dandy, there is a wideband output. it is one of the wires on the harness that i have not hooked up with.

alex-do you have a pinout for me yet?

 

That's why I want to make sure the DET is the same sensors... because they will be obligated to support the DET since it is already listed in the application list. Therefore as long as the DET is fixed, the DE should work.

 

Ok.. I'll have to look at the zt-2 again.. it's been a few weeks since I've used it.

Also, I will post a pinout up tonight along with the cam/crank signals. I started one last week but just need to finish it up.

 

I think its the blue wire. if you need the installation directions, i think i have them in pdf format somewhere.

 

Ok thanks, I'll let you know if I need them but I'm sure I have them at home too.. probably just in a pile of stuff on my desk.

 

Greddy's latest....

 

When you get the UE, I'll have it.

 

Who are you talking to at Greddy Alex? I can send them the waveforms, I already have them... Sharif was talking to Kenji last but I'll probably call him on Monday myself to get this ball rolling.

Speaking of waveforms... here's the cam signal:



Crank signal - it actually looked more square on a different scope tonight than last night. Interesting:






And here's a pinout for the 4th gen. Handwritten quickly, nothing too fancy but it's clear enough to read.

 

well as long as Greddy is helping you out with the Firmware, I think it will be resolved...Like the Z guys had to, this will be resolved..I'm ordering mine soon

info@greddy.com....I'm assuming the person replying is just somebody in the US office that doesn't know much.

Kenji is the man you need to be talking too...Sharif is your best connection to making this happen.

The VQ30 crank signal looks a hell of a lot simpler then the VQ35 signals, so it's just a matter of getting someone to give us the time of day...not holding my breath.

 

Since whoever it is seems to be replying, do you mind if I send them your waveforms while you work on Kenji?

 

Not at all! Go ahead. If they need more I have a couple others I didn't post and I can easily get more if needed.

So far I have been talking to Sharif, who has been talking to Kenji on my behalf. But I will probably contact him myself come next week. As you said he seems to be the key guy at Greddy USA.

 

dandy-do you have the water temp too?

 

wrong crank pic, I need the pulley one (REF) please.

But why are you using the flywheel crank sensor? I thought you guys were supposed to use the crank pulley sensor instead? IIRC the flywheel signal is only to tell the ECU what rpms the engine is at. The crank pulley (REF) tells the engine where top dead center is and this is the one I advance with the SMT to get more or less timing.

But thanks for the cam sensor pic, but could you also include a pic of the crank (REF) and cam together in phase on a two channel scope? As well as a pic of the crank signal by itself.

 

Maybe that is why the EU is not working, you are using the WRONG Crank Sensor.

The VQ35 only has one crank sensor while we have two. We need to use the Crank REF.

 

Dandymax,

Go outside and change that wire, and come and report back

-matt

 

Joe I can get you what you're asking for yes, shouldn't be a problem.

But the reason I used the POS (flywheel sensor) is because after talking with Sharif that's what I was told to do. I asked him if I should be using the REF and he said the VQ35 was unique but for older cars the POS was used to pick up rpms and the CAM was used to pick up timing.

The thought did cross my mind that perhaps it was the wrong crank sensor but then I got so focused on checking the signals I forgot to try the REF... I will switch them up and see what happens.

 

Look at N-10
G = Cam Angle Signal
Ne = Crank Angle Signal

They have it wired differently. Only on 99's it is like this
Pin 44(G) is the Cam Phase
Pin 46(Ne) is the Crank REF

On 95-98
Pin 44 is the Crank REF
Pin 46 is the Cam Phase


Just make sure you wire it right, Greddy wants you to tap the Crank REF.

 

Well I just got back in from outside... tested it using the REF, it still doesn't work.

I will discuss all of this with Greddy beginning of next week.

 

Which Firmware was this with? And which engine?

 

Tried versions 1.01 and 1.06, all VQ's, VG, RB, even the SR and CA for fun.

 

Oh damn,


Time to get a scope of the CRANK REF

 

Yep, that's coming tonight hopefully. It needs to stop raining though.

 

Didn't get a chance to get more signals scoped last night - did it this afternoon instead.

Here we go:

 

Ah ha, I guess I can understand where those spikes are comming from. See how in just about every series there is one extra high voltage peak? I think that is why the SMT fcks up reading it.

 

BTW, thanks for getting the signals

Now Greddy has no excuse for not being able to fix it. They will have the signals and just have to add it to the firmware.

 

No problemo..


My sentiments exactly.

 

Where in the Greddy software is the revlimit thing? I only see it for the Ignition revlimit.

 

It's a separate map, go to the map select tab and choose Rev Limiter Cut Setting. Then you'll be able to display it on the tree at the left.

 

Have you tried the revlimit increase w/o the ignition?

 

Not yet. In lieu of using the crank I will try the rev limiter using the ignition signals to pick up rpms. I also need to get my wideband hooked up too. I've been concentrating on trying to get the crank/cam signals to work so that I could see/advance timing.

 

Dandy what's your email address? I'm going to CC you the messages to Greddy from now on.

 

Alex, you still want the harness?


Thanks to you Dandy, we might get teh SMT7/6 working perfectly.

 

Yeah, I'll get back to you this week.

 

Ya, that'd be good. Thanks Alex. Email is dvrditar @ hotmail . com (w/o the spaces).

 

I got mine running last night off the ignition and tach signals, however I'm getting a pending and CEL code P1320. I'm hoping the POS vs. REF is why?

 

What????

Which crank sensor are you using?

 

Well that'd be awesome for you guys if you can. It can't increase the rev limit though right?

 

Pos...........

 

No, it cant



Alex:0201(P1320)
Diagnostic Trouble Code 0201 indicates a problem with the ignition coil and power transistor. The ignition signal from the Engine Control Module is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit.

The malfunction is detected when the ignition signal in the primary circuit is not entered during engine cranking or running.

The items to check include
- Harness or connectors (the ignition primary circuit is open or shorted.)
- Power transistor unit built into ignition coil
- Condenser
- Crankshaft Position Sensor (REF)
- Crankshaft Position Sensor (REF) circuit

I dont understand how you can get the code if you only TAP the sensor. Your sure it its wired properly?
