best engine management system?
I have a 1985 GSL-SE 13b 6port. I just rebuilt it. custom medium street port and polished.. just ordered a S4 intake. about to order RP 60psi fuel pump and 4 720 injectors. thus i believe i will need a new ECU. i have been looking at getting a new ECU and engine wire harness. I really like the Haltech F10X. it's not a track only car. it's a daily driver and weekend autoX. so any suggestions or thoughts. what syatems are you using and what do and don't you like about it?

Pro's- Will do anything you want it to do, Spark Cut Rev, 20x20 Fuel/Spark Map, Will do spilt spark (Trailing/Leading) Large support group for hardware, Only will run 2 Rotor engines
Con's- Not a huge support group for Software for the Rotary, Lots of hands on tweeking of the board because it will run so many different ways
PowerFC
Pro's- Plug and Play for the FD3s, Small wiring to make it work with FC3s. SUPER large support groups, even for Rotarys. Has built in Boost Controller, Controls Twin Turbos, Commander to see engine monitoring without Computer, can change settings with the commander as well
Con's- Fuel Cut Rev Limit and Over Boost, Have to have a Datalogit to connect to a computer, To run more then 4 injectors you must use a Injector Driver,
There you go

IMHO, you should find someone local to you who has tuned rotaries before and managed to not blow stuff up. Ask what they've used and what they recommend and what they would be willing to help you with.
There are probably quite a few systems that could work... ECU's are complicated and IMHO it's better to find something that will work correctly for your project the first time rather than the cheapest or most capable or newest thing out there. Luckily you're non-turbocharged so there is more room for error, but it is very easy to make a mistake when learning something new. Unfortunately a standalone ECU gives you the ability to cause a lot of damage if you make mistakes.

I got a haltech because the person that tunes my car knows them and swears by them. Also using the long flying lead the car has a full new harness. I'd tell you to go haltech but if no one around you knows how to tune them that doesn't make much sense.

thank you for the help. there is a race shop here in tulsa, ok, that recomends haltech. the only thing i don't like is the that they mostly tune hondas and toyotas. and NO work on RX7s. i have done some research and really like what haltech has to offer but i have never worked on an ecu. there is only 1 rotary shop in town now and i don't trust the guy seeing as i know more about rotarys than he does (we had a very long disscusion and he was amazed at what i know) in no way do i claim to be an expert. i am thinking about just getting the system and learning by trial and error. do you think that would be a huge mistake or just a really good way to learn? and as a note i don't make much money but i save to do the things i want.

i would also be curious to the answer of learning, i know there are seminars and such.
wouldnt we just need to learn the basics and apply it to different ECUs?

If you're interested in the Haltech line I'd highly recommend you look at the newer Platinum ECUs. Better in terms of ease of use, reliability, and function. The Platinum Sprint RE is the new entry level ECU. Other than being limited to high impedance (>12 ohm) injectors, this ECU will do everything the F10X will AND has four ignition outputs. This will allow you to ditch your dizzy for a CAS and the ignition coils of your choice and have full timing control. The SRE uses the same user friendly software as the entire line of Platinum ECUs. The best part is that the SRE is priced slightly below the F10X.
We've got a couple of these up and running and have been very pleased for it being a budget ECU. We've also built out and shipped a couple harnesses for a few customers, one of them going in a TII swapped 1st gen as well.
IMO, in the price range, there is nothing that comes close in terms of function, support, and warranty.
