when it's above 8500, the stock rotor's gear might loose and allows the rotor to psychically "touching/striking" the irons. It's not just a Renesis thing. Its a known issue for decades.
That's why there is this snap ring thing service offer by Racing beat. it's an expensive fix(for a snap ring that cost like maybe <5 bux?) but it helps.

10W30W engine oil hey...so where is Jackson!..
Glad to know someone else (Star Mazda) knows which coloured Injectors go into an S2, as MNAO DON'T, their advice to their Mazda Dealers is appalling wrong (yet again)....been this way for over 10 months..
I did not want to post this 'M-tip', I have been sitting on it since January this year in the 'hope' it will be fixed, but, communication from myself and a few US Dealers I know have tried, it all falls on deaf ears @ MNAO, including the useless J Barnes...is it any wonder this Upper Managerial mob at MNAO all need sacking!....and yeah it make me mad!.
You have a "President" that is an old FORD hack!
The old Ivory Tower of management...BS castle!
You guys pick the error in this M-Tip..

is it a surprised? we're talking about MNAO here. a company that probably 1/2 the people working inside have no idea what they are selling (Rotary Engine)

Good stuff guys, I did the SSV test this morning and Team is right.
Ash8,
Thanks for the M tip but I can confirm that those wire colors listed are not correct for different year 8's. We confirmed this last month between an 04' and 05' RX-8. The wire colors were different for some reason. I also spoke to bumblebeerx8 as he posted the info and he too found his wire colors were different.

Did you not read the whole statement about fuel and spark cut?
And this is referring to the race car still, which has a different ECU and different rev cut point than our street cars. That being said, shifting in the 8,000s and not crossing 9,000 is still a good idea for us.

When we hit "redline" and hear a beep at 9k our engine is actually at 8600. I have taken my engine past that plenty of times with no noticeable damage. I've mis shifted and went to 10k as well, I'm sure when I crack my engine open I'll see some very light damage, might not even be noticeable to the naked eye.
They clearly sent out this bulletin because teams were complaining of engine failure. They are required to use the Renesis, and were most likely having a bitch fit because engines kept blowing. In 2010 they made several other changes to the map for cold starts and fuel trim, in 2009 they changed the rev limit from 8300 to 8600. They make sure the engines stay below 8600 because that's where these things live all day. For us daily drivers, the difference between 8600 and 9000 isn't going to blow up your engine in in 2 seconds, come on guys...
You are seriously comparing your Daily driven occasionally tracked cars (exception of a few track only 8's) to formula cars. With the only commonality the Renesis core. They have different water pumps, pulleys, throttle body, lubrication and cooling system, with a stand alone ECU, inside an 1800 lb frame.
We have a bunch of random ****, electronic everything, 500 lbs of wire in a 3000 lb car. Its not the same car, its barely the same engine.
I realize that most of you in here get that, I just don't want more misinformation to spread around these forums. We have enough in circulation already.

Could not agree more with what Shady says...
And 9K thanks for confirming the Wire Colors are also wrong for Series 1's in that MNAO M-Tip...!!
So, we also have wrong Injector Colors and Part Numbers for the 4 x 2009 (S2) Injectors and this...I hope the 6 x 2004 S1 Injector colors are correct, sorry, but I don't have these in my OE parts stock to visually verify.

9K...on OE Engine Wiring Harnesses for Series 1's...
There were a total of 9 different iterations made, 3 for Auto 4 Speed, 3 for Manual and 3 for Auto 6 Speed...
Roughly the original Harness, then ALL 'a' one way change (new for old part ONLY) for the 9 iteration changes, again roughly up to 2005, between 2005 and 2007, and from 2007 until Series II's, which are different yet again.
In the end though they all supersedes to just 3 different Engine Harnesses in Series I's, one for Auto 4 speed, and one for 6 speed Auto, and one for all S1 Manual Trans.
I can't confirm all the actual wire color changes for all 9 iterations, but I have no doubt 9K is correct seeing all the errors in anything MNAO puts out in their own M Tip Bulletins.
Factory TSB's from Japan are just copied directly, almost word for word.

The colors on Houston's 04' were different from bumblebeerx8's 04'.

Yeah Houston and I compared two different diagrams and descriptions and his wire colors were different from both. A couple of them matched and then there would be one or two wires that were a totally different color combination. I called bumblbeerx8 and he was like, "yeah I have seen different colors as well" So basically we just kind of put them how they appeared to go based on length, etc. We got it right though.

not really, its a race car. we run with star mazda, and they get 4, 20 minute sessions a day, for 2 days. with ~2 minute lap times, this is about 10 laps of a 3 mile track, so they do about 30 miles per session. 8 sessions a weekend.
this is only 240 miles per race weekend, and i'm sure they all change oil between races anyways, even though it looks like they don't need to

Where would fuel be getting into the oil? Leak down from piston engines makes sense, but we don't have a leak down point for fuel to get to the oil pan? Unless it's going between the housing and the irons, which would be concerning for different reasons.

Rotaries have a lot of fuel dilution actually. My test have shown that Mobil1 tends to deal with it a lot better than my previous oil did though. If you look at some of my old samples you will see the high % of fuel showing in the oil.

Nope, oil pressure regulator mod. Mazmart and other builders make them. My Mazmart mod made my pressure a bit higher than what what done by Pineapple Racing on my current engine. I currently see max pressures of about 100PSI versus 120-130PSI with the Mazmart mod. Stock maxes out at 70PSI give or take a few PSI.

Not for me , as many are Star Mazda specific, many look genuine Mazda, but there is no corresponding MAZDA Part Number to cross reference that I can see....
Find that and you have the holey grail...well sort of.
Example...Fuel Rail Hose..
FUEL RAIL HOSE
050-587 FUEL RAIL HOSE (050-556)
Now is it S1 or S2, I cant tell from pic..
N3H1-13-495B Fuel Hose Series 1
N3R1-13-495A Fuel Hose Series 2
