I know there are a lot of aftermarket ECUs out there now but in my experience there is nothing better than a MoTec, We have benn working along side MoTec for 15 years now and they have developed so new goodies for us Rotary lovers, The new M800,M600 and M400 will work very well on a Rx8, they have software programed now for the electronic metering pump and drive by wire throttle, also they run there leading iginition in either wasted spark or split leading both running rotary split, The wide range of control from these units are way above the rest. If you need any info I can help with your questions, We have in our own race car a fully loaded M800 Ecu and fully loaded ADL Dash along with all the sensors and software,

Thanks

Does the motec keep the TCS/DSC? Is it a plug & play, or does it require a bit of wiring work to install?

wakeech

hahaha...
...no, it's a stand alone. all it will do is run the engine. brilliant at it too.

you lose absolutely (or very nearly) every single other electronically controlled thing in the car using this.

paradigm

The "hahaha" was a bit out of line. I know a motec is a stand alone. I asked because losing all of the features of the car by using a stand alone isn't always the case. On an automatic FD RX7 just plugging in a new ECU will eliminate the HOLD function of the transmission, but with a bit of wiring work the feature can be retained. I know people who wired full stand alone ECUs to work piggy-back style, just so certain features could be retained. So perhaps I should rephrase my question to "Is this easy to do with the motec."

wakeech

sorry , i'm just a giggly kind of mod, i'm not trying to be condescending, just happy.

*shrug* if you want piggyback functionality, i'm not sure that going for the extra costs (both monetarily and time-wise) of trying to wire a Motec into it so neatly. MazdaManiac (formerly Maniac) has had tons of success with his considerably less sophisticated (next to an M800 unit, obviously) Greddy E-Manage.

unless you're planning to strip the luxuries out of the car (or at least not use them), take the motor apart and put it back together to scream like a banshee, a Motec unit is both overkill and unrealistic.

paradigm

I would, but as it stands it seems like the only things able to be controled by the emanage right now are modifications to the airflow signal and leading plug timing. I want to be able to control the injectors directly along with leading/trailing ignition timing/split.


Hell, it's not like I can afford any of this stuff right now after my tranny. lol.

rxturbo

well, The m800 will work as a piggyback unit and it will control traction control and other items you throw at it. Idle speed control air cond and other things, The m800 can be configured to any controllred item with its user adjustable input and output controls. I have a lot of work with MoTec and know the team, and if there are most things that need doing with rotarys and there cars then Ive had my fare input.

So i wouldn't say its a waste of money considering what it can do, and put along side with the MoTec dash the uses are infinate.

You can control the injectors directly with the E-Manage. There just isn't any benefit when you are N/A.

You can also control the trailing plugs if you desire. There just isn't any serious power benefit there, either.
Modifying the split isn't directly possible at the moment, but I'm not convinced there are any N/A power benefits there either.

wakeech

...in the stock, relatively mild build from factory.

MazdaManiac

iTrader: (3)

Well, yeah.
If you are going to tear down the motor, port it, change compression, throw a T4 on it, ect. that is another story.
Then again, who would care about their TCS/DSC/EPS/ABS if they are going to do that to their motor?

Also, I'd argue that the Renesis is hardly a "relatively mild build".
Look at the power output. Now compare that to the old N/A 13b.
I'd say they are pushing it pretty hard while keeping its civility.

wakeech

yeah. 230-240 hp over 160 is pretty huge, with all they tacked on like an extra grand to the redline, increased the compression ratio, and have that super slick induction system... but i like to be optimistic, and saying "relatively mild" is wishful thinking (and relative to my ultimate dream build... which doesn't have a T4 on it)

IKnowNot'ing

Your own opinion of course. What else have you experienced? Bosch, EFI Technology (Italy, not USA), Pectel, TAG, MBE, GEMS, DTA, Haltech, Sodemo...

Does this mean that MoTeC specifically developped a software for the Renesis engine, that can cope with the (very strange) OEM trigger wheel pattern and trigger offset ignition on the same rotor?

For the rest of the functionnalities you mention, you'll have to let me know of a major ECU manufacturer that does NOT offer them.
Looks like most of them are 'optionnal' on MoTecs (= $$$, I guess).

wakeech

just the number of bits in the data sampling, and the renown of the easily available hardware puts Motec in the highest echelon. are there other competing products out there that are just as good?? sure, but who cares, this thread is about the Motec.

anyhoo, brand favouritism aside, Paul Yaw already designed a trigger wheel for the 13B-MSP a long long time ago to work with the Motec.

IKnowNot'ing

That's also what I thought. Which actually means that any ECU with 4 ignition drivers and injection drivers, Electronic Throttle Body driver and software will work with this Rotary too.

So I don't see te purpose of you post at all ! Free advertising maybe?

If I'm wrong and MoTeC did develop some software for rotaries (I'd love that), let me know because, although not a MoTeC user so far, I might be interested.

And just to let you know that I have nothing against MoTeC, I confirm MoTeC is good, very good in fact.

wakeech

the purpose of my post??

you asked if it would work with the timing, and i said it did.

you were bitching about whether or not Motec is the best, and it seems that's also been settled.

what was the purpose of YOUR post??

IKnowNot'ing

Are wakeesh and rxturbo the same person?

I'll call MoTeC-Europe to get more technical info...

wakeech

haha, i think you're reading way the hell too much into this... rxturbo's post is boarderline free advertising at best, no we're not the same person.

you wondered if the M800 would be compatible with the 13B's ignition timing, and i said that Paul Yaw has made a wheel that has been designed specifically for the Motec brain (i'm not sure which computer he's using... but i guess they all sense it the same way), that's all.

and btw, it's 'keech... sharp sound there, maybe some 'keech-uh action goin' on... i'm not the wiggity widdity waquiche dude, it's wakeech. :D

IKnowNot'ing

Sorry Wakeech for mistreating your name.

I was indeed 'targeting' rxturbo but quoting your post.

And thanks for the link, I will have a look later.

rxturbo

Yes MoTec have specific software for the Renisis motor, They have been for many years now been writing software for the rotarys with factory crank angle sensors and tps switches for the ser 4, 5 and then also for the ser 6 and cosmo motors with there ref and sync crank pick ups also with there electic metering pump, And now the reason for my post is because as a qualified dealer I just thought I would tell people in America and the world that they accomodate for the reneisis motor. Including its electric throttle and metering pump and its single pick up crank wheel and manifold solenoid controls 4 and 6 port plus sequential injection and ignition. Now also Ive been working along side them to write up some software for the fuel pump duty control because as you know rx8's have no fuel return line and use the fuel pump in a duty cycle setup to control fuel pressure. now if there is an ecu out there that can do all this plus more well tell me. All of these item come with the base model Motecs and there options are data logging, advanced functions, lambda options wideband and other options mainly for racing.

Thanks

Thanks rxturbo for the additional, now complete info.

So has anyone installed a MoTeC onto their RX-8 as yet? (rxturbo- have you done any in Melbourne?)

takahashi

It is about time to have some good Australian product.

Waiting for so long for it and not particularly happy with Unichip (for a lot of reasons ).

I am willing to be the guinea pig here (sorry if that offends you). Better still I am happy to be your first customer

Please PM me with your details and I will try to call you in this busy week.

Cheers

Taka, the enabled M800 is $3527, then you have to add loom, sensors, connectors, labour to install etc. so it is quite an investment. Then you have to find someone who can tune it!

But you really won't get better than MoTeC.

takahashi

That is what I heard... that is why it is a serious commitment. The cheapy Unichip as disappoint me from what it can do and still cost me $1300 installed.

It will take a lot of thinking and learning to know which one to go for... of course the timing of it. I heard HKS supercharger will be tuned my MoTec... is that the case?

Anyhow it is an exciting news and I will gather my money soon.

BTW, what is the realistic gain at the flywheel... 20ps may be. This will be $50 for each ps.

rexi

taka ,
rxturbo ala Wayne from selectmaz is very knowledgable and knows his stuff.I recently delt with him when he installed an aluminium flywheel in my 8 and I am pleased with the results.
