Re: Opel Commodore GS/E 3,0 24V
Trackday yesterday went well, around 80 laps i think. The track is rather short, only 2072 m.
A little movie, chasing an Opel Astra GSI. Maybe its called Vauxhall in UK?
And yes, engine still runs with stock ECU
I will give the DTA a new try soon, but i also want to drive the car as much as possible and want it to be 100% reliable enginewise.
Also replaced the starter motor, the solenoid was damaged on the old one.
Got some new grease into the replacement starter and now enginge cranks much better.
Also when engine was really warm yesterday it worked perfectly, so that should be sorted now.

Its a Nokia N8 "smartphone"
It can take video in 720p, so try changing quality in Youtube player. Standard setting is 360p for some reason.
Bad sound though, microphone is not the best. But its a decent camera and its strapped to an old GPS-mount with zip-ties
Sort of "anti-Gopro"

Re: Opel Commodore GS/E 3,0 24V
Checked the timing advance with stock ECU yesterday.
I have checked it a while ago but then the Hall-sensor in the dizzy was broken or something.
Anyway, back then the timing was flying all over, probably because stock ECU uses the Hall-sensor to sync ignition when the knock function alters the advance.
Now with the Hall-sensor working the advance is steady at 6-8 degrees BTDC in idle, if my markings are right.
It rises to about 20 degrees at about 2500-3000 rpm.
My timing light is the cheap model that only flashes, it has no dial to set advance.
Found a used digital timing light on ebay for about 92$, if everything goes well i should have it in a week or so.
Then i should be able to read the advance more accurately, both with stock ECU and DTA.

ermm... if your marks aren't accurate, then no matter what you set the dial to you'll be guessingAnders_Karlsson wrote:Then i should be able to read the advance more accurately, both with stock ECU and DTA.

Re: Opel Commodore GS/E 3,0 24V
Guess i will find out soon
I measured the TDC with a caliper a while ago, but i think i will do it again with a dial indicator to be absolutely sure where TDC is and make new markings if necessary.

Re: Opel Commodore GS/E 3,0 24V
I measure piston height coming from either direction, then half way between is TDC. Easier than trying to get the rocking point.
Often the crank pulley keyway is at an ideal location such as TDC which makes it easy also.

Re: Opel Commodore GS/E 3,0 24V
I'd expect an older engine like that to already have a TDC pointer

Re: Opel Commodore GS/E 3,0 24V
There is a TDC mark on the flywheel with a pointer in the block, but i have a custom made steel flywheel and it does not have the mark.
Tried to make my own marks on it but im not sure if i got it right.
Its easier to have markings on the crankpulley, better visibility from the side.
Flywheel markings are a bit obscured by exhaust manifold.
But i will try the halfway method, that should work just fine
This engine was originally fitted in Vauxhall Carlton GSi and Senator in the UK.
Came on the market in late 1989 and ended production in 1993.
It is closely related to the CIH-engine, shares the same cyl. spacing, bearing diameters etc.
The CIH was designed in the mid 60ies, so its quite old

Re: Opel Commodore GS/E 3,0 24V
Turns out my handmade TDC marks was more or less dead on
Cameraflash right on the TDC-mark but i hope you get the picture .
Next step is to check the timing with a proper timing light, install the DTA again and then hopefully i will get it running a bit better.
Nothing wrong with the way the engine runs now, but i know there is more power and driveability in there.
