Thanks for the help guys, all makes sense now!! And sorry for hijacking your post Mike.

 

That really stinks that your dealership wont flash for 4/1 or 6/2 flash. They have the ability to do it but choose not to.

 

Do you know something I don't? My setup is 6/2 and I have full fade ability with no LL and it sounds good. If there is something I am unaware of, please let me know as I don't want to give bad advice.

 

 

Yes sir. All direct connect and no rca to worry about loose connections, vibrating loose or bad grounds.

 

I do know that the flash thing is highly subjective and that this fine gentleman has the BT 355s Focal Amp, and a local shop that will only flash the 0/4 setup. Very proven results that are simple. Time = money in various cases.

If dudes that have 0/4 flashes w BT355s start chasing the various other flashes thinking its the holy grail they will in general be let down as most of these various strategies are lateral moves. Of course there are custom shops that use proprietary flashes that fit their very specific builds. And corporations like RF uses a specific flash for their specific products, kits and wiring harnesses as do ARC and various others.

Furthermore the MOCO really has locked down their tech computers regarding flashes and Indy shops with flash capability are few and far between. Path of least resistance and plug and play from HD HU to amp = BT355 and 0/4 flash.

If dudes still think they want to attempt the imho lateral flash via an Indy then I would only advise them to not make the same mistakes I did. Save every penny u have and don't waste a dime on flashes and put that cash towards a fund that will purchase a DSP or an aftermarket HU. If u want to go next level the truly go there with a DSP or HU thus save the flash experiment cash for objective advances, not the subjective ones. Having a 6 or more band EQ added to the Boom is an objective advance. Then sell ur BT355s to the next brothers that come along to recoup the HU or DSP expenditure.

You are absolutely right about the 4/0 flash with a bt355 being a proven setup. I did that also but got to thinking that with that setup, the original signal is being filtered twice if you are using a hp filter on your amp. Now I may be wrong in my thinking but filtering the signal twice looses SQ and more power is needed to over compensate that twice filtered signal. After reading RF post on flashing the boom hu so not to need a LL I found an indy thru RF website that can flash it. I went there, talked to the guy, watched him flash my hu, trying both 4/1 and 6/2 flashes and we both agreed that the 6/2 flash was better so we left it at that. He showed me the tool and program used. It was a standard techno research diagnostic tool that is the same diagnostic tool the HD dealers use to see code, tune engines after stage 1/2 fuel packs are installed on sled. It is the same tool HD uses to flash their hu's. There is no proprietary program RF uses nor proprietary HD program for these flashes. I do also know that now my setup is crazy loud and my gains on the amp are around 10/11 oclock where they were at 1/2 before. I have no drastic signal curve, no bass distortion just crazy loud good SQ tunes and a direct non filtered signal from my hu. $85 for a LL that filters the signal vs. $70 for a flash that doesn't have a filter in place and reduced gains...I choose to save a buck.

Call me crazy for thinking outside of the box, but I am looking into buying this tool use in future setups to provide a better setup for boom hu's. Hell I am even trying 5x7's in the fairing to see if they will give a better SQ and more bass than a 6.5 and as of right now, the set I have in there are working well but that's another story.
