It is not without trepidation that I bring this up, since some people think I am bashing MS accessories. I'm not, I just like to get to the bottom of things, just like on the warranty issue. Anyway, I saw this post on mazdas247. Anybody got anything further on this? I had believed it to be just a rumor, but am now starting to wonder again. Were they BS-ing this guy? I mean, how much longer would it take on the install to do the reflash? I asked if there is a version no. for the reflash and will update if so.

Jsut a note to all...the ECU reflash rumor is not a rumor. I was talking to the Mazda techs who did my CAI yesterday, and they said that is was very important to reprogram the ECU after the CAI is installed. (Which coincidentally, is one of the reasons it too longer than they expected to install it. They were initially thinking about just the parts installation, not the ECU piece.) They said it was required to prevent possible engine damage due to an incorrect A/F mix.

So...if you are installing a MS CAI yourself...be warned, you are missing a critical piece of the install until you have reflashed the ECU with the correct software image to match the CAI.

my contact at the mazda dealer says it is only the reset... no flash. someones leg is really gettin pulled here.

If the car will make even MORE power with a reflash, I'm loving this CAI even more. It's fast as is so if it is true and verified with a work order sheet, I'll happily take myself down to my dealership and get a reflash! 8)

Can Josh at Tomkin verify this out for us?

My car also got an ECU reflash while it was at the dealership this weekend getting the MS CAI installed.

I do not know if the reflash was required for the CAI. I had asked when dropping off the car for them to check if any ECU updates in general were available.

When I picked up the car the service advisor went over what all had been done to the car and he as well as the paperwork specifically mention an ECU reflash. The service advisor did not know exactly what the reflash fixes or corrects.

I will look at the paperwork more closely this evening to see if it mentions a version number or anything.

It's being pitched as a engine safety issue rather than a speed issue. My understanding is that leaner mix can cause the engine to overcompensate or some such. Anyway, interesting development!

there is no reflash for the MS CAI install if any dealer says so they are full of it! there is a reflash as part of the p2006 code fix nothing else don't let a dealer say they need to install it or charge you because there is a reflash for your MS CAI they are wrong and i would like to know what dealer says that.

 

[awdturbo]

Hmm...that is interesting. I just hope the reflash doesn't "undo" whatever gains the CAI gave the car. That would really suck. :lol: It seems that the MS CAI gives about 20ish HP. I hope those who are dyno'ing their results will get a reflash and redyno to show if it does indeed diminished the power.

I don't hear or feel the engine knocking but I have gotten a slight stutter maybe once or twice when going full or almost full throttle. Reminds me of a badly tuned specific RPM range, like when I was tuning my DSM with a MAFT and 5 knob afc and I had an area too rich.

*EDIT*
Josh swooping in..hehe. Good to hear!

Two separate dealers so far said there was a reflash, but no specifics yet. Coulda been for something else.

it is there is a reflash out but it has nothing to do with the MS CAI or anything like that it is a fix for the p2006 and threads like this just cause the rumor to grow. i contacted mazda and they emailed me back and said there is for sure no reflash for the CAI out.

I thought the P2006 was a cold weather issue. One guy who has had the reflash is in TX and another MD. Are they reflashing everybody? If so, can you provide any more info about the nature of reflash and whether it's optional? I don't want to go in for an oil change and get a reflash for something that doesn't even affect me.

As far as rumors, this one has been around for awhile and, afterall, this is . . . the internet. Where truth, 1/2 truths, and outright falsehoods get sorted out in the ongoing dialogue.

well if you go in and ask if there is a ecu update they will find out yes there is and might do it. If you have the p2006 code they will do it as part of that too. I have no idea what the reflash does but its listed in the tsb for the p2006 code.

What's this crap???

Quoted..
Interestingly enough, he said there was a reflash for MS3s, but it had nothing to do with the CAI. He said it was to reduce their output because of wheel spin problems. This he said, is done to new MS3s before they are sold to customers....so "we" would never see it or really know about it.
End quote

So my car will have reduced power when I get it this week :shock: Or just more rumours?

i would say more rumors we don't reflash any speed3's before selling them. It is known that they are tuned down a bit from the speed6 since its FWD but thats all the dealer does nothing.

Yeah, you have to remember that we probably know more about the individual models than most dealership people (Josh excepted). Yeah, the MS3 is "retuned" to 263 vs. 274 hp for the MS6. Mazda initially said it was b/c of tight exhaust routing out of our smaller engine compartment. But since the MS6 has AWD, you might just as well speculate that it's a wheelspin issue.

Go, Josh! Man, all over it, just like white on rice. The free interplay of ideas in action revealing falsehood and promoting the diffusion of truth. . . in the long run.

 

[Trubopower]

This is what the reflash is.

Remove negative battery terminal

Put back on

Drive 50mi

Wow magic reflash.




If they really reflashed it tell them to give you the version info and all the flashing information.

Exactly what the installation manual says regardless if installed by the owner or a Mazda tech...

 

[diablospeed]

a tech's idea of a "flash" is most likely different from ours. There is nothing associated with the CAI in any way shape or form. the cel p2006 "flash", where it might rethink the engine to ignore the faulty signal from the intake runner, still has nothing to do with the CAI. Tonkin explained it very clearly here, and I can tell you also.... there is not a "flash" in relation to power for this car. i am glad that we can get these questions answered here!
