Yep is is tuned for the mods you list. and you then go by your self to the dyno to get it checked, He guaranteed me if i didn't get a power increase he would write another tune for me after seeing the dyno sheet.

You can get upto 3 seperate tunes sent to you, dyno all 3 and keep the one that suits your car best and send the other 2 back but it costs a bit extra. He was confident he would get it right first time and he did.

Get it right? Or close enough?

Im not trying to sound negative.

But i cant see how someone in another state can tune your car based on what youve "told" them.

Its just pot luck, and it will never be the best tune either.

For $300 it wouldnt wanna be anymore as the tune will never be as good as paying for someone to do it real-time.

Considering you still have to go to a dyno to check, i dunno... im not convinced

What nismod says has some merit to it though.

He is right if the tuner is with you at the dyno you WILL get a better result.

But I did not want to pay big $$$ for a tune as mine is just a mild upgrade.

mabye i could have got a couple more rwkw out of it but I am happy with the results

And like nismod says, he can only go on what you tell him.

Keep in mind there are litrally 1000s of tuners doing it in japan this way, Including some big names.

and yeah it was $150 + $10 delivery + $30 to get the socket soldered in at a tv shop and $80 for the dyno run so all up $270

so the tune was really only half the cost.

I think nissan tune thier cars ritch from the factory, so theoretically its just a matter of adjusting the 'k' value to get the 12:1 afr, im a noob at tuning, so I have been doing a bit of reaserch with the goal of tuning my car, but I would guess this is all he is doing, then you can fine tune from there, I dunno, I have more reaserch to do, and to buy the equipment :unsure:

And what lean out your engine everywhere - thats dumb, thats why noobs shouldn't tune. To tell you the truth I have no idea how this guys sends his programs out every nissan we see at work either needs a fuel pump or the airflow meters are distrorting the real airflow value or the base timing is out 5 or 10 degrees or there is some dumbass idea typical of cheap nissan owners. The chances of getting the mixtures wrong is so much higher with boosted engines.

S/H Ninja - you said your AFM was maxing out before?

The stock AFM should max out at around 200-205 so it would have been well worth your while upgrading to a z32 and getting the appropriate chip to suit. Try winding 4th right out to redline and see if it actually gets there without cutting ignition. When the AFM voltage reaches 5.1V for 3 secs or more your ECU should automatically cut power.

Plus the most you'll ever see out of a set of RB20 stock injectors is 205-208 rwkw so those injectors of yours would be running at 100% or more which is dangerous if the fuel system decides to hiccup for a split second.

I was thinking the same thing, the afm hit max airflow before but now with more power, hence more airflow it doesnt cut?

Was the before dyno run done on the same dyno as the after?

Lastly, I see the run was done in "shoot 3" where usually it would be shoot 6F. Would that affect the power figure? Or is it just a ramp rate thing?

just been reading this topic and my question may apply somewhat

i've got a stock rb20det motor just turbo back exhaust on 10psi atm

i've also got a r33 s2 turbo which im going to be purchasing shortly and i have a fmic/kit which i'm going to be put on the same time as the turbo

with turbo back exhaust, pod, fmic, r33 s2 turbo, is it safe to run 1bar (14psi) without receiving any boost/fuel cuts.. would i need a remap or chip of my stock ecu?

Also why would you scrub out the Ambiant temps and inlet temps unless you have something to hide?

Me thinks you are only making 180rwkw and your tuner put the sensor on your exhaust.

LOL yeah I really need to do that. I dont give a F*#k what sort of power it makes. altho the dyno guy didn't even put the afr's on the printout so i wouldnt put it past him.

Car feels heaps faster and runs perfectly and I have had it tested with a wideband sensor and it is fine.

s*^t some of you guys are negative.

I was just happy with my results and thought I would share. Perhaps next time I will think twice before sharing my mods with others.

dude, you cant blame them for being negative.

these days you truely get what you pay for, and when something real cheap come along, people always think its a scam unless they see some hard proof. and the proof in this case has been tampered with.

I for one wouldnt trust someone over the web to tune my car. every engine is differant, 2 engines with the exact same mods will never make the same power.

just becarefull, cause the money you saved on a proper tune might have to go towards a new engine......

Steve

He knew what he was doing, and the risk. 200rwkw and a nice smooth curve on an RB20 is the result. Time will tell, but it looks like everything went his way this time. I wouldnt get it done, but congrats on the good result mate, thats a happy RB20.

Hey guys - slightly off topic but does anyone know where in Melbourne is good to get a re-map? I know of a couple of places that do it but I am really after someone reputable - I've heard of a 'few' stories of blown RB20s after having had a remap...which is what I am trying to avoid...!! Its not a matter of cost, I personally would rather retain a complete factory ECU rather than a PFC (if possible)...my car is an R32 GTS-t and mods are;

FMIC

HKS 2535

R32 GTR injectors

Q45 AFM

Walbro pump

Any suggestions would be much appreciated...!!!

Cheers,

Chris

    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
    • You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else
    • If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.
    • Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)
