Got a keydiver chip on my 1G ECU and it has a bunch of features:

7800 RPM Rev Limit
Stock 1G 5 speed 37 PSI AFPR
Knocksum Gauge
Rescaled MAS
450cc Injectors/Stock Deadtime
2G MAS "609"
No Airflow Cap
Rescaled Fueltrims
10.5:1 WOT A/F
Octane Reset
Enhanced Closed-Loop MAPS
Shift CE Light at 7000 RPM
800 RPM Idle
2x HZ for Logging Karman to 3212 HZ
FED/AWD
PK Code

I want to tune my idle to keep up with the 264 regrinds that are in it, and maybe for the HKS 264/272 cams I have stockpiled.
My WOT AFR is less than ideal and was only designed to keep the motor alive before I could afford some tuning devices.

I want to purchase this:
MTX-L: MTX Series Digital Air/Fuel Ratio Gauge Kit (ALL-IN-ONE) Now Shipping! - P/N: 3844 - #3844


Should I jump into Link V3 Full Edition or grab another SAFCII (sold it because money was needed for a clutch kit)???

Right now the car runs fine, idle is a bunch rich and piles up HC's in the cat if run long enough and it pulls great but I have no way of knowing RICH/LEAN. My E-testing on the rollers (run by me) proved the factory 02 was working very well, but WOT is what I am concerned about because my power drops off substantially at that point compared to 3/4 throttle and boosting (an aside not worth going into yet, I agree).

I am running a Palm IIIc and palm logger software but have a Laptop DELL Latitude D810 running Windows XP Professional, so plenty fast enough for Link datalogging.

Will this be a hair pulling experience to mimic almost all functions of the keydiver chip, is Link setup for most of that?

Also I want to install my Cyclone manifold setup (it is painted and ready to rock), can link incorporate this with little hassle? Am I tapping into an ECU pin, if so which one?

I will step up the injector sizing (Mitsu 510 or 560's good?) to match up to roughly 15-18 PSI, and install my Aeromotive AFPR and Walbro to match this.

I know I could get away with just the SAFCII but does that do things with timing I have to worry about? Or is that only because of really large injectors?

Can I retain full EGR function with link? Use EGR output to trigger the Cyclone when it goes on?

Motor is a stock 6 bolt 4g63 minus 264 regrind cams, 14b ported 02 turbo, 2.5" exhaust, all emissions working and hooked up.

Get rid of the keydriver and safc stuff, there's no reason for anyone to be using those tuning tools anymore with the price of v3 lite being so cheap. Even the lite version has a ton of features, but I think for your intake control you might have to use the full v3.

Your car will run 100% better with link even at the same boost levels once you get the tune dialed in. Also, I'm using a simple LC-1 wideband setup without a gauge which costed like $130 instead of a full gauge setup so that can save you some money as well.

I love ecmlink, it's awesome, you won't regret getting it!

Hi Tim.

You could use v3 full version of link for the cyclone activation with the FPR output, http://www.ecmtuning.com/wiki/nitrouscontroldetails

V3 lite and Full compare : http://www.ecmtuning.com/wiki/prodcompare?s=v3lite
With the full version you can tune the boost by gear, nice feature for a FWD !
Also speed density !

The MTX-L is a good WB, friendly with link without the bad read like the AEM ...

I think 560cc ( global -18% ) injector is a good match for the 14B, also the deadtime of this injectors is 0 like the stock 450cc. Easy to tune ...
Which gas, 91 or 94 ?

We have 87, 89, 91 (0 ethanol) and select 94 (0 Ethanol) Octane pumps here.
I run minimum 91 but mostly 94 when I fill up.

If I can keep the FPR solenoid and use another input, that would be great.

On a side topic I have always wanted to incorporate EGR into the Cyclone manifold - twice the benefit.

So, what input could I use if not the FPR solenoid driver? EGR solenoid (Federal/California dependant?)? other .... ?

If you want keep the FPR solenoid for hot start enrichment, v3 full has this feature : The FPR solenoid stock function is useless with ECMLink !
