I'll try to look harder...
anything about Fuel recurve?

I think this may help us get rid of that nasty jerk I hear about.

Semenos:
Those features are coming out in 1.20.. it should be released in two weeks.
xenocron:
You can already edit stock maps. :-/ Stock maps are contained in the PGMFI_ROM-NA.bin ROM. Those are the stock maps of a PM6.
If you need something for your B18A1, just import the stock PR4 maps.
If this doesn't fix your situation, I don't believe I understand what you mean by editing the stock correction maps?
As far as the jerk in OBD0 boost, it is being actively pursued.

I personnally believe that if we can find and tap into these maps (which Honda spent $$$ building & tuning), that will take care of problems such as the jerk. It wil also mean not putting in a different chip for Open Downpipe, Drastic Temp Changes, etc.
Is what Im saying clearer? I have a rough time with wordage sometimes...I think I tend to confuse myself occasionally.

I don't believe Honda's work quite that same way. Take the PM6 for example. There is only one set of maps. Yes, the PR4 has 3 ignition and 2 fuel, but so far, we have only found that the PR4 uses the first map of each section.
As far as "correction", the operation is done in closed loop. This section of operation is still foggy, and we're working on cracking that. Closed loop uses a few things including O2, *and* the static fuel and timing tables.
But, as far as I have looked into the actual source code for the current ROMs being used, there are only one set of tables. The static tables. :-/

Hmmm...you quite possibly are right...hell you know way more about all of this than me. I am just speculating of course.
Think of it like this though...you think Honda developed different maps for cars they were going to sell in Denver as opposed to Florida? Not bloody likely, besides closed loop only can correct up to 5% tolerances or something like that Ive heard...go beyond and that and I think it would throw a code or go completely into open loop, which is what it does at WOT, right? And closed loop is only for emissions, not for drivability reasons so there needs to be some other maps in there somewhere. (Again, all speculation)
I'd really like to be able to help you, Blundar and anyone else working on this "crack" of the honda ECU as you put it...however, i have no real coding or cracking talents. So if there is any way I could help, someone please let me know.

Re:www.TurboEDIT.org by TurboEF9 (Current version: 1.18)
Hrm, I hadn't heard about the 5% thing before.
How I understood closed loop in a Honda to work is that it gathers the O2 signal voltage, and with the static tables as a base, it calculates the pulse duration.
This would allow for correction in Denver and Flordia because the car would be using a different portion of the static maps based on the atmosphereic pressure. This value would greatly effect manifold pressure, thus "changing" the portion of the map for the elevation the vehicle is running..
This is just how I understood it to be.. this could be very wrong.
Can anyon confirm one way or another?

Re:www.TurboEDIT.org by TurboEF9 (Current version: 1.18)
What would happen at WOT in Florida vs. Denver when the ECU goes into Open Loop? The florida guy would be running much leaner most of the time. After years of that either the Denver guy would have issues of running rich (bad plugs, engine troubles, clogged CAT, bad O2) or the Florida guy would have durability issues from running leaner...is my guess.
I say 5% because I heard that somewhere and also on a Honda a narrow band O2 (which is what is reporting to the ECU correct?) is very limited in its accurate operating range. I would guess that the Honda ECU automatically goes into Open Loop when it knows that the ECU is out of its accuracy range. Although, why does a Honda automatically dump tons of fuel into the engine when an O2 sensor gets clogged and goes bad...hrm?
