This jogged my memory to post up these pics of the VQ25det plug, DD plug and whatever plug the last mech installed into the 25DD I have here.

Blanking off my egr dropped fuel consumption from 12.5l/100km to 10.6l/100km city driving. And no more soot.

probably needs an idle air volume re-learn.. assuming the VQ30 has this opiton like the VQ35 does.

My car is not a vQ25 that ain't even my engine type

I think you'll find it's a VQ25DD (the direct injected variant of the VQ25). Still doesn't make it OBD2 compliant. Based on what my local Nissan dealer told me you can use Consult 2 to gain most information (that's what they used on my VQ25DD) and Consult 3 is better.

Have anyone ever experience a p0100 on a Nissan skyline v35 250gt what is that

Are you back on the "cheap stuff" again? Scotty nm35, a well respected member here answered your same question back up there on posting #204. It refers to a faulty AFM.

If you have no idea about fault codes, or google searching fault codes, or repairing faults, there are places you can take your car where they know how to fix it, where there are men willing to get their hands dirty to save you doing the hard work... ;)

With no location listed I can't help you find one of these specialists spector. Sorry.

Hi everyone,

I have a 2003 V35 GT300 and I would like to find more info on the EGR block off mod. I tried to search the forum but came up empty...

Also I did the throttle plate clean and I got the check eng. light on performed a ECU reset and the light went off but... when I start up the engine it revs somewhat high to about 1500 RPM for a second or two and then settles would that be normal? I have not noticed that before the clean.

Any help would be greatly appreciated.

Thanks

How do I do that as I don't have the "check engine" light on?

Idle Air Volume Learning (Throttle Position Learning)

It is better to count the time accurately with a clock. 1. Perform “Accelerator Pedal Released Position Learning”.

2. Perform “Throttle Valve Closed Position Learning”.

3. Start engine and warm it up to normal operating temperature.

4. Turn ignition switch “OFF” and wait at least 10 seconds.

5. Confirm that the accelerator pedal is fully released, then turn ignition switch “ON” and wait 3 seconds.

6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.

7a. Fully depress the accelerator pedal (HARD)

7b. Fully release the accelerator pedal.

8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.

9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.

10. Start engine and let it idle.

11. Wait 20 seconds.

12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.

Realistically the idle relearn needs to be done using the consult3, the manual method is hit and miss. It also won't work if you have an engine code up in most cases.

Try it out, if it works you will hear the engine rev to over 2k, then slowly drop to 650 revs. There are other procedures that need to be done before the relearn though, they need to be done in order preferably.

True.. it can be difficult to do with the manual mode. I managed to do it on my VQ35 with a non-functioning CEL.. which added to the challenge.. took me about 20 tries to get it.

You need to do the throttle pedal position learn and the throttle closed position learn first, but they are fairly simple in comparison. It will also only work with an engine temperature within a certain range too.

In the VQ35, rpm peaked up to about 1,200rpm, then dipped to about 450rpm, and settled out at 650.

I was also forced to do the re-learn after high idle problems, post throttle body clean.

Go for a consult3, I know they work fine. Consult 3+ is easier to use but out of my price range.

Never seen one for under $200 work on v35s

Agreed. if the 250 and 300 aren't OBDII compatable, this isn't likely to work. You will need a real consult2 device or a good clone.

You would have more luck with the VQ35 ECU though.. I have the Blatz cable with nissandatascan, and it lets me do this procedure.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
