Dyno tune will be a while still when I'm ready to adjust the cam gears.Until then its road tuned

N1GTR.. Technically the only thing new about this is the actuators, and I'm sure if you purchaced -9 from gcg etc. they would put on the same 8.8psi actuator like what I got. Otherwise, same -1 / -9 / Gtss unit.

I think response can be tweaked further with the tune and also with boost control as there is no creep and very minimal spike(1psi) as is right now, so definately some gain to be have there, even if minimal.....and then there are cam gears

Have only been driving it a few days, but it does pull a touch harder on 13psi, But so far I'm satisfied that I have turbs capable of 300rwkw with stock like response.

Aaaaaah my bad!

Here's what I thought you meant;

This is the last dyno tune I had, -9's, nismo pump, 555cc injectors, nismo AFM's, cam gears, stock engine.

Figures in all wheel killerwasps.

Since then I have fitted a different boost controller and the wastgates are now set to open at 16PSI with controller off.

Needs another tune to set boost controller and get rid of the drop in boost pressure. 22PSI tune to follow.

I'll let you guys know....

Aaaaaah my bad!

:thumbsup:

I guess they didn't say anything about injector duty.

I was seeing roughly 90% on a cold night with 22psi peak in the midrange through to 17psi or so at the top end. Rich enough to see black out the back on full boost :whistling:

Stock fuel reg too....

Should be okay, guess I'll find out.

Well since there is NO info on this here I just thought i'd put this up and update as I go along.

The comparision below is results for the -1 turbo which is the -9 that comes with a 8.8psi actuator from Garrett, compared to stock R33 Gtr turbos.

The top window is the -1/-9 which reaches the same level of boost(13.3psi) about 200-300rpm later than the stocks, and the car drives basically the same as before.

The ONLY thing changed was the boost level was raised only one notch on the controller (profecb2) to get the same level for comparision....start/gain etc was left the same and the pfc tune was untouched.

My boost control kit reads 1psi low for some reason, hence 13.3psi

Ignore the scale on the bottom as this would be different due to the length(secs) of each log

Well with two turns in on the actuators I was able to get it down to stock like response, well on paper at least....To me it feels even better than stock coming into boost

Top -1/-9, bottom is stock

Is boost creep the only thing to look for with too much preload? I want to shorten them some more :yes:

    • Hi GTSBoy, Excuse my ignorance but what does a "Bad" Knee point mean ? 
    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
