Hi Sosonic, does your car run cooler, rev up higher before changing gears and generally feel more eager after the Re-Amemiya ECU re-mapping?

The rev limit is now higher, 8500rpm ++ but I do not know at what RPM it cuts off and my speed limiter of 180+km/h ( Mine is JDM model ) has been removed after the re-mapping

It was money well spent as I could definately see an improvement in the temperature ( about 5 degrees cooler for water and oil temp based on my Defi gauges and the centre console no longer feels hot like it used to )

I,m looking forward to the Pulley Mod once I am sure I will not face any cel or other issues.
Anyone else who has the AP Pulley on an Auto 8 please comment

 

I don't have temp gauge, yet (working on car navi/stereo upgrade), except for the stock. So I can't get exact reading on temp. On the re-amemiya paper that they give you, it shows that the ECU flash also turns the fans on sooner/at a lower temp to cool the engine. The car does run faster.

I have the same issues as you do about the Pulley mod. Cel and other issues concern me, I'm going to keep asking around and consult some local mechs about it. Its down to either Agency or Unorthodox, just want to be 95% comfortable with which I choose. But, its a kind of cheap mod (well least not the most expensive).

 

Do keep us updated if you do either pulley, I will do likewise & cheers to all who responded in this thread....

 

I really feel for you guys with 04/05 automatics who are still dreaming of making this car faster, cause I remember the struggle back when I had mine. By the way, if you want to launch past 2200 RPM, you can try putting the car into neutral, revving it up to the desired RPM you want to launch from, and then quickly shifting into drive (a neutral slam). Whenever I tried this I was never sure if it worked too well, plus it has the potential of causing some damage your torque converter. Then again, if you guys are trying to increase your rev limiters past 7500 these days, it's pretty clear that you don't care too much about the health of your tranny anyway. Good luck guys.

 

The high revs won't hurt the tranny as long as you take care of the extra heat. Won't hurt the TC either, it just won't be as efficient above 7500 (again take care of the heat). Neutral slams will hurt the tranny and possibly the rear end.

 

I'm pretty sure Re-Amemiya knows what they are doing when they raise the Rev- limit. When they re-mapped the ECU, they must have taken into account that with a higher Rev-limit, the tranny and other stuff will run hotter too. Those who had their ECU done by Amemiya will know that the car runs much cooler because the fan cuts in earlier to cool things up.

 

Yeah, neutral slams are a good way to force you to buy a new tranny way sooner than expected. Much more interested in customized torque converter... I want the car to consistently be able to handle high rev launches, without buying a new tranny every 6 months.

 

The low power renn uses a differn't e-shaft, main bearings (non multi window), and rotor bearings. Infact the bearings are identical to the ones for the 86-91 rx7's which had a maximum redline in the 89+ NA's of 8000 rpm. I wouldnt take that motor above 8500 rpm. The motor is not build to take 9000-9500 rpm like the high power.

 

I have installed a Agency Power crank pulley on my 04' Jdm Rx8 AT 2 weeks ago...

No CEL or any other negative issues...couldn't tell the difference in air-con temp either.

Power-wise, it revs noticeably faster from 3K onwards. That's all.

Faster revs = better acceleration.

 

Hi, I noticed that you are in Singapore too! Did you have the pulley upgrade done by a local workshop and how much did it cost you? In SGD...Singapore dollars so as not to confuse the others over in the states.....

 

I had the pulley installed by Monster Garage. The installation process was a breeze for them. Cost SGD30, but that was because I bought the Autoexe underbrace kit at the same time.

So far, after doing so many mods on my AT...the most effective one would be the Knight Sport Final Gear 4.777. I highly recommend installing the pulleys with this gear. Awesome results!

 

[QUOTE=sosonic]Off topic, but Re-amemiya has this cool test NOS kit project too. I don't know when that will be finished or if they are making it available yet.
[QUOTE]

Dont think they will manufacture it for the AT cause I have checked with them before.

 

Did you buy the AP pulley from them? Or did you bring it in from the USA and $$$$ ???
Thanks

 

Nice and thanks for the info. Feel a little better about the Agency Power Pulley, but anybody else feel free to tell their stories about it. Would be nice to see a Dyno number of the Agency Pulley too.

I'm still on pause mode, since I'm seeing what type of numbers these new super chargers (Axial Flow and Hymee) will put out and how much they cost. Also, I'm studying on the customized torque converter issue and seeing what kind of price and HP numbers I could get. If the SC or torque converter is some crazy price or the numbers are not to my liking than I will go with Agency Pulley and MS/AEM or RB Cold Air Intake, and save up (eventually going SC and/or customized torque converter later on).

The customized torque converter still intrigues me very much, as I'm hearing you can get a decent HP gain and performance from it. Maybe 20 HP. Torque converter, Pulley, and CAI might give some really decent performance and HP numbers for an NA RX-8. Want to compare that with the price and HP numbers for the new superchargers and then decide.

 

a custom tourque converter is an interesting idea. so the point of it is that it idles higher so that you are already at a higher rpm when you go?

would this mean that you would get noticably worse gas milage? or is there some way that it can be shut off and on?

 

Not really.

The stall speed of a converter determines what rpm the car will take off at (when you floor it from a stop). If the car does not have enough power, you'll not reach stall speed without brake boosting. There are actually 2 stall speeds, but I'd rather refer you here: http://auto.howstuffworks.com/torque-converter.htm ; than mangle the explanation.

I'm not 100% sure what the stall on the 8's converter is, but by all accounts the tranny is from the FD, so makes me wonder if the FD's converter is the same as ours. In which case, upgrades should be easy to find.

Edit: turns out HSW doesn't really explain stall speed, but I can't remember where I saw a good explanation.

 

oh well. if the converter is the same as the FDs than that would be awesome and give us many more options.

has anyone even looked into this?

 

I thought it WAS the same torque converter. Can't remember where I read this, unfortunately. Same tranny, same converter to save money.

 

Could the interceptor-X be used to raise the rev limit also? Getting it with the pulley, intake, along with other "simple" bolt on and getting it tuned seems like the best bet.

I have the a 2006 6spd auto though with the sports package and would love to rev it just a bit higher and faster.

 

I'm in the Dallas, TX area, anyone know where I can get my ecu reflashed and rev limit cut in this area? Are you guys having to send off your ecu to be reflashed? How much does it cost to do this? How long is the downtime to get it done? I've searched and the only info I can come up with is it's possible to cut the rev limit, I can't find out who will do it, is there somewhere to go that's better than others? I need help. I want it done but I can't find out anything on where and how. If you have any info that would be awesome.

 

I talked to mazsport and you could use an interceptor-x to increase your rev limit along with all the other goodies it can do however it cost $1500 which is a lot more then a rev limit cut ecu reflash. The other posters said they sent their ECU to RE-Amemyia which is in Japan as far as i know. you could be without an ECU for up to couple of weeks depending on your shipping methods, how much is 1-2 day global to japan? lol. Also their products are are pretty high, so along with the shipping cost dont know what the total cost is. If one of the guys could post how much it all cost that would be awesome.

 

The price of the re-map is 50,400 YEN? which is US$424?
Just guessing since i dont understand japanese

Hey fellow AT 8 owners. Ok I was looking at this thread and I see that people took off the speed limiter. The max mine goes is 125mph because of the speed limiter. Is there a way to get rid of the limiter without taking off the rev limiter? I dont have the money right now to replace the tranny so I dont want to mess with its rev limit at this time. But I always race and I know my car can go way past the 125mph limit. Any ideas?

 

Well, it could be done.. I just don't know how.. lol..

 

I have heard of some companies that can do it, there is a chip that modifies it but it takes of the rev limiter as well. All in all if I have to rob from peter to pay paul then so be it. I would just rather not.
