Turbo Tuning / Re: map interactions: cause and effect

« on: November 20, 2013, 12:13:02 PM »

Working on the side, the next version will not have this feature, the WAR chip is not designed for this type of work. I am using an ostrich emulator you were thinking of buying in your other thread on bfc.

It's most likely not your plugs. Anything between .018-.025 is safe under boost from misfires and good for every day use. If the car idles rough you would want to make the gap wider, closer to the .025 mark.

Yes P/T fuel and P/T ignition is what you want to adjust, the key here is to keep everything as smooth as possible rather than making it choppy, simply try changing the values by small amounts.

The problem you are having with the tabs is a known WAR software issue that is being address in the new version, the new version is going to be released soon. Until then click on the tab you want to save to, open the map and write it to the chip when ready. The tabs always stay the same as does the TCM.

Neither the DME or the diagnostic tools are aware of the WAR chip replacing the original EPROM, therefore I will have a hard time trying to narrow this problem down for you. It might have something to do with using a DME from a different car? Again its hard to say. If you are simply trying to retrieve the check engine light codes, the stomp test should work fine.

The last question you asked is a very good one, it is something I am working on myself as I am trying to get tracing to work. This feature allows to see exactly which values the DME is accessing at a specific time.

Here is a quick example of what it looks like.

I think the DME looks at the RPM and TPS and if its above aprox 2000RPM it is in the P/T map, anything below aprox 2000RPM and it goes to the idle fuel map.

Yes you want to turn your o2 sensor back on. Doing so will enable the DME to run in a closed loop, meaning the DME will be referring to the o2 sensor for feedback in order to get you as close as possible to the value you tuned for while in open loop (o2 off).

There are a few different maps when it comes to starting fuel. The one you have access to in the WAR software is very simple and effective. It is fixed fuel per RPM, if you're having problems starting your car at any given temperature, you would want to add a few points across the whole map.

There are additional fuel enrichment maps that are coolant temp dependent, these have no reference to your gas pedal. If your car is having problems starting when cold, yet starts fine while hot and the problem is not hardware, then the enrichment maps would have to be looked over. Unfortunately the WAR software does not enable you to make these changes.

Is that an original color?

Sounds like its going to be a bit of work to get things sorted but seeing how much these things fetch for nowadays, looks like you did good.

Any other plans as far as the motor goes?

Although youre most likely using a 179 DME and a Black War chip (Rev 5B), it sounds like you ran into a similar issue as me. Check if you can get it replaced with a different version, the Red (Rev 5A) works great for me on the 413 DME.  I have written to it hundreds of times by now without any issues. Make sure to get one with an ET stamp which verifies it was electronically tested.

Also here is a link to my other thread regarding this issue.

It might seem like a bit of work at first to get everything going, but considering the age of our cars, it's difficult to find one alike. They all have individual things that need to be addressed in order to be able to tune yourself. Regardless, it is well worth it, paying somebody to send you different tunes will take much longer and in the end you will most likely still find things that need adjustment.

WAR Hardware Support / Defective War Chip?

« on: October 13, 2013, 04:36:26 PM »

How do you know your WAR Chip is having problems?

- Car cranks but will not fire up
- Check engine light not working, flashing, pulsing, blinking with accessory on, engine off
- WAR for Windows status: Looking for chip
- WAR Chip not found in My Computer, not detected
- Cannot Read/Read All (Ctrl+R, Alt+R)

Here is a quick video to illustrate one failing.

What does the chip do as of now? Does your PC connect to it fine?

Double check that you still have a functioning check engine light, if it does not turn on while the car is in accessory with the engine off it means the DME cannot read the chip.

What was/is your check engine light code for?

As far as the MAF goes, you should check for the following values:

Key in the on position engine off - 0.01v
Engine idling - approx 0.7v (may be slightly different depending on engine idle speed)
If the problem with the car not being able to rev past 5000rpm is MAF related you would see it peg to 5.00v at the specific load and rpm.

Another easy way to check if its the MAF would be to drive the car with very light load past 5000rpm, if youre able to do it, its not the MAF.

Some of the other things that come to mind would be, ABS module problems and restrictions in the exhaust.

Turbo Tuning / WAR Chip load axis

« on: August 06, 2013, 10:12:46 PM »

Found this information posted by Brody on a different forum and it helped me understand the software a bit more.

Hope it does the same for you!

The Load MS is injector Milliseconds. It isn't perfect but it is the closest thing to let you know where you are at IF you have a good data logger. However, don't be intimidated by the load. It is actually very easy to tune without seeing a little cursor to tell you where you are. Clarifiction: Load isn't one specific measureable thing per say, injector MS will get you close enough and that is why we chose to display that axis like that.

Also it doesn't read one specific cell, it is also referencing the cells around it. the key is to keep the map smooth. If you were to export the map data into excel and make it into a 3D map, you would want it to me as smooth as possible.



If you worry about cell by cell values you can have an ugly, choppy timing curve that will not feel smooth at all. like this:



GROSS!

Fuel is the same thing you want it as smooth as possible.

Now the grand question, where are you? when you are at a steady cruising RPM with no real load on the engine except for that which keeps you moving on a flat surface at the same speed you will be in these columns.



Remember, you want to make changes to the cells in that area at the given RPM because the goal is a SMOOTH map.

When you are accelerating in P/T you will be in these columns



Again, changing these values at the respective RPM will give you the results you need.

What about the columns in the middle? Those act as the transition between steady cruise and accelerating. Some times when you are going up a hill without needing to punch it more, you will move into those columns but again, smoothness is the key here.

The easiest way to figure it out if this explaination doesn't help is to make a BIG fuel change in an area of the map and find it with your foot and the wideband. You will learn VERY VERY quickly how the map works and then you will laugh at yourself for being so scared of it.

There is still some power to be had there. Also, triple check all the vacuum lines, you will be surprised with what you find.

Mine idled between 14-15 with a little crack in the line that runs from the elbow to ICV, and thats with the 100lb tune and zero adjustments to the base map.
