Haltech or Wolf???
 

I want to know some info about both of these ECUs...
I live in Cali and want to know if I install either one of these setups in my FC will I be able to pass emissions here???

No chance with the Wolf tunability is very poor. You may be able to with the Haltech depending on how well the tuner knows the system and whether they are able to tune it well enough to pass providing you have all the other required emission things on your car.

I have a Wolf 3D running my car with 4 1600 cc injectors, and my car is very driveable. If tunability was poor then my car would drive like crap. The tuning works the same as every other system.

All you really need to do to pass emmissions is to lean everything out and maybe bump up the timing a bit. If you throw an air pump on and run it directly to a converter you should be able to pass if the car is leaned out enough. Just make sure that they stay out of boost if they put it on a dyno.

The Electromotive TEC II can be used to pass emmissions as well. It's supposedly CARB legal, while the Wolf and Haltech aren't. George Samuels's 20B convertible passed MD emmissions with a TEC I...I think. Gordon Monsen's car passed emmissions with a Halteck E6K.

the tuning doesn't work the same as every other system, if it did why do you think some ecu's are loads cheaper than the others?

tuning resolution.

Shane - retreating to his haltech bomb shelter

The resolution(ignition and fuel every 500 RPM) is about the same except for the load sensing(only 8 points). My TEC II only has 8 load points, but it's also a good system. One feature I don't like is that the Wolf uses the same settings for >8K RPM as it does for 8K RPM. Luckily my rev limiter is set at 8500. So that's not really an issue.

I've looked inside of both the Wolf and Haltech and my cellular phone looks like it has more work put into it.:rolleyes: They're both very similar in price. The Wolf 3D is only about $100-200 cheaper here in the U.S.

If you are thinking about getting a Wolf it would probably pay to wait until V4 comes out. It is mapable every 125rpm, 32 load points, 16000rpm (i think) + much more accurate than V3.1.

I agree that the Haltech is much better than the old Wolf, but the new one is suppose to be up in the same bunch as the MoTeC, Autronic & Haltech. We shall see.

Resolution is RPM points AND Load points or RPM x Load points

ie: Haltech E6K (32 load points per 500rpm) has 704 user definable mapping points without taking into account the interpolation

Ok, I'll admit that the resolution is better. I had always thought it was 16 loads points. The bar thing is a little weird to me. I think that the Haltech is a good system(many fast cars using it), but I have had no problems with the Wolf. I had actually bought it for no reason, but it helped me out when my TEC II freaked out on me.

The Wolf3D has a control unit that mounts in the car right???
So when is Wolf is going to come out with the V4 model???
Sounds like that ECU is going to be more tunable than the Haltech...
That ECU sounds like it it going to be better than the Haltech....
WHere can I read some info on it????

Yes, the Wolf 3D has a control unit that you can watch while you're driving, etc. The new version is supposed to be out very soon. You could try asking BOOSTD7 about it, or check out the Wolf Forum: http://www.wolfems.com/wolfvb/index.php .

Thats what Ill be getting;)

Every 125 RPM? That sounds like 4x as much work to tune. When is it coming out????

ECU vs ECU
 

Aren't these threads great :D

Hehehe, my thoughts exactly. Actually, it's worse than that, because the load would also be 4x more work, so in all that would be 16x more work to tune (128 vs 2048). Oh well, it sounds like it will be pretty good, anyway.

BTW, the tunability of the Wolf 3D 3.0 is just fine as long as you don't have a high-rpm ported engine, in which case the E6K would be a better choice for a budget ECU. If the tunability were bad, then my friend's Wolf 3D NA stock-block Sport wouldn't be dead even with my TII in the straights. Oh yeah, and he gets better gas mileage, too. :)

I don't know about tuning it, maybe they have some kind of algorithm which works out a point inbetween if you only want to tune to a certain accuracy. This is all what I have been told by a reputable source, but until I actually see it with my own eyes there is always a bit of doubt.

The date that I have been told that my workshop is getting it is 12 Nov. I am going to give them a call next Friday and ask whether that is still on. I hope so, because I am getting it put in my car. I will let everyone know what I find out next week.

I don't take my motor past 8500. So the Wolf 3D works fine for me. Tuning my car was pretty simple. waynespeed loaded his map onto my ECU and off we went to tune on the street.:D

I like the Wolf 3D ALOT, and if a newer version comes out I would probably get it for another car.

is it true you can send of the v 3.1 to upgrade to v.4 when it comes out?

Do you still have to get your CAS modified to use the Wolf V4?? Like with the Wolf 3D?
Does it run the factory mazda coils?
Can it control the split trailing spark?
If so i may consider buying one to see how it really is.
Although i am very biased when it comes to ECU's becasue i have tried a few.

If that's true then I'll be doing it. Everything about V4 has been hush-hush. Maybe Ryan can tell us something???

The Wolf 3D runs the factory coils. So I will assume V4 will. The 3D controls the trailing. SO V4 should also do that.

What does CAS modified mean?

moderator please delete these two posts.thanks.

For the Wolf 3d to work on the 93+rx7 engines, the 13b-rew,
the CAS=crank angle sensor must be modified to accept the signal

You also have to mod a 2nd gen CAS.
