whoever your tuner is should not be tuning! OEM IAT sensor on a Skyline is a big no no.

Yes

Sounds like you've described R33s too lol

just broscience brain here, somehow the speedo mechanism itself has been come overly magnetised from some huge inductor near by? maybe it's 5G interference LOLOLOLOLOL... (this is a joke for anyone that thinks I am being serious).

I suppose this is adding value to this thread too Note the scaling on the RPM axis too, you pretty much want to close up the throttle so the revs drop a bit quicker and once it kisses the cell with higher timing it will hop into the lower load cells and the RPM will drop again. Also one thing to note, you want to not overly make the idle control closed loop too aggressive as it will end up hunting. This seems to work for me, however I did notice after a hot session on the GP Circuit the car was hunting a bit (I suspect I needed to close up the throttle a bit more). Sure this is completely stupid, but so is a T51 SPL compressor mod. Some would argue modding an old car is stupid too (I agree here) and to just buy a F80 M3. We mod these Skylines because we are not normal.

You need to punch a timing hole into the zero demand table so the motor becomes inefficient at the idle RPM. I'll post up screen shots in a bit 😎

Add into that list RB30ET, E15ET, etc.

A push rod V8 with 2 valves per cylinder sounds broken to me. All subjective 😊

Lol .. I'm not on that T51 mod band wagon. No silly mods on my compressor cover except for a welded on cast elbow on the outlet.

So all the factory trucks and buses that have wild single note dose are running bad? Not sure running bad and dose are related in anyway tbh.

Dose and anti lag another day, I can hear the 007 Die Another Day sound track in my head now lol.

Maybe in a F1 car, but not our shit boxes to be honest. Like GTSyoda explains, it's fark all.

But dose is betterererererer 😂 Sacrifice longevity with ear sex.

This part I find a bit some what controversial... I run one, have always run them to stop things melting at the track. All my turbos have been fine, just the motors explode instead 😂

This, also don't disconnect the stupid OEM MAP sensor, even if you've disabled it in Nistune it does some strange shit once you start to feed in decent boost as it keeps smashing the very last load column. I hate tuning R34s using Nistunes, massive pain in the arse. Sell the Zeixtronix Flex kit, just buy a flex sensor and invest the difference in a Haltech or a Link or similar.

You are correct sir! Been a while since I've tuned an Adaptronic! And I hope it's not bits of motor that smashed into your turbo, we know how that ended for me....

Whoaaaa god level lol.. Sensational bang bangs

Lol it is, just too much retard in Bill's case. Never go full retard, only half retard. (Single digit ignition retard numbers for next turbo lol).

Stop start.... "saves fuel, good for environment", nothing about oil consumption because motor is never at temp, car battery consumption from constant stop/start events...

into the bin, (not sure for R34s but in S15 it's actually a pressure relief valve and as soon as you add boost it cracks open and your fuel pressure turns to shit).

Nice Radium fuel filter too @Murray_Calavera 😎

Need your tune file, the logs you posted before were pretty terrible lol. There should be another table for RPM vs MAP too. The RPM X TPS only shows part of the picture. Highly suspect your fuel pump is garbage.

Got to be super happy with that low down, nice and early. What dreams are made of, if you have VCT or similar.

ex Nankang AR-1 owner/user too - they're grippy tyres, until they just give up without notice and you slide off the track lol. I tried to use the same set a few years later (after the motor exploded, covid, etc.) at Luddenham and they were terrible, understeered all over the shop and kept allowing the rear end to bake tyres.

Yep that's fuel pulsation, try pull off your return line (post reg) and dump it into a jerry can. Does it go away?
