While on the topic just a quick question because i can't be bothered searching through 100 posts. You can't run an RB20 remapped ECU on an RB25 Series 2 because of the internal ignitor, correct???

Hm... ive never heard of this problem... keen to hear more also.

Pretty much what i remember reading a little while ago is because series 1 has an external ignitor for the coil packs and series 2 doesn't, a remapped RB20 ECU wont run on a series 2 unless you run an external ignitor.

Hmmm i guess i might just do some searching.

Another guy in another thread posted that, r32 ecu was straight plug in.. Only concer is no VCT support..

quote:

no probs what so ever, plugs straight in, however the 20 ecu cannot run the VCT, was no real issue for me as with the remap done, timing changed, boost raised it still has bucket loads of torque down low anyway!

Getting full boost at 2500 rpm, makes 215 rwkw on 0.9 bar with stock turbo. Drives like a dream, smooth clean power with awesome responce!

Hmmm, the reason i asked about the RB20 ECU on a series II is because one of my mates is a tuner and has a spare RB20 ECU that he could put an RB25 map on and tune it for me. At the moment my car is hitting boost cut/ airflow cut (whatever the hell you want to call it) at 4000rpm on 1 bar of boost on my HKS turbo.

I have 2 options that are possible to do at the moment:

1) Modify a standard actuator to fit the HKS turbo instead of the HKS adjustable actuator and run less boost to avoid the boost cut.

2) Remapped RB20 ECU to get rid of the boost cut and be able to tune it.

Now i know that a full ECU replacement is the best choice, and i will be doing that in the future, just dont have the funds at the moment so im looking at only the 2 above solutions.

So yeah thats my problem at the moment, if i can get the RB20 ECU to run on the series II its going to solve the boost cut problem, because at the moment its giving me the sh*ts.

I didn't know nistune could do the R33 stuff yet.... hmm might have to chat to Matt...

We use daughterboards and real time emulation same as we have on the RB20's for a couple of years now :)

i just heard that they are testing.. it was on their site. They will need someone to test it for them lol

I think if you remove the kick panel and lie it on the floor, it won't be standed anymore.

ROFL....i kill me !!! >_<

:laughing-smiley-014: the lame/funny approach to being a spelling nazi :thumbsup:

if your in sydney, i've heard hills motorsport does remaps for r33 gtst's for $350

These are the simple plug in chip upgrades, and to the best of my knowledge CANNOT be tuned in real time, and also require purchase of a new SINGLE USE CHIP every time you want a new map loaded...

The method we are using is converting the R33 to run a single 27C256 eprom, which can be re-used, as well as tuned in real time with full map tracing etc etc... Hence, the initial $$ are a bit higher, but the end results are WELL worth it.

hehe yea the $$ is scarin me a little.. But i might be a guinee pig and try it out..

so when did you say you are coming to sydney?

Also you got any dyno figures sam? just to see what a similar rb25 with basic mods can acheive..

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
