Default Turboedit tutorial(pgmfi guys, TurboEF9?)

is there anybody who would please share thier infinite wisdom and enlighten total n00bs like me about how to use turboedit by writing a tutorial? i have been interested in turboedit for quite a while, but i am completely clueless as to how to use the software. i understand the hardware side of the issue(chipping ecu, etc), and ecu chipping is in the FAQ's. unfortunately, i have been hard pressed to find useful literature on operating turboedit. i have been to pgmfi quite a few times seeking knowledge, but it seems that i am more confused when i leave than before i went there looking for answers. after starting the turboedit program and opening a bin file(like the stable.bin), i am completely clueless as far as what i need to do. what i need to know is how to manipulate the numbers found in the tables(vacuum ignition, vacuum fuel, boost ignition, boost fuel). i am assuming that the numbers found in the horizontal and vertical colums are rpm and pressure(not sure about the units), that seems obvious. rpms and pressure are simple concepts to grasp by themselves. what i do not understand is the relationship between the two. for example, on vacuum ignition...if we look at the relation between 500(rpms?) and -22(mmhg?), we find that 16.20 is the number produced. what unit does this number/relationship represent. another example, say boost fuel map... at 500 and 1.8, we find the number 6.73. once again, i do not understand what 6.73 is measuring, nor do i understand what i need to do to alter that number for my own personal tuning. basically, there are four tables(2vacuum, 2 boost), governed by two colums(rpm, pressure). what i need to understand is how to manipulate the numbers in these tables and columns. once i figure out how to do this, i can begin taking on all four of the entire tables and tune them for my specific tuning needs. in addition, any other information about how to use the editing features found in turboedit would be wonderful. an example of this is the "edit region" option found in the tools menu. how do you use scale, add subtract, replace with... and what do they do? one thing that i believe i have figured out is the ignition retard feature, since when you click tools-> boost retard, there is an explanation. you just highlight the areas on the ignition map that you want retarded, then enter a value for ignition retard.

please excuse the long post, but i just thought that a tutorial would be helpful to myself as well as many others. in addition, it would be great to put the tutorial into the engine management forum as a sticky. if i am asking too much, please excuse me. but, i believe that if more people weren't "afraid" of the program and understood how to use turboedit... and it wasn't "a bunch of technical stuff that only pgmfi guys understand," more people would take an interest in this wonderful program and perhaps add some helpful insight or at least have a larger amount of beta testers.

I'm also lost on this subject, a tutorial would help greatly.

I've been waiting for one of these posts. I think a step-by-step would be fantastic, although I don't think Jason has the time to do such a thing so if somebody else has the know-how to take this task on it would be greatly appreciated. I'm sure thousands of people have looked at the software and got so lost in it that they automaticaly discarded the idea of a free tuning program.

First off, you are thinking too hard...but i can understand your confusion.

There are two components, there is the software (the Editor - TurboEdit) and the ROM (the program where code, fuel and timing maps reside). Think of it like Microsoft Word. You have a text file, you can open it in Notepad or Microsoft Word...Word is a better EDITOR while notepad could do the same it just doesnt have the same easy features to use. The Text file is the ROM in this case.

When it comes to changing values, you really need to understand what is happening inside of an internal combustion engine to make changes to the fuel and timing maps. They are called "maps" because you need to think of them like a regular map. You have an X and a Y coordinate, Latitude & Longitude...if you know both, you know where in the map you need to be. Now instead of Lat and Long, think Vac/Boost and RPMs. Your engine is always sucking in Air or getting air blown into it(Vac/boost) and the Speed of the engine is obviously important. The honda computer uses a Speed Density calculation to figure out how long to fire an injector. Speed = RPM Density = MAP sensor and a few other sensor calculations to figure out the density of the AIR. The ECU says to itself..."I see 12 molecules of air...how much fuel do i need to add to make the engine fire correctly?" In boost you might want a 12.0:1 ratio, so in that case it would need 1 molecule of fuel to satisfy that ratio. A wide band oxygen sensor measures the exhaust gases oxygen % and lets you know if the values in the TurboEdit tables based on the two values (MAP sensor reading and Injector pulse width (how long the injector stays open)) were correct.

So basically, without dataloggin...you look at your Vac/boost guage while you are driving and it is displaying 10 InHg (inches of mercury) and at the same time you look at your Tachometer and it says 2600 RPMS you know where in TurboEdit you need to change things. Looking at your Wideband O2 sensor display at the same time it says 10.6 AFR...and you know that you need to change the value to shoot less fuel at that point to bring the AFRs up to the 13-15 range.

Basically, you really need to understand Tuning...then you need to learn how TurboEdit interfaces with the program (the ROM), and some of the calculations the ECU is doing...then as you work with the two you begin to understand how those two peices interact with your engine.

Once you really understand Tuning with TurboEdit, you really should be able to adapt that to any tuning software like Chrome or Uberdata or Hondata or ZDYNE.

Good luck...hope my simplistic approach helps someone and doesnt confuse any more than they already are. :P

Good explanation but I have a question about te2.0 and the datalogger, I got it running and everything seems fine but what exactly am I datalogging?

You are datalogging the stock honda sensors, RPM, MAP, IAT, TPS, Coolant Temp. and probably a few others...

I know these but what are the ones in the actual boxes in the rpm vs. map sensor area?

If you are talking about the values you can change in TE...with the fuel maps, the numbers represent injector pulsewidth (in milliseconds) and with the ignition maps, the values represent ignition advance (in degrees)

That is how I felt
TurboEdit is only for Obd0 cars right? Are they going to come out with an Obd1 Edit?

I don't think he wants to venture into OBD1, although he has mentioned it is possible if you know what you are doing.
