In the market for DSP, have some questions and concerns - SRT Forums

glenb1991 · 10-04-2009, 11:08 PM

Ok guys, well about my car, its a 2005 SRT-4(Obviously), i have a Godspeed BFMIC, FM WGA, Hallman MBC, !PCM Controlled Boost, Ebay SRI, Prosport Digital Boost Gauge.

So I sold my stage 1 last week, and im already sick of driving the stock pcm. I wanna bring the boost back up to where i had it before. So heres my questions.

I'm obviously new to tuning, so id be looking for premade tunes, to go with my mods. Who can do this, and how much?

Can dsp log any kind of AFR?

If not, will a wideband really be necessary if i use the "93 Octane Tune", or will it basically keep everything where it should up to x amount of boost?

I want it to be basically plug and play, like the stage 1 was, but id also like to be able to learn it and do my own changes later on. If i load the 93 Octane Tune to the car, will it basically be plug and play, and i won't have to worry bout my car grenading at lets say 20psi spike? And how hard is it to tune, from everyone elses perspectives?

Obviously its a good resolution since its so popular, hence why im looking into it. i just want the clarity on these questions, since it is my daily, i dont wanna have to spend a while getting things right once i get it. So any help would be appreciated, and any other info thats available please lemme know.

We can do it and it varies in price from $88 to $250 for the tune that you want.

No the DSP cannot "LOG" AFR's but the Trinity can (you still need a wideband, check out our deal on the Trinity and LC1 set up).

The 93 tune is a good starting point, if you want to mess with the tune or add boost you will want to get a wideband. If you get larger injectors and decide that you want to get an E85 tune or race gas tune built... you will need a wide band. Eventually.... your going to need a wide band.

It is PNP, but your going to want to keep the stock WGA on the car as well as stock boost control if your running the 93 tune, if your running something different you will want to get a wideband. The stock injectors seem to give up around 19 psi on most cars (some can go higher but with your mods, your going to be done around 19 psi.

If you keep your current WGA you will need to get a canned tune and make sure that the car is running 100% before tuning (new plugs, boost leak free, ect). I would also recommend a fuel pump rewire due to it adding .8 to .5 additional AFR's (fuel) up top. Then I would look into getting a set of larger injectors for the car so you can really turn up the boost. Hope this helps, thanks.

yea, heres my current want list:
DSP
Wideband
Fuel Pump Rewire
Stage 2 Injectors

Id prefer to do it in that order. So i guess the only thing i wanna verify from that is..

I can just use the 93 tune, PNP, but ill have to use the stock wga and PCM Controlled Boost? Im sure i could throw that stuff back in if i can make similar power, without the wideband or injectors, as i did on the stage 1. Would that be possible?

lyncoo · 10-05-2009, 10:58 AM

john at ptp will take care of you. the trinity and lc1 combo is what you need

to me it looks like the stock wga works best with the dsp. there holding just as much boost with the dsp with a stock wga than a aftermarket wga.

is there any way to use an aftermarket with it? cuz i dont wanna get rid of it or take it off if possible, plus it being stronger, even if i lowered the preload to the abilities of the stock onee, 4 psi i believe?

Gizmodo · 10-06-2009, 08:14 AM

Yes you can use an aftermarket WGA with the Predator or Trinity, but you will need a CMR tune for it.

with the dsp it doesnt matter what spring is in it it will hold the exact same thing. if you have stock or aftermarket. save that money and buy something else to help hp wise to go with the dsp

This is not true. With any WGA other than the stock one, the WG Duty Cycle needs to be updated. The best solution for PCM boost control is to use the stock WGA.

5k-6K there's very little difference at WOT

0-5K Big difference = a stiff wga will overboost without a CMR adjustment, like Giz said

I wouldn't waste the money on one, no. But the op said he has a FM so its irelavent.
