nah sam, 1st time there if i remember correctly. something to do with the fact that since his ebc wasnt working properly the was allowed to drive off without paying a cent but will pay full amount when he get a tune with a working ebc. wierd.

nah, its still here. i cant get the work done until i can borrow my sisters car. shes on holidays atm. so once shes back at uni, i'll drop the skyline off and borrow her pulsar.

are you still in the process of gathering parts?

i drove it a few times. Gearbox is very funny in terms of shifting to say the least. But it has tidal waves of torque compared to the line. s2000 is a different story - it has an awesome gearbox. Shifting is go slick and fun in that car.

Bachelor of IT.

I'm in my 3rd year so yer exams suck. :(

Especially J2EE - Internet Computing.

I'm a fiddler. I only 'try' to improve upon the current cheap $100 tune I had.

I found that when changing gear or simply flattening it the map trace was dipping to load point 20 then once accelerating settling on load point 19 through the rev range.

This load 20 point was running ever so slightly too much timing as it was causing highish knock readings.

I reduced load point 20 by one degree and left load point 18-19 the way it was and knock went from 35 down to 17.

So.. I dialed in another degree in to load points 18-19 and found knock didn't rise.

That 1 degree makes it feel more lively, but only makes throttle control that little bit harder in second.

Basically through the mid range its now running 17degree's instead of its previous 16 and in some parts 15.

These new tyres don't hook up though. :)

I bought some Firenza ST-03's.

If I don't ease my foot in to it second axle tramps majorly. :D

My subframe bushes are screwed, first things first during the holidays, I'm going to fit some pineapples, hopefully it will stop the subframe from slopping about and help with traction a little.

If I still get too much movement, over the X-mas holidays I'm going to drop the subframe and fit a set of new subframe bushes from Noltec ($190 from Unique Autosports).

Maybe, a big MAYBE fit a S13 3.9:1 diff as to help the rb30 get that little more speed from each gear.

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
