hi my name is tom just wondering i have a 97 nissan stagea the motor has a upmount to4 turbo with 38ml external wastgate and need a new computer to run higher boost. i heard the power fc cant be plug in if the car is auto as u all know most stagea's are all autos. so i was wondering if any one know what i can do

'thanks tom

If your willing to spend $1k or so a Greddy E-manage Ultimate can do the job. You need to know a little about which harnesses to buy, so ask a dealer in your area, or have a read here:

:woot: cheers ;)

PS; many of the guys on here have had Stageas for a couple of years. There is very little that we haven’t previously discussed and resolved. Please try a search first, as the chances are, no matter what you want to know, it’s been covered.

thanks mate a guy said that could use a SAFC II for it and just piggy back but i dont know what he means about piggy back it

“Piggy back” means you use the SAFC (DFA, SITC or equivalent) to “bend” the signals going from the various sensors to the standard ECU. An example would be using the SAFC (or DFA) to ”tune” the AF ratios via changing the AFM voltages that the ECU sees.

The Jaycar DFA is very similar to the Apexi SAFC, so the DFA thread is 99% applicable to the SAFC. Do a search on SAFC’s if you need further info.

:P cheers :D

Yeah piggyback means that they intercept information going to the stock ecu and trick the stock ecu into thinking something is not happeneing, when it is.

I had a SAFC on my old R33 and it did good for just tuning the AFR's, but didnt do anything for ignition, which you can buy a jarcar kit for.

I guess with a true standalone replacement then you have the power to fiddle with all the various parts of your car which it controls. When I say you, I mean your tuner :no:

hey ska thanks for that if i intsall that safc will let me run higher boost and will it tell me if the motor was going to blow due to higher boost or dont i have to worry about that.

one more thing about the ingition does it make a big difference and how and when u say afr does that air flow something

sorry i dont know to much yet

thanks for all ur help

OK AFR = Air Fuel Ratio (http://en.wikipedia.org/wiki/Air-fuel_ratio)

Well when you run higher boost, you obviously need more fuel, right.

But if you run too much boost you will blow your motor, wether you have enough fuel or not, you'll end up with a hole in your pistons or worse.......

So if you run high boost with a stock ECU (computer) it see's the amount of air flow through the AFM (Air Flow Meter) and so when it gets to a certain point, it basically goes into R&R mode, (Rich & Retard) where it puts as much fuel in and retards the timing back to save the motor.

What something like a SAFC does is intercept the signal going from the AFM to the ECU and tricks the ECU into thinking there is less air flow then there actualy is.

It probably does a whole bunch more stuff, but that is about the limit of my knowledge :laugh:

Please anyone correct me if I am wrong, ie SK :O

good price!! but are they worth the extra bux over SAFC etc?

They are a big upgrade over SAFC or other basic Interceptors. See the E-man-Ult reads the AFM signal, but doesn't alter it. It splices into the Injector wiring, and leans/richens by changing Inj Pulse-width itself, instead of tricking the factory ECU. The factory ECU can't tell anythings odd, as RPM, AFM, TPS all line-up fine, so it just runs as normal (no fuel cuts, or too much ignition advance/retard).

The E-man-Ult does the same trick with your ignition timing. Its got most of the power of a wire-in standalone ECU, but keeps other factory ECU functions you need, like shift-logic on an auto for example.

And it doesn't need a hand-controller to program, it has a USB connection for your laptop yeehaaa!

Writings on the wall for tricky new vehicles and standalone systems, hence chipping late evo's etc being so popular, and when you wanna tune it yourself, an E-man-Ult for this sorta price is a lot of tuneability for not too much $$. Or so I think :laugh:

my haltech e11v2 works very well.talk to a guy named adam at JUST ENGINE MANAGMENT near liverpool,sydney.he did mine and is a wizz with all ecu issues.dont have his number off hand sorry!!

so, youve currently got an auto?

would LOVE info on gear shifts, quality thereof etc, current condition of the gearbox.

from all thr info Ive received, there isnt a full computer that operates the Nissan auto computer correctly (ie retard the timing, and control the shift points)..................................

I have yet to see an EManage work successfully on an auto Skyline/Stagea.

The first releases had problems with over heating ignitors and coils, leading to total ignition system failure.

The main problem is, because the EManage sits in between the ECU and the ignitors, it interferes with the ignition retard and cut on gearchanges. So you get harsh gear changes and the resulting premature wear on the bands and clutches.

The above is why I use an SITC, as per the following thread:
