sct vs dsp - SRT Forums

nfrancis1 · 10-29-2009, 03:32 PM

so, im looking into getting either a dsp or sct flasher to tune with and im kinda having trouble on the decision. i was wondering if you guys could chime in and maybe answer some of my questions/make some recomendations. i know that with a dsp i have very limited control of the parameters i can adjust and the ones i can are only the WOT tables without the cmr software, as well as it gives me the ability to be able to datalog. this is correct right? also, if i wanted to get the cmr software im looking at about 2 grand just for that, so realistically that is probably out of the question for me now. as far as the sct is concerned, do i have the ability to adjust anything on it, or does that require the prp software? im kinda confused about that point. i know it wont datalog, but it seems like other than that, it's a great tool. if i need prp software to make adjustments, how much am i looking at for that also? anyway, any insight as to which way to go would be greatly appreciated, as well as experience from people who may have used both of them. sorry if this kind of thread has been started before (im sure it has) i just couldnt find it. thanks for your time guys, and any info is, as always, greatly appreciated.

Yes, you need the prp to do ANY tuning with the SCT other than canned, or shop made tunes unfortunately. However the SCT+PRP is much cheaper than the DSP+CMR and I'm pretty sure both cmr and prp access the same tables of the pcm for the most part.

I think you should really look at how in depth you want to be able to tune. Want to tune EVERYTHING.... SCT+PRP. I got mine for 400 shipped used in the forums. If you're satisfied with limited control of boost/fuel/etc.... definetly the dsp.

The DSP alone data logs and allows adjusting of major parameters for generally around 300 shipped from the forums.

The SCT+PRP... if you can find it for what I got it for(400 shipped, without haggling, that was the posted price).... then you will need something to datalog(I got my scan gauge 1 month old for 180 shipped) so.... around 600ish total if you can find it....

DSP+CRM...... 2k+? Out of the question.

.... that's my 2 cents :-]

dsp is 299 shipped and does 100 more things that a sct. dsp datalogs everything but afr

This is an ignorant DSP user, don't listen to him lol

Without the cmr package sct+prp is better in every way with the exception of no data logging :-[

Now... if were talking just the units... SCT vs DSP... get the DSP, cause you can't do shit yourself with just the SCT.

Also, the scan gauge has aux inputs for your wideband.

This is an ignorant idiot, he just owned himself.
canned tune with a dsp you can still tune +- 10 fuel and you not stuck with a canned tune during weather channges ect.

Reading owns you lol.

I already said unit vs unit go with DSP, and it depends on how much he wants to be able to tune. Some of us a little more competent than yourself prefer to do a little more tuning that +- 10% fuel

not trying to start a fight guys, just looking for honest opinions. btw, other than datalogging, what are the other 99 things the dsp can do over the sct w/prp?

i take back the 100 more things its just 10 times better. i think sct stop upgradeing the sct for our cars or something like that

Haha.

Like I said, it really comes down to the extent of tuning you want to do. You can change the majors(fuel/spark/boost) AND data log with DSP.... and you can always get canned tunes, etc... I think it was ptp or some one is doing free canned tunes right now.... If that's enough for you, I would def say go with DSP, BUT if you feel the need to tune every last detail....(and what won me over to PRP was the ability to tune boost by gear/speed/rpm/etc) go with SCT+PRP+Scan Gauge.

agree

ptp is doing free tunes, he swamped by it but yes he's getting to them

i currently have a dsp and switching over to sct..only reason im doin this is because there is only 1 company in illinois that tunes diablo,and shitload of them tune sct.so if ur intressted in a dsp i got one for sale

Lyncoo , are you aware that the SCT+PRP gives you ALL the access that the DSP+CMR gives you ? Basically , PRP eliminates the need to have somebody build tunes for you . You claim you dont need that because you can do small trim adjustments yourself , but thats not the same . change anything in your setup means you will have to get a dealer to build you a new tune . Not so with the SCT , if a CMR tune dealer can do it , a SCT prp owner can do it themselves , anywhere , on his/her laptop , and keep as many tunes on a thumbdrive as they wish .
Of course it goes without saying , if you dont have the required knowledge to do this stuff , perhaps the DSP/Trinity would be a better choice .
But if you want complete control of your ECU , and you want to have access to different stage0,1,2,3 base-codes , full adjustability , ect , the SCT setup is more comprehensive .
SCT has NOT stopped supporting the srt4 platform , they simply cancelled any release of datalogging software for their DCX products .
Not trying to start a ECU programmer pissing contest here , just trying to state the facts . I often reccomend the DSP for some owners , it depends on their tuning knowlege & goals .
