Quick few questions

Tracing an AN2 Voltage error on the IAT Sensor, the sensor is reading negative temperatures for fractions of a second and then returning to normal, this appears to be linked to my break down issue.

Will trace the cabling and check the sensor voltage as well, any tips on what to set the multimetre at for this? Also just wondering my car also appears to be running a bit hot as well, getting up to 95c on the standard radiator, and this isn't flogging the car either. Running thermo fans, just wondering is it possible my IAT issue is effecting when the thermo fans cut in (controlled by ecu)

thanks (this is on the v44 plugin board ecu)

I would like to hear an update on this IAT vs problematic coolant temp, that coolant temp is very high,

Its great they have finally made every in and out configurable to suit what WE want.... unlike the old days with the G1's etc where , this output is thermofan ...... and thermofan only (or whatever if your happy with the triggering conditions they dictated)

I look forward to the day you can have an option for advanced tuners to be able to enter boolean tables etc , so ANYTHING is possible.... not just what they dream up.....

ie you need 5 conditions met to turn on an aux out.... but they only give you 3 ...

Another words, whatever weird combo you can dream up, you can do simply (!!) by writing the formula...... not selecting drop down boxes which locks you into what they offer only.

Yes i know its probably rare for 90% of tuners... but im sure some of you guys have had situations where you could have done something cool if only the options were there to utilise the in/outs you had spare.

Oh and while im typing.. got a problem i wonder if any of you guys have sorted out.... if not i'll ask LINK to change in an update

Ok, say you want to keep using the MAP sensor in the engine bay connected to the old MAF plug.

Now this comes in on AN4 .... The problem i have is this

If i want to use the ext map, i have two options.... i can call the int map GP Pressure and call AN4 MAP , and link 2.5Bar

That way the fuel table sees the AN4 MAP.... If there both named MAP, it picks the first one, ie internal one.

The problem i have is i think they need to have MAP(MAIN) and MAP(GENERAL PURPOSE) in the select list.... Be abit easier.

The drama is that if you select GP Pressure, that you can only select a CAL table, not just select from the map sensor type list as well....(ie link 2.5 bar)

Am i missing something ?

this thread makes me wanna look into the Vi-pec more... as i have one in my R33 GTS-T but to be honest i have no clue exactly what it has changed... well except gets rid of you AFM stock restictors and makes the car run better... lol

if you want to use an external map sensor instead of the internal one just set the internal one to "off" in the software

no the pnp's run the ATTESSA just fine...its the V88 with the TF electronics adaptor that sometimes has an issue (mine and bigmikespec's)

Thats right, but apparantly it has been corrected. I got my V88 and adaptor board very soon after the product release hence a few bugs still in there, Paul the same (hope you're feeling better too, scary!)

Thinking of controlling the 4WD torque split with the V88, I have not run it by my tuner but it could not be that difficult, just a PWM signal straight from the V88 to the ATTESA pump.

Yes i know that Titan, but i want to still use the second map sensor as a general pressure sensor, but it only gives you the choice of a cal table, and it would be good to still be able to select "link 2.5bar" etc

Sorry, it was misleading of me to say MAP(main) and MAP(GP) .... obviously there is only one map..... just be nice to have the same selection list of sensor types as well as a cal table.

For those who have actually tuned a rb25det with the V44 or G4 plugin, when you set up your timing , assuming your CAS bolts are halfway in the slots...

what trigger offset did you end up with ???

Out of the box, it had -82 on mine.

Initially my CAS was rotated far as it could go counter clockwise, and i ended up with around -113 to get the 10deg to match the crank.

I rotated the CAS to halfway in the slots, (was told that is where most are located stock), and ended up with around -96 to achieve correct timing.

I assume this will give me abit of an idea if my cam timing is out a tooth or not compared to others..... (im chasing probs)

Also, new problem.... just went out to car and tried to pull the logs... says it cant connect..... firmware update cant connect either..... PCLINK connects fine though.....

Removed all usb drivers and reinstalled etc and pclink..... same problem. (I did log in and pull on log off today on dyno using mates laptop, so could just be something with mine... just thought id ask incase someone else has similar and worked it out.

hey mate

my trigger offset is -95deg and my ECCS wideslot is 23deg.

So whatever number you get for the trigger offset is fine mate, -85 is not a issue.

:)

I just loaded the map and re-checked and mine is -95 also Guilt...... so thats a good confirmation.

I assume your CAS is central in the slots ?

Ok, here is reason i was worried...... on 20psi , i was up to 27 deg timing !

On the GTST link, it was more like 15 deg ..... So it took me abit to realise and try raising timing in the maps to obtain previous numbers.

So that had me scratching my head and rechecking ALOT.

And since the CAS was intially rotated CCW fully, timing out of the box was about 45 when ref was 10 !! No wonder it was so responsive on throttle blip......

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
