Someone made the Tachometer work in the Subaru BRZ after installing a LS2 engine.

The Subaru uses a CAN BUS just like Nissan and the Tachometer gets its signal from the crankshaft sensor.

I wonder if it will work in the Z if someone machine the VQ timing ring into the 2JZGTE/LSX Flywheel and use the Z crankshaft sensor!!

Some people do the same thing when installing the VQ30DET.

 

That's what Z fever did when installing an SR20 into the Z as well. So you’re definitely on the right track.

 

Or try to bolt the AT 350Z flex plate timing ring to the flywheel and make a bracket to hold the VQ crank position sensor.

 

That's also another good way as well. See you have plenty of options that won't break the bank on an already expensive build.

 

The Z flywheel is way smaller than the LS but some stock LS motors come with a 60-2 (58x) reluctor on the crank shaft which could be used. You would have to split the crank signal to make it work though which could have some adverse affects on engine performance.

Not sure on a VG or 2J motor though.

 

The 2JZ flywheel is the exact same size as the VQ flywheel.

 

it requires more then just the crank sensor the stock tach works combining both the crank and at least one camshaft pos sensor. i can tell you for a fact with both cam sensors unhooked rpm will not registeron the tach or in the ecu, or even in a aftermarket ecu. at least for the vq pattern, also have to know the vq engines have a crazy *** cam/crank pattern which requires very specific hardware firmware to work. thats why its late to the game with aftermarket ecus, its not even close to anything

 

There is nothing in the 2007-2008 FSM that indicate the the ECU use the camshaft pos sensor to get the tach signal. It only says that it use the crankshaft pos sensor signal to send the tach signal.

 

fine go try it then lol the ecu cannot tell the phase of the engine without the camshaft pos sensor and thus wont output a rpm signal. why do you think none of the ls guys except cass are using a stock tach? and cass required a bunch of custom work to get it to work and it definitely wasnt just using the stock camshaft pos sensor with the vq reluctor wheel attached. theres a ton of **** the fsm is either wrong on or dosnt mention as ive pointed out several times in the past.

another example of someone with no firsthand knowledge telling someone with firsthand knowledge they are wrong.

 

Also contacted Hal about the custom Haltech 350z 2JZGTE unit. I'm waiting for him to respond to see if it works with the 2007+ Z.

If it's no go then I will consider getting the Sevecs S6 although it would be hard to fine a tuner that is familiar with this EMS.

But since Chris black from AMS usually flys to where I live to tune a lot of GTR's and EVO's I might get lucky and he will be here when I finish my car.

 

that would definitely be the route to go for you, the syvecs is definitely cheaper for you then us not sure on the tune though and i actually believe cass runs the syvecs mayby send him a message about what all he did for the stock tach i cant exactly remember i think he mentioned it somewhere around here though.

 

Cass is running the Vi-PEC EMS.

The Syvecs S6 with all the sensors and harnesses would be almost the same price as what Hal quoted me for the Haltech. The Haltech ECU manager is more friendly and I'm used to it and street tuned my 350z when I had it.

 

my bad couldnt remember either way i think he had to run some sort of converter box in conjunction to get it to work. in referance to your original comment though cant really compare the subarus to nissan though, yah they both run CAN systems but the signals they send over that system are completely different even the construction is different. engines are engines and all behave the same but electronics are proprietary usually to each car let alone different manufacturers(minus gm they love interchangeable parts and def a good business decision imo.)

i kinda figured that haltech would be alot more since its custom work, but hey if you can get it for the same price go for it haltech is still my favorite for entry level self tuning.(i might talk up the infinity and it is easy to use but first start up can be very very intimidating same for pro efi and i imagine syvecs.)
