I though it might be handy if I added the ECU pins I intend to use;

Fuel Adjuster;

Red = 12 volts + * Pin 31

Black = 12 volts - * Pin 32

Green = input from AFM * the cut wire that used to go to Pin 54

Black = output to ECU (where the AFM used to be connected)* Pin 54

Boost Controller;

Red = 12 volts + * Pin 31

Black = 12 volts -  * Pin 32

Green = input from injector * Pin 101 (cylinder #1)

Black = output to the standard solenoid * the cut wire that used to go to Pin 104

I have now fully tested them and the connections are as posted above.:cheers:

Emanuelt,

I am referring to this. The pins may be different but, the idea is that the standard solenoid only gets its signal from the IEBC. (see 2nd last line)

Just bought the kits but now Im having second thoughts.

Car is R33 with 3" exhaust, R34 cooler and 10psi.

I know a PFC will be better but how much better?????

Say PFC $950 + $400 for dyno tune

= $1350

vs

Jaycar components

$140 + $200 dyno

= $340

I'm not planning on going bigger turbo this is the end of the mods. Is 170-180rwkw realistic considering my mods? Am I loosing a lot of midrange compared to a powerfc ?

I know a PFC is a lot better for tuning but I am hoping to get 90% results for a fraction of the price of PFC. If I was going bigger turbo I would buy PFC for sure.

Just read somewhere that 195kw PFC vs 195KW SAFC tune is a lot different? Is this true?

I mainly got the DFA to try and get the comp to stop going into Rich and retard and the car feels a bit slack around the 4000rpm mark...

Hopefully the DFA will improve fuel consumption a little aswell....at close to $1.40/litre! Currently get about 12L/100km, 10-11L/100km would be nice

On the dyno the car was going to AFR of about 10:1 on std boost. What is reasonable to lean it out to 12 or 12.5:1 presuming you dont get pinging...?

An A/F ratio of 12 to 1 is OK. For a standard turbo the DFA should be fine. You will have a slight compromise on the ignition timing versus A/F ratio. But it won't be dramatic. At 10 psi you will find the A/F ratio gets into the 9's, so 12 is a big improvement. Fitting the DFA to the Stagea gave ~10% improvement in fuel economy.

:) cheers :)

Nice...

Thanks for that...how about the DFA vs PFC argument for these mod levels..would there be much difference in say 0-100km/h times or seat of the pants?

I mean if the car is close to detonation and you are close to you 12:1 AFR the PFC cant really improve on that can it. Just has the benefit of pulling out timing when needed.

Sound reasonable or will you feel quite a bit more average power with PFC??

It all depends on how good the tuner is, plus every engine is different. So there is no way I could tell how much better it would be with a PFC. As I said in the previous post, a DFA and standard turbo is OK. Good value for money option.

Let's face it, you will be easily able to sell the DFA for more than it cost, if you choose to go PFC in the future.

:) cheers :)

Fair enough - thanks for all your help.

Give it a go..like you say could sell it if it doesn't turn out to be adequate. Where do you go for tuning or you just tuned it yourself on the dyno right??

I thinking BEL garage in homebush....quoted about $160

Dyno Dave and I tuned the DFA in the Stagea on the race ream dyno, took about 1/2 an hour. Simple stuff, once you get accustomed to the Controller buttons and how much adjustment you need ot change the A/F ratios.

:) cheers :)

Cool..

I think the SAFC2 reads out the knock levels on the screen. Is there any cheap way for me to take the output of the knock sesor and convert it to numbers you can read in the cabin?

What is the output voltage 0-5v or 0-1v

thanks

Do you want the knock levels for tuning or just for ongoing viewing?

Impakt (refer to the Group Buy section) has a consult output screeen that will display every sensor input and quite a few of the ECU outputs as well. Very usefull diagnostic tool that works on almost all Nissans.

If just for tuning. any decent dyno shop will have a set of "ears", there is no better knock reader than the human ear.

:) cheers :(

The Consult does not read knock, Impakt said that it is not available through it.It only tells you if they are working or not. :D

I am working on a Knock Reader which is tapped into the sensors, they seem to operate between 4v at idle, start up & cranking and drop in volts as more knock is detected.

This may take awhile as work is taking most of my time.

SK - As I still need to fine tune my IEBC I noticed my reading are up and down alot, I solderd up the restricter a bit so my highest input levels will be different of corse but maybe I should take the solder back out and have it like yours more. It mainly sits on 10psi but sometimes when the auto changes down a gear and really gets reving it can hit 14psi for a second before it settles down but reving it from the same gear it won't go higher than 10psi?

Here are the current readouts. Tuned on the road.

Any sugestions? (It only needs to go to about input 45, doesent go any higher when driving)

Here is what the people on the dyno tune had. My previous post is on LOW setting, this one is on my HIGH setting. Some RPMs the actuator fluters if you hold it in the mid revs. Must be becuase the setting are jumping up and down too much.

Wow, you sure have a lot of different solenoid duties. Mine doesn't have anywhere near that many. Maybe that's the problem, I don't have this sort of mapping;

13=18

14=22

15=25

16=30

17=32

18=32

19=23

20=16

When accelerating mine goes from load point 14 to load point 20 in about 200 milliseconds. That might be what is causing the flutter, 16 (load point 20) is half the duty cycle of 32 (load point 18). That's a lot of reverse (higher load point, lower duty cycle) solenoid activity.

In an auto you will get a slight flare in the boost on gear changes as you don't lift your foot (like you would in a manual to change gear) so you don't get a change in the injector duty cycle. I don't believe it is a problem as the standard ECU cuts/interrupts the ignition on the gearchange. The extra boost doesn't translate to extra load.

:( cheers :D

Just building the hand controller at the moment. There are 3 links (one under the D25 socket. They were not provided in the pack. Are they meant to be just bits of wire?

Also are you meant to fit something uder the other side of the LCD connector (washers or anything) - it angles down a bit

the wire links are just parts of the wire that is given to you, otherwise just use cut offs from the resistors/capacitors etc that you have made...bend em in shape

as for spacing, my hand controller is pretty dodgy...i have to solder the button holes bigger.

If you want it to sit flat

get some solder, melt it and hold it on the end of the soldering gun..then align all screen and just tac solder the thing in at two ends, then solder all the remaining areas...thats what i did, turned out fine....

Did yours come with it?  I guess I'll just find some somewhere...

Thanks

PS How about the LCD screen...did you put spacers or anything under it?

There are plastic spacers in the kit.

:D cheers :D

    • 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.
