well, i first searched for this, but i couldn't find it
maybe one of the more seasoned members could direct me

i going to be installing a greddy kit in two weeks or so
depending on time it takes paypal to refund my money,

background^^^^
lol

anyway

in the greddy instruction manual for the turbo kit install
on the last page,
seen here https://www.miataturbo.net/forum/showthread.php?t=852
"before driving
ignition timing should be retarded 4 degrees to a final setting of 6 degrees
before top dead center"



now, i have changed my own clutch (in the 91 civic and my 92 miata)
swapped axles,drive shafts, all that fun stuff
so i feel confident to say i can install my own turbo kit from greddy
but im scared to death of timing



can some one

1. give me an extremely detailed guide
2. direct me to somewhere with lots of pictures

so i can retard my miata 4 degrees

Just to be clear... the entire CAS assembly will move. There's one bolt on the back of it that you can see in the pics in the link above. Just loosen the bolt slightly, and very gently (small increments) rotate the entire CAS assembly. It's not hard, and there's nothing you can screw up.

on a side note, i have the bipes acu sitting in my room

will i need to retard my engine if i use this nifty device?

Braineack

no, advance it if anything

I ran 14 degrees BTDC with my bipes.
IIRC it will only pull a total of 8 degrees so you may just run 12 degrees if you don't have an intercooler.

this whole timing thing makes my head hurt lol

ok, so i gathered that i need to rotate the crank angle sensor
to adjust timing, which way do i turn it?
and how much?

will retarded it 4 degrees be sufficient for 5lbs

Bryce

iTrader: (24)

Retarded 4 degrees from 10 BTDC will be enough. That would be 6 degrees BTDC.

Just find out which way you need to turn it by turning it a little then checking the timing.

i just re-read what i wrote, i sound like im the one thats retarded lol

alright,
so i just need to mark the pully,
get a timing light,
and then adjust slowly,
thanx alot

if you do the bipes then there is no point in retarding your timing. i would possibly advance it on the car like brain- said then put the bipes on and have that system retard it back down to a certain degree.. if that makes any sense... if not just do the bipes. IMO

Dont forget to use a jumper to keep the ECU from trying to readjust it while you are setting it. Remove the jumper when its done. At least that how mine works. YMMV

Braineack

yes. it's how you have to do it. GND and TEN, keeps the ecu locked in at 10° advance.

Come on Man, did you go to the link I posted? Your post tell me that you didn't even bother. The instructions there are idiot proof! Here's a Mr. Potatohead version:

You don't have to mark the pulley... it's got a mark already on it.

Do this, in this order.

#1: Jumper 10/Gnd
#2: Start engine, once warm, adjust idle to 850 using idle adjust screw.
#3: Connect timing light (ground/12vlt/#1plugwire).
#4: Aim timing light at crank pulley and check timing... little dot on crank pulley should be at 10* if stock.
#5: Loosen bolt on CAS slightly... probably less than a turn will do it.
#6: LIGHTLY tap on CAS with wrench or grab with hand and rotate the entire assembly 1-2mm.
#7: Check timing at crank pulley.
#8 Repeat step #6 until set at 14*.
#9: Tighten CAS bolt, stop engnine, remove timing hookups, pull jumper, close hood.
#10: Connect Bipes to ECU wiring harness under passenger footwell.

Initially, set Bipes to pull 8* total, starting at lowest RPM, and minimum extra pull for temp (for winter). When summer comes, set to maximum extra pull for temp.

Now get to a dyno, tune you AF's, and adjust your Bipes (by listening for knock and pulling less timing). With 6psi, you can probably get away with only pulling 6* total. If you've got 93octane and run a little rich, maybe even 5*.
