Ok I have been working on this for a couple of weeks now and have come to the point of mental breakdown! :mad:

I have setup a tune that will help me to replace my stock trans sooner than later and I just cant turn the power down any more. :)

Anyways, when I load this tune with out any DSP programing or calibrations it will flat out rip. Thats great, thats what I want.
Now the problem is when I copy the same calibrations into a DSP5 tune it SUCKS!. What I am saying is the power is not much better than stock. What the hell am I doing wrong or not understanding.

I have copied and pasted every cell and calibration that the DSP is requesting in the custom calibrations and it feels like I am back to stock. I montior the DSP voltage and switch number and have modified the main injection pulse at idle to give rough idle and it works, except for making any power.

One thing I have noticed is within probably the first 15% of throttle the tune works then power falls off.

I have included a couple of screen shots which show the same number for the DSP tuning if there are any questions about it.

I need some help here. I will email anybody the tune files to try to see if they work on a different setup. The EFILive is great and I would definitely enjoy it more if I can get the DSP 5 to work properly.

Email the stock tune and your DSP5 tune to me and I'll take a look.

Did you try basing the DSP5 off of your hot tune vs your stock tune?

I created the DSP5 using my stock calibrations and running script to populate the DSP5 calibrations. I then copied and pasted the requested calibrations the DSP5 tune requires from my "hot" tune into the required fields.

The base "non DSP calibrations" are all stock. I have only modified the DSP or Custom Calibrations.

Sounds like your DSP5 tunes are being limited by some of the factory tables, which do not get modified within the individual DSP1,2,3,4 tables. Unless you know which tables are capable of limiting you it may be easier to base the DSP5 off of your big tune instead of you stocker and see how that works.

I am beginning to believe this is how I am going to have to tune this to work properly.
When switching between the tunes, the initial change is noticed and then it seems as though the calibrations are being limited by possibly the base calibrations like you say. Now the hard part is knowing if this is correct or if there is a communication error behind the scenes.

Also make sure the units match from the tune you are copying and the stock tune. the first dsp5 tune i built, I ran the lly imperial script and copied metric tables into in. it did something similar to what you are experiencing. O yeah and as said above use your "big" or "race" tune as the base so there are no limitation on it.

Which way are you trying to program? little red arrow or big red arrow?

Need to load it as a new OS, so you want to use the big red arrow

I tried two different setups last night and logged information from a couple of settings and still have poor results. The programmed power into the DSP tunes is less than commanded, even stock is less power.

First I ran the DSP tune with stock base calibrations with modified DSP tunes such as a economy, hot, tow and a rough idle for fun and the results were not good.

Second I setup the base calibrations with my hot tune and set the DSP to economy, stock, tow and rough idle again. Still poor results.

With each tune file I would do a full flash, start and drive for a little ways, shut down and do a calibration flash. I monitored the DSP Pids and they change like they should. I do the ecm flashing with the DSP set to off.

I logged the second tune file that has the Hot base tune and was able to see some interesting things take place. I immediately noticed the fuel mm3, was less than programmed into the tune file. This occured with each DSP tune. I was tired and not able to check the other parameters within each DSP tune calibration so I dont know how they compare to the stock scan files I have or to my Hot scan file. To see the differences I replayed the DSP tunes and stock scan files at the same.

Did your stock position (big tune) have the expected power output? Double check that your cal_link.txt, located in \Program Files\EFILive\V7\Configuration, is set up correctly or you will see incorrect links and corresponding values within your logs.

The base "hot" tune had the expected power output.
When I get a chance I will check the cal_link.txt. What am I looking for with this? Is it in the configuration file? not sure.

Did you get something weird plugged into the DSP staging tables by chance?

the file is under configuration, but is there something in specific to look for?

Interesting. I think I'd send all the individual tunes you want in the DSP5 tune to someone you trust that knows how to build the DSP5 tunes and let them try to create a DSP5 tune for you. Not because you necessarily don't know how to do it, but sometimes fresh eyes help catch a problem that you may be inadvertantly overlooking.


Best of luck.

Working on this now.

Make sure you saved the tunes with the units in both tunes in either imperial or metric before reopening them and running the script.

More often then not some of the tables are populated in metric and the script when it ran could have made the tables wrong.

I have a feeling it is a simple thing you are overlooking.

Well I have fixed my problem.
With help from others behind the scene here I was able to find my DSP calibrations had a mix of metric and imperial units. The numbers were correct the unit was switched. After some time of resaving and readjusting to all imperial units, the system works great.

After looking at so much data I overlooked the simple things and didnt notice some units were using metric and not imperial.

It makes a big difference when everything is communicating properly. :)

Thanks for help and input.
