Hi Everyone,

Mate of mine has built a 1000hp rb26dett and is in the process of installing it into his r32 gts...currently he is nutting out the loom and electrical side of things and wanted to know if he needed to run the factory resistor pack for the injectors? Not sure what injectors he is running, obviously something big enough to support 1000hp :P...if its important I will ask him and post it up.

Thanks to anyone that can help. :ninja:

Cheers!

Depends entirely on the ECU he is using and the type of injector drivers that ecu has.

Ecu's that can drive low impedance injectors without a resistor pack can potentially run lower pulse widths as the injector driving current is controlled more precicely. Most if not all big injectors are low impedance and would require a resistor pack if your using a power fc or something simular.

Hi GTRNUR,

He is using a Link Plus G3 ECU to run Siemens Deka 850cc injectors, here's an excerpt from the ECU manual on injector drives:

The LinkPlusG3 has eight independant injector drives allowing sequential, sequential staged, group and group staged fuel injectors.
These injection drives are designed to be used with high impedance injectors, injector ballast resistors must be wired if low impedance injectors are to be used.

So I guess he just needs to find out if the Siemens injectors he is running are low or high impedance, if they are low then use the factory resistor pack?

Cheers!

Turns out my mate wants to try and accomplish this a bit cheaper and make the resistor pack himself, does anyone know what resistors he will need and how many? (one per injector maybe?)

He's found a place in the US that sells the factory resistor packs for about $180 (not sure if AU$ or US$), does anyone have good condition one for sale that he might go instead? Otherwise I think he'll try and go the above mentioned route to save some $.

Cheers!

Not directly related but I was speaking to Ray Hall this morning about ViPec V44's and peak and hold injector drivers .

ViPec market a peak and hold driver box for the V44 because it comes with low current high impedance injector drivers .

I'm not sure if Link do them and the real question is whats cheapest , large high impedance injectors or peak and hold ones with the driver box .

They can be sourced new from Nissan or plenty of second hand ones or he can get one from a wrecker out of a MR30 (exactly the same as the gtr ones) or make up his own.

I used a gtr resistor pack the first time and made up my own the second time (purchased the 10ohm resistors from Jaycar) the ones you are after are the LARGE 10W/10ohm resistors and roughly $2 each :D

Hey Mate

I purchased a 6 ballast resistor pack for NZ$105 from NZEFI: http://www.nzefi.com/

I think Link themselves sell them for around that price too whick would work out to around AU$85+ Shipping

Probably just as easy to get the Vipec one as they should be around the same price

Good luck

Dan

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.

      The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.

      One way of putting the fuel surge idea to rest, is that even when in neutral/clutch in or free revving it still has the same issue, it can’t even get to limiter (7800) so to me that says it can’t be g force, I’m not trying to argue I just want to find the f&$king issue 😡
