The limit is set at 7300 soft limit with a 7450 hard limit. When it reaches 7300 it cuts every other cylinder. At 7450 everything is cut. A 150rpm split seems to work the best.
It is programmable and you can set it anywhere you wish.

By the way this is a forum where people want to know and have some feed back specialy on performance parts, so I have to let them know that macs ecu blow up my ski and when I called him to let him know about the problem he did nothing about it. that's a very good information for people that have it so they can do something before is to late, like adding fuel pressure regulator, boost gauge, A/F gauge, and check for blow by if they have being using this kit for a while, is my dutty to inform every one that owns one so they don't blow up their ski like mine did.

An engine can run lean for a lot of reasons (many of which were mentioned) one of them being the ECU. You kept mentioning DETONATION - yet your pics did not show that.
Have you properly diagnosed why you think your motor ran lean? That is, did your esteemed mechanics check the injectors, look for intake leaks, or look for a blockage in the fuel system - prior to pointing the finger at the ECU?
Most importantly - did you show the links/pics I provided pointing to oil starvation/lack of lubricity to your mechanics? You'll notice that the pics of the pistons look EXACTLY like the pics you provided.
PS: When you get your engine rebuilt, I suggest that you let someone else break it in properly, use factory Honda oil for the first 50 hours or so, do compression checks/leakdown checks periodically, and look at your spark plugs after every outing (especially if you don't clean the injectors and flush entire fuel system)
