How about some "electronics" or GReddy's turbo? I have already the cat-back on my GS and I'm very pleased. [/QUOTE

e-Manage (piggy-back fuel computer)


Our new e-Manage system is an inexpensive programmable fuel management system that allows you to properly tune your factory fuel system, without having to change the entire factory ECU system to an expensive "stand-alone" unit. The e-Manage system is a universal "piggy-back" type unit, which taps into most factory ECU wiring and it still utilizes the existing sensors. This unit only works on motors up to 6 cyl. Basic functions will allow the user to slightly alter factory injector duty-cycle(± 20% at 5 preset RPM points), by intercepting and altering airflow or MAP sensor signals. Additional features that are built into the system, but are only accessible though the use of our PC-Windows based "e-Manage Support Tool" communication software are a 16x16 Airflow Adjustmemt Map, Larger Main Injector correction adjustment, Upgrade Air Flow Meter adjustment, Boost Limiter Cut, Anti-engine Stall, VTEC-fuel adjustment, Real-time Map Trace, Real-time Display, Real-time Communication, and basic Data-logging.

With the use of our "Optional Injector Harness" and the software, the unit has the ability to control an additional 16x16 Injector duty cycle Map and the Controls for adding up to 2 Addional Sub-injectors. If the "Optional Ignition Harrness" and the software is used the unit has the ability to control a 16x16 Ignition Timing Map. All of the above Maps can also be Map-traced in Real-time as well. If the factory range of Map or Airflow meter is surpassed, you can incorperate our "Optional GReddy Pressure Sensor and Pressue Harness" to set larger scales of ajustment.

Also, if i were to do a supercharger on a GS 300 or IS 300 this is the unit i would use for my fuel system..

 

Charles,

As we spoke on the phone the other day, E-Manage system doesn't work with 8 cylinder so it is out of my question....

 

I am sorry to say that the unit only will work on motors up to 6 cyl.

 

So Charles,

What do I need in conjuction with this E-manage system to get some more ponies from my GS3?

 

Neo,

There are optional pressure sensor, ignition harness, and injector harness. Depends on "what" you want to tune your car. If you are only looking for fuel/air, then all you need is the main console. But if you have turbo application, you can take the advantage of those optional equipments.

E-manage is very good for BPU. If I had a 6 cylinder, I would do this upgrade no doubt.

 

RA,

Performance-wise, my car is stock. I've either done, or is in the queue with Steve for all the handling and body mods I currently want.

Now I am starting to look at power. I am actually more interested in torque than HP, although HP gains is also a must. I really don't race the car (street or track and have no plans to) but like to be able to accelerate from stop. Therefore, I don't like solutions that reduces low-end power. I probably should start another thread about this but since the conversation is already started ...

Where do you think I should start? I've searched and read. I just want to be able to plan/stagger an upgrade path. I know I should have gotten a 400 but that was not an option at the time of purchase. I am not really looking at getting to 500hp or anything like that. Going to 300+ should actually be OK.

Thanks.

 

Neo,

I think everyone would tell you to do the TC mod first because it's the best gain for the buck. That is true. However, if you are planning to do forced induction, I would suggest you to do TC toward the end because you would need a different stall speed than NA. Despite the fact that PI does offer a free chaning your stall speed, it's such a hassle to remove the TC once again, time and money wise.

Personally, this is what I will do.
(1)suspension
(2)rims/tyres, 10" at rear
(3)forced induction (turbo or sc) at the same time, you may need to upgrade your transmission including valve body, tc, etc.
(4)brake
(5)appearance stuffs (bodykit, wing, etc)

As you can see step (3) involves a lot of sub-steps which occur in the same time period. You can't just do SC and not upgrade your tranmission. But you don't want to spend lots of money to upgrade your tranmission first without knowing what performance you will get from the forced induction. You may not need upgrading the valve body if it's so minor.

You shouldn't worry about the ECU since wherever you will get your forced induction will provide either piggy back or entire ECU. I haven't seen anyone utilize stock ECU with forced induction.

If you are really into ECU, there are plenty of companys that offer ECU upgrade, APEX, HKS, GReddy, Blitz, TOM'S. Check with them to see if they have anything for your application. I know TOM'S will soon release their 2nd version of ECU for Aristo....

Set up a target range, hp and torque wise, talk to those tranmission specialists (PI, Level 10) and see what they suggest and stick with it.

It's a very brief introduction. Of course there are a lot more for it but it's 11:43 in LA and I'm hungry so I will stop here.

Happy modifying.

 

i must point out one more thing. There are no ECU upgrades for the GS line or the IS line for that matter. There are only piggy back systems, so if a company tells you that they have a full ECU upgrade ask a lot of questions. I have spoke to many of Toyota USA Techs, (not tech at dealerships) and they know for a fact that no one has come close to cracking the stock ECU.

 

I don't understand, why TOYOTA makes its ECU so hard to crack. Didn't TOYOTA use to provide some resource to G-Force (not sure if the name is right)?

 

You are most likely thinking of G-Force. but no the did not. They are now known as Tech-tom. It took them almost two years to crack that ECU. That is why the unit is ove $1900.

 

I guess we will have to wait til V8 is more popular in Japan. By that time arrives, I will probably ditch my GS already.

Charles,
Thanks for correcting the name of the company.

 

I also am trying to find some thing i can do to get more power out of the 8 cyl. I for one will keep trying. However, i will only use products that for 100% work.

 

Thanks for the overview. I will dig around some more to figure out what I will need and how much $$ I will need to budget.
