Took the boat out yesterday with the new Holley HP and new 72 lb. Injectors. Runs awesome !! This system very easy to install and use. Thank you for the Great customer service Alex Haxby.

My wiring is a lot neater than it appears in this picture. The pic was taken before I started plugging in my connectors

Did you use the static timing feature to sync up your timing? Im around today if you need any help.

Turn the frame rate down to 15 or 20, and set it for 30 seconds. It looks like you need to adjust the coolant temp enrichment so it will go into learn mode. What temp does your engine run at?

My Engine runs right around 100 degrees. I adjusted coolant enrichment down to 100 percent at engine temp 100 degrees. Even with that setting I was bouncing in and out of learn mode. So I adjusted to 100 percent at 80 degrees. Stays in learn all the time now.

To get really consistent shifting, especially with a big prop, it's best to tune the idle portion manually. I usually set the closed loop 200-300rpm above idle rpm.

Thanks to Alex's technical help line on a Sunday, I got my 540 running last night. Majority of the issues I had were caused by me and my wiring of the LSx coils but we got it worked out. The Holley system is beautifully easy to work on and make changes and I would consider myself an EFI novice and it runs great. If you are running a distributor, it is extremely simple then. Hoping to get it on the water in the next day or two and get some better video footage. Timing was easy to set and the software is very easy to navigate, it even gets my quite stout Bob Madera camshaft to idle nicely at 800. The components are all very nice quality and Alex's customer service is amazing.

This pic was before I had everything hooked up. Forgot to take a completed picture.

I just wanted to put in a few details about the outcome of my Holley EFI system pictured on post number 343. My system was bought from Alex haxby and built and installed by Mark Rinda at MER performance marine. I struggled for 4 or 5 seasons with a hard to tune MEFI3 system. The boat always ran very rich and never performed as it should or could. I have only had my boat out twice but I can honestly say there is a night and day difference with this Holley system installed. The boat runs awesome . Within 2 hours run time the boat is dialed in. I will post more details about it once I get it out a few more times. Jeff Wurl

It is a great unit, and has been very reliable in adverse conditions for many years. It is however, not very nice to look at... Everyone else was introducing new exciting looking throttle body's that, even if they didn't work as well, were outselling the Holley. So, Holley built a new unit based on the their throttle body that is used by NASCAR. It is much more aesthetically pleasing then the old unit, and so far seems to work as well or better. You can also plug a laptop into the terminator ecu to have full programability, and still use the hand held as an auxiliary gauge, for AFR, or whatever. The pricing isn't that much different between the two. If be happy to send you a quote for both if you like.

I was what you might call a beta tester for holley's tbi system back in the late 80's, when it worked it worked well, on the downside, the injectors were crap and I used to carry 2 extras in the glove box along with an extra controller. Learned a lot and caught a glimpse of the future of the aftermarket. Had Holley tech support on speed-dial. LOL.
