I am so glad I don't have to deal with the factory ECU anymore and Ecutek.

Also since the secondary O2 sensors on the 370z are 1 volt sensors, I am not sure if its a great idea to try and use their input for a 5V sensor. Of course I have never tried it, but I don't know if ECUTEK makes it possible to turn those inputs into 5v or not. I would actually be curious. But perhaps this in itself is the issue you guys experienced trying to put a 5v pressure sensor on that secondary O2 input.

As for a car throwing MAP sensor codes when a coolant pressure sensor is on the MAP input, that must be either incorrect wiring or incorrect scaling in ECUTEK. Because a MAP sensor and a coolant pressure sensor are the same sensor when looking at aftermarket pressure sensors.

I have moved away from Ecutek. Done with that. I am so glad that I did.

Definitely no reason to look back. Just conversing about the possibilities of adding sensors with ECUTEK.

He is going to replace the MAP sensor. If it does like what happened to me when I replaced the O2 sensors it will be back. It's wired up like the GTR guys do for coolant pressure.

Well, the new MAP sensor didn't fix it. Three choices, to turn the codes off and fly blind, Remove the coolant pressure sensor, or go to an Emtron.

I have the following extra sensors hooked up that I can log. Ecutek can't handle all this. I had posted it previously.

Fuel Pressure
Oil Pressure
Coolant Pressure
4- IAT's 2 pre CAC and 2 close to the throttle bodies.
2- EMAP sensors
6- EGT sensors. 1 per cylinder in the exhaust manifolds.
The 2nd fuel pump is controlled by the Emtron. No more Hobs switch for me.
2- Bosch Motorsports lambda sensors
I had to add 2 extra boxes for all the additional sensors.
Custom Motorsport wiring harness for all the above.

You have to turn off all the codes for the maf, admin doesn’t have issues with it

Yeah, that would be a no go for me. This is exactly why I am on an Emtron.

He was throwing MAP codes. Not MAF codes.

This is very typical in the VQ community. You tell them why you are doing what you do and they won't believe you. They have to follow everybody else off the end of the pier. Ya'll have fun. I am just about done with all this nonsense.

We all look forward to hearing from you again in a few hours. :bowrofl:

If you want to find out how slow you are, go here. Slowest class is 189mph. If you can't run that you are not getting in to roll racing.

Good info.

The issue is definitely with the installer. We've sold over 20 kits that hijack the rear o2 for input and not a single one had issues or codes.

Ecutek is the way to go for 99% of builds, but most people don't know how to install things properly or tune it properly.

LOL

I am still enjoying my car. It is a ton of fun. Sorry I can't post any videos of me having fun. It's the times we live in. All it takes is one hater and you are done for. Maybe I will take it out somewhere this year so a few folks can see it in person. ZCON is just too long. I won't be going to that. Maybe I will go somewhere else. Right now, I am just enjoying it by myself. I built the car for me so that is really all that matters. I am so glad to have it back together and running like a rocket.

Watch this if you want to understand why.

I am afraid I am all too familiar with this. Somebody did something similar to my wife back in June of 2020. She has had false reports written on her, she had over $300,000 dollars of property stollen from her, she has been charged with a crime and put in jail, and we even had someone come to our house late one Friday night to do us harm. I caught the person before it went south and ran them off unknown to me at the time of who he was. We have gotten most of this taken care of except for the theft. The other stuff was dismissed. I have spent over $50,000 dollars in legal fees so far and we are not done yet. We are both tired, pissed off, and are still enduring an emotional rollercoaster. We both are not willing to give up and want to see it through to make sure justice is served. It's been hell the last 4 years.

This is normally what happens when I give someone a ride. They cry Uncle real quick. Mind you, My car is not this fast. We don't have the traction of an AWD car but we are 1000lbs lighter. My wife watched it with me and died laughing.

LOL, My buddy Brian did the exact same thing. He tapped out and didn't want me to turn it up anymore. LOL

I have lots of fun planned for this year. You never know where I may turn up.

It's nice and quite. Everyone is all over somebody else. Perfect, just the way I like it.

Nah, I don't think I will play the game.

hey spooler, maybe i missed it but, what are your intake temps looking like?

It took 5 back to back runs on the dyno to see a max of 111 deg in a 95 deg shop. My chit is right. Before, it was 158 to 168 deg on one dyno run. On the street it is dang low. I can see it on my Emtron display and I also log it.

LOL, too funny. Again!!! It's not for everybody.

Dang! Brother you got your stuff on point. Im going to rebuild the car next winter and going to do everything possible to lower temps, and back pressure as far as block goes havent made my mind yet. Also dont know if saving up for a syvecs ecu would even be worth it, but heard really good things on there gtr firmware. But thats awesome brother your z is a wepon.

My Emtron is working good. No issues.

If you want copper headgaskets make sure you do this. It will make your life much easier. You can try to short cut it but this is the proper way to do it.

I am not against it. But i was thinking maybe trying 14mm head studs and fire lock gasket. So i dont have to worry about sealing oil and coolant and re torquing the heads.
Maybe i start cheap and just do a basic 14mm head stud and open deck and see how far it takes me. I have a couple spare engines so i can try again. I think it may be better to start simple.

Listen to this. This has never been done for the VQ, step by step. There are things we can do to make the VQ last longer and make more whp. It's never been done with all the VQ shops we have. That's why I went to a standalone. No more guessing.

Hold up, how? When? I missed that when did you go emtron? Pnp kit? Custom harness? I have a billion questions.

Do not do 14mm headstuds. There is not enough meat in the block. Stay with stock size L1900 or ARP 625's. You can do a CSS block or go to Darton MID sleeves with a MLS headgasket. It depends on what you want to do. Street car, stick with a MLS. There are downsides to everything. You have to pick the best solution for you.

Yup, I am on a Emtron KV12. I will never go back to a factory ECU.

Yea i hear you. Shes more likely going to be full race car next year or year after. I have a turbo ls vtec 89 civic for stree or 94 300zxtt that i want to keep street dont want to start cutting up the 300zx to be a race car. So my 2017 370z will have to become the race car lol. But i hear you, there were people running the vq35 with 14mm studs that had good success, maybe im wrong in assuming it would work on vhr. I also wanted to add arp insert washers. Back in the day when 240sx ka24 were burning head gaskets around 70php some guys ran arp insert whashers to get better clamp apread and had succes getting past the 700hp mark.

Dam man im a little jealous lol. So u you were able to keep ac normal key fob and all normal dash functions? Pnp kit?
Hows the traction controll strategies? Im sure it has top notch traction control . How about boost? Time based boost controll? I would love a stand alone specially for boost and traction control. Getting a real launch controll system. Roughly how much did it cost if you dont mind me asking?

The only thing I lost was syncro rev match. I can heal toe so that's not a big deal. Everything else works. As far as traction control, I use none. LOL, I have it turned off right now. I am sure I will play with it eventually. I do have boost by gear and rpm. I can do both at the same time.

Cost, it wasn't cheap. I added a ton of sensors also and a Emtron 5 in. display. You can see it on the two videos I posted earlier in the thread. Page 361.

Page 366 for the additional sensors.
