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......

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

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
