Hey Guys! First post here as no-one has realised what theyre missing out on in the UK!

What management system do you reckon is best for a cosmo 20B? (will swap loom and block to FD3s shell later )

Tuning not a problem, anyone any experiences with programmable systems (Link, Autronic, Haltech, Motec...) I know power FC backwards but not an option unfortunately on 20B! Cheers!

 

AEM EMS (GEMS for UK) can run split timing on a 20B.

 

They dont make an PFC for the 20b?

 

i have a haltech e11 and (key words here) when the car runs, its great! they have some sort of heat issue that shuts down the output side of the ecu semi randomly. it absolutely runs like stock (or maybe better), and i get excellent gas mileage (16city, 19freeway, sub 9 ish if i beat on it) and i can push it thru intersections like butter!

i had an e6k before that and it ran ok

 

Just for clarification, there are two AEM corporations that make an EMS:

1) AEM Australia - These are known as the "Wolf 3D" systems. The Wolf3D V4 Plus will run split timing on a 20B. The regular Wolf3D V4 will only run split timing on a 2-rotor engine, but will run a 20B with simultaneous timing like a race car.

2) AEM USA - These are known as the "AEM Plug & Play" systems. While they originally planned to market a "Race" model that was universal, they decided to market only models that are dedicated to a few particular vehicles. The Race model supposedly would have been able to run split timing on a 20B, but there are currently no production Plug & Play models made for a JC Cosmo. It is possible that a Plug & Play model for a 3Gen RX-7 could be modified to run a 20B, but I have seen no advertisements indicating this.

Not that I am aware of. It probably wouldn't be a very smart marketing move to make an EMS dedicated to a limited-production JC Cosmo that is no longer in production.

Motec offers the best EMS solution for a 20B, and every serious race car I have seen with a 3-rotor or 4-rotor engine has used a Motec EMS.

Other less-expensive solutions that will allow for split ignition timing are the Microtech LTX-12, Haltech E11, Electromotive TEC3, and Wolf3DV4 Plus. I know that Pettit used a Link EMS on their 20B Banzai conversions, but I never got around to asking them if it controlled split ignition timing.

 

Also, as a note, I deleted your duplicate post in the EMS forum. This is the correct forum for your 20B posts, and you will get better responses here.

 

Interesting info about AEM Austrailia.

Ok I found a relevant post:

Note: it will plug into the factory FD harness.

 

the electromotive tec3 will also handle split on a three rotor and if I ever get off my butt I will take my 13b out of my race car and put a 20b in it

If you have the duckets, the Motec M4 or M8 is probably one of the best you can buy...Haltech is good for lower budget build ups...

 

I have a Brand New Microtech LTX12 with all the options inluding the dash display, wide band option, 3 bar map, 3 bosch coils, software and cables to hook up a laptop for programming.

I would let it all go for $1300 shipped. It has never been installed!

 

...and I'm still waiting for an answer how an LTX12 with only 4 discrete ignition channels can "properly" (key word) fire a 20B?

Electromotive Tec3. In addition to Electromotive's usual good points, the Tec3 benfitted from Russ Turner's involvement in design and development. Before working for Electromotive, Russ worked for Peter Farrell Supercars, where he got hands-on experience tuning and tweaking the three 20B cars that PFS did (including mine). He was able to add features to the design that support the 20B.

One nice feature is that the Tec3 will support the correct tach output for the 20B. (My Tec-II requires an adapter.)

Ed Taylor's 20B-powered FD was recently upgraded from a Tec-II to a Tec3 with a Wideband by PFS. As a result of the more precise control, the motor--a ported, single-turbo 20B--was able to pass Maryland emissions testing.

A Tec3 upgrade is in my future.

 

I am currently using the new closed loop wideband feature on my two rotor car and it appears to be working great. Definetly a nice feature.

Not quite sure what you mean? the LTX12 has 6 drivers for ignition.

It explicitly states that the LT12S (yeah, it's not the "LTX12") has 4 ignition outputs.
Is this a typo?
Does it steal two extra outputs from somewhere else?
No one can give me a straight answer.

Ted download the wiring schematic for LTX12 ecu. It shows all 6 of the ignition outputs. I think that is a typo for the LT12S.
