Dam straight Damo would rather do SAU them heroin gts4 are 4.1 because they share the same parts from the gtr i think r32 gtst is 4.3 because of the lack of torque from the rb20

ryan, my PFC doesnt display boost :thumbsup:

simon said thats not avail. on the rb25 version :)

as cubes said, cheap map sensor will sort that out, i bought the proper adapter.

yeah +1.

Also important to note the ramp rate the tuner is using......Shoot Out Mode (200) is a waste of time for the street, should be 150 or it will definitely run in different areas of the map (detonation city) on the bitumen and up hills.

definetly pete, 150 is our default ramp rate. depending on the style of power delivery but yea mainly 150. We sometimes lower it for just 1 run to really load it up to simulate going up a hill just to be safe.

just had Ryan n the guys at AUSSIE DYNO N TUNE tune my car today had a few issues with wheelspin but after putting ryan in the boot gave it a few runs and pulled a constant 300rwkw then on the last run pulled 327.4rwkw on only 19psi with only 18 knock level!!!!!

great guys down there fully reccomend them 2 any1!!

great talking 2 u Ryan top bloke, ill be back there with sum softer tyres n maybe biggr injectors so we can screw sum more boost in2 it maybe.....

hmmm, I might have it the wrong way around Ryan.

Is there more load (or brake on the rollers) at RR:020 (20kph/s) or RR:015 (15kph/s)

The higher the ramp rate the less load the rollers place on the car.

Then there's start speed, release time, end speed. Basically there is a whole lot of different combinations you can chop and change to suit the car and what sorta load you want to place on it. If a car is placed under light load but does a full power run, The true AFR reading will be false to a certain point as with power output.

hope that made sense lol.

yea sorry i didn't answer your question... rr:020 is a higher ramp rate therefore giving less load on the car...will show a slight increase in power. At the end of the day its just a figure. The dyno is purely a tuning tool. Unless your simulating near bang on road conditions then AFR's and power will not be accurate.

You were bang on the money pete. :thumbsup:

If for some reason you do need to tune with a higher ramp rate, eg. Wheel spin etc.. then a bit more care has to be taken with the tune and must be alot more concervative. So many other factors come into play.

yeah, I know Donan has changed his methods a bit over the years.

These days he tends to keep the AFR's on the lean side (around 12:1) but pulls extra timing out to compensate, up to 3 degrees (from around 20 to 17).

That's why I'm keen to get those adjustable cam gears happening at some stage so I can play with the valve timing a smidge as compensation for lost ignition timing.

One thing I like (and contemplating) about a decent set of cams is that they would dial out some compression due to the extra overlap and therefore allow me to keep my ignition timing up.

Anyone know someone selling a car for under/about $2500 with enough room for putting a wheel chair in the back ... like a wagon or R31, something with a big boot. Must be auto also :thumbsup:

just thought id post this,

fellow bmxer Matt Duncan lost his life in a car crash early this morning in Stirling North, just out of Pt Augusta.

i got the chance to ride with him a few times, and he was a shredder, always killing it at whatever he wanted to do.

RIP.

took off my brakes today. Fronts are only 2pot and rear is 1 pot. :)

Brembos have arrived tho :) awesome condition, but the bolt sizes are different :(

Just have to get some braided lines and get them slotted.

      S1 rb25/s14 starting problem

      By Duncan · Posted

      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

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      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

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      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

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      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.
