Everyone loves a picture.

Timing logs off my own car.

Without a crank trigger.

With crank trigger.

Probably worth mentioning that it's not essential on all RBs. For instance mine with the stock CAS is about as accurate as your trigger set up

I don't understand how some can have issues while others won't, even with the same setups, .. I want to upgrade ECU but am fearful of timing issues, so don't know if I should go for a trigger kit from the get go even though as you say it's not essential in all cases

I hope something like that with all the mass at one side would not cause issues at high rpm? The design is a little different than the others I have seen. Would it still work with vct?

Hi,

I thought the same but then I looked at some other kits that just use a longer bolt in the position of the adjustment bolts on the cam gear which weighs about the same as this 1.6mm rolled steel.

I welcome professional feedback :)

Cheers

The issue with using a disc is the centre if the cam gear is set back from the front.

Not a problem. Two piece centre, with a shim/washer behind. Spot weld together if paranoid, or make it out of 3mm sheet instead and machine some thickness off the bent up arms afterward.

The 2mm gap is the detection range and the finger needs to within the 2mm

This is what I was talking about, mine on my setup didn't read correctly till we got it out to exactly 2mm, any less and it would miss teeth, @ 1.1mm it would miss upto 9 in a roll at cranking speed, my ECU has a built in oscilloscope and that is how we found this issue

You only having one finger to look for probably won't be an issue though

It isn't volume it needs to be same moment of inertia. I=m x r x r where m is the mass in question and r the radius of the centre of the mass.

To work it out treat the bent up tab as one piece and the other section as a second piece. Add the results together.

    • For sure the later RB26 variants had a different setup (6 cam voltage sender?), but the RB25DE/DET share the same ECU pinout/PCB footprint, and at the ECU plug it ends up being 'throttle sensor in' & 'throttle sensor out' (to A/T TCU) ...you stick a multimeter on these pins and you'll find them directly connected (0 ohms) ; I had an pair of Nissan ECUs on the bench long ago, and I noticed this throttle sensor in/out link, actually linked to an op-amp ...which was unpopulated on the NA board, but present on the T board and I went 'ah-ha!' in some moment of clarity... ...it wouldn't surprise me if they changed strategy here though (in the software and actual monitoring of this signal), because they did with other stuff (A/T signals).. and 0.45v as a trigger point makes sense, as that's what the external TCU units expect at idle ; kudos, thanks for that insight...I suppose it boils down to whether or not Consult can display real time data of that signal's voltage... ...in any event, it presents the same target...ie; rotate TPS unit to achieve 0.45v to suit both ECU&TCU, and where do you goto from there? Just disconnect TPSwitch connector and/or that plus TPSensor connector....or do you go for the throat and disconnect IACV solenoid and see if it still stalls? (probably throws a recoverable fault code and goes for default idle strategy?)...
    • I’m also conscious that e85 is slowly being phased out. Not all United’s have them anymore. Can’t take the risk of being low on petrol and assuming the servo will have it. 
    • MR HAMMER has said his piece. Painted up to avoid Rusty Rusty. Actually lines up well. (i.e it lines up the same as the unmolested GTR guard). Turns out the GTR Strut brace does foul on the bonnet vents ever so slightly. May need a little bendy bendy if intended to keep using with a strut brace. So spacing it out to clear the FAST102 is not an option. Annoyingly, the bonnet vents also foul on the heater lines running over the engine. Given this engine does not EVER require a heater, a delete loop is going to be used. Don't worry, the defogger uses the AC. The heater is basically "Do not use the aircon and turn the fan on". It will still be effective, I promise.... once I get the system regassed... Will have to revisit with unvented bonnet I suppose, and suitable strut brace. There's plans to do this and other things tonight and bleed brakes (there was a weep) and put the bumper back on, and take Good Friday morning - Because troubleshooting on the side of the road limping it home at midnight tonight is ... not very smart.
    • Thank you all for you assistance. I contacted Nistune regarding the support for the RB20DE along with my ECU Code (23710-10U00). They do have a map for it and added the RB20DE as a purchasable option now as well. They also added Malta as a Billing and Delivery options as this was missing. I was honestly amazed at their quick response and action, it took less than 24 hours. I also looked again at direct fit options for injectors, just in case I were to replace them. DeatschWerks seem to use a Bosch EV14 base and makes ones that fit mine at 440cc lowest, but also have 550cc at the same price. I tried looking for other direct fit options and managed to find one (also Bosch EV14 based) which includes a plug and play adapter on ebay. Did a small test with a Noid Light on the troubled injectors and all seems good, so they are pulsing properly electrically. One weird part is that they are missing on the same two cylinders as before I got the injectors cleaned. Mechanic also found this weird as he did not label the injectors and it is unlikely to have the faulty injectors be installed in the same cylinders.
