You do not need a re tune for a map sensor. This is a very interesting post, but really to me I rather buy everything I can to make sure the car is safe to run at the desired level. Also another reason the forum is here is to exchange information to help one another and further our knowledge with this type of vehicle. I dont know where I would be without this forum.

 

I will need (and have time) to make one more purchase before packing everything up and driving the 3-4 hours for the install on the 16th. I had initially ordered most of my parts from rx7store.net back in November but still haven't recieved all the products I paid for (DO NOT ORDER FROM THEM!!) and am less than satisfied...

Getting a refund and re-ordering parts from rx7.com since I have had good experiences with them. I was not aware that Banzai sold these as well. I take it the harness/MAP sensor are the same from both Banzai and rx7.com?? I want to keep everything together since I am now cutting it so close time wise..

 

Having the 3Bar can't HURT, let's put it that way. But I think we can all agree on one thing:

If you aren't properly tuned for the respective boost - you're done.

 

Ours is a plug and play harness, the other is just a connector shell and 3 pins that you have to crimp together and assemble yourself. http://www.banzai-racing.com/product...er_harness.htm

 

You posted a link to a 4 yo thread that made a claim and had a link to a vid that does not exist.. this is pretty weak ground you are standing on. Where is the data?

Considering there are no specs for the car besides stock port/stock twins @ 17 psi, I am to assume that this is a completely stock car with nitto drags and a boost controller? =400HP+ Seems everyone has been wasting a lot of money on all the other bolt ons

People used to go through a lot more engines trying to sqeeze every ounce of HP out of their cars without the proper mods as well.

Thank goodness we have advanced beyond the FCD, S-AFC and additional injector controller so we can now produce reliable hp with the correct modifications and control systems.

 

lol, ok. Yea, JD was lying. He never made those numbers or used any of that stuff. It was similar to the faking of the moon landing...



So, what does Nitto drags have to do with dyno numbers? So, I suppose you don't know how to use the forum and use the search.. Here's his thread:

I've been around for a long time, and IMO it's the opposite. People spend a lot more money today and get less out of them. I see people with mild mods, good PFC tunes barely making the same amount of power that the rechipped ECU's provide. Yet, those are also the same ones looking for a rebuilder within a few months.

Back in the day, I believe people took a more scientific approach to modding the car. I would assume part of the reason was the available of options also played a roll in it, but I see far too many people just go out and buy crap for their cars today and blow them up tomorrow. Stuff like that was not happening in the past. They were doing a LOT more with a LOT less, and doing it better.

 

really? I don't think much has changed...noobs still cut corners and pop their engines, but if anything, with the increased knowledge base and reputable tuners out there, those who WANT to do the job the right have the resources to do it, which should result in fewer engine failures

bullshit

 

Call it what you want, but it's my opinion and not anyone else's.

 

ok ok break it up and go to your corners!

 

I think with the proliferation of water/meth injection, that can't really be said anymore

Good to see a 3rd Gen section heated debate that I'm not knee-deep in

 

There is no debate. The stock map sensor can be used for 17 PSI. Fact, end of story. Whether or not people "think" it's safe is up to the individual, just like injector duty cycles. Period.

 

you could likely jack up a 3 ton truck with a 2 ton jack and stick your head under it, too, the question is, why would you?

the plain fact is the 2 bar sensor is rated/calibrated/designed for 1 bar gauge pressure, PERIOD, END OF STORY...now, can you push it a bit beyond that and get away with it? most of the time, sure, but for the cost involved, you're stupid to do so

now, let's take a poll of the best FD tuners on this forum and ask them if they use and recommend the stock sensor at 17 psi....anyone care to guess what the results of that poll would be? you lose

let's face it, mahjik, your car has been sitting in your garage for about three years now and you're obviously short on cash, but recommending other people cut corners because you choose to do it, or because your buddies from five years ago got away with it doesn't hold any water

 

common rich!! throw a kidney shot in.. we know you want too :-)

im suprised this got into such a debate as it did!

 

i think somebody needs to go apply some pressure to their stock map sensor and read the voltage to actually see if it reads up to 17psi. i'm not buyin' it.

 

it might work ok if you live in Montana

 

Ok, the stock twin turbos were designed for 10 PSI. How many people use the stock twins over 10 PSI? You would make a terrible lawyer.

IMO, there is no win/loss with that. I never said it was "recommended", I said was "possible" and it is.

Once again Mark, you keep displaying why you have had so many different accounts here. You bring up things which have absolutely nothing to do with the conversion only to make yourself feel better.

As far as my car, yes it's been in the garage for a while. While I have issues, money is not one of them.

Here the project I had done last year in my backyard (a more completed picture attached):

Heck, I was looking to buy an Elise as a 4th car. Money is not a problem that I have. I don't have David Haynes or Jimlab money, but I'm not starving. To be honest, there is nothing I need to "buy" to make my car drivable. I just need to finish it. However, there are a few reasons why it's where it's at:

1. I like to do everything myself. I'm definitely not the fastest and there are plenty of people around who are much handier than I am with a wrench. I have a friend who owns a garage. He has offered to come take the car and the rest of the stuff, then bring it back to me in a week or so completed; for free.
2. Time. I have a real job thank you. I also reevaluated my priorities a few years ago and I make sure to put my family first. If the choice between working on my car or playing with my daughter, my daughter comes first right now.
3. Medical/health issues.

Probably the main reason is that I just don't care. My M3 is my daily driver and it also does just fine on the track. If I had something like an older Accord or something as my daily driver, I would probably have more of a hunger to get the RX7 going, but that's not the case.

So, now let me put my eWallet back up. Mark, you never change. If you can't be right in a discussion, you use falsified personal attacks to disguise that fact. All it does is demonstrate how truly immature you are rather than assist you in getting your point across.

 

I think CW has already dont that. Everything I've ever seen from him says the stock map sensor reads at 17.5psi right below 5volts.

 

please do, I wasn't impressed

true, I'm just right, every time

you've already been shown the door here, mahjik, now you're acting like a kid and posting pics of your house LOL

you started in the the personal swipe, so your rebuke falls on deaf ears

all this coming from the guy who feels the need to post pics of his house a la Jim Labreck to show how much money he has? LOL

at the end of the day, you're still wrong: running the stock sensor at 17 psi is foolish

 

Well, you claimed I was broke. So, once again, you have been "shown the door" as you so put it. Either way, it had no bearing on the conversation topic at all.

 

I never said you were broke...twisting what I said once again, typical stuff

 

Ok, I'll rephrase it then, "short on cash". Either way, it's still a complete shot in the dark which is as usual from you; not even close. Still, not relevant at all to the topic at hand.

 

I've only read the past few posts and here is my thoughts. You should NOT run more then 14.5psi on the stock map sensor. There is ALOT more ways to calculate correct PSI levels too, Maybe that 17psi is really only 15 according to elevation levels. I don't know. BUT,... a funny thing happened the other day which can relate to this thread. I was driving crazy, like usual around blackwood ( smoking every big headed mustang) and the vac line came off and I boosted up to 22psi. Luckily for my added safety my 3 bar map sensor is made for that no problem, and my trusty 13b had no problems.

 

The 3-bar had nothing to do with you not blowing your engine, unless you were tuned to 22 PSI. Regardless of the sensor, if you creep or spike to a boost level which you aren't tuned for, then you run the risk of detonation.
