It worked perfect. I needed to get a replacement ecu. It came in super fast. All I had to do was swap the existing and reload my settings. My truck fired up on the first try. Thanks again for all your help!

Yes everything worked out great! Thank you very much for everything!

The system is working great. Still trying to figure out the IAC revving issue but other than that its great when cruising.

The ECU is robust and easy to set up by utilizing the start up wizard. The ability to manipulate settings in the tables can be a challenge if you don't have a grasp on the parameters your working within. Read, research and learn a little.

I purchased a killshot 2 system second hand. it included the distibutor which i chose not to use. I was able to get everything fired up and running but 3 days later the ECU died. I bought a replacement ECU, performed the update and it works for now. Customer service is a joke, tech support is a joke.

Oh absolutely junk. About my feelings you in 2025 I believe it is now mid April 2026 in my truck if you’re not running because it is a user absolute garbage and getting a hold of somebody to sort it out is a nightmare right now. The guy is great. Absolutely the technician is great when you can get a hold of him But he’s by himself and And clearly the product speaks for self because she is so swamped there that like you can’t even answer emails or get a hold of youand clearly the product speaks for self because he is so swamped there that, but he can’t even answer emails or be able to tend to everybody. Because after I finally got a hold of him, no he went above and beyond to get me another one but this new one has the same problem and I’ve Got to not call in again and go thru the whole process again Which I have zero time to do like I am way behind time because it took almost 2 months just to get a hold of him the first time which was all the time I had because my truck is sitting on somebody which I have zero time to do like I am wavy on time because it took almost 2 months just to get a hold of them the first time which was all the time I had because my truck is sitting on somebody else’s property, and now that I’m done renovating it, I need to move my truck like a month ago in the time window that I had wss burned up just trying to get ahold of them the first time. So now I am way up a creek without a paddle, mileage for the gift for Robyn the best choice I’ve got it this point is to yank this whole system out and dig out a carburetor somewhere at my parents, and put it on and hope to **** that it’s dialed in enough which I don’tf foresee being so lucky. Oh, I would say is before buying go find the customer created Facebook groups becauseOh, I would say is before buying go find the customer created Facebook groups because there’s multiple of them. join them and just scroll/read all of the posts, everybody’s real life problems that they’re having. I mean this outfit is more worried about coming out with new products than They are getting already existing product working correctly. I mean the system is indeed an easy install but it Is the mode finicky and failure, prone thing I’ve ever come acrossso many things I’ll be little bitty tiny thing that can mess it up and either make it malfunction or apparently just feel all together I guess I don’t know.

Because we’re all stuck with them so far only option is to either trash or #MIN either lost or try our damnedest to figure out how to get the piecesBecause we’re all stuck with them so far only option is to either trash and eat the loss or try our damnedest to figure out how to get these things to work.

Took way too long for the warranty process, and then another month to get it replaced.
Almost 2.5 months to get 1 ecm replaced.

The first ECU failed before I even got the motor started. Then I could not get Ace to answer my e-mail or the tech guys to tell me what to do next. After 2 and a half weeks I finally got a new ecu. I went to another company and installed a ecu from them and it worked wonderfully. I will not be purchasing anything from ace again. I asked for a refund but they will not respond to my calls or send me a return label.

The wait time alone to get a replacement part was ridiculous. Trying to get a hold of anybody in customer service or tech support was ridiculous, I sat on the phone for hours waiting, had way too many emails not replied to. I figured a customer that has patience and temper control would see something offered back, like a new system to get things going since it was a HUGE ball drop on your guys side loosing my ECU. But there is nothing offered and I lost time and money due to this mistake. I'm not happy.

Buying this fuel system has been one of the dumbest things I’ve done. Should have spend the money on a Holley. Maybe they would have some customer service. Spend 4 months to diagnose and get a new ecu that I suspected the first day. 2 months to diagnose and finally get told to send my ecu in and then took another 2 months for them to check it once it was there. No one will respond to emails and every call is a minimum of 30 mins. Honestly if I have one more issue i will be taking it all off and sending it all back

good customer service

China trash

Havnt installed yet and probably wont for another 6months as im still gathering parts. But everything appears to be ofgood quality.

Everything works fine, but I’m on my fifth computer and still can’t get no VSS output and transmission will not shift out a first gear

Ecu will not turn on fuel pump, the wire does not give out any power at all. But the handheld display shows in the corner that the fuel pump is on. Also the firing order is correct in haldheld but is still giving out the wrong firing order.

There is a problem with this unit will contacting customer support.

Great service and product, had to replace ECM due to a body shop frying the first one. ACEs took care of me and new ecm firedthe engine right up.

Quick to take my money slow to respond when I have problems would not do it again

I used the Killshot with your fuel, ignition box, coil, and distributor. The product looked good and fit well. Setting up the software was mostly straightforward and easy to accomplish. Your web page is not up to date with the screen display, and that can be frustrating as well as lead to calling for help.

Great products and support.

been messing around with faulty parts for over a month now. Customer service is not helpful.

I had an issue and aces was easy to deal with and had me a new screen on the way pretty quickly.

Great service, very durable and quality products and excellent customer service couldn't ask for more outta a aftermarket supplier. Aces will always be my first thought if anyone asks me where to look or who to choose..

Great kit

It seems to have fixed the issue

Love it

Great deal thanks
