Hi All,

I am new to this forum and would greatly appreciate any help.

The Story...

About 3 weeks ago I bought an R34 GTT 2 door... finally... car seemed in good nick, I have done bout 1500km's since and is my daily driver.

Mods:

POD filter

cat back exhaust.

(As purchased)

Now the issue I started having was the engine light, TCS, and slip lights intermittently coming on, they would come on and go away on restart. Sometimes I wouldn't see them for days. After a search around the forums I put it down to coil packs as the car would have a very slight miss occasionally when the lights where on but apart from that it ran fine minus a little power. Now to the issue at hand, a couple of days go I went to the shops and spent about half an hour there, once I came back to the car it didn't want to start. It would crank about 3 times as usual but it was like it just barely wouldn't start if that makes sense. It would almost fire but just not enough. I let it sit for about 20 mins after cranking it a few times and hey presto... started like normal(the engine,TCS and slip lights stayed on for the drive but car seemed to drive normally). Got home and turned it off and started it again within a minute or two and no problems 3 cranks and off she went no engine light nothing. let it sit fir an hour or so and again no problem starting and no lights on the dash, so I went for a drive for about 45 mins or so and stopped to get some food, again car started no problem. This morning on a cold start as per normal no issues, drove half way to work and stopped to get a coffee(normal routine) came out and again car won't fire. So I let it sit for about 20 minutes and it started like normal...hmmmm... drove to work(engine,TCS and slip lights on) car drove fine. Went into work and opened up, came back out and started the car (no more than 2 minutes since the car was turned off) no problems. so at lunch I started the car again and let it idle for about ten minutes again no issues. Turned the car off and about 2 minutes after tried to start it and it didn't want to start again.... car now stuck at work :(

I'm a noob to R34's so any help would be appreciated. The car is in Kensington VIC if anyone can help it would be great because I don't have a car at the moment and unfortunately I do need a car.

Thanks in advance to anyone that helps.

Pete

Hi that was the first port if call i checked the main battery wiring and earths , all looks good as an uodate the car decided to start and run for a bit today then died and started again for a bit and died again. When it runs it runs perfectly as in I can put a cup of coffee on the motor and wouldnt spill a drop (smooth). Luckely I managed through a friend of a friend to have it scanned today while it was running and it came up with low voltage, ignition and cas faults. I have a new battery for it comming tomorrow as the current battery doesnt want to charge. Will see if that changes anything.

In the mean time if anyone would have a cas sensor to suit the rb25det neo that I could borrow to see if that fixes the issue before buying one I would realy appreciate it as my funds are low at the moment and I need to get the car going asap.

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
