I ahve decided it is time for me to buy a new engine managment systme as the stock one is not perfect in its design.
I have a series 4 n/a.
I want the new ecu to "drop in" with out a lot of trouble.
I want the MAF gone. I want to have at least two settings, one for everyday street driveing with strong low end torque, and a setting for racing with power and ***** to the wall performance.
I want it to have control over everyting that makes power or fuel economy. I want it to be adaptable. preferably with PC interface.
I am willing to add some new sensors and such to get this, but I want an easy to setup system. I don't want to ahve to rrun through catalogs and web sites to find something compatable. I want a ready to fly kit. that jsut needs fine tuning for my setup.
And as always price is a consideration.
Does this exsist?

 

there is nothing that plugs into an s4 car. any standalone is gonna mean a rewire of the engine. the only drop in thing would be the hks vpc, it will get rid of the afm

Some day it will.

Since you are using your mojo to wish for the ultimate ECU, be sure to add a self-tuning closed-loop function which works fast enough to function during performance driving.

there isn't any kind of harness that adapts the stock wiring to like a haltech?
What you are telling me is that No matter what I am going to have to rewire my whole engine...
if that is true then that sux.
Then can anyone recomend an ECU where I can store maps and select them on the go, and get rid of the MAF. If I ahve no choice I will get what I can. what is the closest I can get to the above description?

 

k2rd thought about making a plug in adaptor for the s4 (to go from the haltech to the stock harness) but the harnesses are usually to bad to use.
any after market ecu will get rid of the maf. also i have noe idea why you would want more than one map, remember power is related to efficency

Ive got one that can do all that, plus it can make ice cream on the fly. Email me if you need any ice cream maps, ive got a pretty good one for chocolate chip.

 

double post.

 

The Wolf3D 4.0 uses memory cartridges like Nintendo. The EMS can store one map internally, and another map in the cartridge. The cartridge map can be loaded into the ECU within seconds with the hand controller, while the laptop stays safe at home. You can carry around extra cartridges if you like, they are rewritable like computer disks, and you can download new maps to the cartridges from your PC or laptop within seconds.

The new Haltech E11 is supposedly able to carry two maps in its memory. This is more limiting than the Wolf, but then again you don't have to mess with cartridges.

The advantage of this is difficult to understand for those non-Wolf owners who have never had such an excellent function available. I'm sure that the Haltech Jihad will soon praise the advantages of this function as soon as the E11 gets into enough grubby hands.

Yes, power is related to efficiency, but power can also be related to unreliability, poor driveability, poor gas mileage, and failing emissions tests. An EMS with 3D boost control can even have different maps for different driving conditions (wet track, dry track, autocross, street, etc.).

 

thanks evil,
That is what I needed to hear.
Power is only related to volumetric efficiency. not fuel efficiency.
I need a fuel efficient map for low RPM torque and fuel economy. then I want another map for all out performance.
Do you know if the wolf will let me have precice control over ignition. I was thinking of getting an ignition controler for turbos. the one that will let you set timing in 500 RPM incriments +/- 15 deg.
I also couldn't find any pricing or even where to get the thing on the web site. the only "dealer" page had something about linux stuff I didn't read

 

Actually, BSFC is one of the leading methods of evaluating an engine's performance, and it is directly related to fuel efficiency. I guess it depends on how you look at it, but IMO it is better to look at things with several different perspectives.

I think what j9fd3s was getting at was that you could tune the lower load bands more for economy and the higher bands more for performance. This would give you an all-around street map. However, two separate maps would allow for more dedication to economy or performance. BTW, I don't think that you can tune for both torque and economy at the same time, but I wish you well on your quest.

The Wolf 3D 4.0 has ignition map points every 125 rpm, and the range is -11.25 to +78.75 degrees. The new 4.0 version software also lets you set 2-rotor split timing for different rpm bands, but I don't recall the resolution or maximum split allowed, although I know that it at least goes up to a 15 deg split.

I would just like to point out one of the downsides of the new Wolf3D 4.0 that the dealers may not mention. With all of the excellent features and improvements, the 4.0 version has absolutely no datalogging function, and it doesn't even have basic oxy logging like the previous 3.0 version. I think this was a very bad decision on the part of the designers, who seem to be on the "live" tuning kick for some reason. However, if you are the type of person who tunes to live data like EGT, an AFR gauge, and/or the live tuning software via laptop, then this doesn't matter a bit.

I'm sorry to say that the Wolf support in the US is awful, just like every other Australian EMS except for the very expensive Motec line. It appears as though the Australian EMS manufacturers are attempting to form better US relations, although IMO the support still isn't up to par as of yet.

my point was that on an na, your reformance map, and the fuel economy maps are gonna be the same, all you need to change is your shift point.

mike

 

How do you figure that the performance map and economy map will have the same ignition timing, acceleration enrichment, secondary injector staging, etc.?

 

because fuel economy, you want as much timing as you can get (same as performance), ok maybe you want less accelerator pump (my 20b map uses very little accelerator pump as is), and for economy you arent going to use the secondaries. look at a vx civic, they have it geared to go 60mph @1500rpms

thanks guys. Especially evil. No data logging is a downside. I think I may go with the wolf anyway but I am looking at the Tec 3. I found a guy that has one never put in because he wrecked the car. he only wants $2000 for the whole thing. any feed back? This is a pretty new system isn't it?

 

the tec prices are on their website, and yes the tec3 is about 6-9? months old
