Thought I would start this thread in an attempt to have a dedicated source where anyone having information to share or questions to ask about the Diablo Predator U7135.It seems that throughout this forum there is an immense amount of scattered information that is very useful but difficult to locate at times.Perhaps if everyone can post here it will create a one stop shop where we all can access and utilize the power of the Predator more efficiently.
Kick it off with some questions about the U7135.
1.I loaded the CAI 91 Octane tune into my 09 Auto R/T.Before doing so I modified the cooling Fan setttings for a 180º T-Stat and disabled the MDS.I Then uploaded the previously mentioned tune.After doing so I noticed that the Exhaust Gas Recirculating(EGR) parameter was set to 'Off'.Does this automatically happen when disabling the MDS,changing the fan settings or loading a canned tune?Is it better from a performance standpoint to have the EGR off or will having it off put the engine at risk in any way?
2.If I later wish to change additional parameters within the 'Modify Tune' menu do I have to reload the entire tune again or can I just go in and make the changes to the already loaded tune?If I have to reload the entire tune do I have to start from scratch and reload my stock tune first then make all the parameter changes in the canned tune and reload it to the PCM?
3.What do the 'REV and Speed Limiter' changes do?What would be considered safe settings if modifying?Will these setting changes work on the R/T Automatics?
4.In the 'Quick Adjust' menu under the 'Shift Points' parameter it states that the it will raise the shift points by a set values on the 5.7L: 1-2 shifts at 5,800RPM,2-3 & 3-4 shifts at 6,000RPM,...but it does not mention anything about the 4-5 shift,:scratchhead:,...Am I missing something here?Also,do these shift points apply to the 5.7L Automatics?
5.Does the 'Auotostick Auto Upshift' when disabled still allow tthe transmission to downshift?Is it safe to change the 'REV & Speed Limiters' if the 'Autostick Auto Upshift' is disable.
6.Is it necessary to update my Predator to the latest 9r23b crom revision file?I currently have the 9r17 revision file installed.
7.After I complete my modifications I will be doing some data logging for custom tune to be created.Should I data log with the CAI 91 Octane tune that I have already loaded in the car or restore the original stock tune from the Predator to the car and then do the data logging?
8.Has anyone had success in turning off the 'ESP' under the 'Quick Adjust' menu on an Auto R/T?I have also heard this off setting referred to as 'Dyno mode',...should we be running our cars on a dyno with ESP fully off?
I know there is a lot here to answer but I'm fairly new to this modification game and want to understand what will work,how it works and if there may be any high risk in changing certain parameters.
Thanks in advance.
