You are right, the issue is 95% of peoples rims are over track or the offest it wrong, also people put mismatched skinny tyres etc etc on them. Much easier to just keep a set of stockies for regency trips.

I've been told the neo motors also do.

Well it basically has to be one of these things, how else does fuel magically get into the cylinder?

Auto definitely helps with turbo lag and spool.

As I said you need to graph all injector values to see why it is getting more fuel. Opening time, pulse width, fuel pressure, voltage. Fuel pressure I imagine you'll have to have someone sitting there looking at a gauge but it is better than nothing.

Even using multiplexing wouldn't be very expensive or difficult. I'm still fairly baffled why they would do this.

If the consult port still works with a powerFC just use ECU talk and log afm voltage and graph it, very easy to use piece of software.

Or just monitor the signal with a multimeter lol. Better yet an oscilloscope but I doubt you have one of them lying around. Surely the powerFC software can graph AFM volts vs time though? That would be the easiest way to see.

How does one tune it to suit then?

Car came with it and I don't have the stock airbox.

All the cars I mentioned nissan released from the factory with a MAF and no BOV. I realise that the new cars did hence I wanted to know how they tuned it out. This thread isn't about should I get a bov or should I make my car flutter, it is how did nissan tune out the stalling issues, that is all. With a pod my stock BOV was ridiculously loud, I ended up making a small gasket for the BOV so that it couldn't vent as fast, it still stops reversion (doesn't flutter) but it is much quieter now.

mafia just stop posting, ironically you are the one who is being a dickhead here.

Im actually a programmer and one of my job was writing software for old processors, namely the same cpu used in these early boards. The code for writing to 2 outputs vs 6 and doing sequential vs batch is basically identical, the cpu still runs fast enough to process that many events. I can't see the CPU being the limiting factor, would have been something else but f**ked if I know what.

I never understood why they did batch mode injection, FETs are like $3 each for high amp ones.

Pretty sure ignition is because you have 6 ignitors, if it was batch they would save money and use 2 or 3.

I meant more appropriate than a gtx35 if he was set on a gtx turbo.

turbo: gt3076/hypergear highflow/kando injectors clutch tyres fuel pump intercooler ecu suspension a tune by someone who wont blow the motor up Will be close to $10k once you do all of this and fix all the things that break along the way. Personally I'd sell the car and buy one that already has 300rwkw, $10k + the price of an R34 will get you a very tidy nice example! MUCH better value imo, buy someone elses money pit and spend the extra getting it up to your standard.

Personally I don't think there is a huge performance or fuel economy in going to fully sequential from batch mode but if you can I would. Personally I'd stick with the nistune as it looks legal, easy to tune, cheap and plug and play. That and there are more nistune tuners than haltech tuners, I've heard the software is a bit average to use as well though this was earlier models from years ago. Interesting, I had read that it was fully sequential before 4k and then went batch mode but no one ever confirmed either way. I have been told the neo ECUs are fully sequential, do you know if this is the case? If you could link me to the nistune thread I would be very interested to read about it. Thanks.

What power level are you aiming for? A GTX3076 might be more appropriate.

Yep that is all they are checking, however they will give the car a full road worthy at the same time, that means checking bushes, oil leaks, suspension components etc. So your car has to be returned to stock with normal ride height, stock rims etc etc.

Graph all injector values vs time and compare when it is fine and when it isn't, see if stuff like pulsewidth/latency is changing etc. This way you don't need to look for what COULD change these things, you can just look at what IS changing and then work backwards. This is assuming the ECU is powerful enough to graph random variables like pulse width etc which would never normally change. Also get someone to look at the fuel pressure when it is fine and when it isn't making sure it doesn't change. Ultimately it sounds like an ECU issue where one of these variables is getting reset or changing for whatever reason, either that or some weird trim/compensation map is kicking in. Something else worth graphing is the rpm and load (whether it is afm or map) when this happens, see if the RPM signal changes dramatically or the load suddenly doubles even though it hasn't actually. Could be a faulty sensor.

The wastegate flap looks like it is opening the wrong way, the flow will be going downwards, surely if the flap opened from the bottom it would flow better? As currently it will have a huge restriction.

Read all of my posts, you don't need to engineer a 25 swap in SA, you just go through a full defect inspection which was $172 when I did it, $90 for a reinspection if you fail. Applying and getting the documents is free.

http://www.infrastru...n/vsb_ncop.aspx this is the document you want http://www.infrastru...n_2011%20v3.pdf mainly these bits is what you have to comply with "When lowering a vehicle, the ride height of an unladen vehicle must not be changed by more than one third of the working travel of the suspension from its original height to a rigid bump or rebound position specified by the manufacturer. The suspension bump and rebound positions are measured with any deformable bump or rebound stops removed. The original relationship between the front and rear suspension heights must not be changed and therefore the front and rear suspensions must be both raised or both lowered by the same amount" You must also not exceed the minimum clearance which I believe is 100mm from the lowest part of the car. Also if you change suspension geometry in the process this has to be rectified.

A-Z of shit music, triple J absolutely destroy them, f**king hilarious
