<u>Basic ECU Reset</u>

Operations Procedures:

1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” (NOT start) and wait 3 seconds.
2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.
2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
4. Fully release the accelerator pedal (while the CEL is still blinking)
5. Wait about 10 seconds.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.

I just unplug the negative terminal, press on the brakes 3 times and thats it. Some peeps leave it unplugged over night.

Or you can do the dance ^ above lol

 

Just finished installing the coupe mid-pipe and barely notice a sound difference.

 

What year is your sedan... 05-06 sedans won't have much of a difference.. its the 03-04 that really sound better with a CP middy.. but if u keep modding your exhaust, (eg. HFCs, muffler, Y pipe) it will really help out, i noticed mine when i swapped back to stock for a day..

 

05 sedan. What kind of HFCs, muffler and y pipe?

 

Your best route to better sound is probably in this order (some may argue): a higher-flow muffler such as 03/04 sedan or aftermarket like HKS, then HFCs then y-pipe. I am running the HR-Y, 05 sedan mid and HKS but recently had the Z-middy (same as coupe) and stock 03 muffler and it sounded pretty great.

Y pipe of your choice. Preferably oem 350z or 07 08 g35 sedan oem Y pipe but they're kinda hard to find. Go on ebay and type G35 y pipe or 350z y pipe and there are plenty to choose from, some more expensive than others. I bought my HR Y pipe used on ebay for 100 bucks

 

Again, 07/08 preferred.

 

If you'll add the HR y pipe and a z tube to your 05 with the coupe mid you'll definitely hear a difference. I had an HKS muffler for a while with the stock mid and CM on my 05 for a while and liked it but the drone was a deal breaker for me. Went back to HR y, z tube, intake, and the CM and really like the sound.

Much different from stock and very pleasing.

 

I would only get the 350z pipe, the g35 sedans HR Y has baffles.

 

^ i got the 08 sedan Y pipe. I love it and the baffles don't bother me since i have a straight midpipe and muffler without resonators it helps with the drone

 

Anybody got a sound clip from their exhaust?

 

My setup right now is : Berk HFCs, 370z HR Ypipe, CP Middy, HKS rear muffler, and fujita intake w/ motordyne plenum spacer...

Here are some clips of my exhaust.. :



forgive me on this clip, i shifted late into 3rd.. thats why it bounced a little off the rev limiterdoh:


in a few weeks i am changing my exhaust and getting rid of the Y pipe and cp middy, just a heads up if someone wants to buy it... im getting custom straight pipes made from the HFCs to the muffler... ill post up a clip when its all done and broken in...

 

^ that's gonna sound mad raspy with straight pipes from cats to muffler

 

^^ Agreed, sounds nice, you should leave it alone.
