Hi, 2018 was the last time ive been on Mazdas247, so it's kind of cool to come back! However, I do have a question. Ive got a log of me doing a 3rd to 4th gear WOT pull, once i shift into 4th the car bogs down. If i were to guess, id say my TPS/throttle body is on its way out. While im at...

Hi, I just got a new Windows 10 computer, did nothing to it beside install the R4 Software. I've got the correct USB to Serial adaptor, I've made sure the COM ports are the same. I've set the engine and system settings. However, when I go to Connect to the ECU, it attempts to connect for a...

2 Questions. Can somebody show me a Stock AF Chart for a Speed protege? And my other question, so I ordered a PSC1-020 without R4 software. I get my package and I see a white disk talking about the R4 software and think "did I get it by mistake?" I put it in my computer and stuff and it looks...

Looking for a Yellow Mazdaspeed protege. Live hour south of Erie, 2 hours north of Pittsburgh. Willing to travel up to 4 hours away. Ok if it has R-title as long as it's aloud in PA. Would want one with Lowish miles and not a lot of mods. Cash in hand.

Ok, so I just got an RX8 and was told it's flooded. Kid ran it out of gas, put gas in it and didnt cycle the fuel pump. Also says the motor had good compresson. So I'm trying to deflood it after awhile of trying I start to let off the gas slowly and see if it'll try to start, but I have the gas...

It'll need new headlights, bumper cover, hood, frame will need pulled alil back towards the driver...

So my intercooler and intake hard pipes keep blowing apart. What do you guys do to keep these things from blowing apart? I have weapon R hard pipes. I can't seem to get them to stop blowing apart. My cars stock boost too. What do you guys use, what couplings do you use. The clamps I use are like...

Ok, so as the title says. Is that possible?

Hi, I made a thread probably 2 years ago on here for LED bulbs for my speedo/Rpms etc.. And I can't find it. Does anybody know where I could buy LED bulbs for the MSP cluster? Thanks.

No I don't plan on putting one on. I'm just wondering if there's anybody on here that's put one on there car. From what I read it seems like you have to have decent boost. But I'm not sure, I just read about them today.

So when I got my car the vacuum was ~20-22. Then I had to take my car to a Mazda Dealer and when I got my car back, my vacuum is now at ~10-12. Can anybody explain this to me?

Ok, so my car has a miss fire. During the warmer months it would hardly miss. But now that it's colder it does it every time I drive it. I get why it would while cold cause the air is more dense allowing the car to make more power. I had a sputter and I replaced the plugs, wires, and coils...

Hi, so my MSPs miles are getting up there. I'd like to replace it with a lower miles motor. Does anybody know websites that have complete motors? Turbo included. Tranny doesn't need to be.

So I have new WeaponR hot pipe and cold pipe. And a corksport exhaust. My boost controller is turned all the way down. And my car still wants to boost to 15 psi! When I'm driving normal it goes between 7-9 psi. But say I went to pass somebody in 4th it goes to 10-15! Like I said my boost...

Like the title says, can anybody give me some recommendations for a nice sounding BPV that would add some style too?

Hi I have just a quick simple question. I know diesels have a turbo silencer ring. But do cars have these too? Like a silencer type of part before the MAF or?

Does anybody know where I could get good "performance" ignition coils for a MSP? I got some from autozone and they aren't working out at all.. I've had a stutter for like a year and a half and I've been trying to figure out what's been going on and I've been using Autozone coils/plugs/wires and...

Hey guys. I know this might be hard to figure out so this is more aimed to Mazda mechanics I guess. But my car under a load at like 3500 or 4000 seems like it misses. The check engine is on, but only says its an EVAP. There isn't other codes. I changed the coils and it's still doing it. the...

So I've looked on YouTube and searched on google on how to install vertical doors. I find things on how to install them. But I wanna see some installed on a Mazda protege (MSP). So can somebody help me out? Typing the instructions out might take to much time so a movie would be ok. Unless you'd...

Does anybody know where I could get performance fuel injectors? And have any recommendations of which ones are good ones.
