how do you properly set timing on a 16V with digi-1?

[kpgli84]

ignition timing that is

i have heard to warm up the car to operating temp, unplug the coolant temp sensor and set timing to the mark on the flywheel, i have also heard of setting it with the engine at 2500 rpm.

what is the proper way to do it?

Thanks

You have to set it at idle, but because you have digi-1 Im not sure what RPM would be proper. As the RPMS increase your ignition system also advance the timing. So settin the timing at improper RPM can cause you to set the timing incorrectly.

For a stock 16v the timing is to be set to 6* advanced at I think around 950 RPMS when idling. Its in the bentley, I cant recall the exact RPM.

For Digi-1 I would assume you would have to set the timing according to a regular digi-1 car because the ignition maps are different. A good place to start would be to find a corrado manual and look it up in there. However, because its a different motor you may need to adjust the timing settings accordingly and I have no clue what those may be... but I am sure someone on here will come on who does!

Typically all ignition timing is adjusted at idle, and you check for proper advance at higher RPMS such as 2500.

TTT

Anyone? if i disconnect the coolant temp sensor plug while the engine is idling it just dies.

you rev the car to 2500 and unplug the coolant sensor, it dies because it goes full rich, (this is why you rev it up). unplugging the coolant sensor prevents the ECU from adjusting the timing, this is all theoretical though, i dont even have my digi 1 wired up yet... do a search in the g60 forum.

Go drive the car for ten mintues

Hook up timing light

Rev engine to 2500 rpm

unplug coolant sensor (blue)

set timing on flywheel

done

i just got my digi 16v setup running, but i set my timing
standard 16v way at idle, so when i did my first initial test
run the other night i was getting pinging.

so i found this, but just to make sure, you gotta get someone to
HOLD the engine at 2250-2500 rpms while you dial in the timing?

thanks

use something to shim the throttle lever, like stacked feeler gauges or a couple of washers. That way you're not dependent on someone else and their ankle precision....

[weejunGL]

if you run digi1, you have to do it as described in the faq in the G60 section

digi 1 is digi 1, no matter what so ignition timing setting is the same

Unless he's running Digi-1 Cali, in which case Digi-1 is dressed up Digi-2. Tell me that's not confusing.

[laychooba]

beautiful!

i had someone hold the throttle while i dialed it in, worked
like a charm. now i just gotta figure out why it's running so
hot!

[Smiff]

Coolant yo!

DaFuq.. then why even call it digi-1? why not call it something else?

i knew there was a digi-1 cali edition, but it never touched my mind while answering

should have called it Digi-goddamnmofo edition 9000

Coolant yo!

yeah, turns out i am retarded. there was still air in the
system, but i still find it runs kinda hot. before i used to
always be below halfway, now it was just hovering a little
bit past halfway.

i only have 17kms on this new setup just cruising around
my house area. i'm gonna pull a highway rip soon, see how
she rolls.
