- Still troubleshooting the ignition issue, but I got the USB cable that connects a laptop to the Holley sniper unit and now I can view what the engine is doing in real
Time while Making adjustments to the tune tables

No electric car can sound that sweet!
Screw electric vehicles....
Thanks ! It’s a super fun street car and I agree, no electric cars in my future !
nice nice.. sniper controlling timing too? you'll wanna transfer that learn to base soon. looks like its correcting a lot.. also looks hella lean at idle btw.. usually want idle a bit more on the rich side. 14.5'ish normally.. some of the bigger cam guys run 13.5-14. also, what's your timing look like at idle? looked like i saw around 20. can probably bump that to more around 25'ish.
Thanks for the comment. This was filmed a year ago and I’ve made very many tweaks to everything now. The car runs awesome and it’s also taking well to my nitrous system. I simply shot that video because I was happy the laptop cable and Live usb-link install went well. I’ve tuned everything much better since then. I have my target idle at 14.7 afr in most temps and map ranges. Dialed in my idle timing to 22 deg and my wide open throttle is 34.5 degrees. When I’m
Spraying nitrous I pull out 2deg for every 50 hp shot. Currently at a 150 Wet shot and I’m pulling 5.5 deg . I haven’t done a walk-around video like this in a while, perhaps I should
Make a new one. If you look at some of my other videos on this channel you will see/hear that the car is dialed in.
What's all the pointing about?
where does the laptop connect to?
I had just got the system running via the laptop and I was filming it for a friend and pointing to where he needed to look. It connects to the USB/Can-bus connector that comes out of the sniper ecu. You have to buy a splitter and then the length of cable.
Did you notice any delay in the read out on the laptop? I'm planning on using a windows tablet as my dash cluster
Not that I could tell actually. It seemed to jive with the handheld readings. It is wired via a splitter so the data should be arriving to each device at the same time, but if the computer/laptop has some type of lag to it, I couldn’t tell.
@@IROCZman15 Appreciate the quick response.
How did u even get the pc to see and connect to the pc in the first place
You need to buy a USB cable that can plug into a laptop. Since you probably also want to use the handheld too, you will need a cable splitter too. A good company to buy from is EFI solutions Pro. They have both the cable and the splitter
@@IROCZman15 i have the usb cable and the software. windows make a noise when i plug in the cable. but it wont sync/connect the pc to the sniper.
@@FatGuyBuilds there’s a button you have to press to “sync” send the devices together. Look for a usb sync button on your laptop. It will then display a new window showing its syncing status
There is a really good article on the tech resources section of the EFI systems Pro website too
@IROCZman15 that is grey'd out for me. Not clickable. Apparently i read that there is a usb driver i need to find and click the .exe
Here’s a video of me pointing at stuff
Yea, I was making this video for someone who was helping me get the tune dialed in and instead of me shouting over the engine, I pointed at what needed to be viewed and noticed. So what ?
Just came across this video. How does it connect? Just 1 wire to the little sniper controller? Do you have to download anything on the laptop? Would that work with a tablet?
You need to buy the extra can-bud cable and the Y-splitter for it to connect to a laptop. Cable can be bought on Holley’s website. It’s well worth the $
That’s a beautiful car, I have one close but not as clean as this! Anyway, do you use a battery disconnect switch? I do because I’m still building and don’t drive it much yet and when I leave it hooked up it seems to kill my battery so I shut it off. I think that I am losing my tune information when I do that, it seems I have to go back through and set it up again, I use the dongle as well when I am really checking it and is pretty helpful, although I am running the dual sync and Holley stuff, have you had anything like that? Thanks.
I do have a battery kill switch, mostly because I moved the battery to the back of the car and drag racing tracks require you to have a battery On/Off switch when you do this. However, I love having the on/off switch, because anytime I am going away from the car for a day or so, I just kill the power to it. Also for working on it and welding etc, I just hit the switch.
As for you loosing your tune info, that should not effect it. The tune is stored into the ECU of the sniper, and every time you use it, the tune adjusts and saves into the sniper ecu (which is in the throttle body). The SD memory card is used for storing tune files that are not currently in use, and it also saves any datalogs you create. Turing the battery power off wont effect your ecu's saved data or the data on the SD memory card though, so its likely you have another issue at hand...which I am not sure what it could be, I would advise ya to go over to the actual "holley efi sniper tech forums" and see if you can run a search for your issue, or create a post about the issue. Those guys are PROS and experts in this stuff.
@@IROCZman15 thanks for the information, one more question if you don't mind. By getting the splitter dongle you are able to make changes @ real time, then just save the file( on laptop) and it is automatic save in your handheld sd card? I appreciate the help, I am having some issues and really appreciate your time.
@@voodoowylde the dongle/splitter is a great tool. It does allow you to make detailed adjustments in real time and save them both to the laptop and to the sniper ecu. Then once the tune is in the ecu, you just simply save it from the ecu to the Sd card. The laptop does not link to the sd card while the car is running, but you can always put the file to the sd card afterwards
Is that factory red? Looks sicccck. I like the shaved shock mount towers. Did you weld them, grind them down and just use body filler?
Thanks man. Feel free to check out some of my other videos. I have a 15 minute one where I do a walk-around and discuss the highlights of the car. The red is a GM flame red. Code 81 C8508 A. It’s a DuPont Centari paint. I welded up everything under the hood but I didn’t weld the strut tower sheet metal actually. Everything else I welded closed and shaved
Dave Martin Thanks for the paint code. I’m not even close to that stage yet though haha. I have the 3.1 liter and getting ready to drop in a 388 with the sniper efi. I hammered the shock mounts so it sits flush so I can weld it but I burned through a couple holes(new to welding). I heard I can use a copper plate behind it, so I’m going to try that soon and grind everything down. Thanks for the paint code again, I’ll check out some of your other videos.
@@John-jr1si sounds good. yes, a bunch of people have welded the strut towers tot he engine bay sheetmetal. you have to make like 5 full passes, building the welds up on top of eachother. there are some photos on www.thirdgen.org. Often the filler cracks anyways though. To me, it just wasn't worth it, especially since I USE this car for drag racing, autocross, road course, and street use. You can use copper behind the metal to help weld closed the holes, the weld wont stick to it. I love the holley sniper efi. Glad i went with it.
Dave Martin How is long term reliability with the Sniper in your experience?
@@John-jr1si so far I have had great luck with it being reliable. I had an issue with it not liking the magnetic setup of my MSD ignition, so I switched over to the hyperapark which made the sniper even more user friendly. I use that laptop a bit but know I have more to learn. I am on the Holley EFI sniper web/forums where I have read a ton of peoples problems and tech stuff. That place is a wealth of knowledge
Where the cable goes on sniper efi for live tuning?
you need to buy a separate cable-splitter and a can-bus cable from holley or another reputable efi retailer and that is what can plug into a laptop for live timing. You will need the holley software on the laptop too
@@IROCZman15 thank you. I’ve ordered the cable from Holley and I’ve downloaded the software from Holley. Another question, if you don’t mind. Let’s say I change something in the injectors map through the laptop and upload to Sniper ECU, after that I plug the handheld. Will the AFR settings (idle, cruise and WOT) on Handheld would be disabled?
@@m.pietro9087 usually if you are seeing disabled handheld features it is because you used the laptop to created a detailed 3d style graph/file and the handheld can only adjust in 2d (very basic graphs) while running.
@@IROCZman15 thank you.
worst video it explains nothing and just pointing to stuff. Need to do a bit better
@@Don-uz9om no! This video was specifically made to SHOW this footage to ONE person and that’s all. This wasn’t any instructional for the masses.
@@IROCZman15 ah ok makes sense now. 👍
@@Don-uz9om yup. Sorry about that
In the early days of me learning efi, I needed some help so k shot this video and it was too big to send over to my buddy via text so I just dropped it here on RUclips for him to view .
If I had editing skills or better efi knowledge I’d make a tutorial but I’m not at that level
Ya know, if you talked and explained what you were doing it might make this video useful! Do you have a Mickey Mouse voice or something that your embarrassed about? lmfbo
Nope, what a weird comment from you.
I Didn’t make
This video for more than the two people to view actually . I had some people helping me get the tune dialed in during that time period and I filmed what it was doing. The video file was too big to send via text or email so I put it on RUclips. Is that a n acceptable answer to a jerk comment? Any other lame comments ?
@@IROCZman15 Yo, this wasn’t meant to be an asshole to you I was busting your ass! I was actually laughing watching the video with my buddy scratching our heads trying to get my sniper unit tuned! My buddy said “why won’t he talk? “ it was all in good fun! I got one of those lemon units from Holley that has been a problem from the start, and actually just got it back from them and it runs worse! Your video probably explains what I’m trying to figure out, but it really doesn’t explain it, lol, we paused it 46 times trying to keep up to what you were trying to show! Actually you would of gotten one hell of a laugh if you saw us watching it trying to use it to help us!
I could only see the first few words of your reply, I am guessing youtube moved/deleted it or something? Sorry, I thought you were digging on me. Anywys, all that aside.. I had filmed this video to share with the people who were helping me get lined out and it was just for display reasons, not any type of tutorial . sorry if it mislead anyone
