, runs like a champ. Need to make an update video
@@BanginGearsGarage can’t wait to hear it 🏋🏻♂️
Why are you pumping the throttle before you start an EFI??
I see some backfire through the throttle blades. Maybe running lean? The EFI system should automatically run it rich when it’s cold
Because I didn't know better and was so used to starting it the old way. But thr car has been tuned and running great.
@@BanginGearsGarage that’s great to hear
@@BanginGearsGarage lets see the new video.....
@@robertsamspon4232 Have you watched this short video after it was tuned? ruclips.net/video/w8z3OlS20wE/видео.html
The engine is probably too lean at idle or too rich depending on the air he needs...so you might have to do a little ECU tuning and calibration if the engine was tuned only for running into the dyno
It was rich, you working g it all out and it runs amazing now. Thank you for your comment!!!
Will get better, just let the holley system learn and will get much better
Yes, just the wrong time of year for that, lol. Might need to freeze my a$$ off or wait till spring.
Old car nut that I am and you know that I will always will tell you the truth.
I guess Mike didn't want to be seen on camera.......lol
He never does, always runs the other way.
Beautiful baby?hmmm well agree
Thank you
They don’t let me customize anything they just got info In their wedsite
You customize when you call Jim and talk to him.
