I thought I start a Thread that will help anyone interested in after market ECU units. This thread should help us figure out which ECU does what, and pricing and where to obtain the units , Especially if we are upgrading or installing FI for ourselves... I will start this off and I really need everyones help so please put yor 2-cents in...

1. I know the current Greddy e-manage unit leaves much yo be desired...

2. Greddy is releasing a new version which is suppose to pick up where the earlier version left off.. It would be nice to know what it's going to do, pricing also supposed to be around twice the price of original....

3. Microtech is coming out with a full control ECU for the RX8 shortly, has anyone any updates and what it will do...

4. I left a message for Hymee in PM he has not gotten back to me yet, The favor I ask Hymee was will he give me the info , phone number and or address of TSI in Australia, The company goes under the name Tuning Solutions International (TSI)
also Rick Shaw.. So if anyone else can help let me know... Their unit seems one of the best for the RX8's...

5. There also seems to be a combining or makers of ECU's in Australia , such as Haltech, TSI, afew others that don't come to mind right now. My question is , Does anyone know if they are one or separate systems...

6. Motech - I don't know much about them can anyone enlighten me on this company..

7. I have talked to acouple of vendors with SC/TC projects that they are almost finished but are still having trouble with proper tuning, The current Greddy is giving them trouble especially for the SC...

8. So you see I believe this can help all of us to know which units are out there, by whom, where, how much and what they control..... And guys I'am not biased to any one vendor, as a matter of fact the SFR/SSR seems to run perfect and they are using the TSI- Tuning Solutions International ECU.. So any and all info about these units and or any other units that I may have forgotten please post , for all can benefit... Thanks to all that have been trying to help ...

 

All we really need, is to be able to write maps to the stock OEM PCM. How do you think Racing Beat is able to accomplish this feat?

"ECU/PCM Reprogramming - Phase one of this project has revealed very modest performance gains - work is continuing as time allows."

 

You might be right. Do you think the stock unit will be able to control bigger injectors and how about boost controllers, I'am new at this I don't know That's why I'am trying to gather as much info as I can...Thanks..

 

They work very closely with mazda and probably have the same tools that mazda uses to program the ecu. Furthermore, astra-racing in italy also has the ability to program ECUs. Apparently, it's not as difficult as we all thought.

Now saying the stock ECU can do what we need to do may not be entirely correct. Keeping the stock ECU and changing the maps is nice and all, but there may be some features that the aftermarket ECUs have to offer that the stock ECU cannot do.

we will see.

 

Larger injectors, yes definitely.

Injectors are just duty cycle. if you replaced your injectors now with larger ones, all you'd have to do is recalculate the fuel map based on the new size of the injectors and adjust the duty cycle by that factor across the boards.

Boost controllers, I doubt, but who knows what mazda has hidden in that ECU.

As far as i know TSI Tuning solutions Australia are no longer in bussiness and Rick shaw( racing car driver ) used one of their units but they are one and the same .

Hymee posted that one of the original TSI partners may be in a position to continue helping in producing a ECU compatible with the RX8 .

cheers

Maurice (Canzoomer) is also working with a company in supercharging the RX8, obviously using his own unit with added capabilities .

cheers

Hey Lock&Load, that's what I'am hearing to, that the TSI co. split, But SFR/SSR is still getting their ECU's from which ever partner that is still in business.. I needed that info to because I talked to the guys at Pettit and they thought the TSI unit may work for them alittle better... So as you said if any one else out there can help us please do..Comeon Hymee it's in your back yard....

Also what about the other units I mentioned earlier, does any one have any info...

 

This tread might help.

Please don't laugh, but does anyone plan an aftermarket ECU for the AT?

 

It will all happen in due time , however all the aftermarket companies seem to be taking one hell of a time tryng to bring out a unit thats compatible with turbo/supercharging and cost effective Motech is problably the best but costly .

cheers
michael

 

Thanks Lock&Load, I check it out man is something funny here or what.... I went to the Microtec site, and the Motec site and Haltech site, guess what they are all located in Australia and we know the TSI- Tuning solutions international is located in Australia, I wonder if there the same company with different badges ...

 

the AT verison is probably easyer to deal with than the 6port (neglecting the how the engine managment deals with shift patterns ect). the bigest problem is the drive-by-wire IMO.

have a look at re-amamyia they have a AT turbo kit so they must be doing something to change the fueling.

 

emanage and bigger secondary injectors, as far as I know.

 

megasquirt (http://www.megasquirt.info/) is a build it yourself standalone ECU which may have some potential with our cars. It runs about $200 all in, and you have to do a little soddering, but other than that its pretty esy to use. The software is open source, so there are always people updating and improving on it which is nice. Rotary God is using one for his 1st gen 7, I've seen it running on a laptop and should have enough functionality to control everything except drive by wire throttle.

There are people working on the code so as to allow for leading/trailing split control, something I'm not sure the other's do.

If this could be made to work with our car, it would be an inexpensive ecu solution for the 8.

 

Just read article, interesting.. Thanks..

 

Hey Smrx8 & Loack&Load thanks, Talked to rick Shaw today, very nice fellow. TSI will still be selling their ECU's , their not cheap, but seems well worth it though for what it does...

 

I believe RB pretty much has the PCM figured out, and I mean ALL of it. I'll bet they'll come out with a complete reflash soon. I also believe they are working with several FI vendors on doing the engine management with the factory PCM. How can they do all this? They are very connected with Mazda.

 

Has anyone contacted RB recently, and if they reflash the PCM, will we be able to retune ourselves. Say we want to retweak the unit with our Profec- E-01 I wonder if the oem PCM will let us have that kind of control.. I thought Greddy was well connected with Mazda..

 

Greddy is VERY connected .... like donated cars etc... but as far as tuning they dont do reflashes ever so they keep making the emanage do more things to get around the stock ecu issues. Like the o2 simulator and coolant sensor simulator, those were both very smart ideas and most importantly for greedy VERY VERY CHEAP to do. But whatever works, thats whats important.

And a reflash would be nice however all cars are different thats why some people have problems with the emanage and others dont. No two cars are every identical.

From my experience the Canzoomer ecu had trouble getting around the open loop ecu adjusting it self. They used a clutch on the supercharger pulley to engage boost only at certain rpms. Unless something has changed which is very possible.

And I think the Haltech will work quite well piggybacked on the stock ecu. We are having trouble getting the stock hall effect sensors to work as triggers. Haltech australia is working on it now... we might use a motronic wheel for now if haltech doesn't figure it out soon. I am giving them til wednesday to think of something then I'm ordering the wheel. So maybe i'll have some info on the haltech soon.

 

Man this is fustrating Everyone seems to have their turbo/supercharged kits near completion but no one has TRULY sorted out the ECU and without the correct tuning these kits are not going to work at their full potential

cheers

Omiron, I just talked to Mike from RB, and seems their still along ways from being able to reflash the OEM and make it mean something...

 

we sent them the trigger wheel info over a year ago, i wonder what the holdup is?

mike

 

you got me bro... you would think that would be an important project for them but i guess not.

Rotorman,

Hey - I am not ignoring you. I did reply to your PM, and gave you some details, about as much as I could, really.

Like I said, TSI is no longer a company, and you will not find a site about them. They used to have a very small and modest site.

Having said that, the major player is still developing and building these units under a new company, having split from his former "partner".

And I did mention in the PM that he is not interested in selling directly.

I have just spent 20 minutes or so talking on the phone to him, and here is the current state of play:

The new company is Automotive Control. The units are being sold under the brand of "PowerMod". It is our intention to use these units with my Screw Supercharger project, subject to testing etc. I have a relationship with Automotive Control to enable us to OEM the PowerMod units.

As for the North American market, he is already in negotiations with some potential "resellers" in the form of workshops. As I understand, there is no firm or final arrangments been made, and I am not privy to the names of those companies.

As for me, if I want to sell them to the US I can, but I would need to establish a partnership with a reputable tuning house to start with. In that vein, I would rule out anyone who wants to "trick the MAF readings", "trick the O2 sensor readings" or even "Tune in closed-loop".

So, I hope this answers any questions. I don't like to think I am seen as withholding information from the community. With all those posts I clocked up, I thought I was contributing something

Cheers,
Hymee.
