I was looking at the performance chips and the intakes to try and boost off the line performance.
I have a 91 RX7 vert.
Does anyone think that any of there products will work???

 

Only these: http://www.autodirectsave.com/produc...ce_Light_Sound

But.. no.. most of the crap on that site is bogus..

If you want a "performance chip" get a standalone ECU or SAFC.

 

http://www.autodirectsave.com/produc...formance_Chips

the specific site he's talking about. BTW the standalone replaces the stock ECU but it might be overkill on an NA that is not heavily modified. You're better off with an SAFC (fuel controller) in order to squeeze as much power as you can. Try to keep everything in one thread instead of splitting it off into two threads about the same subject.

You are starting off with the heaviest FC so you can also look into removing as much weight as possible (which honestly won't be much unless you go hardcore and remove a lot of things.)

 

Where do I get a good SAFC (fuel controller). Will this help with off the line peformance. I already have the Racing Beat True Dual exhaust system. Dont you think that a computer chip will increase performance or will it mess up the car
please direct me im confused

 

overkill for an NA? Bahh.. you suck phoenix.

Here's a "chip" upgrade:
http://www.pocketlogger.com/index.php?pid=rtek7

Great product.. direct replacement for stock ECU. (easy to install). Also. the new stage 2 one has updated fuel stuff.. like bigger injectors are possible...adjustable timing maps, user correctable fuel maps and a ton of other stuff... I'm gonna get one for sure.

 

... the easy way is the wrong way, unless you are going turbo.

go read up about a afc neo, or PM a couple of gurus here, they are usually nice enough to help, in my case atleast..

you got a good exhaust system, thats a jump already, if you arent "fabrication" incline, then stick with the stock intake system, but get a better filter, i believe racingbeat has them and k&n.

you can consider losing some weight in every way possible. does your ac work and do you need it... does you ps leak, do you need it? is everything working good on your car, the car has to be in good shape, rotaries doesn't like the lack to tlc. it needs a LOT of tlc.

was the car tuned up? all sensors are in good working order?

please dont fall for the "chip for 10 hp" mods. after you have accomplished all of the things mentioned, get a afc neo (about 350-375 shipped) and a wideband o2, and work with it... make sure you 6pt is working, or.. its quite a lack of bang for the buck.

edit, wow i didnt know too much about the rtek i always thought it was for the s4t2 only, but i have the neo already.. i guess thats something on my consideration list for christmas, and sell my neo later on

Car is tuned and runs great I just want more off the line performance where do I get a good afc neo and a good wideband o2.
What do you think about the chip that michahelli mentioned It looks pretty good

 

look, I dislike the fact that you keep going on and on about "off the line performance" because you're not going to find what you're looking for with an RX7. These cars have low low-end torque (which isn't helpful for off the line) and if you WANT to take off like a domestic you will be sorely disappointed. SO my first request from you is to realize that you cannot gain low-end torque as easy as you would with a high displacement car.

^^^^There is a link to a store that has the NEWEST version of the FUEL controller from APEX-i for ~$300

As far as I know there are NO CHIPS available from our car in the U.S. EXCEPT FOR THE RTEK which I have heard good things about but am not too familiar with (they don't have them for my TII and i'm not adding it to my NA because I don't need it)

I know knightsports and RE-amemiya have chips and ECUs tuned for certain modifications but they are expensive and sometimes more dangerous due to fuel maps for specific modifications.

Micaheli: A Standalone IS overkill on an NA that isn't highly modified.

 

although if he wants a better launch a beefier clutch and LSD would help

 

Whats wrong with overkill....

 

well it's all in the word. OVER kill. why would you waste ammo on a corpse? same with the NA. Why waste a perfectly good 1200 bux when you won't GAIN THAT much more power.

The SAFC will be more than enough to tune the stock injectors (which by themselves are more than enough fuel for the 13B). maybe you can mess with the timing and spark and all that good stuff to get better reliability and squeeze a tad more power with a standalone but it's not really something that NEEDS to be done, especially in an NA with bolt-ons. Spend that cash on suspension.

 

^^ Somebody is cranky today.....

 

lol, not at all, I don't know why you'd think that today. I'm actually fairly content. Doing work, reading the forum, learning a tad about EGTs, about to go to lunch.

 

Sorry Phoenix, I have to agree with Mic^^. An N/A may not gain as much as Tii from a stand alone, but with Int., Ext., gearing, etc it can mean as much 180hp and 190hp. And while 10 HP doesn't seem like much, it can be a big difference at the track because the power is put where you want it. Its the difference of pulling even with the leader on thefront straight but not having enough to pull ahead, or pulling even and inching ahead(even with out my fav. ITBs, but thats a dead horse)

 

If you are going to pay that much for an AFC neo get the Rtek (the pocket logger link) it will give you so much more tunableity than the neo for not alot more $$$

I have 91 verts at the moment. IF i were keeping the n/a i would get the rtek for it. The vert is a very fun car to drive, in the twistys, but it really isn't quick. Even with alot of mods you wont get much more then about 200 rwhp.

 

Oh and the racingbeat exhaust is about the best start you can make. Check out there site, I thought about getting the headers from there but got a turbo vert before i did.

Also, check your 5/6th port system and make sure it works. That and the VDI, if they aren't working then you will be even slower.

 

You are right to an extent, I am only stating that it seems like overkill when you look at the power to money spent ratio, especially on an NA that hasn't had a lot of work done to it.

I have never dealt with the Rtek so I can't say much about it.

 

last I checked R-tek had nothing for S5 NA's
if you're going standalone on a NA I wouldn't spend anymore than what a Megasquirt setup costs

I wish the OP (and the thousands like him that post) would fill us in on their expectations of the car and what they wanna do with it.
Hard to give any decent help with so little info

 

^Agreed

wow, I had forgotten why I was waiting for the Rtek to come out for the S5 TII.

 

I have an Rtek, my advice when you buy the Rtek?

Buy an early model Palm. They work better with the software. I was having problems with my Tungsten T. Thankfully, my friend has a case full of used old Pams and he was gracious enough to give me an m105.

 

I have a question. for the rtek 7 stage 2. does it still require you to have the AFM if your an S4 NA. Would if pass smog without the smog person knowing about it.

 

Yes. it requires the stock AFM. Would probably pass smog if you had it tuned correctly. Visually, its in the same stock ECU box, so it shouldn't look out of the norm. You would want the ITS mod though to make it visually identical to stock ECU.

Thats how I understand it anyways.

 

ITS mod is only for S5, AFAIK
