OK since there are a few guys here that are trying to go a little deeper than just install, I figure I will post some of what I do... And don't use these files for your motor!!! you don't know what I'm playing with!!! Keep in mind this is not a tuning site!!! But I will provide all the basics you need to get just about any engine up and running with EFI. I discuss most of what "NEEDS" to be adjusted but not everything that "CAN" be adjusted and played with. OVERVIEW Tunerpro has 2 parts to it. 1 part allows you to change the settings in the bin(tune). It requires a file(xdf) that contains the parameters for the specific PCM you are using. The bad part is that those individual files are assembled/hacked from the factory bins by tuning enthusiast and not professionals. The files may contain errors that can have ill effects on your tuning process. This part of Tunerpro performs the same functions as Tunercat described in the FAQs. The good part is that Tunnerpro is shareware so it is free to download and only asked for a donation if you like it. Tunercat is free to download and use for 30 days with the tuning file for the 1227747 $42 ECM. (the one we use most on here) The second part of Tunerpro is the data logging. It also requires a separate file(adx) to interpret the data stream from the ECM into usable data. All of the data is flowing all the time, it's the individual adx files that determine which data you see. These files are also written by enthusiast. The data logging is actually separate from the tuning but open within the same screen. This part of Tunerpro function like Winaldl shown in the FAQs. Real Time (RT) tuning/emulating. This function allows you to tune as you drive with the correct hardware attached. Both Tunerpro and Tunercat have versions of their software available to do this. The most common hardware used is provided by Moates.net such as the APU-1 or Ostrich. Programming/Burning chips. This function is actually reading or burning the bin file to and from the chip. It requires hardware and software like the Moates.net APU-1 or Burn 1 or the GQ-4X Programmer shown in the FAQs. They all come with their own software to perform the functions and have a specific list of chips they are capable of programming. The Moates.net programmers can read the chip(2732) from the 1227747 ECM but can not program them. See the FAQs for details or alternatives. The GQ-4X can read and burn the 2732 chips. Neither Tunerpro or Tunercat can perform the programming function. Tunerpro can access the Moates.net software from a button on it's tool bar but it simply opens the Moates flash and burn software. Before you start you need to make sure the fuel pressures are right. Inlet is about 12psi and does not change even under full throttle. Return should be 0. Next, if you didn't follow the basics and pick a system as close to your engine size as possible then you may need to adjust the BPW-base pulse width. This calculation is used as the base number for all the other fuel calculations in the program. I have attached the speadsheet below. It will allow you to calc the output of your injectors at different fuel pressures and will give you a new BPW based on your input. To me they seem to run a little high when compared to GM's factory BPW. This new number is input in the constants of the bin file. Then: When you log data you want to save the BLM table by clicking save at the end of your drive and you want to click the data logger button and set it up by checking all boxes except the raw box. You should click start logging before you start the engine and stop logging after you turn it off. First you start with a bin file from a motor combination close to yours. Same as picking the right parts, 350 for 345/305 for 304/I use the 350 for the 392. I normally start with the ASDU file. You will then need the cable to log your data from your ECM while you drive. I use winaldl and the 1 transistor cable. See bottom of page OR You can now buy a direct USB cable from me for $30. See the machine shop forum under Hamilton fuel injection. It plugs directly into your usb port and connects directly to the ALDL connector on the harness. No adapter needed. The ALDL cable does not include the ALDL connector. That will be mounted where ever you chose. I just keep mine in the glove box. All you do is use a couple 1/8 spade terminals or simply tin the ends of the wire and put the ground in "A" and the serial data line in "E" The diagram shows the pin numbers from the back where you connect the wires. This pic shows the DB9 serial connector with the numbers on the front face of it, just in case you get confused. Here is what the BLM data looks like. Everything above 128 is lean, everything below is rich based on 14.7:1 AFR (stoick)!! NOTE: ALDLTOBIN is an optional program for making VE table corrections. IF you use it, it should only be used once or twice to rough the table in and then manual adjustments should be made from that point on. If the tables are within 10% if 128 BLM then the program should not be used. So I take the new logged BLM data(blm.txt) and input it into the "ALDLTOBIN" program(file attached below)...with the bin file(4-24.bin) I am using. I tell it what ecm I am using(1227747) and finally what correction tables I want to use. (W) If you have ever logged BLM data then looked at the data under word or excel you would see all the wide and narrow blm tables. Then at the end of the list is the narrow and wide correction tables. These are what the program uses to calculate the new changes. It's all pretty straight forward math that I used to do 1 cell at a time to make corrections...well you can guess how long that took!!!! : mad : So this little program will take your FL1+FL2 add them together then apply the correction for you. And it writes me a new bin with the fuel table changes made. I then open the new bin in either tunercat or tunerpro to edit the bin files. Both work and can be used for free.The graphs are a little better on the tunercat so I will show those here. (EDIT: the latest version of tuner pro now has color Graphs!!!) Here is the new modified fuel table. Note the peaks and valleys...This is mild compared to most. Here it is after I do my own manual smoothing. I try not to have any uneven gaps or spaces between cells. That can lead to a lean spot on accelleration or a dead spot on driving. You need to remember that not every cell on the logging gets data so they are not all changed. You need to log as much as possible under all conditions, highway, city, WOT, and you can't just sample the data once and call it good. There would be no avg. I try to log a min of 30 min drive time, and even that is iffy. But that is how long my drive to work is!!! The winaldl program will keep the data if you get to work just save the BLM table(just in case) then carry the laptop in to work and plug it in till it's time to go home. Then hook the cable back up and drive home. It will keep adding data until you close the program. This is just for the BLM tables. I don't really recommend you do the actual data logging option at the top of the program that way. The file will get pretty big especially if you save RAW data!! When you smooth your table, look at what you are changing. If you were really rich and the aldltobin lowered a lot of cells, you would see some large up spikes on the table. If you moved the data up to match those, you would be right back where you started from!!! If you change anything...air filter, injectors, plugs, timing...then you should recheck your fuel tables. The ECM compensates for small changes so you don't have to burn a new chip each time, but it will let you know where your at with your tune. Some other basics to tuning to keep in mind when using an auto adjust program like ALDLTOBIN. 1. The TBI goes into PE mode in the upper map areas. When it logs data there, it is either just returning to closed loop or just going out of closed loop. The data is probably already lean since ideal is about 12-12.5:1AFR. But the Narrow band O2 will see it as rich.(richer then 14.7:1) So when a program starts leaning out the upper columns..it's normally too lean. You will see this best with a wideband O2. 2. As mentioned earlier, the cells tend to overlap. If the cells are 400 and 600 at 30 map then the 400 cell is actuall 300-500 and the 600 is 500 to 700. So this is a main reason I manually smooth after each adjustment to keep the table from producing peaks and valleys. 3. The system is designed to adjust for varying conditions. This means that it can tolerate up to about 10% deviation without a problem. You should not and do not need to chase a cell around to get it perfect at 128. 1° temp change will change the cell. So if you log data at night then make corrections and drive it in the morning. the table will look off some. That's whay a lot of data logging is needed to get a good avg. the 30min runs will get you in the ball park!! 4. Once you have the fuel done....then comes timing. which will also affect the fuel!!!! Bottom line...don't waste time trying to perfect the fuel table. understand the basic requirements and tune it to that. Then work the timing. When done, come back and make a final fuel correction. _____________________________________________________________________________________________________________ CHIP BURNING I used to use a USTR.net programmer to burn chips it works well but requires a parallel printer port on your computer, But now I use the MCUMall GQ-4x. It's a usb programmer that can do the old 2732 eproms and the newer 27sf512 EEPROMs listed below. and the Romulator to do realtime driving and tuning.(not required) I also have to erase my chips each time before I program them, with a UV eraser. ---------------------------------------------------------------------------------------------------------------------------------------------------- For a second option for DIY programming that I think is better if you are just starting out, is to go to www.Moates.net and get the socket adapter for the EEPROM and the burn one. Then you can reprogram your chips without the need of an eraser. Plus you only need the one chip!! What's In My Cart? Remove Product(s) Qty.
