Question Battle of the ECU's. Haltec vs TEC-2

Leeeeeeet's get reaaaaady to ruuuuuuuuuuuumble!

Seriously though, how do these two ECU's stack up against each other?

CPU speed? Sensor inputs and outputs, durability, cost, programmability and flexibility, etc.

Also, manufacturer's websites would be most appreciated, as well as reference documentation, if any.

You want the E6K and it uses Abobe so if you don't have it download it to read the specs.

Honestly, I don't know of anyone (that has posted at least, lurkers speak up) that could actually compare and contrast these in fine detail. Trey could state the features of the E6K, answer some questions, etc.

Shiv (and other members of the Vishnu forum, they're getting to be some pretty smart dudes) could talk about the TECII.

But I know one feature the E6K has that the TECII doesn't-- fully sequential ignition.

I Like the fact that you can hide the Haltec.
The TEC-II you have ignition wires everywhere

Just my .02

Does the Haltec use the stock ignition? I'm looking for a cheap and fairly easy to use plugin programmable ECU that will allow you to remap the A/F and Ignition maps using the stock injectors/ignition/sensors (sans the O2)? Is this asking for too much?

Heh, Try www.perfectpower.com They have a variety of products including complete EFI systems. Cheapest things on the market, but resonably featured. I haven't looked through thier entire line lately, but if the Mic3 is too much, I think they had a simple fuel/timing computer too. It will be able to use the stock coils no problem. On my wagon I am using the coil pack off of a SHO, and the motor origionaly used a distributer.

Shawn,

The E6K can use the stock ignition coil pack. It can be upgraded to its own high-power ignition. This the same as the TECII, except that Vishnu Performance does not sell the TECII without the coils.

The E6K can also use the stock crank pulley / cam angle sensor in addition to several other means of timing, including a multi-toothed wheel like the TECII uses.

With stock ignition and stock CAS, Trey is estimating that the E6K would run about $1200.

Don't forget that the TEC has a programmable knock sensor, continuous high res. crank position aquisition, user-definable MAP/RPM breakpoints (not fixed at every 500rpm) and Windows interface.

Colin,
It sounds like the E6K would be a more cost effective way to go at least as far as N/A power is concerned. I would think that the stock ignition and injectors would be adequate at least for most N/A modifications. Any comments?

Nate,
How easy was it to install? Any splicing involved. How difficult is it to get up and running?

I have an E6K on my Mitsu. It is using the stock camshaft position sensor, stock coil pack, stock power transistor, and even most of the stock wiring harness. The only things that needed to be added were an air temp sensor and a 3-bar MAP sensor (for turbo cars). The Haltech manual even has a section for Subarus. While both can accomplish the goal, I think the Haltech is a more elegant solution.

We had teams from several schools at Penn State this past weekend and there were a few common threads among all of the tuners when their cars were on the dyno.

Most of them swore AT the Haltech unit. They are VERY slow to load when you make changes and are only marginally user friendly.

Everyone that had used the Motec had mostly good things to say about it. The only real downside seemed to be the price of admission.

I have used the TEC-II for the past 3 years and can say that once you are familiar with the software it is not hard to work with at all. HOWEVER, I have not seen the new Windoze version of the software yet. I can't imagine that it is that much different than the old stuff, probably just looks better on the screen.

I also looked into the Autronic for a good while and am still considering it for my rally car (323GTX.) I have seen them, but have not used them myself. Everyone that I know that uses them has good things to say about them.

I would like to see one of the Fel-Pro units but have not as yet.

The SDS setup got mixed reviews from people that I have talked to that used it. Some liked the fact that you don't need a laptop to program it, but most people said that they really wished that they had gone with something with a few more adjustments and parameters. I guess you get what you pay for...

Actually, it's even easier to use since you can keep datalogs in the background while you are filling in VE/ignition/air-fuel tables. It also has a lot more intake temp dependant fuel/ignition trims. It's really better in every way. However, unlike the older DOS program, you have to press ALT plus the number key to select parameters in the engine monitor screen. A little difficult to do when driving. In that way, I lik the honest black and white simplicity of the DOS program. But functionality-wise, WinTEC kicks butt. WinTEC v. II is going to have autocalibration as well (no more filling in VE tables).

I agree...the new TEC software is great to use, though the older, slightly more simplistic version was straightforward, once you got the hang of it.

Bottom line is that the ecu is only as good as the tuner behind it. I think all in all, the Motec offers the most adjustment range (one of the Motec systems is adjustable tlike every 25 ROM or something!)..at leastthis was the case a few years back when I was looking into the systems for my ZX. At the time, Accel DFI was widely coming into use, but I don't believe it was fuel/ignition. On the ZX (which used a distributor), this was important to me...on the Subaru, which essentially uses a similar coil pack design as the TEC, which itself is derived from a GM unit developed way back when (and is spot on reliable BTW), I don't know how important having the ignition functions are. Does Electromotive now offer a fuel-only system?

I have played around with teh Haltech a few times, and found it also easy to use. I suspect that Trey is going with it for two reasons: 1 to seperate himself from others (diversity is always good), and sort of give him a "signature mod", and 2, because of his background. For those who don't know, Trey is among the most knowledgeable rptary guys in thr country, bar none. For one reason or another, rotary guys LOVE the Haltech....many of the fast USA and uerto Rico cars use it. So, he is experienced with what it can and can't do, and I suspect he knows how to fully maniplate the system (ina good way), to get the mst out of what it offers.

If I were to do it again, I would either go TEC, or the LINK, which while not widely used here, is loved overseas from what I can tell. True, it is a bit more limited than the TEC, but it is self contained, which is a plus (though carrying a laptop is no big deal for me, as I usually have one with me anyway for work).

Some of it is Miata-specific, but not much.
