I'll tell you what, I'll take that fuggin POS junk Holley off your hands. I ain't gonna pay much for it though, since it's a giant turd.

I do run fast, but haxby can remote tune those as well. I called and left a message, but no return.
I understand, he is busy.

Running great in closed loop and "all over the place" in open loop GENERALLY means the basemap isn't optimized for your in-boat setup.
Vacuum leaks, sensor connections, fuel pressure stability - those also can trigger frustrating problems.

I've been running ms3pro's for a couple years now, they worked great at first but moisture killed them. I don't know if Holleys are as sensitive but it might be worth considering

The Holley is fully potted.

heres a couple of things, find someone who has made this stuff work..alex haxby, make sure your 02 is not getting ANY water back to it, I have been down both the roads and will drive you nuts

that's another issue is the o2 sensors, the clock is running on them. I've had them last a month, and a week. They hate salt water even worse. Get your tune locked down, then get into open loop.

I'm switching to Holley. is anyone here ( Haxby? ) a reseller for Holley? I need two dominators

I've been running the Holley system for over 4 years with no issues ....closed loop the entire time ... I do not "learn" below 1200 rpm ....we did kill a cpl of O2's at idle at first and then it would dump a bunch of fuel ...the fix for that day would be to go back to base tune in open loop ... I carry a spare O2 sensor but since the change at idle no issues for quite a while ....always carry my tablet with me just in case ... 540 M3's 850hp ....

Just a note we did have some issues on the Dyno .... I believe the dyno had some RF issues and since in the boat they are nonexistent ...........m

Same for me - 4 seasons now with Holley HP on stack injection unit. I only activate closed loop & learn above 1500rpm. Also carry a spare o2, but haven't had to change one since I ran across and started using this item (just a little more protection from water with no noticeable difference in AFR reading).
