2G 1g cas / timing question

[Wobble]

Im doing a 6 bolt swap, so im using a 1g cas (1g everything actually)

so..

1: do i need to set my timing by turning the cas now?

2: what should i set the timing to (what is stock timing at idle?

3: what problems should i expect?


im doing it the magnus motorsports route where you rewire the CAS to do cam and crank timing, seems pretty simple..

Once you get the car running, even roughly at best you set base timing with a timing light and rotating the CAS. Just get it in the ballpark to start if you don't know where it should be.

2: what should i set the timing to (what is stock timing at idle?

Base timing is 5 degrees BTDC, I would start there.

3: what problems should i expect?

Nothing really, as long as you do it correctly. One thing I should have mentioned above is that you need to set base timing by grounding the ECU so that it stops adjusting it and believes it's at 5 degrees. If you are a 95 car you can ground the brown mystery plug on the firewall for this, otherwise you need DSMLink v2 or perhaps some other method that I am unaware of.

Yep, it's not all that bad. More time consuming than anything.

There is a pin that you have to ground out before you actually adjust the timing. With the pin ground out, you adjust the timing to 5BTDC and then once you've done that, and unground the wire, you'll see 8-9 BTDC.

 

[Wobble]

great, but i really need to know what wire it is I ground.. any ideas folks?

 

[Wobble]

With the pin ground out, you adjust the timing to 5BTDC and then once you've done that, and unground the wire, you'll see 8-9 BTDC.

well.. if in proper timing it reads 8-9 BTD ungrounded.. why not just leave it ungrounded and set it to that?? i mean.. if you know 5btc grounded = 8-9 btc ungrounded.. why would you need to ground it?

 

[DevilSperm]

because by grounding it you basically bypass the isc....you dont want the ecu recompensating as you are adjusting

 

[Wobble]

i see, and i cant just disconnect the ISC? man.. i never have used a logger, i have a wideband o2 that a tune with and i REALLY dont want to buy a logger just to set my damn timing 1 time..

 

[DevilSperm]

actually you arent supposed to have the logger plugged in when you set timing because logger bases its reading off of the ecu thinking its a 5 btdc so it would be wrong if your base timing was wrong

this is off a 1g, i dunno if 2gs have this plug or not but this is what you ground http://members.shaw.ca/dsm.1000q/Engineprimer/timingconn.htm

anyone know the wire colors for this mystery plug?

 

[Wobble]

ok.. goddammit.. something here is making sense..

what im getting is that i have to buy a stupid datalogger to set my timing.. BUT i cant use a datalogger to set my timing because it wont set right using a data logger..


that makes absolutly no sense.

 

[DevilSperm]

sure it makes sense....to set your timing you need a timing light, not a logger

this is the problem, i do not know how to groun a 97 ECU and I DO NOT want to have to spend over $300 on a device ill never use except to set my timing one tim with..

THAT is the problem...

 

[SpoolnTsi]

ive set my timing a number of times and i never once grounded that wire(well i did the first couple of times if set my timing) but either way i never noticed a difference between the times that i did ground it or not. never had a problem either way

Listen bro, get the "need to buy expensive gadgetry(sp?) just to set my timing..." thought out of your head. It's absurd. If you read that link which im sure you did, what you need to do is find that "engine timing adjuster" in the 2g. That will ground the ECU from seeing timing. Get the light out and set the base timing. As you read in the article 2g's have a non adjustable CAS. Hopefully your using the 90 or so CAS. So you dont have to worry about that problem. Adjust the CAS like stated in the article. Unground the "engine timing adjuster" and then. No more and then.

this will be the last time i post on here because you are getting pissy with me... GO BUY A ####ING MANUAL

 

[Mike 99GSX]

A timing light costs $25. Thats all you need.

i cannot find the engine timing adjuster, it does not seem to be in 2gs.. maby because you cant adjust the timing..

i dont know the colors for it, and the picture of the plug is vague..

sure if i had a 1g with a motor in it i could prolly go by the pic.. but i have a 2g with no engine in it.. so its VERY VERY VERY hard to find it.. if indeed it is there.

so, just go down to autozone and buy the haynes 1G block in 2g swap manual eh?

well if you cant figure it out maybe you shouldnt being doing the swap... anyway, ive done as much as i can for you..good luck with it
**edit** the link is for 90-94 and starts with 2.

Ive done everything fine so far, including rebuilt the tranny, i know what im doing..

this is the first and probably only thing ill get stumped a little on.

where does one aquire the said scan tool from the description listed..

also.. it says 96-97.. but i though the 95-96 and then 97-99 were different ECUs.. ????

 

[Wobble]

here are some pics of the harness i did, just for the hell of it..

well a logger would help just bustin your balls....my chilton shows the 95 being almost exactly the same as the 1g, as far as timing it anyway... i guess wait til a 2g guy comes in here cuz to be honest, i dont think ive ever seen the bay of a 97-99 turbo

Wobble, I didn't even see that you had a 97 car, sorry. You don't have the brown plug on the firewall to ground timing so you need to use dsmlink v2 and timing light to set base timing correctly. See if you can borrow a "DSMlinked" ECU quick in order to do this, otherwise I don't know of another way to do this. I suppose you could start the car, let it warm up fully, then adjust the CAS until your rpm's are 750. Too much advance and the car will surge, too little and it will stumble.

ohhhhh ok, so now insted of just needing apocket logger, i need a ####ing standalone computer system just to set my timing???


this just gets more redicilous the further it goes...

 

[Wobble]

im not buying DSmlink to set my timing, and I have never met a single person using it.. so i cant borrow their ECU...
