about the 1g cam sensor?

[Talon69]

By what this website says, when i make the wiring harness for the 1g cam sensor it does away with my 2 crank sensor correct? so if thAts the case i do not need to put my cranksensor back in when my engine is completed correct?

http://www.roadraceengineering.com/1gcasin2g.htm

Also which method is better?

Method #2 looks easier to do tho lol

Not trying to hijack the thread but anyway; I was reading in the link provided above that when you do the CAS swap you need a data logger to double check timing or to get "base" timing correct. I dont have one, but I am doing a complete 6-bolt swap. Is this going to affect me at all or do I need to just make the wiring harness adjustments? Thanks.

Kevin where are you at????

It does away witht he crank sensor? Well the cam angle sensor is for the timing of the car. Is the crank sensor the same on the 2g?

As for timing. I don't know if it applies to 2g's but seeing if you are doing a complete swap I can't see it being ot terriably different from the way you would time a 1g car.

where as you would set the car to TDC and the cam's to their timing marks, and than time it from there using a timing light.

thats what I had planned on doing from the beggining, then I did some reading in that link and I wanted to make sure. I figured I would be safe doing it the way I had planned but a little reassurance never hurt anyone. Thanks.

There is a plug you have to ground out on the 1g's as well in order to time it so the ecu doesn't keep trying to compensate when you move the CAS

I read the link. The datalogger and what not, I think is more to assist you to find the stock timing easier than normal. I don't see any reason that you have to have that as long as you have an adjustable timing light.

I will post on DSMLINK forum guys to see if we can get some better knowledge on this. Unless Kevin would come around plz lol

I also would like to know the answer to this question.

[Talon69]

Well here is some of the answers i have recieved from dsmlink forum.

1. Yes, the 1g CAS takes care of both the Crank signal, and Cam signal in a 2g car. I, as well as many others have done it this way. You won't have to worry about any misfire problem as DSMlink is here to the rescue.

2. Doesn't really matter. Method 2 is easier IMHO because you don't need the signal inverter since you have DSMLink.

3. If you still have a 2G crank sensor, my preference would be to use only the cam signal from the 1G CAS and retain use of the 2G crank sensor. Ignition and injector timing will be more precise.

Thats it so far

I wish kevin was around to answer some of these damn questions!!!!

DSMLINK forums have a couple of different answers.

[scottsee]

Dsmlink forums are a who diffrent universe of dsmtuning. It's a little over whelming the shit thats on their.

Yeah tell me about it, i have no clue on some of shit i have been reading.

The answers from DSMlink seem accurate. If you can get away with using the 2g crank sensor, use the 1g sensor just for the cam signal and you wont have to worry about RM CELs, DSMlinked or not.

If you keep the crank signal there is no need to set the ignition timing. In fact, it won't be possible. If you use the 1g sensor for both signals the ignition timing becomes adjustable and has to be set with a timing light. In order to get the ECU to hold timing steady, ground the appropriate pin on the 1g, or the brown plug on the firewall near the batter on the 95s. For other 2g I don't believe there is any way to do this, and this is why the "ground diag" feature was added to DSMlink. The only other alternative is to set timing while cranking, since the ECU doesn't alter timing and it stays at 5 degrees. Pull the plugs and hold the throttle open so it cranks faster. Disconnect the injectors and coil pack so it won't start. Or pull the fuel pump relay if you are rewired. Etc.

The mehtod that doesn't require signal inversion is what I used, even before DSMlink. You just have to swap the wires on the coil pack, and if you want, shift all the injectors by one pin at the ECU harness plug. RRE has instructions for this.

If I missed anything or something is not clear, feel free to ask again. It's pretty late.

So if i keep my crank sensor in all good to go? But there are 4 wires on the 1g cam sensor and only 3 on my 2g sensor plug, what do i do with the forth?

Also this is the method you went with? Im lost, so if i do it the way i just said do i have to switch my plug wires around? And what is the point of moving the injector pins over one if you say i can do it if i want!!! That makes me think there is no reason to move them. But im sure you can explain why, like always lol. What ever way you say to go thats the way im going, you seem to know whats best. Thanx alot kevin

Eric

OH also since im most likely keeping my crank sensor i do not do anything from the website? RRE

Use the easy method to wire in the crank signal from the 1g cas into your stock plug for the cam signal. Should be power, ground, and signal. The 4th wire is the crank signal

I didn't personally do this, since I went straight to a 6 bolt, which makes it impossible to keep the 2g crank sensor.

I'm not sure if you will have to swap plug wires using "half" of the 1g sensor. If it wont start, switch the wires on the coils

If it does require switching the plug wires, you could also benefit from moving the injector wires around. The idea is that the 1g sensor is a little bit out of phase from stock, so the wrong injector fires. At wot they are batch fired so there is no effect there. It's more for part throttle driveabilty. Which is why I say you can do it if you want. Many poeple really only care about things working right at WOT.
