Help with DSP tuning my Stage 2 SRT4.

Post by KEGMotorsports »

I'm having a few challenges and hoping someone here can help me. I'm trying to tune my 2004 SRT4... it's a factory Stage 2. Stage 2 ecu/toys capable, stage 2/3 injectors, 3bar tip n map, stock turbo, stage 2 wastegate, 3" exhaust, solenoids are connected.

Here's where I'm at right now...
ISSUE #1) I connected my dsp and only saw a 91 & performance tune. Not seeing the expected 93 tune I figured my dsp needed to be updated, using my pc I realized it was actually on the newest crom, but I reinstalled the newest crom anyways. EXCEPT NOW... my dsp only shows a "performance tune", still NO 93 BUT NOW no 91 EITHER lol... ahhh!

QUESTION #1)
How can I get the 91 tune back and the 93 tune?
I think I read the dsp is supposed to read the ecu and it makes the appropriate & applicable canned tunes available, that true?

QUESTION #2) Considering I hear the factory Stage 2 ecu & tune is pretty good... So what tune do I want to flash as my base the 91, 93, "performance tune" or do I want to choose the "modify stock"?

My ecu is toys capable, but I currently DO NOT have them, I can easily get the harness & bezel though.

QUESTION #3) Do I even want them, meaning if I tune with my dsp, will using any toys switches be good, or will they just conflict?

Please help... thank you

1. The diablo tune is for a minimum of 91 octane.

2. You would want to use our tune ideally, thats why most people buy the device :)

3. Toys will still work as intended.

I'm sorry let me clarify I'm sorry let me clarify, I'm referring to the 91 tune and the 93 - I always Premium gas.

My reason for asking about using the Diablo tune was because your tune might be better than stock but might not have been better than factory stage 2. So I asked cause I wondered

So my last dilemma is how do I get the 91 or the 93 tune on to my DiabloSport Predator, where can I download them from. I thought I read the dsp itself has Sam hardcoded n and is that during the marry process it would make the appropriate tunes available.
- I ask because it used to list in the Predator a 91 tune and a "Performance" tune, but since flashing the most reason update to the tuner I now only have the performance tune and neither the 91 or 93.

Please advise where I can get them.

the tune you see, the one called diablo tune, is the only one we provide, it was developed on a S2 car, to provide more power (~30whp over stock) on the S2 car with an S2 PCM, when used with premium fuel.

So nother question, raising the boost... after the performance tune is installed from the dsp I can raise by %, but is the % raised based off the canned perfect tune, or off what the current tune is. What I'm trying to ask is, when I raise the boost say max, believe 50%... save n write tune to ecu, then repeat, would the 2nd time be raising the boost by percent of the current modded tune?

Or maybe I should just ask... what's the simplest way to raise the boost to 19psi?

Yes I'm using my solenoids.
