F-con vs Haltech

Ive had the Haltech and had two exceptional tunners play with it and still couldn't get the tune right.
Switched to the FCON Vpro v3.3 and it literally was a night and day improvement on driveability and overall smoothness of the tune.
Fcon is more refined and when switching maps its just the flip of a switch, not pulling out your laptop and changing maps.

Reverse engineering my Fcon install...
Don't know if this needs new thread but...
Need some help with Fcon install set up. I am trying to figure out the how and why of the install...cut/spliced wires...
Questions are referring to the blue HKS A/F Knock Amp box with 16 pin input.
16 Pin "out" Plug from the blue HKS box---
1) Grey wire not used...this OK??? ...normal???
2) YEL/BK wire goes to ECM pin 14 Left Cam Sensing- use only one wire for both cams???
3) The two green ground wires (to ECM pin 1), the Y/B wire Cam Sen. (to ECM pin 14) and the YEL Crank Sen. wire (to ECM pin 13) all have been spliced into the main engine harness just upstream of the main oem harness plug ...is this normal???
4) Also, the White Knock Sen. wire (to ECM pin 15) is spliced into the Fcon harness between the "Fcon to oem engine plug" and the "Fcon to oem ECM plug(s)". Is this necessary and normal???

Good info. That brings up yet another question. I have my F-CON configured to automatically change to a scramble map when I turn on my meth injection system to compensate for the added fuel. Both the injector and ignition timing are adjusted but, unfortunately, not with as much granularity as the base map. Does the Haltech not have the ability to do this?
This is a big issue that I've been harping about to the Haltech guys in Australia for over a year now. If there were just a few more inputs, you could play with some of the compensation maps since every map has configurable axes - very flexible. There has been some talk of an "I/O Box" with 16 inputs/outputs but I was expecting it at SEMA this year and heard nothing about it. So I'm disappointed on this aspect - I have lots of sensors I want monitored by the EMS. 
I know this thread isn't about this EMS, but the ProEFI 128 seems to have fantastic hardware. The software continues to mature. If Haltech doesn't come up with something soon, I may consider a $3k expenditure... If E85 were more prevalent here, it would be more enticing.

Active knock control was added to the Haltech in v1.06. The internal map sensor is good to 22 psi. The internal PWM output for the boost solenoid works quite well and can be setup as closed loop or open loop. You can set up two axes for compensation to base boost off things like speed and wheel spin for example. I still had to buy Osiris to change my idle, speed limiter, and to try to set AFR targets to avoid CELS (ended up just disabling them). With the Haltech you will get a CEL for cams because the stock ECU is not in control. InjectedPerformance provides a package deal I think for an Osiris reflash along with the Haltech to get rid of little annoyances like that.
Dil, I'm not sure what was going on with your unit. It does seem that there is some issue with early 2003 cars - perhaps related to cam phasing - str8dum1 and blackbird are the only affected to my knowledge though.

No. There are no as in ZERO (0) user definable inputs. This is a big issue that I've been harping about to the Haltech guys in Australia for over a year now.

I have one more question relating to the cam phasing control. Hopefully we will be ready to tune my car by this time next month. As noted, I can play with my cam phasing using Osiris. My question is what changes to the cam phasing people have found to be noticably beneficial? Any input here should help to speed up the tuning process.
As a side note, one person who I spoke with indicated that the stock cam phasing is pretty well optimized and that there would not be a noticable improvement by adjusting the cam phasing, but I don't know how much he actually played with this. Maybe someone who has spent a good amount of time playing with the cam phasing can chime in on this.

What kind of safety mechanism do you have in place if your meth tank runs dry? On mine, if the tank runs dry or a line gets clogged, the F-CON will automatically revert back to the base map. I also have it configured to turn off the boost controller, thereby reverting to spring pressure (about 6 or 7 psi I think) if this happens. That way, I can run higher boost when I have the meth system turned on, but the boost will automatically drop if an issue with the meth flow pops up.

Does one need to cut/splice wires when installing the 16 pin in "blue box" HKS Knock Amp?
Out wires...Grd. (2 G wires), CMP sen. (Y/B wire), CKP sen. (Y wire).... + Knk sen. (W wire)

I have an idea. Come by the shop, with your harness, Knock Amp, and FCON in hand and I will walk you through all the connections. Just call first. There are many wires not used. SGP wired up your FCON so I am sure it's messy. I have a huge folder of handwritten notes with wiring diagrams. HKS doesn't provide a whole lot of instructions for their Pro Tuners, so we have to figure some of it out on our own.

sounds like a date
Good idea but first I want to trace all the wires. + how will you be able to break free from your friend the dyno?

I know I already asked the question pertaining to the benefits of playing with the cam phasing, but the ablility to adjust cam phasing seems to be one of the significant features of the Haltech over the F-CON discussed herein. So, if it is a significant feature, I'm assuming that there are benefits to be had. Has anyone seen any benefits? If not, I think that particular feature is practically worthless. I would like to see a discussion of this from those that have played with cam phasing.
As I noted, one person that I trust has indicted that the stock phasing is optimum, but it is in my nature to continue to ask the question and ask for second opinions.
