*** It looks like after Diablosport's forum update, the links below no longer work. :( ***


They still have many of them on the Diablosport servers, just no links on the web pages.

IMPORTANT NOTE: if you load one of the newer CROMs (available on the Diablosport website) it may no longer be possible to go back to one of the older CROMs listed above. Only apply a new CROM if you're sure you want to move forward permanently.

This thread should be made a sticky somewhere :)

Great post mnunes !!!!! :rocker:

They actually changed the way the newer CROMs are linked on their website - after these only the newest one appears to still be available. I wonder how long they'll actually keep these files on their servers.

If they do go away, at least I have them all on my PC, just in case.

They take over your computer and then your computer sends waves to your brain so you get infected with Moditis and get addicted to online Charger-related forums :D

What do Crom files do? Is it calibration updates?
 
#12 ·
They're the actual revisions/tunes that Diablo puts out ... my car ran best on the original r18 tune ... it used to chirp the front tires at times .... never had that kind of off-the-line power ever since, even now with heads/cam/headers/whatever else I had done ...
 
#13 ·
I'm gettinig my predator today, do I need any of these files before I do my tune?
 
#16 ·
Ok, thanks. So, what do I need the USB cable interface for?

the newer 21crom for the 09s and 10s is really great. much improved from the r20. just wondering why diablo deleted the option to turn off the egr.:confused:

I think they did this to keep the EPA off their back. Disabling the EGR is essentially tampering with federally regulated emissions equipment. If they keep their software clean less chance that anyone is going to hassle them about it. They did leave the ability for custom tunes to disable EGR but their canned tunes don't touch EGR anymore.

I haven't ran but only one crom the 21 but I have an '08( no VCT), is there a better one to run? I remember the posts of ppl switching croms on the '06-'07 model LX's and noticing a difference at the track and some using the butt dyno!!

Whats up the best CROM to download for an 06 Daytona (topbanana). My buddy has a predator that we were trying to figure out but it wouldn't work on his car needed to update or something like that but diablos servers were down or something cause it kept giving us an error....

Please chime in if you know anything....

THanks

I recall there being a process for reverting the predator back to an old CROM, is there a link on a how to for this? I believe you had to reload the stock tune on the car, upload the CROM and blah blah blah...
 
#28 ·
Each time you download an update you should save it. This is in case you want to go back. For example I have all 4 versions of the V6 tunes.

So if you dont like the new version you do just what you did to go forward, you go back to stock tune, update the tuner to an older tune, and reinstlall it. No different for going back as to going forward, you just need to save all versions.
 
#29 ·
Mostly true with one small exception: if a newer CROM requires you to update the CALID (calibration ID) on your car, after that you'll only be able to use CROMs that support that newer CALID. As far as I know once you upgrade the CALID you can't downgrade it since it's not a file that you can save and reload later.
 
#30 ·
^^^^ very true.


I wish I never "upgraded" to r19/r20 from my tuner's original r18, back in Dec 2007.

I still think r18 was my best tune so far ...
 
#32 ·
Not by default, but there is a place in the menu to turn it off or on.
 
#33 ·
Why can't I open any of these files???
 
#34 ·
You dont need to open them, you need to download them to your hard drive, then install dsdownloader and use it to get the file and put it in the tuner, after the car has been restored to stock tune.
 
#36 ·
Make sure you have the right file, some peole get the wrong file. They do make a v6 one and v8 one. Next if you have an older tuner it doesnt have enough memory for the latest tunes. Check with DiabloSport support on that.
 
#38 ·
What error does it give you?
 
#44 ·
i just got my predator and i updated it through the DS website, however whats all this talk about crom files? do they need to be downloaded from like before aswell ? or is just updating to the newest version okay?
 
#45 ·
The CROM is the program that comes loaded on the Predator. Periodically Diablosport will release an updated CROM that has new features or updates, usually to support newer cars or changes to older models.

It's not necessary to download the newest CROM, and sometimes it's not even desirable. For instance, CROM 9r18 was the last CROM to support disabling your O2 sensors and disable EGR on the HEMI. DS made this change to newer CROMs to comply with various EPA regulations. If you have a Predator with a newer CROM and have your EGR system removed, or you have LT headers, you no longer have the ability to disable or tweak those systems unless you go to a custom tune which costs $$$$.
