Question about MS Performance

[MazdaSpeed0020]

I recently bought the MS, it has 800 miles on it right now, after about 700 I gave chase to a few mustangs around town, when I was in second gear I felt the turbo start to kick in, but then in the same gear it felt like it stopped spoolin, then around 5500 rpm kicked back in again. What could be causing this problem. I took a friend of mine for a ride and he doesnt think that the car is even running at 6 psi. I need some help quick, I would love to fix this problem with out having to drive an hour to get to the nearest MazdaSpeed dealer.

Also I have been searching for parts, but damn whenever I do a search there are huge amounts of post, so If anyone has any shop that sells an a-pillar dual gauge pod that would be most helpful too.

s*** sorry guys, I posted in the wrong forum, moderator, could you move this post to the MazdaSpeed forum please.

 

[dominoy2k1]

thats the dreaded hesitation most speeds have....you should get joes fpr kit and fuel cut defenser.....it is supposed to help out with that problem...

 

[dominoy2k1]

yeah forgot go to joepmbc.com .....

Ok I am going to ask another question that has probably been answered, but what really causes it to start spooling and then die off and spool again, is it just a simple fuel problem?

Matt

Thanks for the help.

 

[boostisgood]

Its not the turbo spooling then stopping then starting again. The MSP is notorious for running VERY VERY rich on Open loop (that is when the computer ignores the sensors and runs off a preset fuel/timing map)

A turbo, unless you have a bad wastegate, would not spool, stop spinning, then spool again. the exhaust gasses are passing through it, thus turning the snail.

 

[MazdaSpeed0020]

So being that the car runs very very rich it causes it to feel as if the turbo was doing something like that? Man if this is the problem, which I am sure it is because I have heard about many others with it, I really need to buy some Joe P stuff. Thanks boost, if you have any more info that goes further into this problem please post, or maybe a link to one of the many threads on here that talks about it.

Do a search, I have been dealing with Mazda directly, about this issue. They have assured me that a fix is in the works. There are several threads about it. just search it out.

I rarely experience this hesitation issue, but the few times that I have I simply let go of the gas for a very short split second and push back down at partial throttle. As the speed increases I increase pressure on the throttle and always get a clean straight pull to redline. I never get as clean a pull when the pedal is all the way to the floor. You just have to get more familiar with your carwhich will happen as you drive it more.

And search the "Mazda Does Care" thread which has a letter from Mazda USA regarding the issue.

 

[MazdaSpeed0020]

I am familiar with the car, I have only driven Mazdas, so I know how to drive this car well. But you shouldnt have to let off the gas at any point and the steadily apply it to get a good pull through the rpm range. That seems like bulls*** to me, but from what I have read about this whole issue it seems like the Joe P products will fix this problem right up.

I dont' think he was trying to say that you don't know how to drive Mazdas....he was just saying that it seems like a lot of the MSPs have been experiencing different driving characteristics, and once you learn how this turbo interacts with your specific MSP you will learn how to drive with the hesitation. That being said, no youshouldn't have to let off the gas at any point, and I really feel for you, cause it seems (from the other thread I read) that I have one of the more pronounced examples of the hesitation and it sucks. I also love my MSP and am (kinda) patiently waiting for Mazda to come through with something (at least for now). And just a word of caution (disclaimer), if JoeP doesn't chime in, his products were made to POSSIBLY help people with the hesitation...I haven't heard anyone dissatisfied with the FPR kit, but even he says it is not inteneded to be a "fix" for the hesitation....it'll probably take the edge off though (and others it does seem to "fix" the problem).

Just wanted to share with you what I've been researching and reading. At any point, good luck, and PLEASE bring your MSP to the dealer and make them aware of your hesitation and make them address it...this way we have another documented case of the hesitation with Mazda.

Peace,
Jesse

Well said OrangeAppeal, that's exactly what I meant.

As you drive your car more and experience the hesitation, you'll find ways around it that work for you specifically. For me, getting off the gas slightly of a split second is enough to tide me over till Mazda comes out with the fix in the next 30-90 days. If however, you've got the extra cash around then get Joe's stuff. No one who has purchased it has said anything negative.

I had the hesitation up until about 1 week ago...then I installed the INJEN intake and reset the ECU. I haven't had it since...however, I do still get the stumble (hard accelerating and then let off the gas to slow down or slow-shift), which makes for a fun bucking bronco ride. I think this may be a problem with my DV (bypass valve) causing surging. I'll be fixing this issue fairly soon by replacing it with a different DV...one that doesn't sound like a turkey(<--- my primary motivation).

Now...I can't say 100% that the INJEN will fix the hesitation (and it ain't cheap either!) so follow OrangeAppeal's advice and talk to your dealer about it. Tell him you know how it happens, and why it happens, and that it happens to MOST MSPs. The more we tell MUSA the more likely they'll be to get a fix done for us.

Welcome to the not so wonderful world of hesitation!

 

[TampaBlackMSP]

So far with my mods (just put the fpr on last night) the hesitation is gone (knocking serious wood here!) - so far so good...

 

[MazdaSpeed0020]

Thanks for all your help guys, I did talk to my dealer and let him know about my problem, told him there are many other MSP that are having this problem and he is looking into it for me. I would really like to buy the Injen intake, but I am not exactly sure if it will void the warranty or not. Plus I would like to get Joe P's products to see if this problem is fixed, but I will wait until I hear from the dealer.

hesitation sucks, i just ordered my FPR kit, to help lean it out until i get engine management in the next year or so. Then, it wont be a problem at all..
god i want forged internals, and engine management.

Waiting for the dealer is like waiting for a woman to make up her mind. Forget about it. Go to www.joepmbc.com order the $45 MBC and the $20 FP Reducer and you will never have the problem again, and by the way 50 extra horsepower ain't a bad start either!

 

[Aaron]

i just reset my ecu and the problem is gone sofar after 24 hours....

 

[MazdaSpeed0020]

I will probably get the stuff from Joe P, but I also want the Injen too. Wesman, what are you talking about 50 extra horsepower?
