For some early vehicles, it is often the only solution. This upgrade is only available to existing users of the TunerCat software. The software supports real time tuning with the RoadRunner on supported vehicles, reading and flashing over the OBD2 port.
You must have a third party logger or scan-tool in order to have an effective tuning combination. Each VDF generally covers multiple vehicles that use similar engine controllers. Once you have purchased a VDF, you may tune as many vehicles of that type as you like — there is no per-VIN licensing. In fact, if you want the software to run properly we highly recommend that you use Windows XP as this is the only operating system that has consistent behavior without a fuss.

Supported Vehicles. V8 Cars. V6 Cars.If you decide to get into programming for yourself, there are a few questions you need to ask yourself.
First, you need to ask yourself if you are planning on keeping your current powertrain configuration. If you don't plan on making any other changes to your vehicle, it would probably be less expensive to let someone program your computer or chip. The obvious reason here is cost. Should you be one of those "hands-on" type of people, or your powertrain is constantly changing or being upgraded, then doing your own programming would probably be the least-expensive alternative. Below are a couple of links of good technical articles that explain the basics of tuning a vehicle computer as well as what special tools and equipment are required to do the job.
Most laptops running on battery power may not have enough internal power for the adapter. Or the power supply may be too noisy for stable communications. I have found this to be the case with some PCs or laptops which is why I use this design. There are quite few OBD-2 custom tuning software packages on the market, depending on what vehicle you have. Most of which can be found by a simple search on the internet.Whenever you modify anything to do with the fuel system, whether it is upgrading your fuel injectors, upgrading your fuel pump, or installing an aftermarket fuel pressure regulator, you may need to scale your injectors.
Before you get started, you should understand and have configured EvoScan for logging, have a way to measure your fuel pressure, and have a Wideband O2 sensor installed on your car. Without these tools, it is impossible to scale your injectors properly. If you do not have these tools, stop and get them before continuing or you will most likely destroy your vehicle.
If you do not, then following this guide will result in an improperly tuned car. For this reason, it's best to make fueling changes and intake changes at different times, and tune properly for each change after it is done.
It is possible to tune for MAF and injector scaling at the same time, but it greatly increases the complexity and difficulty of the task. When scaling injectors there are several core concepts that you should understand in order to fully grasp all of the variables involved. Understanding these concepts will help you to reason through the results you are getting as you change values in your ECU:. This is why it is so important to measure your fuel pressure when tuning injector scaling.
Fuel pressure affects everything. In my car, I have cc Injector Dynamics injectors with a flow rate of cc at my fuel pressure of This means that my rule-of-thumb injector scaling value would be:. Since the ECU will not accept that value directly, I use the closest acceptable value of It is important to note that this is just a starting value, and we will need to fine-tune it through logging fuel trims later. Do not simply place this value in your ECU and assume that it is correct. Fuel injector latency can not be calculated based on injector size.
This value is determined by other design parameters of the injector and can vary from brand to brand. The absolute best way to properly tune your latency compensation table is to get the proper values from the injector manufacture themselves.
Injector Dynamics is particularly good at providing this information, and you can find the proper scaling values for any of their injectors right on their website. If you have this information, make sure that you record your fuel pressure as the injector latency changes significantly with fuel pressure as well typically, injectors take longer to open at higher fuel pressures.
Once you have these values, you can enter them into your ECU. You can adjust both columns of the table both battery voltage, and ms to match the values you got from your manufacturer. The ECU will only accept values that increment by 0. For example, for my Injector Dynamics cc injectors You will notice that the highest 18v and lowest 6v values are not from the Injector Dynamics website.
You can safely estimate these values based on the curve of the others. If your car is operating at 18v or 6v being slightly off on your fuel trims will most likely be the least of your concerns. Unless of course you have also modified your electrical to operate at higher voltage. If you've done that, you're probably building a dedicated race car and I have no idea why you're reading this tutorial. The injector pulsewidth adder will need to be adjusted based on the flow rate of your current injectors at current fuel pressure vs.
You can do this by calculating a multiplier and applying it to all of the values on the right hand side of the table do not adjust the coolant temperature side. Using the example of my ID injectors with a flowrate of cc Again, these calculations are just a rule of thumb, and you may need to fine tune them. I highly suggest that you carry around a laptop for a while in your car so that you can log and if necessary reflash. It sucks to be stuck with a car that won't start while hot or cold because these values are not correct.
It's important you do this before you start the next step.Posted: 7 days ago TunerPro is a free, donate-if-you-like-it tuning platform aimed at making tuning easier and cheaper for the hobbyist and professional alike.

Due to a generous donation that got me another test ECM, EEHack development continues with a fresh test bench, socketed up ready to go and communicating with the cheapest FTDI device china has to offer which is really all you need to tune an LT1, you know.
Thank you to Mogielski and all the other supporters that have kept me motivated to keep working on this platform over the years even without having an LT1. I plan on separating the flash tool from EEHack entirely and making a better one that will support other ECMs as well.
Wanted: Dead, dying, or spare LT1 ecms for eehack development. Please email me address in EEHack credits if you have anything laying around…. Looks like the version of my old aldl-io console aldl program for linux was broken. The analyzer in 4. Thanks to all that reported it.
I really want to get it out there so I can start working on more dramatic features for the next version, and also prove that EEHack development is not dead. Another new beta version of EEHack. Also rewrote some old code related to log playback that could cause crashing in some circumstances.
As a bonus, playback speed is now variable. Another quick update, this one makes the graphing work properly again, makes the UI look a bit nicer missed a library in the last release. Thanks to Mitch for the quick testing. Please let me know how it works for you! Includes source. Combine the launcher and datalog window as the primary window, I always liked it better that way Major UI overhaul to fix scaling and performance issues with dashboard and other modules.
Use more dynamic layouts in most areas. I get a lot of comments posted directly to this site asking for support for EEHack.

Older posts.You can easily change the tune of your own LT1! For the average computer user and car enthusiast, there isn't much to it!
With an initial financial investment and some time set-aside, you can get your car running great and take advantage of your mods. I have some basics and tips I've picked up as I've tuned my own Camaro Z Much of it can be applied to other vehicles as well. This will be tailored to the LT1 engine, especially the ''95; the VE table tuning aspects will be even more helpful to ''93 and ''97 LT1s.
Second, you'll need the appropriate cable connector to go from your car to a computer. Of course, you'll also need a computer to run the program! However, it does not have definition file for OBDII cars ''02so you will only be able to tune ''95s. It's important to be sure that your vehicle and engine are mechanically sound before you begin tuning. If any of these things are in poor repair, they can cause the PCM to think the engine is running one way when it is not.
A good tune will never be achieved if something mechanical is in need of fixing or replacing. The PCM uses a table of cells to modify both spark timing and fueling.
Where the different blocks begin and end can also be modified, with the stock tune having the vacuum blocks set at 30 32 for A4s50 and 80kPa, and the RPM blocks set at for A4sand Combining these, one can see how there will be 16 total blocks: below 30kpa, at RPM, and RPM; then the same for 30 to 50, from 50 to 80, and from 80 to kPa.
There is another modifier for both the engine load and speed boundaries called hysteresis. This affects how adjacent blocks of cells are combined when on the edge of a boundary say right at 30kPa at RPM. These grids are how the fueling is trimmed, depending on O2 sensor feedback seen in detail below under "BLMs"so how they are set can be important to getting a car running efficiently, whether you are running a MAF sensor or in speed density off the VE tables.
When modifying the engine, especially with cams with more valve overlap, increased displacement, or ported heads, these will need to be adjusted accordingly. The modded engine will tend to spend more time in different ranges than the stock engine. BLM stands for "block learn multiplier.
Introduction to Injector Scaling
But because the car is not running in an ideal world, there will be correction needed for differences in air temperature, density, humidity, as well as fuel octane, quality. On top of those two big variables, there are also the changes that happen due to normal wear and tear on the engine and its sensors. By default, in closed loop, it attempts to get an air:fuel ratio AFR of LT1Edit was written by one of the first researchers into the EE platform. This is a dedicated editor written for one platform only, and is not extensible.
It provides a built-in flash utility. It has the LEAST amount of parameters available of any EE tuning solution, due to being fairly out of date and being geared towards the beginner. Tunercat is a package designed to edit bins for a wide variety of platforms, including the LT1. It is extensible and capable. The maintainer of tunercat is a very capable bin hacker, and has discovered many of the parameters now known to the LT1 tuning community. Tunerpro is a software package designed for the DIY bin hacker.
It does one thing, edits bin files, and it does it very well. Well, I have worked very hard to make a definition file that works well with tunerpro, and here it is. It is heavily documented with comments, and all of the parameters are categorized. You can grab the latest version here. Assuming you do not already own LT1Edit or Tunercat, there are two standalone options:. My own software. From the maker of tunerpro, Winflash is another excellent standalone flash utility.
Using Tunercat, some parameters that I discuss may not be available, or will be named differently.
