Yes sir, they are finally ready. Even for the 3.6 model. And the tuners ordered through me come with my additional enhanced tuning options built into the pricing.
I'm ready to get some of these tuned and see if they respond like the '12 and '13 models.
Great news but I am only cautiously excited. On an N/A application, especially the V6, not much gains. This device appears similar and form and function to the Subaru COBB Accessport, to which I will refer, for comparison purposes and/or to add detail to my questions.
Several questions for those of us knowledgeable:
What is the dealership experience with them?
Is the device detectable (when "married" to the car in STOCK mode - I know that you do not have to have the unit physically connected to the car) by the tech during the regular dealership service visit (assuming some module updates)?For Subarus it was, if the dealership connected the Subaru Select Monitor diagnostic tool to the the OBD-2 port, it would be detected. It was never clear if it was an automatic red flag or it would be discovered only if specifically looking for ECU parameters/diagnostics.
Is it detectable after the "divorce" from the car? Does it leave some fingerprint, an MD5 checksum alteration of sorts?For Subaru it was/is.
Does the Jeep ECU have a re-flash counter and would this trigger a red flag to a tech connecting his PC to my Jeep?
Does the Jeep ECU allow only a finite number of re-flashes ?[mid-2000s Subaru ECUs were rumored to have 200 re-flash limit, and after that the ECU would be bricked. Nobody managed that - nobody that I know of]
I assume the device uploads a custom ROM to the ECU. What happens to the original, OEM (factory) ROM? Is it saved to the device and it can later be uploaded or is it lost forever? Earlier Subaru Cobb Accessports did not store the factory ROM, if you wanted to return to stock, you would only be able to install a generic one - see below.
Besides the manufacturer of the device, who else has validated the custom ROM that ships with the device to ensure it is free of defects?[another Subaru experience - the original ROM pulled from a factory tuned Subaru Legacy GT by Cobb had a flaw that affected the cruise control. Every single car that ever saw a Cobb Accessport reflash from 2005 well into the 2009, including cars that were tuned via OPEN ECU/ROMRAIDER had this baseline modified ROM with this flaw. The cruise control would not stay on at speeds higher than 75 mph, and it would be disabled by the slightest bump in the road]
Can it be sold and used by another person (after "divorce") or is it a one time use (one ECU only) application? [another great Subaru product that eventually lost out - ECUTEK come sto mind due to this limitation]. If YES, is it Model/Year specific or is it engine specific and a buddy with a Wrangler 3.6 could use the same unit? (Again with Subaru, initially Cobb Accessports initially were model and year specific, later versions were just engine specific 2.5 vs 2.0]
f1anatic - see my responses to your questions in bold.
• What is the dealership experience with them? I think this depends on the dealer, and what you bring the vehicle in for service for. I think most people return their vehicle to stock before they go to the dealer for service.
• Is the device detectable (when "married" to the car in STOCK mode - I know that you do not have to have the unit physically connected to the car) by the tech during the regular dealership service visit (assuming some module updates)? If you have a tune other than the stock tune, yes a tech would be able to see that a custom tune is loaded.
• Is it detectable after the "divorce" from the car? Does it leave some fingerprint, an MD5 checksum alteration of sorts? Once the PCM is reverted back to the stock tune by the tuner, I'm pretty sure it does not leave a fingerprint. My dealer did not ask about a tuner bring connected at any point in time when I brought my Jeep in for warranty work.
• Does the Jeep ECU have a re-flash counter and would this trigger a red flag to a tech connecting his PC to my Jeep? Not sure on this one.
• Does the Jeep ECU allow only a finite number of re-flashes Not that I know of.
• I assume the device uploads a custom ROM to the ECU. What happens to the original, OEM (factory) ROM? Is it saved to the device and it can later be uploaded or is it lost forever? When you load a tune onto your Jeep, the stock tune is retained on the device, and can be reloaded back onto your Jeep at any time.
• Besides the manufacturer of the device, who else has validated the custom ROM that ships with the device to ensure it is free of defects? I don't think anyone does QC testing besides Diablosport
• Can it be sold and used by another person (after "divorce") or is it a one time use (one ECU only) application Yes. When you load a tune to your Jeep it "locks" the device to your specific vehicle. If you reload your stock tune, it "unlocks" the device and it can be used on a different vehicle at that point.
• If YES, is it Model/Year specific or is it engine specific and a buddy with a Wrangler 3.6 could use the same unit The in-Tune DCX is not vehicle specific - you can find a list of vehicle applications on Diablosports website to see which vehicles are supported.
Thank you LTrainGC. Definitely it appears something else to save money for.
I have additional question(s), again with reference to Subaru based on my knowledge.
While my 2005 Subaru doesn't have this, 2007-2009 Legacy GTs have an performance tweak button called SI DRIVE. It its operation, it is no different than what Jeep offers now on the Grand Cherokee: an ECO mode, a NORMAL mode (ECO button off) and a SPORT mode. The Subaru Cobb Accessport allowed for a "Base Map" in conjunction with "real Time Maps" that could be for different fuels (93/91 etc).
How does the Diablosport I-1000 DCX interact with the 3 modes that Jeep ECU management offers:
will it maintain the 3 modes (on the premise that in reality the engine power/torque output curves [tuned or not] are the same in all 3 modes and all that SPORT/NORMAL/ECO modes do is alter the drive-by-wire throttle maps and the revs at which the auto tranny shifts) ?
will it cancel these 3 modes and in reality there will be only one mode ?
will it allow re-mapping of each individual mode in itself, allowing me in essence to re-flash once and upload 3 different tuning files: e.g. an 87 octane ECO mode (default anyways) and a 93 octane performance file for SPORT mode which would give me best power gains provided that I run 93 octane ? I personally do not think this is possible with this OEM ECU - it is no Hydra EMS standalone ECU but I gotta ask.
Also how long is the re-flash process (or rather switching between modes) I imagine in less than a minute.
I'm very interested in this tune as well! First off I would definitely like to know how it affects all the Individual modes as F1 mentioned above. Keep the reviews coming in guys this is plus so far!
Got the DCX I1000 in today. I connected to PC and ran update as specified by Predator including support for 14". Strange thing is that it does not list a 93 tune. I guess it called "diablo tune" because the only other options are 91,89,custom. Loaded tune which took longer than I though it would take (25 minutes ) Spoke to Sean from Hemiferver and waiting for his good deed. I did not feel to much of a difference with the Cantune.
2011hemi,
Did the tune do anything with the transmission? Shift points, fuel cut offs, ect? Also how does the tune effect the different modes (sport, eco, eco off)? With the tune can you still drive in eco mode then put it in sport when you want to nail it?
The tune does not modify any of the ZF 8 shift points or stiffness. Yes Eco mode remains with less of that noticeable pedal lag. Sport mode is very aggressive.
Yes, you can adjust tire size as well as disable MDS.
I'm loving it so far just running Sean's initial 89 tune. I'm down to about an 1/8 of a tank and will fill up with 91 today or tomorrow and do some data logging.
ECO and Sport mode work the same as before. However, I have MDS disabled so that doesn't work in ECO mode now.

How does the tune work like only on Eco mode or only in sport or both. Like can you leave Eco mode on and then when you switch to sport it runs on the tune? Or vice versa?
So nobody has answered this question yet, will the dealer be able to find that the computer was tuned even after u define it to original before u take it in?
