ok. i've checked out both the original power graph and the new one. even on the old graph the car still wasn't running lean. i think its amazing that all you armchair mechanics can pass all these comments without even seeing the car or working on it to know what its doin and what power its making in relation to air/fuel and boost pressure. maybe you guys hould think less about how much boost pressure its making and be more concerned about the power output!!!!!

i have to agree with cooldude! how can you no what that particular engine needs from your computer seats?

Attack of the noobs. How many cars have you personally dyno tuned from base tune? FYI when you are tuning a car, you basically dont look at the power output, whatever it makes, it makes. If its down 50kw at the end, its either mechanical or the tune.

what exactly is a 'noob'? or are you just guessing that its a word just like you are guessing about what the tune for this car should be. its pretty easy for all you guys to hang shit on people for doing their job when its possible you wouldn't know one end of spanner from the other

i hope you have more then 700hp at the rear wheels?
.

yeah just a little under 900 at all four wheels and losing traction. how bout yourself? :)

oh and cooldude1000...the spanner you need at the momment is a size suitable for you.....6 millimeter au't to do it...it'll have to do cause i dont have one smaller that you can borrow. .........noob.

I know your a spanner.. does that count?

WHOW!! you should be really proud of yourself you actually no ther is a 6mill spanner nice work, you must be a mechanic i wouldnt hang shit for all you no he might be a dyno tuner!!!

Who cares if he is? I wouldn't take my car too him based on his comments below

Go look at the comments, and by whom they are posted. People with a substantial more than armchair experience.

Some have tuned cars with over 300rwkw from scratch, some full engine builds, some full engine conversions and so on.

If you try and say that first graph, the car isn't running lean with a AFR of 14.25:1, then you sir are an nothing more than a fool

Posts in this thread are about the poor AFR ratio and the average midrange that is associated with it, that is directly correlated to boost control issues or something else as it has a fairly wonky dip in there that should not be there.

lol

dear dick face look up what the stockometric air fuel ratio is for a stock engine is!! you must be the f**k wit that owns a black car that dosent show up particulate matter(hydrocarbons) which is unburnt fuel!!! all over you bumper bar.

its obvious that you want to be running a richer than stoich when your producing bulk power but the numbers these guys are talking about are ridiculous. these guys still need to find out what the stoich afr is and then go and re-check your figures and then maybe you can pull your dicks out of each others asses finally

This thread has become immensely entertaining :)

These are my fav bits... completely nonsensical...

Really, the best bit, is one guy with 3 posts, agreeing with another 3 poster... both of which joined 1 day apart... *cough* IP check

i have to agree with cooldude!

cooldude/paintman... Why do you feel the need to make personal attacks?

Peak torque is made as the afr's spike to 14:1. Not good.

Simple as that.

So pull your head in and discuss not attack.

    • Yeah, hard to find and a pain in the ass to change with the transverse engine. I’ve worked on a GTiR before and it’s not a job I’d ever want to do again. theres a company in South Africa that makes RS3 gearbox adaptors for the AWD SR20 including gearbox mounts, so I could modernise it and go a dual clutch with paddles. For now tho, it ticks all the boxes. Super cheap, can throw the kids and their junk in the back, and SR20 that I can turbo cheaply, a CVT that’s not a dog’s breakfast like the V35, and has 80% interchangeable parts with stuff I can source from the wreckers cheaply…. But it’s still unique. I love the wagon back of the Autech version. It’s cheap enough that I can buy another stock manual FWD Primera with SR20VE, swap the gearbox to the N15 pulsar short gear ratio box, swap out the brakes to the R32 ones I pulled off my 32, register it on club plates and take it racing. $1300 shipping from NZ. Heaps of parts and aftermarket builders for transverse SR20’s in NZ.
    • Hard to say, just pop the rocker covers off and have a look if you think it's cammed. You probably need to replace the valve cover gasket/half moons anyways.
    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.
