Thing is that the previous owner had done this with the previous set up, 02 sensor in etc, custom mapping- but had detonation and or sticking ring issues that I want to be sure to avoid. The existing program should be close, then I can take readings and ship the ecu to Mark or Dustin for tweaking in different ranges.
Brad has one of the better reputations around here and I will likely use his services, though he can't reprogram. He does use an egt sensor for each sesor so we can tune for the leanest cylinder. Ron in Tulsa is highly regarded but his dyno/abilities are not doing EFI right now.

Re: 540 in the werx!
Today is Dyno day 
Brad ran break in last night and today we see where the A/F mapping is. Will likely have to send the ECU out for tweaking, looks like Dustin will do it, Mark is covered up.
For those who slapped me silly in this thread and elsewhere- thank you. The small delay and investment is worth it in peace of mind for quality time on the lake and resale should I ever face that day (used to lust for twins but not as much lately).

Re: 540 in the werx!
Cattitude , have fun on the dyno , it's the best way to get her set up right . Let us all know how you make out , give us some dyno results . I had Jo rig my dash with boost and pyro gauges even though I have a carbed 540 now I will be ready for a whipple or maybe rtech , I can't wait to see what your new motor will do in the boat . Got to go mid to high 80's right ? When will you splash?

Nothing worse than having to do a rebuild job than to have to do it a second time. Keep us posted.
My exact thoughts. Dyno is not just for numbers

Re: 540 in the werx!
Mapping was so far off/lean we could not run much past idle. Sent ECU to AS&M, ECU should be back this AM, should be Dyno'd today- will advise
I've been a way the last two weekend sso did not miss any boating- plan to splash Sat.
