Delta Force Tuning Forums

Where are you located and what type of vehicle are you tuning?

To purchase a new Bullet, you will need to connect the Interface to your pc and then open up the Bullet Utility program. Once open, click on "Get hardware fingerprint". This will pop up a long code (fingerprint). I will need that along with payment information and then I would give you a key in retu...

If you use our Special Forces tuning software then you will just need to know what modifications the car has. Special Forces software will ask you a bunch of questions and you just click on the right answer. Based on that, the software will adjust fuel and timing. After that, you do have the ability...

It's not always a stock file that the Interface box "locks' on to. Sometimes peoples cars already have a tune in it when they first use our software. If this is the case then only the tuned file will return the Bullet. Only the original file that gets read out of the vehicle (can be stock or modifie...

What version is the kit you bought? There should be a small round sticker on the Interface box with a hand written number. If it's v13 or older then the kit would need to be sent in for updating to work with newer pc's. The charge for this is $100 plus shipping. If it's v14 or newer then they you ju...

We're open from 9-5:30 eastern time.
Version 23 of Special Forces doesn't require any keys. Should be able to just install.

I'm sorry, we do not offer that for that year, make & model.

We do not have a product called "Sniper" so I'm not sure what you're referring to. The tuning products we have are: - Special Forces - Commando - Delta Force The Special Forces is powerful but simple to use for OBD-II vehicles*. It's basically a questionnaire that will ask you about 30 questions abo...

"vents back into the intake before the turbo" Back in front of the MAF or after?

Is there a blow off valve installed? If so, is it before or after MAF and is it dumping into atmosphere or back into intake?

Depending on year make and model, some of the adjustable parameters aren't supported.
What type of modifications are done to the vehicle?

Assuming everything is sound with the engine, sensors and no vacuum leaks, you can try this. Because your stft are negative and your ltft are positive we really don't know which way to make the adjustment. I would start be adding 5% fuel. You would make this change in the MAF transfer function. This...

Obviously you want to be as close to 0% as possible but those numbers are still within specifications (10-15%). I'm not seeing any issues there. Are the trim numbers jumping around (fluctuating) or are they just staying solid?

What's year, make and model?
What is the LTFT values?
What is the MAF voltage at idle while LTFT are high?

Should be version 19 or higher. It's possible that v14-15 may be ok too but I'm not 100% sure. We no longer have the older versions to our disposal so I'm not able to confirm that.

To know what version you have there should be a small round decal on the interface box with a hand written number. If that's not there anymore then you would need to install the software and open it up. Once open you can go through the Special Forces questions to see if the IMRC question is there or...

Depending on how old your tuning kit is, you may or may not be able to disable IMRC with Special Forces. I know the last two versions did allow for IMRC deletes but older versions did not.

Unfortunatey, as it turns out, the CDAN4 calibration is notorious for being rich and is very difficult to set AF perfectly. It's going to require a lot of tweaking. The MAF meter plays a big role with getting this calibration running good (meter location, blow through, draw through, any pipe bends j...

Unfortunately that 127mph is not able to be raised. Have you looked into (or heard of) the OptiShift (now called US Shift)? http://www.usshift.com/usq4.shtml

I can email you the program but I'll need to know what name it's registered under.
