Ordered a M370 Mani and throttles. When they get here will install them on the car and head to the dyno for a retune. We shall see...

I guess I can follow you here also , LOL Keeps us posted , He's doing a stock mani port and polish for me and I'm testing it against my M370.

Just sent my stock manifold off to Scott, I took stock pics and will be comparing the ported Stock Vs the Stock manifold and also VS the M370

So you send your m370 in for porting?

Actually he paid me to buy one for him, we'll port it and send it to him and give him his money back when we get his back. This way his car will never be down.

Nice...i have a m370 already. ll be waiting for result

I'm not sure if he's going to do a ported before after so just a fyi. The results might not mean anything as his dyno could read high or low. Yes I know we need to do this for people. I'll ask a buddy with my TB's and a m370 and see if he'll let me port it out.

You are correct Scott. Just jumping on the dyno to see if the combo makes any power or torque compared to my old dyno runs .

I wanted to bring up an important issue that I was recently made aware of. Like the comment I made in this thread about how you need to insure and properly package your return items, I want to keep all communication open about anything that pops up and I need to make you all aware of.

Recently I sold a throttle body set to a customer in Australia. After installation the customer was throwing two CEL's. A P0123 and P0233. Both are throttle body TPS sensor codes. After the customer troubleshot a few things and did the throttle body reset procedure a few times, it was determined that the TPS sensor was bad on the passenger-side throttle body. All the customer did was remove the four screws holding the black TPS housing to the throttle body and swap his OEM TPS sensor that clearly had been working. I've been told by a few people now these electronic TPS sensors are very sensitive to vibration and bouncing around. With shipping these throttle bodies from customers to me, to the porter, back to a new customer it's possible these will go bad. If by chance you ever get one of my ported throttle bodies that is throwing check engine lights with these codes or possibly any other TPS sensor code, it is okay to remove the four screws on the TPS sensor housing and just swap the covers.

Below is a pic of what I'm talking about. As you can see it's about as easy as changing a light bulb. I say about as easy because the screws have an antitheft torque screw. In removing the cover below from a broken housing I got back, (posted before) all I used was a pair of needle nose pliers. The screws are not that tight nor difficult to remove.

Any questions please feel free to ask.

Fyi, here is the TB reset procedure.

How to reset your ECU and perform the Throttle Pedal Release and Idle Air Volume Learning procedures on an Infiniti G35 and the Nissan 350Z.

Before attempting any of the following procedures, it is advisable that you read through the instructions thoroughly and familiarize yourself with them.

A stop watch or an analog clock with a second’s needle will be useful.
**a quick reset can be accomplished by disconnecting the negative battery terminal, and depressing the brake a few times.

ECU Resetting Procedures

Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON.

Operations Procedures

1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” 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 second.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).
8. Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.
If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.

Accelerator Pedal Release Position Learning
Operation Procedure

1. Make sure that the accelerator pedal is fully released.
2. Turn ignition switch “ON” and wait at least 2 seconds.
3. Turn ignition switch “OFF” wait at least 10 seconds.
4. Turn ignition switch “ON” and wait at least 2 seconds.
5. Turn ignition switch “OFF” wait at least 10 seconds.

Throttle Valve Closed Position Learning
Operation Procedures

1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch to “ON”.
3. Turn ignition switch to “OFF” wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound.

Idle Air Volume Learning (Throttle Position Learning)

It is better to count the time accurately with a clock.

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Confirm that the accelerator pedal is fully released, then turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.

My intake manifold was delivered to Scott and Stewart signed for it :)

Nice porting work, I've done some P&P on my last project cars TB and gasket matching the upper and lower intakes. The thread is so long I didn't read every post to see what you charge, which you've probably covered a few times. So I'll ask, what do you charge for the uppers, lowers and TB's?

Thx
Greg

I am still waiting. Need to get this done ASAP.. Some progress pics would be nice.:tup:

thanks

all the selling and info like that is here to keep it sparate from the discussion...http://www.the370z.com/exhaust-intak...composite.html

mani's all box up. she's on the way.

Great Thank you

Music to my ears..

Well..... Received the manifold and NO throttle bodies.. I guess no dyno this week!!

Mani looks good though!!

U alive Scott? Please answer pm.

Lol alive but I work 3rd so I sleep at "5:39am." I PM'd you at myG were all our emails are.

Has your P0507 code come back. Mine is idling right around a 1000 RPM and I cannot get it to go away unless I clear it with my OBII. Will up rev take care of this? Any suggestions would be nice..

You have no codes but a higher than normal idle?

It does throw the P0507 code.

You can change the idle target within UpRev. But if the higher idle is due solely to the fact that something physical was changed in the TB then I don't know how much it'll help. I assume you tried the TB relearn?

Now that I think about it my tuner might have just turned that code off. My turbo tune idles about 950 cuz that's where the system is most happy with all the changes.

Maybe someone with UpRev tuning experience will jump in and provide more detail on turning that code off.

Those look to be air leak problems. All your connections tight? Gaskets all installed on the manifold?

He shouldn't have to do all that, no ones done it yet. The relearn needs to be done and all vacuum hoses and gaskets checked.

Hey Scott Pm'd you on G37, looks like it wont be here today :/ .

PM'd

Thanx Scott

No P0507 and my idle is fine after the TB relearn. However when cold starting it revs higher than stock before getting down to the idle and I have had a few P0300 (Random/Multiple Cylinder Misfire Detected) thrown at cold startup. I just clear the code via Dash Command and Kiwi PLX.
I have not touched my UpRev tune since the TB install and my gas mileage is a little worse (closed loop adding more gas to compensate for more air??). I also have M370 installed and I can't decide if I should send it or my OEM IM to Scott to port.

I wonder if the UpRev re-tune will fix the gas milage and idle a bit? My gas milage has already recently taken a hit after installing my momentum headers + motordyne ART pipes and I have the ported throttle bodies on their way back today hopefully as per Scott. Curious to see where this ends up in terms of power. So was the P0300 code just a problem at first, and has subsided since then DR_?

The P0300 is still a problem. It happens once every 10 times I cold start the car. I never get it except then.
I felt a modest gain when I installed my ported TB, similar to when I installed my M370 or when I installed pulleys. I suspect about a 5whp but I have no proof and I haven't done a retune.

My mani arrived this morning will be checking it out tonight when I get home, Pics will be posted.

Hey Scott.. Can u shoot me a pm with your # to help me figure something out?

Thanks

Blaine

Does anyone know the correct torque specs for all 8 bolts on the plenum??

14 ft-lbs. EM-34 and 35 in the service manual, there is a torque order that should be followed.

hmmm, most common being air leaks and neverbonestock just PMing me saying he found one on the mani, are all the gaskets on the TB's and upper to lower ok? also was it you and I talking about plugs? how many miles on yours and check the gaps. but since youre talking cold start ups i have to side with leaks again. after that depending on miles id look into fuel pump and the sock and injector cleaning.

Here are some pics of the ported mani Waiting for the others.

Scott,

Do u have a lower intake available?
