i have a remapped ecu for sale. it will work in both series 1 and series 2 manual r33s (for those that think the series 2 have the ignitor built into the ecu, they don't). the person i bought it off had it in a series 1, and i had a series 2 motor in my car.

i tested the AFRs at 11psi on standard turbo, fuel system, with just a turbo back exhaust, pod and fmic. at full throttle they from 12.5 from about 3000rpm and slowly drop to 12.0 by about 3700rpm untill about 5500rpm when they start to drop to 11.4 by redline.

the ecu has had rich and retard removed, speed limiter removed and the rev limit raised to 7500rpm. i ran it in my 33 for about 8 months and never had any problems (on 14psi they go a lot harder than on 11psi despite what people say - most of them have never tried it and are only going off what other people have said). i never got to test the afr's at 14psi because the day i had a lend of a wideband o2 sensor the boost controller stuffed up and wouldn't let me go above 11psi. but when i pulled the spark plugs out after 6 months there was no sign of pinging or running lean at 14psi.

i was going to combine this with a safc to get perfect 12.0 afrs but never got around to it and no longer own the car.

asking $200 + $10 postage (or you can pick it up if you want).

located in gympie, qld

didn't have it on the dyno. just had a lend of a microtec wideband o2 sensor. at the same boost level it made a slightly noticable difference, but the fact that you can wind the boost up means you can boost up to where you would normally hit r&r and then really have some fun.

hi am i right in assuming i could just replace my ecu (series 1 r33 gtst manual) with this ecu and achieve instant power gains over standard?

a small gain yes. i noticed a little bit of a gain. as for an exact figure i'm not sure as i never put it on the dyno with this ecu.

      Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics

      @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
