Is there a reason why i dont see more RX7 owners use the TEC II and the TEC III?

Cost too much...
How many MoTeC's do you see?

... and not very many people want to deal with the 60-2 ignition wheel when every other EMS uses the stock crank angle sensor.

i've got one and i'm local, two other guys running them too, let me know if you wanna check it out

I doubt it's the wheel that scares anyone off when Electromotive claims superior ignition accuracy because of the wheel. That is actually a selling point.

I think its easier to bolt on that wheel (4 bolts) than it is to solder the connections to the existing crank angle sensor.

I think it's also the lack of support combined with the price.

Having a bolt-on ignition trigger system makes it easier, but Electromotive does not make bolt-on kits for all vehicles.

Else, the 60-2 trigger wheel needs to be precisionly installed.
If it's off by a little bit, it'll give you headaches.
On top of that, it needs to be protected, as I know of racers who have gotten road debris kicked up into the ignition trigger system causing problems and failure.

There is nothing wrong with the stock ignition system.
If you can't solder proficiently, then you shouldn't be messing with electronics in the first place.

Sure, you can't fault the superior trigger accuracy of the 60-2 Motronic ignition trigger system, but other systems using the stock ignition trigger systems are getting + / - 1 degree of accuracy.  Unless you're tuning for max power at the absolute edge of accuracy of ignition timing, I have yet to see proof of this "disadvantage" in ignition timing accuracy affect EMS performance.


Ray @ Shane Racing is an authorized dealer.
I'm sure if you pay his fees, he'd be more than willing to provide all the service anf support you will need.

With our engines, no one wants to take the remote chance of innaccurate ignition. I have heard and seen many examples of haltech users complaining of timing issues. Many of the cars at the track, hardcore rotary drag racers, have decided it was safer to run a distributor when asked.

When I say support is limited, it is. Support meaning forums, local guys running the same ECU, even on this list there is not enough volume to have a TECIII section.

I am in NYC, Shane Racing is very very far away. I cannot trailer my car there to get tuned. The closest place is Electromotive itself.

Now that Demetrious (Reactive Racing) is running a TECIII guys on the east coast will have one more option.

I'm biased towards aussie ecus myself but i'll give you my opinion.

You can't argue the fact that more teeth will give you more accurancy but lets not forget it's just as important what the ecu does with this signal since this is what it will use for both ignition and injection timing.

12 teeth on the crank (stock fd) or 24 teeth at cam speed,(no pun intended i'm still a piston guy at heart,LOL) FC setup, provides very good resolution.
I don't see a need to have to replace either trigger setup even in very high hp applications

Don't be fooled by marketing hype. I'm not saying the Tec3 is a bad ecu by any means, just that many companys will use what they can as selling points. There's pros and cons to every ecu.

RETed

Could you be more specific?
The only "complaint" I've hear of is the decel / accel play of the engine which will also haunt the TEC3 no matter what you do.

I haven't run into any problems with numerous Haltech customers I've installed and tuned, but all of them are street-tuned and not running the last 1% of ignition timing to get maximum power.

I've haven't personally scoped the Haltech ignition, but I've heard + / 1 1-degree as a conservative estimate on timing deviation.

I would tend to blame the install and tuning on ignition timing issues.

I really can't be more specific since I never experienced any of this myself. My timing on my e6k was fine, and the car ran excellent. BUT, in the tri state area when going to the local track events, you hear things from various tuners and hard core drag racers. I agree that it could be install issues but I was always curious why these tuners/racers would state these things. Again, my e6k ran perfect and I used the stock shielded wires to the cas.

I agree there are pros and cons on every ecu. I have seen some fast and reliable haltech cars, I have seen some fast and reliable wolf cars. Same goes for the PFC which I think everyone respects highly now, same goes for the microtech.

I have had many offline discussions with various tuners in different areas of the country and each has its own favorites. I've recently spoken to bmepfuel and tuning and is 100% confident and highly recommends the autronic.

I guess once people see any of the ecu's mentioned in "action" and the car running reliably and consistently, thats the real test.

These two quotes sum it all up.

Ted's right, with a price tag of roughly $2600 for the tec3, not many people are willing to fork that out, and if they were that would put you in the same price range of a Motec M4 at $2300 plus ignition or a Autronic SM2 at $2000 plus ignition.

Plus as EVIL stated, not many people want to be bothered with fabricating there own trigger wheels.

With so many ECU's at less then half of tec3 prices it's no surprise that you don't see many people using tec3. Besides price, they offer much better support, user friendly software, easier installion, and everythings included, no need to buy harness, ignition, and sensors seperately.
EX. Haltech, PFC, Wolf, Microtech.

This is true. It's because you feel confident that someone else you know has good results and there's local support for that particular ecu.

that's why you should always buy an ecu that offers local support and meets your budget. Remember to include installation and tuning into your budget. This is often overlooked.
