Took the speed6 in today for some warranty issues and a CEL. I complained about a stutter or hiccup sometimes in 3rd gear only while I am running through the gears. After the tech looked they told my there was an new flash that should correct the prob. here is the info i have on the new flash---file # SW-L38KEB000

Is there a place to find out wtf these flahses actually change in the code? I mean it really isn't that complicated to make a car run better, but if all they are doing is small adjustements and making it even richer it's worthless for those who want performance.

Oh great, here we go again with another reflash that ruins power delivery and makes the car slower.

This is certainly concerning. Perhaps Mazda will start offerring free dyno runs before and after you bring your car to a dealership? :sarc:

Don't freak out guys. Relax, take a deep breath.

Subject:
MIL COMES ON WITH DTC P2407 (LDP SENSOR ERRATIC)
Bulletin No: 01-037/06
Last Issued: 11/7/2006

BULLETIN NOTE
This bulletin supersedes the previous bulletin issued on 09/01/06. The APPLICABLE MODEL(S)/VINS has
been revised.
APPLICABLE MODEL(S)/VINS
2006-2007 Mazda5 vehicles with VINs lower than JM1CR**** ** 133076 (produced before July 29, 2006)
2006-2007 MX-5 vehicles with VINs lower than JM1 NC**** ** 126015 (produced before August 7, 2006)
2006 Mazdaspeed6 vehicles with VINs lower than JM1GG**** ** 108267 (produced before August 2, 2006)
2007 CX-7 vehicles with VINs lower than JM3ER**** ** 129357 (produced before August 3, 2006)
DESCRIPTION
Some vehicles may experience MIL comes on with DTC P2407 in memory. This symptom is due to abnormal
current in the LDP sensor which exceeds the threshold of DTC P2407. The design specification does not meet
the market need, so the PCM software has been changed to resolve the concern.
Customers having this concern should have their vehicle repaired using the following repair procedure.

I've been lucky so far. No CEL's or problems on my 3/06 build date MS6. Of course, I only have about 500 miles on it...

I don't really mind the flashes, even though I haven't had one done yet. It seems with a car that has such a sophisticated computer as the speed 6's, it going to be expected they will release flashes to address certain issues.

*shrug*

It will be nice when I get my Autoenginuity tool and I'll be able to check on things myself before heading to the stealership...

I don't see how that will help your hiccup. All the LDP does is maintain vacuum in the emissions system to detect any vacuum leaks for emissions. We do CEL problems all the time and they are evap leak detected or LDP failures etc and never have a customer say the car drives different. Mine has never accelerated smoothly since new and never has a CEL on. Feels like the throttle glitches or something drops out for a nano second a few times in every gear.

experienced the hesitation, but not bad enough to make me want to get rid of it..... and for some reason, i think it could be corrected on the dyno.

I had a "hiccup" yesterday. It was very very short, about as long as a "hiccup". Never had it before or since then. It was when I was getting on it in eithier 2nd or 3rd gear.

I had the problem ever since I picked up the 6, I just got use to it. It seems like every gear it "hiccups". Maybe things will change once we get some tuning

It seems that this is just a minor reflash. That's good news. It did get me thinking though. With all of these reflashes, perhaps Mazda could just add an OBDII WiFi wireless networking adapter? That way my car could automatically patch itself like my Windows PC does. :nana:

I took mine in on this past Friday to get the ECU reflashed. It was the first time I've gotten it flashed, and I bought it July 31. Personally, I love the reflash. Doesn't feel any slower, just a lot smoother.
