Nistune

[Rolls]

After more discussions with the tuner, he called Matt and the reason behind the drop in communication is that there is too much electrical noise and the ECUtalk cable is the issue?? Tuner mentioned that it took him 30mins to change one section of the fuel map in between drops in communication... Now Matt suggested another cable probably the plms? one ($100) and problem solved. I paid $80 for the ECUtalk cable and it has, and I quote the tuner, taken 13hours on the dyno to get a raw tune!!!

I can't believe this shit... Needless to say the car won't be ready until Monday when the cable gets here and I swear it better not take long to get the final tune on it!

It took your tuner 13 hours to realise that the cable was dodgy? He better not be charging you the $200 an hour you quoted for that!

Probably 13 hours is the whole time added up so far which seems excessive

Initially they had write issues because of board installation probs causing errors, and after that the invalid license stopped further tuning, and after that problems with the electrical noise slowing the connection. He was trying to tune whilst it kept slowing down/dropping out because we didnt realise it was having noise issues. Trying to diagnose over the phone can be a bitch ...

If everything is done properly then there are no probs, but this time around has been multiple points of failure with the setup

It will be interesting to see how it goes with your nistune cable, i have one of yours and it is perfect everytime on every car. The only time ive ever had issues is with a 3rd party cable when out helping mates with home tunes etc...

i would bet it is the "other" cable causing issues.

I am using the BLAZT cable (I bought that before I was even thinking Nistune), it works but has issues every now an then.

So when recording a longer log it is mostly a matter of minutes till the connection gets interrupted.

I would recommend buying the cable from Matt, it's money well spend and saves you much headache ..

interested in getting a nistune installed/tuned on my r32 gtr

who in sydney is most reasonable with prices ?

[SiR_RB]

CRD wants around $1500 installed and tuned

CRD wants around $1500 installed and tuned

That sounds excessive. I got my nistune supplied, installed and tuned for 770 in my r34 GTT. Dunno if the GTR's are a lot harder to do? Also depends on mods you have done i only had the basics such as FMIC, turbo back exhaust and boost controller

[SiR_RB]

hmmm

as for my performance mods go, only got aftermarket exhaust front pipes, 3" hi flow cat and catback, air pods and profec b @ 14psi...

if anyone knows a more reasonble place in sydney please let me know !

cheers

In before Yavuz @ unigroup

Yeh much the same as me, I got mine done for $550, bought the board for $200 so all up was $750. But my tuner told me mods won't affect the price at all unless they are done badly.

Depends on the value you put on your engine, CRD are known to do good work and can charge accordingly..... Tuning is a fluid thing and can be done good bad or everything in between and the prices generally reflect that.... it also keeps the shit out of your shop.

[darkhalf]

Agreed - tuning costs are also based on time spent. Doing the mapping for a quick power run is obviously going to take less time than carefully going through everything including idle and off boost drivability

With regards to cables swapping the customers ECUtalk cable for a PLMS one was reported by the tuner to work perfectly afterwards with no drop outs

Last week we put my R34 GTT on the dyno (just got cams fitted... squeezed 301rwkw @ 18psi out of the GT3071R) and was running with a blazt USB cable. We were experiencing several disconnects in the higher rev ranges, so swapped in the PLMS cable and no more dropouts on subsequent runs

I just have to point out that most of the cables out there were based on the original serial version PLMS schematic that was made available to the public and then add a FTDI USB converter chip on top. However Pete has spent many hours since on the dyno and using scopes etc to monitor, isolate and filter the noise which is why there is a significant improvement with data stability in the later version USB cables which have come out

Whilst most cables will work fine for your normal consult display apps (apart from ROM download) where data integrity is important, there is a requirement for nice clean comms signals from the consult port (this includes good grounding on vehicle also)

Hi people,

I've got an R34 GTT tiptronic and want to get a Nistune board and a proper dyno tune. The catch is, I am also looking at doing a manual conversion later on.

Can anyone confirm if a manual conversion requires an ECU swap? Or can the car be run with the auto ECU with just the auto 'logic' disabled?

And what's the go with Nistune, I understand the board is not transmission specific but what about the tune? If I was to retain the auto ECU after the conversion, would the board or tune need to be tweaked to support the manual box?

Thanks guys.

[darkhalf]

Dont see any problems still running AT image on the board with the manual trans, except you will get AT fault codes.

Since AT/MT should have no difference with fuel/timing maps etc (Trent correct me if I'm wrong here) then tuning shouldnt be affected

Other tables like injection limits, fuel cut/recovery will be different between AT/MT

I would suggest when it comes to MT conversion to get the board reflash the board to a MT image and copy the main maps over from the AT tune

Anyone know good places on the gold coast / bris to get a nistune and a tune from?

Awesome, thanks Matt.

So it sounds like I should be able to continue using the original auto ECU and the Nistune board after the conversion, and just get the tune tweaked for manual transmission? Sweet!

[SiR_RB]

Can it support rb20/rb25 air flow meters for a gtr?

My goal is around 280 - 300awkw relisticly by next month

[JonnoHR31]

nistune can, yes

[DuFFR32]

Is my ECU nistuned? lol weird question I know but apparently my ECU is... here is a pic of it. Dont know what the board is on top of the unit upside down?

I also need to know who does nistuning around gold coast area or north coast my car is running like a 3 legged goat atm

[aleks]

No it doesn't have a nistune. I has been chipped though... Its got a socket with UV eraseable EPROM
