1g-gte Piggy Back Options

[Z2TT]

Hello.

First and most important information on my car.

1989 GZ20 Soarer Twin Turbo
1G-GTE Gen 3
Front Mount Intercooler
2.5" Exhuast
Pod Filter

Before I begin boosting up the turbo's I am thinking of getting a piggy back like an Apexi SAFC Installed and Tuned. I have searched many threads and some people say its not worth it, while others say that the 1g-gte does run a bit rich so a SAFC would help. Does anybody have an SAFC or other fuel/controller on their 1g-gte and does it give any performance gains? Also would SAFC be the best option? or is there better units like HKS F-Con, or Greddy E-manage I think its called.

Thanks if anybody can help.
Boris.

it's all quite the same really... just that the tuning points are different.. some have points every 500 rpms, some have points every 200 or 100 rpms.. E-manage is my preference because you can map ignition timing as well, and plug it into a laptop for full map view.. and it's value for money in terms of tuning power compared to the S-AFC..

but yea if you're going to go get a bigger turbo in future, a full aftermarket ECU is a good investment now, as the piggyback can only handle bigger injectors, but not boost mapping unless you're thinking S-AFC + AVC-R..?

Any control is better than no control.
SAFC is a cheap and effective way to control fueling at higher than stock boost pressures.

That said it is not as good as a stand alone engine management system. Emanage is the best as when you buy the ultimate you get ignition timing as stated above.

The Xede Piggy back is what I will be using on my 1G-GTE. I prefer it over any of the other options as it does fuel, timing and boost and also supports map switching at the flick of a switch. Since I have no intention of chasing massive power or fitting a huge single turbo its the perfect option for me.

If you have plans for extensive modifications spend the little extra and fit a complete stand alone ECU, Microtech due a very cost effective unit for the 1G or if you want boost control as well an Autronic SMC without Autotune is not much more than a Microtech.

I reckon the Jaycar Digitial Fuel Adjuster is better (more load points) than the SAFC, but not as shiney and you have to put it together yourself. I use 1 on my daily driver 4AGZE MR2 that I fitted a bigger airflow meter to and it's fantastic. Cost heaps less than the SAFC aswell

Thanks for the replies, I am not really after heaps of power, I just want to get more out of my engine, It's a street car. I got a few questions now.

1. I looked to see the price of the greddy e-manage, the following products I see are
- Greddy E-manage "ultimate" Complete universal harness $204
- Greddy E-manage "ultimate" Supplement Harness $72.95
- Greddy E-manage "ultimate" with software $992.95

I see prices between these products vary much, what is the difference?

2. Say for an example, if I get my Emanage/SAFC/etc tuned, then I increase the boost, would it be required to get it tuned again? otherwise will i have problems?

3. If I upgrade the turbo's to hiflow ct12's, would I need to get the afc retuned?

4. Has anyone here had an afc installed to their 1g-gte, how much more power did you get? also what PSI you were running could be helpful. What gains should I expect to get at stock boost? just wondering.

Thanks,
Boris.

i run an emanage on my 1ggte and yes, everytime u change something in the setup u need to retune it accordingly
worth it though once u get the setup right

http://www.mohdparts.com/ for shit loads better prices

I have an EMU aswell (I still use the Jaycar DFA to correct the output from the airflow meter) and reckon that they are much better in priciple than most other interceptors because they modify the injector signal to acheive desired air/fuel ratios. They also have dual maps and a resonably capable Auto Tune feature (you'll need a propper air/fuel ratio meter. I use an Innovate 1).
Goto Mohdparts.com and download the software for a look and a play. Also download the manuals (combine they make up the emananage support system that some people have the nerve to try and make you pay for )
A good thing in my book

[Z2TT]

Karma Supra how much more kw did you gain when you got your E-manage tuned?
Do you know the difference between the models I have listed?

Thanks,
Boris.

This is a wiring harness


- Greddy E-manage "ultimate" Supplement Harness $72.95

This is also a wiring harness


- Greddy E-manage "ultimate" with software $992.95

This is the box that does stuff, and also the software to let you modify it using a PC.

So I would need to pay about $1000 for the e-manage because i would need the wiring etc?

Would it be better to just get a SAFC thats $500 or $600?

Thanks.
Boris.

ebay safc, $250 ish for a second gen

Boris,

Why would you spend half the money to only do 1/3 of the job ? An SAFC can only trim fuel and is very limited in its ability. What about your boost and ignition timing ?

If your looking at an emanage then you should seriously consider an Xede.

Its not often I sayit but Yeah the 1G suitable Microtech is very hard to pass up on and is the "best" value for dollar option if you already have a stand alone electronic boost controller.
