Not to happy With my time as i couldnt launch her properly, I ran consistent 13.7's with 2.5 60ft @ 109mph.

Was Missfiring a little bit to and that was running 0.8 bar boost, This week im going back and going to sort out this missfire and try and run 1 bar or so.

My mods Include:

Apexi Safc 2 and SITC

Z32 AFM

Mv Shift Kit

3inch turbo back exhaust

Greddy Profec A boost controller

Sard fuel regulator

GCG Hi flow Turbo

Hks Front Mount Intercooler

Bosch 040 Fuel Pump

Plus More but can think of anything now

Tuned for 1 bar Boost (230rwkw)

So it was probably running a little less power than what it could have, but just really dissapointed with my 60ft times, Tried overdrive off with manual shifting and in Drive Stalling it Up With Handbrake i had 5 runs all within one hundrenth of a second of each other.

Im Running Standard Suspension that needs replacing, and running 18inch wheels with Pirelli P Zero Rosso Tyres, Can anyone sugest how i can get my 60 ft down to 2.1 I know the car has more in it if i can just sort out my crap takeoff? Should i replace my shocks with stock ones as i would think soft is better for the drags or should i buy Some Coilovers? Or Stall Converter? Thanks in advance any help would be appreciated.

Can anyone diagnose maybe where i went wrong her's my time slip and old dyno Graph can't find latest one.

Was there any wheelspin involved. I deflate my tyres to 18 lb and cook the shit out of them in the burnout. I am running manual with at least 40 rwkw's less than you and run 13.5's. Autos i have no experience with in a drag situ but i guess all you can do is load it against the torque converter as hard as it will hold and letterip.

Exactly as Fineline said, is there any wheelspin involved?? Sounds like there isnt. You need more bottom end grunt to get out of the hole. Suspension won't do nothing if your not spinning the wheelspin. Maybe a little more boost is needed and probably your best bet would be a stall convertor.

yeah i did a burnout to warm up the tyres, I stalled it to about 2800rpm just before wheel spin then step on it. It just doesnt hook up quick enough when i let go of the brake, its almost like it hesitates then she starts to move.

Otherwise if i stall any higher it results in heaps of wheelspin.

Probably going to fix the missfire tomorrow and try and get some stockies for the back, and get some semi slicks or something and see if that helps, and run a bit more boost.

My 60 ft's killing my time probably doesnt help that my shocks are stuffed either.

thanks for that robo i was considering getting a stall converter might look in to it now, yeah will probably try again this week with more boost and stockies with semi's and see how that goes. Otherwise i will be getting a stally next week :-)

My auto r33 has the same issue..

235rwkw and hesitates off the line..it is due to the power curve in it though and that my gearbox is shitting itself..i only had a safc with no ignition tuning done..

have you got a dyno print out?

I think you need a bigger stally with the tune by the sounds of it..or more midrange in it..

Try stalling it up so it spins a little then take off and feather the throttle a little..if you get the wheels spinning a tiny bit i think it will launch off once it grips, a little wheel spin off the line is good ive heard...

stally is the way to go i think thought it could have launched alright without it but it doesn't seem to be so, what time did you run with 235rwkw? really happy with the speed of the shifts though its just getting it off the line.

Havnt run it yet was going to on anzac but it was cancelled...

The auto is dying in it now, as it was not in good health before the increased power either, so I may not run it until i get a stronger box or put a manual it in..unsure wat to do at this stage..

With that mph your car is more then capable of running hi 12's. Like you said if you get it sorted it will be one quick machine..

A stally would be the go..You would also get a better and earlier curve with a replacement ecu but youve got a ecu controlled auto is the only issue..

Good luck

yeah was aiming at hi to mid twelves when i first started this project, this was the only route i could have gone with the auto is using an SAFC and SITC Combo i have been looking at the new apexi piggyback but don't want to be the first to try it, incase it doesn't work to well.

Edited by wildr33gtst

though the most important thing when it comes to ecu selection is its not what ecu suits you or your car. Its the ecu that your tuner is comfortable with and specialises in...I think the tuner is way more important then any ecu selection..

When I got the SAFC tuned though the tuner said with out ignition control he would not get a good midrange out of the car...

i agree my mechanic which is racingline likes the power fc, but i have been researching this for a few years now, and i have always been worried about the auto not shifting properly because of the gear logic in the ecu, most aftermarket engine managements are not made to support autos, otherwise i would have went that route, some people say the power fc is alright on an auto and others say it wont shift properly because it doesnt cut the ignition timing on gear changes, so i opted for the only proven ecu combo which was the SITC and SAFC2, waiting to hear feedback from the new apexi piggyback that has been released which retains the standard ecu and has better tuning points for ignition and fuel than my previous setup i have now.

I have also been looking into the greddy ultimate because apparently it runs auto but i havent seen many people try it yet, I still flipping up what to do.

Edited by wildr33gtst

any piggy back wont affect the auto as its pluging into the standard ecu, even though the auto is onctrolled by a seperate auto only ecu it is linked..

The bigger the risk the greater chance for reward. Also higher risk of loss though. You auto may blow up..get another one for a couple of hundred bux..haha.

Cheers

here is my old dyno sheet cant find the latest but i'm going back on wednesday to take a bit of fuel out up top, because its hitting the fuel cut, probably because i got it tuned on a 35 degree day earlier on in summer. When i ran it it was on 0.8 bar boost because of the fuel cut, so hopefull pull 240rwkw or so on wednesday. Can anyone tell me if this is an alright dyno graph will post new one up on wednesday.

    • I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.
    • Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too. 
    • Any update on this one? did you manage to get it fixed?    i'm having the same issue with my r34 and i believe its to do with the smart entry (keyless) control module but cant be sure without forking out to get a replacement  
    • So this being my first contribution to the SAU forums, I'd like to present and show how I had to solve probably one of the most annoying fixes on any car I've owned: replacing a speedometer (or "speedo") sensor on my newly acquired Series 1 Stagea 260RS Autech Version. I'm simply documenting how I went about to fix this issue, and as I understand it is relatively rare to happen to this generation of cars, it is a gigantic PITA so I hope this helps serve as reference to anyone else who may encounter this issue. NOTE: Although I say this is meant for the 260RS, because the gearbox/drivetrain is shared with the R33 GTR with the 5-speed manual, the application should be exactly the same. Background So after driving my new-to-me Stagea for about 1500km, one night while driving home the speedometer and odometer suddenly stopped working. No clunking noise, no indication something was broken, the speedometer would just stop reading anything and the odometer stopped going up. This is a huge worry for me, because my car is relatively low mileage (only 45k km when purchased) so although I plan to own the car for a long time, a mismatched odometer reading would be hugely detrimental to resale should the day come to sell the car. Thankfully this only occurred a mile or two from home so it wasn't extremely significant. Also, the OCD part of me would be extremely irked if the numbers that showed on my dash doesn't match the actual ageing of the car. Diagnosing I had been in communication with the well renown GTR shop in the USA, U.P.garage up near University Point in Washington state. After some back and forth they said it could be one of two things: 1) The speedometer sensor that goes into the transfer case is broken 2) The actual cluster has a component that went kaput. They said this is common in older Nissan gauge clusters and that would indicate a rebuild is necessary. As I tried to figure out if it was problem #1, I resolved problem #2 by sending my cluster over to Relentless Motorsports in Dallas, TX, whom is local to me and does cluster and ECU rebuilds. He is a one man operation who meticulously replaces every chip, resistor, capacitor, and electronic component on the PCB's on a wide variety of classic and modern cars. His specialty is Lexus and Toyota, but he came highly recommended by Erik of U.P.garage since he does the rebuilds for them on GTR clusters.  For those that don't know, on R32 and R33 GTR gearboxes, the speedometer sensor is mounted in the transfer case and is purely an analog mini "generator" (opposite of an alternator essentially). Based on the speed the sensor spins it generates an AC sine wave voltage up to 5V, and sends that via two wires up to the cluster which then interprets it via the speedometer dial. The signal does NOT go to the ECU first, the wiring goes to the cluster first then the ECU after (or so I'm told).  Problems/Roadblocks I first removed the part from the car on the underside of the transfer case (drain your transfer case fluid/ATF first, guess who found out that the hard way?), and noted the transfer case fluid was EXTREMELY black, most likely never changed on my car. When attempting to turn the gears it felt extremely gritty, as if something was binding the shaft from rotating properly. I got absolutely no voltage reading out of the sensor no matter how fast I turned the shaft. After having to reflow the solder on my AFM sensors based on another SAU guide here, I attempted to disassemble the silicone seal on the back of the sensor to see what happened inside the sensor; turns out, it basically disintegrated itself. Wonderful. Not only had the electrical components destroyed themselves, the magnetic portion on what I thought was on the shaft also chipped and was broken. Solution So solution: find a spare part right? Wrong. Nissan has long discontinued the proper sensor part number 32702-21U19, and it is no longer obtainable either through Nissan NSA or Nissan Japan. I was SOL without proper speed or mileage readings unless I figured out a way to replace this sensor. After tons of Googling and searching on SAU, I found that there IS however a sensor that looks almost exactly like the R33/260RS one: a sensor meant for the R33/R34 GTT and GTS-T with the 5 speed manual. The part number was 25010-21U00, and the body, plug, and shaft all looked exactly the same. The gear was different at the end, but knowing the sensor's gear is held on with a circlip, I figured I could just order the part and swap the gears. Cue me ordering a new part from JustJap down in Kirrawee, NSW, then waiting almost 3 weeks for shipping and customs clearing. The part finally arrives and what did I find? The freaking shaft lengths don't match. $&%* I discussed with Erik how to proceed, and figuring that I basically destroyed the sensor trying to get the shaft out of the damaged sensor from my car. we deemed it too dangerous to try and attempt to swap shafts to the correct length. I had to find a local CNC machinist to help me cut and notch down the shaft. After tons of frantic calling on a Friday afternoon, I managed to get hold of someone and he said he'd be able to do it over half a week. I sent him photos and had him take measurements to match not only the correct length and notch fitment, but also a groove to machine out to hold the retentive circlip. And the end result? *chef's kiss* Perfect. Since I didn't have pliers with me when I picked up the items, I tested the old gear and circlip on. Perfect fit. After that it was simply swapping out the plug bracket to the new sensor, mount it on the transfer case, refill with ATF/Nissan Matic Fluid D, then test out function. Thankfully with the rebuilt cluster and the new sensor, both the speedometer and odometer and now working properly!   And there you have it. About 5-6 weeks of headaches wrapped up in a 15 minute photo essay. As I was told it is rare for sensors of this generation to die so dramatically, but you never know what could go wrong with a 25+ year old car. I HOPE that no one else has to go through this problem like I did, so with my take on a solution I hope it helps others who may encounter this issue in the future. For the TL;DR: 1) Sensor breaks. 2) Find a replacement GTT/GTS-T sensor. 3) Find a CNC machinist to have you cut it down to proper specs. 4) Reinstall then pray to the JDM gods.   Hope this guide/story helps anyone else encountering this problem!
