I am going to call BS on this:
"I spoke with Adam Marrer of CoreTuning earlier. He mentioned that he's seen that some Tweecer devices do not work well with the last generation of EEC-V computers because of a potential memory space addressing limitation."
Please don't let a competitor give you bad info and pass it on here. Now you are saying strategies are not broke-out when they are supported. I am using REAC4 and REAC0 is also supported by Tweecer.
Let's be clear, I am running and tuning with an EQE3 EECV utilizing the REAC4 strategy and a Tweecer RT. I have tuned and data logged with his CalEdit and CalCon software and I can switch between 2 tunes There is no additional cost for the strategies if they show as supported, REAC0 is supported and is already in the Tweecer CalEdit software!
For the third time, it is simple to READ the EEC in CalEdit and start tuning. I would have a working tune for you and feel I could within a couple hours if the mechanical stuff is sorted-out.
An exception to Tweecer fee's is that Mike charges a $75 support fee if you bought used. I have thrown him some cash after he willingly helped me tune three different vehicles with the same Tweecer RT. The web site group support is free. There are no additional charges unless you want him to tune for you and that is reasonable as well. He starts at $75 to get it running, a mid level tune at $150 and $300 for advanced. Maybe you need some of his help.
Oh come on, I'm not going to throw in the towel that easily!
I have the same sentiment about the Tweecer hardware... I've been using 2 units for over 20 years and I've never had any issues with them. In fact, I've confirmed that I've got the 2-4 bank thing working now and have been running down tune related problems that are plaguing the startup. The REAC4 stuff is working for me, but I've not been able to get READ0 to work, but it's not important. The reason why is that in solving my tuning issues I have 3 separate EECs setup with tunes for the Mountaineer for testing! I had to do this because I have been plagued with fueling issues and I think I may have had a breakthrough in understanding last night.
The EECs I have setup currently:
- CDAN4 EEC-V: Using a JZP3 box and Sailorbob's definition for Binary Editor using a Quarterhorse; I'm using this because I've successfully stood up a high compression 408 stroker in front of a 4R70W in a classic Mustang before.
- REAC4 EEC-V: The stock EQE3 box and setup with the Tweecer RT hardware.
- READ0 EEC-V: Junkyard EQE3 box that my friend and I updated to FLN0 on READ0, setup with the Quarterhorse.
I have been able to rule out many tune related and hardware related issues by testing each of these setups. For example, the READ0 definition I have from CoreTuning does not log ACT, ECT or even RPM correctly. Ruled out that the readings it was acquiring were erroneous by testing on the REAC4 and CDAN4 box. Working with those folks on updates to the definition to get it working.
In any case, the breakthrough was initially the PRLDSW setting - mine was set to 1, but really needs to be set to 0 to use FN035, which is the volumetric efficiency curve for the engine. With that set correctly, I was able to get the load under control, finally, but I still had the fueling issue. The EEC's load calc is directly responsible for generating the appropriate fueling, so having proved that load and fuel were now decoupled, I knew I had some other kind of fueling issue.
The 2nd breakthrough (I think) is the fact that the EEC-V cannot handle injector slopes greater than about 56 lb/hr. Since I'm running 80 lb/hr injectors, I will need to either reduce injector size so I can use datasheet values directly in the tune or scale the entire air/fuel model to accommodate the larger injectors. I did not have this problem with the same injectors in my Fox Mustang using an A9L box because I started with Decipha's A9L2 base tune, which calculates the correct scaling in the background for oversize injectors. Of course, I do not have that facility for the REAC4 or READ0, so that is what I need to focus on next. It's easier to make adjustments in software, so I'm going to see if I can scale the 80s down, but I did go ahead and order some EV6 24 lb/hr injectors that function as 38 lb/hr units at 65 psi.
