both of these mods are said to keep the temp lower by kicking the fans on sooner..(aside from the pcm flash adding a little punch to the powerband)

Are they doing this by the same means?..

If i have the PCM flash already, does this render the Mazsport mod obsolete?

just a thought.. some flames and sarcasm are to be expected.

I don't think this a "versus"... Mazsport cooling mod is pretty cheap. Getting both mods is very "do-able" and helpful.

One advantage of the Mazsport mod is that if you get your ECU re-flashed by mistake (by the dealer or something) than you are covered. You can also have the "peace of mind" that your fans will definitely kick on when its hot.

they both do it the same way - kick on the radiator sooner than stock.

i don't know which one is BETTER, for all I know, they could even be exactly the same.

There wouldn't be a reason to buy both though. At least not if cooling is your primary reason.

fair enough.. was heading out to mazsport at the end of the week. Was debating whether or not to throw that in the mix.

- cooling is pretty serious here in L.A., Last summer was almost unbearable. days and days of 110-119 heat, even at night.. and they say this summer is gona be WORSE!!.. I think im heading somewhere north for july and august... maybe oregon for summer skiing

good question....I think the best answer to this question would be to have confirmation from both companies at which temp the fans turn on.

I just got the RB flash, but haven't heard the fans kick on yet. Of course, it is still somewhat cool here in Cali....

During the summer months, when autocrossing, the fans definately get their work.

I have the RB flash and the fan did turn on more often than before, and summer is coming so Im expecting this to happen more often.

so over all, the RB PCM flash is better? and at what temp. does the Mazsport mod start the fans??

mazsports seems to kick on at 191 F and keep it on till the car is under 179 F on my car...

The RB controls the fans strictly through the ECU programming and requires no cutting of hoses, running of wires, and connecting into the fuse box. The Mazsport unit requires all of those things and based on user comments on this board, also seems to create some idle issues when both fans kick-on at once. The price of the Mazsport is less than the RB reflash for sure, but as mentioned you do get other performance benefits as well and lets be real .....$300 is pretty low-dollar for a performance flash and better cooling all-in-one.

The Mazport kit seems to be well thought out as a package, but the idle issues that people have reported is a deal killer for me. Too many people report this issue for it not to be a problem, and it basically indicates that the electrical circuit and load created by this add-on system must not be completely de-bugged yet. On the other side of the coin the downside to the RB flash is that if it gets flashed over by the dealer, then you are back to stock until you get re-flashed again with the RB flash. I have an answer for that, make sure your ecu is at the latest recall factory flash before having the RB flash loaded, and then specifically warn the dealership not to re-flash your car.

As someone mentioned, the idle issues might be related more with the int-x than the cooling kit. I have had idle problems sometimes just by turning on my headlights.

BTW - I just posted a DIY fix for the idle issues:

http://rotaryinsider.com/rx8-92.html


As I said, I really think it's more to do with the int-x idle than the cooling fan mod, though this issue shouldn't be a deal breaker. The fix listed above should make it neglible.

Interesting. So its really the folks that have the int-x EM that are experiencing the idle issues then? I know that one of the comments I read about the idle problems, and I think even a comment about having the car die once when both of the fans kicked on, may have been from one of your posts. If the idle issue is not a problem for cars with the stock ecu set-up, then the Mazsport solution becomes a great option considering cost and value in minimizing wear and tear due to running the motor hotter than necessary. Being located in New Mexico with temps reaching 105F+ sometimes, this is a serious concern to me and seems to be a logical mod with no downside.

mysql101

Until I had the cooling fan mod, I had no problems with the int-x... so I wouldn't characterize the int-x as inherently having idle issues either.

I'm confident we'll see these minor issues worked out, but unless I mention what (few) issues I have, they will never be resolved.

N10S

I understand that it wouldn't be the int-X having the idling issue on its own either, but based on what I read in the link you provided it may be a combination of one companies engineered solution not accounting for limits or variables that another product might have. Either solution on its own may be fine, but the mesh of the two results in an unforseen result. I have been a telecommunications voice and data systems guy for years, and I understand the concept as it applies there all too well.

Btw- I wasn't trying to be negative about your posts providing info on the idle issues, but just suddenly realized that some of those posts were probably from you and that the whole tie-in with the int-x suddenly became clearer. I for one, do appreciate the fact that folks share information to help get things resolved.

Thanks

im also experiencing the idling issues with the mazsport controller. I dont have a turbo and im running the latest flash from mazda. It's very annoying when you come to a stop light and get the feeling that engine is about to stall.

interesting... try doing my DIY fix and see if that helps you..
