But she's not supercharged, nor doe's she run on Motec.

Besided Hymee maybe cheaper to maintain. A little bit of rum and he's happy! :D


Hymee you really do now have me looking forward to the Nationals. I had all these plans for before the nationals but now they are all on hold to wait and see what you come up with!

 

Well done lads!

Fabrice

 

will the M600 work?

 

I guess the M4 will work. We just had a M800 to play with.

Cheers,
Hymee.

 

Yesterday we spent 1/2 day hooking the ignition control over to the Motec. So now the Motec is in complete control of the engines fuel and spark.

Phil Laird of Graphic Skills Racing is absolute genius. He started with a blank peice of paper in-so far as a tune-up is concerned. Remember, the Motec is in complete control of fuel and spark. This includes which injectors fire when and for how long. And spark, including leading/trailing split.

Without even being near a dyno, he has now tuned it to be completely streetable. I would even let my wife drive it. It drives as effortlessly as stock, without any thought needed.

The results so far are a testiment to Phil's ability and knowledge.

So sucessful has this experiment been with a stand-alone engine management system in harmony with the factory computer, the S/C project is steaming ahead. When I said in that thread that we didn't have any ECU issues, I was right!

Cheers,
Hymee.

 

I can't wait to get our megasquirt project to this point, the Motec's have muc larger maps and a faster processor, along with an extensive list of features.

Did your motec have any trouble reading the ignition wheel?

 

Phil had the renesis running totally standalone with a Motec 18 months ago. Not just on an engine dyno, but in a car and down the strip. But this is not news. I reported it way back when. That was the 13.0 in the 808 wagon.

The "big deal" is we are doing it in harmony with the RX-8 OEM computer, so we don't loose any of the "nice" things, like throttle by wire, DCS, ABS, Aircon etc.

To be honest, based on our experience with Motec and RX-8, there are some un-truths in that website that I just read. But it is total undeniable fact that Motec do build the best engine management systems on the planet!

Cheers,
Hymee.

 

When you know Motec's inside and out like Phil does, this did not present us with any problems what so ever.

A couple of engine revolutions and she is all synched up :D

Cheers,
Hymee.

 

Paul Yaw controlled a Renesis about the same time the first RX-8's were hitting the market for sale. That's how old that article is. At that time he also sold 36-2 trigger wheels to be used with them but no longer does as the Motec can now read the stock wheel. The "truths" that Paul mentioned have long since been updated. That was just the knowledge of the time with an engine on an engine dyno.

 

RG,

Thanks for that. I don't mind it if I have to say "I stand corrected". Unfortunate that the web-page was not up to date.

I knew someone in the US had run a Renesis "standalone" with a Motec way back then, two years ago. I know Mazda commissioned someone to do it, and I believe it was in relation to the US "power issue".

It was described in the same document that said it wasn't possible to "piggy back" a Motec with the RX-8 CPU. If we had ignored that "current wisdom" of the time, and just invested what we did this week, the S/C would have been out 12 months ago. And who knows what sort of wildly ported engine we could have run in a street RX-8 with a MAF-less tune up?

Cheers,
Hymee.

 

G'day mate,

Actually, the Motec could read the stock trigger wheel back then as well. That is what Phil used on his test engine back when I mentioned.

Cheers,
Hymee.

 

I've got a 36-2 trigger wheel that came from Speedsource Racing. They had bought it originally to use with the Motec on their race cars. They said at the time the Motec couldn't read the stock trigger wheel but it became available soon afterwards. I'm just going on what they told me.

If yours currently running on the supercharged engine or is it on an n/a?

 

Guys who cares who knew or who did whatever first , let just get those superchargers up and running whitout major problems on our RX8'S at a reasonable increase in power and price .

Misinformation ....is a good way of throwing competition of the track :D , as you have realised sometimes not listening to "current wisdom "
and doing your own research can pay dividends .

As they say all is fair in love and war

I have a 36-2 wheel on my car as well D:D Stock. Yep, I know you are just going by what they told you. I'm starting to go on what I learn by experience even more and more Like I said, if we did that instead of listen to the FUD back then, the S/C would be out by now. Oh well, if you wan't to see a S/C renesis, there will be one at the Jamboree next weekend.

Cheers,
Hymee.

 

I'd love to see it. Unfortunately it's only about 10,000 miles away!

 

I doubt motec w/ the supercharger be reasonable priced, im guessing this higher quality version be close to the 8-9k range.

Either way I can't wait to see what this kit can do, probably going to be one of the higher quality kits in the future.

 

As i posted earlier there seems to be over 6 different options from different companies with superchargers coming ontu the market in the next few months , so i will sit back and see what they all provide what price and what power figures they put out then i will decide the one that i feel suits best :D

Can't wait to see a MoTeC sub-forum in the future. Is the fuel map TP/RPM with boost comp table or MAP/RPM? I assume ignition is standard MAP/RPM. Last question, how are the 3 sets of injectors staged in the table?

 

Marietta 8,

Good technical questions.

At the moment, we are all TPS/RPM, and haven't looped in a MAP sensor - yet. No boost yet while we are N/A. MAP soon when we go FI.

As to the question of the staging of the injectors, that is maybe the tuners secret j/k Honestly, I don't know.

Cheers,
Hymee.

 

Cool, I thought it was already boosted. When are you coming back stateside? RXeightr is a friend and I am near Atlanta so not too far for a meet. I've run an M4 for a long since 94 and loved it. Sold it with the whole powertrain to a friend so I still get to have a look from time to time.

 

I'll have the cold drinks (and Jack Daniels) here awaiting the next meet. Marietta8 & Hymee together would be a real treat.

Just name the date Hymee.

 

Hey guys,

Here is some footage from a while back. It is when we first got the Motec running with the factory computer on the RX-8. In this footage, the Motec is running only the fuel, and the factory computer is doing the ignition.

Sorry for the mess with the wires. Grandad will shoot me! But it is here for historical purposes, and everyone can appreciate it was done for developmental purposed. Pictures on the "finished" product can be viewed at the Hymee gets Supercharged thread.

Cheers,
Hymee.
