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..

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
