I'm working on a 3-rotor conversion to my FD.
Has anyone had experience with ECU for 3-rotors. Which ones will work, which ones definitely won't work, etc.
Thanks in advance
Larry

 

The Electromotive TEC I can do a leading/trailing split for the ignition. I believe that Microtech can do the same--ask rx720bt. The Wolf 3D will work with a 3 rotor, but I don't think it does the split timing. I have seen people use a Haltech in 6 cylinder mode with both the leading and trailing plugs firing simultaneously. K2RD is running a 3 rotor with 2 E6k's: 1 for fuel and leading ignition, 1 for trailing ignition.

 

Haltech E6K, Autronic SMC or SMC2 or the MoTeC ecu's can all run 3 rotor engines, i dont think ANY of them can run split trailing timing, but it doesn't matter, unless you are trying to pass emissions with them.

Matt Leicher is running a single E6K on his 3 rotor engine and firing both plugs at the same time and having no problems.

Any of the big ecu's can run them.

 

2 E6K's on a 20B !!!! WHY ???? one E6K and an IG5 would do the job if looking for trailing split.

Microtech MT-12 is releasing new software which will allow trailing split and nice datalogging here in the states.

 

I wouldn't run 2 E6K's either. The TEC I can run a 3rotor with the trailing split, and it includes all of the ignition stuff. The price isn't too bad.

 

Personally, I wouldn't touch electromotive stuff. Look how long farrell has taken to tune the 3 rotor he did up. My understanding is that after the car and driver article, the car went to electromotive. I don't know if they got anything sorted out with it.

I am using the link engine mgmt system in my 3 rotor. The are still some tuning issues to get sorted but it works great. The link system does incorporate split timing.

 

You have very little info to be making judgements. The Tec 1 is much better than trying to run 2 different ECU's on one engine. That would be a tuning nightmare. The Haltec cant run anything larger than a 6 cyl. The 3 rotor is set up like a 12 cyl.

 

Where can I get information on the TEC 1?

 

I had a 3 rotor built so I believe I have all the info I need to make a judgement. Perception is everything in life and I understand Farrell has been trying to tune that car for almost a year. I use the link system and find it very easy to use. I looked at motec, haltech, tec 1, link, and others before getting my system.

I am not flaming anyone, just offering my comments. If there are additional factors in farrell not being able to tune the car please enlighten us why it has not yet been tuned.

 

I actually used to work for electromotive so I happen to know plenty about the product and how well it works on almost every application. Because you owned a 20b doesnt mean you know how to tune it. Unless you own a dyno and happen to tune cars all day long. Peter built the car for Mr.Hamlin and the car has been sitting in the shop for over a year. The car is being stored in Peters shop because Phil hasnt taken delivery of the car yet. They end up moving the car in and out of the bay every day and the plugs get fouled up from just starting it to move it a few feet 2x a day. No warm up. Put it back inside at night so its secure but it needs to get moved back out of the shop so they can have room to work on the other cars during the day. Every day the same thing. The car isnt driven except on very rare occasions. 2nd reason it was not tuned up properly at his shop is the neighbors have complained so much about the noise from dyno tuning there has been a warning from the city. He does not dyno tune at his shop now or he can be closed down. Its simple really but people make comments when they dont know any details. And somehow assuptions equate to a product somehow being inferior? The Tec unit always makes more power on the same car when previously tuned with a haltec. On most single turbo 2 rotors you actually will see as much as 20hp more from the exact same car. Not that the Haltec is junk but the Tec is better.

 

Virginia to NH: That's quite a move. Alot of people just don't know much about the TEC. So they just assume it's no good. At least that's my experience.

 

link only has 6 load points per rpm range..................
