Since I finally have a major update I'm starting a new thread as a continuation of the first one, which grew quite long! Here's a link to Part 1 for future reference.
So today I pulled my car back out of winter storage, and I was able to test the beta VQ30 fix Greddy gave me a few days ago. Bear with me, this post is probably gonna get long. I'm going to break it up with section headings, but as a preface I will say that I can verify that every major feature is working on the VQ30 engine!! Man I'm pumped - this has been a long time coming - 8 months - and lots of LD phone calls!!! Oh, I should note that all my testing has been done on a bone stock 1998 (A32) ECU. Ok here we go....
Setup
-In order to use the crank signal to pick up rpms and track ignition timing, the EU must be wired to use BOTH crank sensors. It does not need the cam sensor to be inputted. The crank POS signal should therefore be inputted on the EU crank line (crank angle (Ne)), and the crank REF signal should be inputted on the EU cam line (cam angle (G)).
-The following pic shows the settings for the VQ30 on the Vehicle setup tab. Note that the VQ30DET is selected and that there is now a NS_5 crank type. When I first fired up the car I idled it, revved it, and drove it around for quite a while with the EU logging rpm and timing and compared it to what my Consult scanner was showing. Greddy got it right; they both matched very well. I didn't have to add in any offset on the angle at all (as you can see it's zero in the picture).
New Features
Haven't studied it in detail, but:
-Timing adjustability will be bumped up to +/- 40 degrees (EDIT: this was incorrect.. it is +/-20)
-There are 2 new maps that allow timing adjustments based on water or air temperature (previously there were only fuel maps, not ignition)
Timing Adjustment
-Both retard and advance work. I verified both physically with a timing light. Even without the light the lowering and raising of idle speed with retard and advance (respectively) was obvious.
Extended Rev Limiter
-As Icey proved over the winter, this works well enough although it is not perfect. Unlike Icey, however, I went quite a bit higher so there's no doubters. The log below shows my car getting up past 7600 rpms in 2nd gear. Remember this is a stock ECU, with a 6500 cut normally. Do not look too closely at the fueling here, I didn't have time to get it perfect, just coarsely fueled and quite safely (and overly) rich around 10.8 to 11.5 A/F (DEK injectors). That little dip right at the stock fuel cut does not show up on the WB logging as my A/F never gets above 12. Also, the timing log seems to get a bit finicky, not quite sure why, but I don't think it exactly reflects what was happening as the car pulled pretty smoothly up past 7500. If you sort of take a trendline or average there seems to be between 26 to 28 degrees from the stock cut up to 7500 so I suspect the timing map continues with reasonable advance to at least 8000 rpms.
2-Step Launch Limiter
-YES!! I love this feature. Works like a charm. Check out a small video of it in action: 2-Step Video. Note that the 2-step dumps raw fuel out the exhaust so you may not want to subject your cat to this... test pipe recommended.
That's it for now.. I need to report back to Greddy and talk to them about a few things. I should have some more news in a couple days hopefully.
Just to be sure though, what exactly needs to be purchased apart from the EU unit itself and the harness? How has the add-on for the 4G crank signal and such been implemented? A seperate external add-on? Or does something need to be soldered to the board? Too many question?

I must say thank you. This will be (arguably) the best ecu upgrade for us. No More JWT w/ 6 month waiting period etc.
I was very close to purchasing a VAFC2, but whats the point when the EU can do it all!

That looks awesome, great job. I need to go reread all that I've missed in the other thread now...

Dan is the Man!!! To be completely honest, I never thought Greedy would get it right, or care enough to get it right. I've been researching Greddy blue, SAFCII, and the VAFC. Now it looks like EU is the answer. Thanks again for your hard work, time, and perseverance.

Answer to what though? While Dandys accomplishments with the EU should not go unnoticed, I think some of the EB capabilities have been overlooked.
I will purchasing the EU through Forgedinternals.com and I was wondering what do I ask for when I order the Emanage? What does this "box" consist of ?? I know this guy at Forgedinternals knows Kenji and has been in contact with him. Did you just update the software or is it hardware ??
Can someone explain the point to the "2-step Launch Limiter" ?? I Dont know what the purpose of this is for ??

It's important for tubo guys because it allows the car to make boost while standing still. Depending on how you have it set you can launch at almost full boost.
JWT NA is still "good enough" for those who want a few Hp NA, and don't want to have to deal with a custom tune and wiring it all up, but for those NA people who want the most power and customization and just about every boosted car should probably opt for the EU or some other system if they so desire.

For the time it takes to get your JWT ECU you could learn and become a professional installer for the EU.

Correct and it isn't fixed so you have to take what you get, its totally tunable. ie Don't like the rev limiter then adjust it, do a mod and need to adjust your a/f, too easy. Try that with JWT. Plus a host of other things it does the JWT doesn't.
Newbie here. So what's a typical cost? $600-ish with the harness purchase?
I assume you hook it up and it will run the stock program until you start changing things? ie... if you totally screw up, you can revert back to stock?

This is for ANYONE who wants to make the absolute most out of their setup, whether it's n/a, nitrous, or FI.
