Hey guys,

I recently made one of the luckiest phone calls of my life and happened upon the opportunity to trial a new tuning program that can manipulate the factory ECU is most Nissans, including all skylines. The guys at BPS at Cleveland in Brissy were able to change the factory air/fuel ratios, as well as factory boost levels with the standard boost solenoid. My car is an R34 with the tiptronic semi-auto and I have been looking for something like this for a while now and I'm totally stoked with the results.

My car is pretty close to standard, the only mods are:

- K & N Pod filter

- Blitz LM FMIC

- BOV

So as you can see I don't really have any substantial power mod upgrades... not even exhaust yet.

On the first few runs the car dynoed between 155 - 165kw at the treads. After some adjustments, and an extra pound or two of boost and it ran 183.5KW ATW!! With room for more potential, AFM was maxed out due to a boost leak in my cooler piping. Dyno sheet won't attach, but ill work on getting it on. I think the results speak for themselves, pretty awesome option for anyone not wanting to fork out the expense for a full after market ECU.

If anyone wants any further info hit up the guys at BPS and they'll be happy to help you out.

Cheers,

Jizm

Good on ya mate. You got some decent results.

Only thing I find weird is that you proceeded to tune the car with a boost leak instead of fixing it?

Now your going to have to get another tune once you fix? If it was so simple as a cooler pipe why didn't the guys at BPS fix it before tuning (or when they found it)?

It will be good to see the Dyno sheets once you can attach them.

I was the test dummy for the program so I actually got it for free... but i think your looking at around the $1000 mark, if ur interested I can give you the phone number and BPS can hook you up with a quote. And yes, that does include timing.

Reason it got run with the leak was because it wasn't detected right away. I was keen to get the car back, and we didn't have time to pull the whole front bar off to adjust the hose clamp. I'm fixing up the leak and taking it back down early next week. Might see if I can get my exhaust fitted before then as well to take advantage of the free tune. ;)

Still working on the dyno sheet.. won't upload as an attachment

Lol, sounds like I need far more technical info, I'll phone up tomorrow and get the full details. I don't think its just a remap because from my understanding (which is clearly limited) they install some kind of emulation software into your ECU... Don't quote me on this but I'll find out for sure tomorrow and clarify any questions. I'm quite sure I haven't been taken for a ride because I was of the opinion you can't change factory boost levels and remove speed limiter and boost cut. But like I say, I'll find out full details and end speculation. Watch this space for more details.

Hey this tune sounds good, Ive currently got a 3inch turboback exhaust system with high flow cat, podfilter & a turbotech boost controller boosted to 10psi. How much Kw's can i get out of this if i tune like what you did? Thanks would appreciate it.

If you are looking for a remap then speak to someone such as Dr Drift as he is in Melbourne.

You would get anywhere around the 180-190rwkw mark with those mods and a remap.

Nistune now has a realtime daughterboard for ER34 and we are gathering an extensive collection of various ROM images to support the variety of different ECU part numbers in our next ROM pack release

(We have noticed earlier types dont have the traction control facilities and there is extra stuff for tiptronic automatics in the later ECU ROM revisions)

We have had several workshops install them in Australia and some individuals running them overseas... We are still field testing S14A/S15 and OBD-II USDM ECUs at the moment with the same board. Once that is done we will start advertising the boards on the site. But ER34s run without any problems

For a sneak peek we have the Type 4 hardware installation manual at www.nistune.com

Basically they make the ECU tunable like an aftermarket ECU like the powerfc

I went down and saw James at BPS today to get some more info for the critics.

This is how it goes, similar to what darkhalf mentioned about the Nistune program (nice hi-jack), the tuner can manipulate the factory ECU in real-time, much like an autronic or Power FC. This is achieved by adding new hardware to the factory ECU (daughter board). This acts as an external storage device which contains maps for the ECU, which is different from a flash tune, or simple remap and is better because it doesn't simply "trick" the ECU into running different settings. From here the tuner can remove the speed cut, adjust boost, timing and fuel. The good lads from BPS will soon be providing a more in depth explanation after everyone has finished having their rant.

The results are quite impressive, in fact with my new exhaust the car dynoed at 198.9kw atw, which I'm stoked with. For some reason it won't let me upload my dyno sheets, anyone got any suggestions?

I'm really happy with the result and I'm sure plenty of others will be to. Keep on eye on this post for some more specifics. If you like what you see James from BPS Cleveland is the man to speak to.

Ta,

Jizm

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
