The part I like the most is the ecu still has full control of the fans. So fans still come on with the a/c or any other reason the ecu might want them on before 190*f.

Real easy to install too, took maybe 10mins. Paid about $100 for it in his eBay store.
i bought this and my fans stay on while driving and temps are 158 F (30- 40 mph). while parked they come on at 176 F and go off at 158 F. i think thats a little to much. whats your thoughts?? did i get a sour kit?? 158 F is too cool and i dont like my fans running constantly.

Hmm sounds like a bad sensor or something, I would contact them and see what they say. Mine is still working the same, fans come on around 190-195 turn off at 181.

Did you use the coolant hose that goes by the battery box?

Let me know how that goes if you don't mind.

When I bought this kit I didn't do much research on it and it turns out "MindsEyeEngineering" is really a guy named Scott that owned another company that ripped off some forum members here. When I delt with them I had no problems though.

So far service is good we're trying to figure out what could have happen to make the kit act the way it is but he said this the first time it happened so hopefully we can work something out. I'll keep u posted.

Yea Scott that's the guy I'm talking to.

Better Apex Seal lubrication will lower friction, therefore heat...therefore coolant temps.
I believe it is a logical conclusion, however why not do both.

only to a point - there is an optimum level and exceeding that has no benefit .

Anyone care to explain in ATR what these do?

Fan2 - VSS (MPH or KMH??)(Speed at which fans turn off?)
Fan2 - VSS Hysteresis (with in X miles of set speed?)

thank you, that does sound like a logical conclusion... I am assuming that the only way to increase the omp rate and decrease the temp that the fans come on is with a cobb or something similar?

for the omp adjustment--that is true. You have to have something that will access the pcm software.
For the fans you can buy a separate fan controller and install it. You dont need to access the software in the pcm to do it that way. Or you can do it through the pcm with the same tool you do the omp adjustments. Things do get a bit complicated for me in using the software. Others can do it without a blink of the eye.

The kit I used in this thread worked great, in fact I will be selling it as soon as I finish removing it from my car (need to fix/replace hose first.). It's actually a new kit I just got too, I broke the original one when changing my hoses out to silicone 2 months ago.

I just wish I could understand ATR a little better.. I don't like making changes without being 100% sure of what I'm doing. There is a lot of info on this site about it. But getting threw the countless pages of arguing/BS is taking a lot of time.

what is the kit called so that I can do some research on it

and I know how you feel with the bs... people come on here and flame without putting in any useful info and it makes you have to sort through 10 pages of crap to find the one post with any useful info

If you want to increase OMP injection without buying an Accessport, there is the vacuum hose that gives the OMP vacuum. The series 2 tube has two holes compared to the series 1 having 3, or maybe its the other way around. Either way, you can get more injection. Not exactly sure how much though.

Series II RX-8's have a completely different MOP set up.

None of your recommendations work on a Series II with the two EMOP units, plus the 6 Oil Injectors ( 3 on each Rotor Housings) are also different to S1 and do not have any vacuum/barometric tubes attached to them...All the S2 Oil Injectors have a single oil feed line to each with no one way check valve in Injectors or lines like S1.

So far I know of no ECU (PCM) override for S2 EMOP System to increase rates.
