Hey guys i have two questions.

On a Z32 ECU 8 bit type suitable for nistuning to suit ECR33

1 does anyone know the resistor value for R141 or someone be so kind to measeure its resistor value or a schematic or know where i can get one. (Need schematic not pin out)

2 There has been a wire link mod done on the bottom side of the ecu that is not in the required modifications list. Its between the pin above c53 and the 5th leg down on the lefthand side of the DIL chip that the c53 pin resides in. (see pic)

Is this on anyone elses nistuned z32 ecu on a series 2 r33 or if anyone would be so kind to measure the resistance between these two pins?

cheers

Patrick

Patty I would jump on the nistune forum

Or maybe even email them

That would be the best info

Thanks man the guy i bought it off must have had a s1 motor in his series 2 ffs!

Haha sucks big time!

But when I was searching for info about mine I just jumped on their forums and found heaps!

Way better then the hoons on here :O

I'm running z32 ECU on my S1 and I have done the necessary mods but I have not come across this wire. Not sure why it's there. As mentioned above, Matt over on the NIStune forums will be glad to help you out.

As far as the resistor goes, if you go to the support page on NIStune.com and then installation documents, there is a z32 RB25 ECU modification document that will go into detail about the resistor.

Thanks for having a look much appreciated. The documents specify resistor values when using them to attunuate/alter signals but since this resistor is simply removed it does not specify the value. I will stroll through the nistune forums.

The wire link may have been done in a previous modification revision or an alternative way of performing one of the modifications or repair.

Thanks again for taking the time to look.

Cheers

Hey mate.

I'm doing a similar thing... checking a used one that i'm going to put in my S2. It looks like mine was done a while back, with the knock sensor pins 23/24 joined instead of stubbed out etc.

My resistor 141 is a 3-band red black brown (no multimeter on me ATM, but you can work out the value from the colours). Looks as big as the rest on the board, probably a quarter-watt.

What i'm looking at now is the fast idle control, which is supposed to be pin 33 on the Z32 and pin 36 on the S2 wiring, but the latest Nistune document just says to cut the track of 33 to stop the light coming on the dash for a false exhaust overheat warning. I'm thinking that it would be wiser to jump 33 over to pin 36 to retain this functionality. Perhaps this step is further down in the guide... one page at a time.

      RB20 in need of modest love injection

      By GTSBoy · Posted

      As you're looking at using a Link ECU, then large injectors are not a problem. But there's not really any need to go 1000s on an RB20 unless you're planning >>600HP on E85, which would seem unlikely. There are other options for injectors. The Xspurt ones are available from a number of places and you can get them in the mid 600s and 725cc, which is probably a sensible place to be. These are all EV14 based. If you are not using the stock AFM (at all, which would be the case with a Link) then a large turbo intake pipe to suit the ATR turbos is not an obstacle, so you should use one instead of a highflow. Results will be better.

      RB20 in need of modest love injection

      By QB6SAGR · Posted

      Hey guys,  I'm after some advice and this here is the best place to get it imo. I was a member a looong time ago under another account, with a lost email address. Its nice to jump back on and see some of the same names still giving good advice.  I mothballed my car when i moved to perth in 2013, and after getting towed across the nullabor a few times it has officially done more km's on a trailer than under its own power. Now that i have started the process of tidying up and modifying it, i see the fruit available (and the fruiterers selling the produce) is different than back in the day. hence my questions, as i used to 'know' what to get and now, i'm not so sure. Engine wise the car (92 gtst) has a walbro 255, k+n, fmic, cam gears and and turbo back 3"exhaust. Wish list is a Hypergear high flow or ATR43G1, Link G4x and some newer injectors before a tune up. My goals are modest, only low 200's power wise. i know i could achieve this with less, but i've been swapping out old for new where i can. Every cooling hose has been replaced, along with mani gaskets, WP, thermostat and radiator, fuel pump and timing belt, tensioner and idler, and i rebuilt the steering rack. Regarding the injectors, the fruiterers all seem to sell what used to be considered quite large injectors. There are a lot of options for bosch 1000cc EV14's, and i would like to know if that is a suitable choice for my build. Is modern injector design good enough to run these at the low duty cycles that i likely would be? is there a downside to running a too large injector these days? or, would there be an upside to running a smaller injector at higher duty cycle? I can see that there are smaller injectors still available, but the ones i have seen specifically marketed for RB's are pretty large (see: https://golebysparts.au/collections/fuel-rail-injector-kits/products/nissan-rb20-fuel-rail-bosch-980cc-1150cc-injectors-turbosmart-fpr800-regulator-kit), and i dont know enough about them to say one not marketed for RB's would fit or not. I have searched the forums, and amongst all the posts on older tech, I did see gtsboy recommend EV14's, but no size was mentioned... again, i'm not clear on if the smaller size bosch injectors are also EV14's as they do look similar.  also, if someone can recommend a tuner familiar with RB's in the Geelong or West Melbourne area i'd appreciate it. Thanks in advance guys. Cheers, Rowdy

      R33 GTR lift points for hoist

      By Duncan · Posted

      FWIW the depth of the groove in the rubber pad is not super essential, the blocks are rubber and squish a bit. If you are worried an angle grinder will make a deeper groove quick smart

      By GTSBoy · Posted

      I mean, if you were to move the jacking points away from the original location, that is, away from the wheels and closer to the centreline of the car, then it will be more likely to overbalance and tip off the supports. Same as we talked about before. I was talking about moving for-aft. If the sill is bent outward or inward, then the car would obviously look unstraight from the outside. Hopefully that hasn't happened either. Again, you can do comparative measurements from the chassis rails to see if there is much deflection.

      Can you elaborate what you mean with your first sentence? I meant move as in the bulge kinda seemed like it got pulled "outward" meaning it got pulled down and to the side with the jacking rail itself, so the load bearing bulge now sits lower than usual and is not level with the sill on the other side of the jack point. Either that or the jacking rail just got pushed in a good bit.
