Where can i get a haltec ACU that works on a 20b in a Turbo 2? A freind of mine is doing a conversion, and he need's a haltec ECU to get it to run.

So if eny one knows where i can get it would be grate.

 

Try www.haltech.com and go to dealers.

The only Haltech ECU that is designed to properly run a 20B is the E11, and it's having some significant issues on the rotary platform.

The Microtech LT12, however, costs less than a new E6K, and will properly run a 20B with trailing split.

If you wish, I can get you in touch with a European Microtech dealer.

If you are serious about tuning your 20B you're welcome to me in Stockholm and visit a tuning shop that has Rototest equipment (no rolling road but 2 hydraulic items that bolts to your 5 lug pattern) I am doin some work on a Norwegian 20B this summer which we later shall tune with the Rototest.

 

So the new LT12 has both rpm and load input for the trailing split map? What about boost control?

 

Trailing split is adjustable in 2D over RPM. Boost control is possible, but isn't preferable to a dedicated boost controller (similar to the E6K).

the e11 is a 3d split, and it runs the mop and you can have a pwm to make you coffee

i thought the microtech ran the mop on the 20b as well

So in other words, it can not run a 20B "properly" with trailing split. Not that I think it matters much, but I just want to clairfy your previous statement.

 

Well, nothing but the MT8 and the E11 (when it runs a rotary) will run a 20B with 3D trailing split (and I'm not sure about the E11). So while it's not "perfect", it's better than the alternatives, and certainly meets my definition of "proper".

Well i see that the haltech ECU is not compatibel with 3rotor. So wich ecu is?

I need somthing that will work, and not demand an iq of 200.

 

i'm running an e6k on my 20b, and it runs fine. it would be nice to have leading and trailing split like the some of he newer ecus.

mike

 

what i need is a completete kit. i have heard about a company in the states that sels complete ecu kits for a 20b.

Eny one have eny clueues?

 

The LTX12 and coils are with everything you'll need to run a 20B - harness, coils, ECU, fuel pump relay, manual, even the ECU fuse. It has timing split as I've described earlier.

Not sure what you're meaning there bud...

My car actually went into the workshop today for the beginning of what will undoubtedly be a long and drawn out process; FD 13B twin turbo to street port 20B Gt42/45 single turbo 'swap'...

Here in the UK ECU options were (are) limited; basically M800, E11 or LTX for a 20B - no one is running a Tec over here to my knowledge. And rotary tuning generally is still in its infancy.

I was settled on getting an E11 but as Matt was away tuning in the US I didnt get to order one when I wanted; I'm glad now cause the Haltech Yahoo group highlighted problem after problem with the E11 over the last few months (I unsubscribed some time ago though so things will have improved as they actually get some time on the E11 ECU). I'm not sure whether there are people running 20B's successfully with them yet?? A guy over here who I respect completely has half blamed his E11 (now used as an expensive beer mat I imagine) for the demise of his latest 20B motor.

Any way, M800 is a lot of cash to commit to at such an early stage in development so I've gone with the MT LTX12; simple yet effective. People may say its a bit ferrel in resolution and feature set etc but how many of those have actually run a car day to day with them? More to the point - for the money you cant go wrong. Deffo worth a shot IMO. If it doesnt work out then I'll go MoTeC without a doubt (may well do in due course any way if things go as I plan).

Just about any ECU that will run a 6-cylinder will also run a 20B by firing the leading and trailing spark plugs at the same time. The following EMS products have proven to run a 20B:
Electromotive TECI, TECII, TECIII
Haltech E6K
Microtech MTX-12
Motec M4 series and M8 series
Wolf3DV3

If you want to fire the 20B leading and trailing plugs with a split, then the products below claim do to so. Make sure you speak to a dealer before buying so that you can discuss your requirements. Except for the Motec M800, all of them are new products, and may still have some glitches.
Haltec E11
Electromotive TEC3
Microtech LTX-12
Motec M800
Wolf3DV4 Plus

There is no 20B ECU "kit" available, and the engine swap requires an IQ of 200 regardless of which ECU you use, so have fun.

Proper 20B-REW timing IAW the stock specs: Split by rpm and load
Proper 20B timing IAW racing specs: No split

Split by rpm only will work just fine. However, I just don't want people to think that Mazda has ever run a production 20B this way.

 

yeah the stock ecu has a lot more inputs and outputs than anything else. it would be nice if the stock ecu were easier to mod

mike

 

Does anyone here know of anyone out there who can modify the stock ECU?

 

re amemyia, can take the boost cut and speed limiters out, but its still not very mappable, and you still have the afm

mike

 

Oh ok. I was just trying to find a cheaper way to skin a cat. Well, looks like I'll be NA first, then I'll upgrade the car to take more power second, then I'll do a large single turbo and a decent ECU for like 400-500HP. At that time I'll be looking for a B or C series engine because this one I'm getting is pre A series. It's like #75x or something.

Or maybe I'll put the ECU/turbo and later series engine in a white FC.

 

there ya go

mike

 

Cheap? This is where the LTX12 really shines! You can run a 13B and a 20B with the LTX12, with timing split as discussed above. When you're ready make the extra-rotor migration, send the ECU back to us for a few days and buy two more coils and you're done.

Interesting idea, as this 20B doesn't include an ECU.
