Engine Management. Place your votes.

Okie dokie guys.

In my very very near future lies a Targa Jza70 (as soon as someone can find me a Targa one) and as it sits I would like to see a modest 400hp or so. But we all know how that goes, you always want more and more and more; been there done that.

So what are you votes for engine/fuel management options for the 1J. I would always like to keep the possibility of swapping in a 2J open sometime down the road so if the 2J easily accepts it, all the more power to it.

I know some people use a Safc, Emanage, and few AEM users are around.
I have used and played with a Safc in my and buddie's Talon's (4g63T) and it is pretty easy to get the hang of.

Obviously the Emange is superior to the Safc and AEM superior to Emanage. I am not sure I will be pushing enough power or have enough knowledge to go full stand alone, so that sort of throws AEM out the window.

Basically if you could post what you use/prefer and why that would be great. I am just trying to get my parts list together so I can be prepared and maybe start picking up a few items.

Thanks alot for reading all this babbling on guys.


***EDIT*** While we are sort of on topic what do you prefer for a wideband??!?

Stinger looks to be the bomb. You should look into it

 

[BigTree]

Will do.

I am open to any and all opinions.

Thanks.

if you plan on running your 2j on the 1j electronic's,that should also make your choice a little easier.the aem seem's like the only real success story.i had a safc II on my 1j and had a hard time leaning it out down low with 550's,cam's,single.i ended up buying a power fc (not installed yet)to play with because it was p&p.you might want to look into what ems you can get support on in your area

 

[foreverpsycotic]

are you planning on throwing a 2j block under the 1j head, or just a full 2j swap? for my 2j na-t swap im thinking along the same lines minus the AEM. the SAFC is cheaper and easier to learn, but the emanage has more options, and can be used to tune better, but harder to do on your own.

 

[BigTree]

Oh ya. In my area there is NOTHING and NO ONE who professionally knows how to use any of these products. The very closest possible place would be a 20h drive or so each way to get there; Vancouver. That is if someone is trained down there.

So something that is a bit more user friendly is really helpful.

Go to the guys at RCTS ( http://www.monsterhorsepower.com/ )they can do the HKS V-Pro and already have Maps made up for it, it is also plug and play for the 1J Harness, They are located in Calgary, i know it's probably not any closer for you, i am sure they could offer you help over the phone. Plus they have a bunch a MAPS already made out for the 1J, i am sure they can tweak them for a 1.5J

I know someone with the Power FC on there car, they seem to be enjoying it allot, it's another p & p.

emanage.. 400whp isn't that big of a goal and it will work perfectly.. if anything more then 500whp i'd start looking into a standalone..

 

[foreverpsycotic]

i just checked out the emanage more in detail, it seems to be a very powerfull piggyback. this seems to be a more viable option for both you and me.

 

[BigTree]

Tissimo, is there any specific reason you would choose not to run the Emange in excess of 500whp?


In all of your general opinions, is the Power FC or Emanage a better system?

Thanks so much guys. Awesome

 

[ranger2339]

I will be running a Blitz ECU,emanage,550ccinj and a TO4R etc...Going for 450-500whp.

You can do 400 with an SAFC.

However, I'd still vote Emanage, just for the timing control option.

 

[becauseican]

For simplicity's sake for 400hp, I would say that a tuned Stock ecu with and S-afc and a boost cut controler is the best way for 400 hp. I currently run a Mines ECU and a Emanage. Its good but it takes alot more to tune it correctly and the install is allot more involved when using all the options like MAP sensor, injector harness and timing control, and you need a laptop also or a $400 E01 Boost controller. 1jz's respond very well to the S-AFC, thats my vote.

Standalones are great if you want to spend a ton of time to get it to run perfect, and you still end up with flats spots and or bad fuel economy. The cost is allot more to with the cost of the unit and tuning/ dyno time. I just dont have the time to be constantly tinkering with a standalone to work out the bugs. I love just hopping into my car every morning turning the key and it starts and drives perfect every time, you will never get the same drivability and fuel milage with a standalone. For 400 hp it would be a little over kill, but for 500hp+ I think a standalone is the only way to go, piggybacks like the S-AFC and Emanage are just bandaid solutions past that. At those power levels the its a very fine line with high boost and tuning, and piggy backs just dont have the resolution to control it accuratly. Once you are at higher power levels you are modifying the stock ecu's signal so much with a piggy back trying to compensate and no real way to monitor injector duty cycle, ignition timing.

[BigTree]

Very very helpful information. Thank you very much.

So what do we have for good stand-alone solutions? AEM...?

P&P is best is possible

 

[becauseican]

AEM is great but more money. A friend of mine is making a P&P setup for a Microtech. I might go this route also. Where in B.C are you?, I am in Langley/ Vancouver.

Because over 550cc injectors I dont trust what the stock ecu is doing with timing..

Powerfc is better then Emanage cause it is a full standalone where as emanage is a piggy back..

We looked into the Microtech before we went with the EMS Stinger. We actually ordered a Microtech from a friend that is a dealer for them and after about 2 months it still was not shipped, we gave up and that's when we came across the EMS units. The Microtech has to be special ordered with all the settings for the specific engine you will be installing it on. So if you buy the Microtech for a 1jz, and later you want to use it on a different engine, you have to ship it back to Microtech for changes to be made. We learned that because we were origionally going to use it on a 4age, but it took so long that we changed plans and wanted to use in on a 7m or 1jz instead, and we were not told about the special setup until we asked. The Stinger will work with any type of engine with any number of cylinders and any stock temp sensors and any type of ignition pickup and fuel injectors.

I am not saying the Microtech is a bad unit at all, because I'm sure it is not. I'm not even saying to buy the Stinger instead if you get a great deal on a Microtech, but if you buy one used or you can't special order it for your application, you may run into some issues.

Aaron - are you guys going to install a Stinger in Bruce's car?

 

[bigaaron]

Aaron - are you guys going to install a Stinger in Bruce's car?

Yes, and I am going to make the harness myself.



I finally got the wideband and air temp sensors installed on my 7m with Stinger last night, and right now it's idling at 10 deg timing and 14.6:1 af. I'm going to try to get it over to the dyno tomorrow.

 

[The Reaper]

d you have a Link to info and facts about the stinger? since it can be easily switched from engine to engine i might get one for the 1J so i can later use it on my 2J when i make the switch
