I did some more testing on v3 with regard to the droop on deceleration.
V3 (no corrections during dashpot event)
V4 (corrections during dashpot event)
Whoa! It aggressively increases the dashpot value. It still remains a flat line though- how was this implemented? Never get a droop now. I can lower my dashpot value from 12 to a much lower value now.
I also rewired the ECU as described in the previous page. The ECU now has full control of the AC with independent delays on the AC clutch and fans.
My current idle graph
The AC switch-on can be seen with the status 4 line. The AC clutch activates 0.333 seconds after, and the AC fan 4 seconds later.

With the rewire, the timing of the AC clutch, AC fan, and main fan are all under the control of the ECU! All extra solenoids and associated relaays have been removed frm the car.
A snapshot of the current idle tune:
IMPT NOTE: 3.1.3 from which the modified FW was based has a serious issue with the injectors at >90% duty cycle or >6000RPM. Use with caution. Awaiting a fix for this.

As requested- data comparing the dashpot actions with and without the AC idle up code.
Turns out, if I turn off the AC idle up, status4 does not start counting, and the AC compressor does not engage So I just kept it on and set the adder to 1.
AC adder 1, voltage correction factor 0
AC adder 13, voltage correction factor 18
Overlaid and magnified:

OK. Tried installing the RX8 injectors along with the M-Tuned dual feed rail. I thought I was finished- when the fuel pump primed, fuel started leaking from the injectors and the Y-adapter!
The Y- adapter has this threaded plug in the center, and it leaks like crazy! Plus a gorilla put it in- I can't remove it! If I use a vise grip, I'll end up mangling the anodized finish...
The leakage at the injectors- well that was on me! It was really tight, and I forgot to lube the o rings before pushing the injectors in. Yep, you guessed it...
The last thing I need now is to worry about a fuel leak, so I wimped out and used the stock fuel rail

Ok next issue. Soldered a 2.2k resistor into r14 of input 1 so I can run 1v--input 1---pe0 (launch/clutch lockout). It had no resistor because it was previously used to connect 1q--1j (AC circuit)
Anyway, I am using input 2 to connect 1q to pe1. I peeked at the input 2 area and found that r17 was missing! Do I need to put a resistor there? What type? What happens without it? :/
