woopsy time to upgrade to these eh
now its black diamond grooved discs with black diamond FT predator pads
baquete talked to me bout my dizzy position for using my turbo map on his setup.
i forced 15deg timing in datascan, idle goes upto 1100rpm, the pulley is at 0deg TDC so the dizzy was maybe -15deg too retarded before the remap?
back to normal 850rpm, the consult says -5deg, the pulley says +10deg, so the real ign timing at idle here is um -5deg?
maybe the different rev's affecting the result so i shoulda lowered the rev to 750 on both occasions before measuring the pulley timing.
hmm makes sense since the response time of the ign system is fixed, the crank rpm will affect the position of the pulley once that strobe flashes
mine,s set at 10 deg btdc paul, but i could,nt hear any det at 15 deg either (but i set it back to 10 just incase )
If you force it to be at 15º, that means on the whole map or just for base timing? But by the looks of your dizzy i would say that is very retarded and 0º is possible...
The "problem" is that Paul's dizzy was retarded when the map was done, then the whole ignition map was set to that base timing (more ignition advance to compensate). I can either pull the dizzy back or change the whole map to less 15deg...
ok just refuelled (my local shells been milked dry and ended up going to the nearest motorway service shell)
i've been running an idle of 850rpm for awhile, prob to reduce vibrations at 750rpm and prevent stalling under PAS load, which makes the timing at 850rpm become 5-7deg.
so i reduced idle down to stock 750rpm the consult timing goes up to 15deg.
i force 15deg via datascan, the strobe reads 2deg, the dizzy is 13deg offset retarded.
turn off active test and consult reading stays at 15deg, again pulley reading 2deg.
so there u go baguete, my dizzy is bout 13-14deg too much retarded
Ah, thank you one more time.
I think i will aim for 15º total retard on the dizzy because i will run it with RON95, even with a lower CR using a thicker metal HG (1,75mm) i should reduce the chance of detonation.
its only because you have used 2deg btdc (instead of 15) as your base idle setting when the car was dyno,d surely paul ?
but if the map peramiters only extend to (for instance) 45 deg btdc, and you need 55 deg, you can shift the base idle to achieve the 55 deg eh (and lose 10 deg at the bottom end obviously)woulda thought at idle it should run the same as stock cos the c/r, airflow and other parameters would be similar, its just using different maf sensor and fuel system
like when i uploaded the stock 1.3 map & aligned the dizzy position, it idles and responds to pas exactly the same as stock
lol paul you have the patience of a saint, would it be easier to datalog it through the gears, then analyse it ?
How's your new LSD holding up Paul? I'm keen to know how it behaves/compares in comparison to the original build spec
I just send a mail to gripper requesting some information /answers on the supplied standard K11 setups.
