ACES EFI Killshot Pt: 8 Cold Start Issues FIXED 

Awesome! I'm glad it was helpful. Good luck

No not me but I've heard of this from very few others. First off, is the system new? You have 1 year of warranty... so if you're coming up on that year mark contact their customer service right away! Half the time when that happens it seems to be that the ECU got fried. Next, when you turn the key to the run position you should get a red light on the left on steady, next to that a blank light that turns blue when engine is running only, next to that a red light that stays on steady for the main relay (check power lines or relay connection if not). Next to that a blue light that comes on temporarily that shows the fuel pump turns on to prime the engine then turns off unless the engine is running. If the 1st red light is not on or that 3rd red light is not on, you have a power/wiring issue (again check power lines and relay connections). I would make sure you hooked up the red and black leads to the battery and not the alternator (some have made that mistake and it can fry your ECU). Those red and black lines need to be wired directly to the battery and nowhere else. Make sure you didn’t hook up the VMain line to anything. Make sure your connectors are in tight on the relays, ECU and into the Killshot itself. Pull all those plugs out and make sure the electrical pins aren’t bent. Only other thing I can think of, is a wire in one of those plugs is not seated right. Sometimes the plug wires come lose. That is to say, they aren’t locked into the plug and when you push the plug in the wire pulls out the back slightly and doesn’t make contact. When the plugs are in, tug on all the wires individually slowly and check to see if one comes out the back. Seriously though you need to tell them you’re having this issue first for warranty. That’s a lot I know. I’m sorry you’re having this issue. Seriously, to me it sounds like a fried ECU or bad connection. Remember the ECU and system get its ground through the engine. I’m assuming your engine block has enough grounding straps to close the circuits. Good luck bro.

What's up bud? Do you need voice call? Text or email? Do you have Discord? Or you wanna chat in here?

@@dc10tech911 what ever is easiest for you. Having huge problems and actually in a dispute with Aces right now. This unit has never ran properly from day 1. Only reason I want to know how you would want to chat…is because it is a long list to even type lol. So let me know. I can send you my email, phone number. However you choose. I subscribed to your channel when i first got the unit, and have watched you since for hints. But i think im out of my league in the tech dept 🥸

@@kap400 do you mind starting off with the Discord app? You can install it in PC or phone. It allows us to message each other and make voice calls. If you install it search me out under darkragexx74 and send me a friend request. I'm leery about giving out my phone right away... especially on this open chat where everyone can see it.

@@dc10tech911 sure. Whatever makes you comfortable. Thanks ill set it up asap.

Hi I got a question did u ever encounter a connect timeout killshot may be offline message on handheld.. that was the first thing that came up when I turned key on..

Not sure what you mean. How to put the distributor to 15 degrees and how to change timing in the handheld? If you mean how to lock out the ACES distributor and then set it to 15 degrees and program timing curves I can't do that because I don't have an ACES distributor. I chose to use my normal vacuum controlled distributor instead of having the ECU control the timing. I've had people tell me I'm losing out, which I know they are right in a way... but then again my install works great and others don't... soooo. At the time it was because I couldn't afford the full top end kit, but lately I've been noticing that the people talking about having issues all seem to be having timing issues related to not getting the locked distributor right and that's causing all kinds of grief. Do you mean something else? I'd be happy to try to put something together, just let me know specifically what and I'll see if I can with the way mine is set up.

@@dc10tech911 I am also using my distributor and the time I have in my engine is a 8btc.i wanted to ask if I leave it at that or move it to 15 degrees? Like the manual says? I have seen all your videos and they have been great help to my system.

@@alexmeza5087 Ahhhhh. I understand now. Initial timing of 8 degrees is a little low. Is your engine stock or is it a mild build because that sounds like what the factory called out on an old stock engine. Either way, the Killshot is made to run with the initial timing set at 15 degrees in order to help the engine start easily. Set it to 15 degrees btc and hook up the vacuum line of the distributor to the small vacuum port (metered vacuum) at the rear passenger side of the Killshot (it's in one of my vids). The Killshot will start with that 15 degrees and then the distributor will handle the timing from there and the handheld will even show you how the timing is changing in one of the sensors on the screen. That should get you running like a champ. Do you still need a video on it? I can make one but it will take me about a week because I was about to leave town for 5 days to see my father in the hospital.

@@dc10tech911 I would thank you if you did one, thank you for responding and I hope your dad gets better even if I don’t personally know you. Best wishes for his health.
