From the PowerFC FAQ (in my sig)

Can I drive around without it being tuned for a few days? Months? ?

You can drive the car around as you would normally but you should take care not to put stress on the engine. Basically don't fang around in it, as you could be running unsafe A/Fs etc and just causing more damaged. Best to get it tuned. Make sure you watch the knock levels if you do this to make sure there isn't excess detonation.

What about with nismo 555cc injectors and z32 afm? will the car still be able to drive around on the base map? im thinking of driving my car to my tuner (1 1/2 hours) will it still drive fine and be safe? or should i put it on a trailer instead.

Also have another questions (sorry to hijack your thread Kaige) should i install the 555's and z32 after i have done the self idle learn procedure with the stock injectors and afm, or should i install the 555's and z32 and then do the self learn idle?

Cheers

my recommendation would be to reset PFC

turn key to ON but not START

then dial in correct inejector setting and afm

then once done turn to START and do self idle adjust

So do the self idle learn with the nismo 555's and z32 afm?

yeah i would do that if it was me

just make sure you selecgt the right AFM, make sure its a genuine z32 and make sure you dial in the right latency and correction for the injectors

Awsome, ill give it a shot when my injectors and afm arrive, by the way do you happen to have the correct latency and corrections values for when i upgrade the stock injectors to nismo 555cc's, i worked it out a while ago but have lost the peice of paper i worked it out on :P

Thanks for the help.

Ok, so ive worked out 66% for correction (please correct me if this is wrong), but i cant seem to work out the latency, im guessing i need to find out the latency off the nismo 555cc's and then subtract 0.528 msec for the stock injectors to work out the latency right?

    • 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  
    • 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
    • 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.
    • Is it alright to top up with just another green coolant?
