Also would be interested in your voltage values for the fuel level

I still haven't gotten around to sorting this yet, but I will soon. 

I didn't think I'd have any speed bumps other then the charge light =/ When I get around to doing this job, I'll pull the dash out, take the car for a drive and see what else breaks. 

I'll post up the fuel level vs voltage table that I'll build as well when its done.

So this is what I’ve worked out that you need to sort if you replace the dash;

battery light

central locking control unit

interior light (I think the door light on the dash powers the interior light when you open and close the doors.

speed sensor 

 

then the wires you need to add to connect to the new dash are the indicators, hand brake, high beam

I used the fuel sender value I found on HERE

I really didnt want to pull the sender out at the time. I'm curious to see your readings

 

On a side note you may need the Haltech GPS module to clock the speed correct for the IC-7. The speedo signal goes to the OEM cluster before the ECU which makes it a pain to get the speed correct.

I have my IC-7 installed and I can confirm the interior lighting works w/o original dash

The IC-7 can display the battery voltage/set alarms so there's no need to wire for the light

And annoyingly, the IQ3 dash GPS is not available on the Haltech CAN, so you end up needing 2 GPS receivers :/

I have an R34, may be different?

And i think the battery light is wired in as an exciter for the alternator? Without it the alternator may not be charging your battery properly?

On my car we took the speed sensor wires from the Gearbox and then and spliced them into the wires going to the ecu, so we bypassed the dash. 

Sorry just to confirm i used a GPS speed app on my phone to work out what 60kph is.

Then in the haltech ecu I went to the speed sensor page and hit the calibrate button when i was doing a constant 60kph according to the gps app.

Once that was done it was all calibrated and perfect :)

Just needed to calibrate it, which was pretty easy, got my phone out, did a constant 60kph on a straight road, hit the calibrate button, and now its perfect

Copy. So just the signal to the proper pin (53 on R33) at the ECU then ground (any ground)? Does the R34 VSS go to the dash first like the R33?

 

I may try this and see what happens. I really didn't want to GPS module for the possibility of it dropping out.

R34 GTT went to to the dash first. There are two sensor wires that leave the gearbox near the front cross member on the driver side. I cut those, then wired in some new wires, went up through the gearbox shifter and routed them to the ECU. There are two wires, they are non polarised so it doesnt matter which way they are wired. There is no ground.

Also sorry my interior light still works, but doesnt automatically turn on when u open the door. i think it ran off the door open light on the dash

Ok. I will try to mess with this over the weekend. I will still install the GPS just in case I have troubles.

So re-wire directly to the ECU, one wire to VSS pin 53 and one to 12v power on the ECU

there should be two pins for the speed sensor on the ECU.....

OK for the R33, 7 is the Tacho speed signal and 53 is the vehicle speed sensor. is the tac signal the 2nd pin? that the only other pin  i assume get spliced

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
