Just got DSMLink

[MountainDew]

I have a question and I have searched. I would post on DSMLink forums but I bought the thing used. Just got it today so I haven't even put the chip in yet.

Anyways, when I was reading through, it said something about inverting the CAS. I have a 95' with the stock 7bolt motor BUT I put in a black-top hall effect cam sensor because my stock one was shot after a head rebuild. I did not want to pull the whole head off so I made changed to my ECU and made the wiring harness. Car runs alright except when the CEL pops on every 1.5k miles or so it will stutter and I will have to shut the car off and turn it back on repeatably. If I remember right, it was a baromatic pressure code or something. With link I'm hoping to just override this all together.

I guess my main question here is, will I have to invert the CAS or whatever? Also when I log, would that show the base timing from the CAS?

Also another thing, maybe I haven't looked hard enough but how do I get logs into excel?

Thanks. I'm sure I'll be posting more questions within the next few days here.

Here's the info from the DSMlink page about the CAS inversion.

- What does CAS inversion mean?

For 1G DSMLink, nothing. For the 2G guys, the '95-'96 style Cam Angle Sensor (CAS) sends out a signal that's electrically "inverted" from other DSM cam sensors (1G or '97+ style). When you put a '95 ECU into a car with a non-95 CAS, the ECU ends up swapping the firing order of the injectors. In most cases, this produces very little noticeable difference in drive quality. But we offer the option to invert the CAS signal anyway just in case. You can selectively invert this signal with the DSMLink software as you wish. You will still need to swap your spark wires, though. We can't control spark firing order in the EPROM at crank time. So even with CAS inversion, you still have to swap plug wire 1 with 2 and 3 with 4.

I believe you would need to invert the CAS since you have a non-95 CAS in there. My car is running with a 1G CAS and I have mine inverted. Although I didn't make changes to the ECU - just the wiring harness.

And for putting log data into Excel, read the "For Excel:" section of this tech article on how to post logs correctly (you may need the whole thing in the future too).

Thanks for the help!

I think I may have gotten a counterfeit copy.. it's a V1.

Might be contacting the seller and trying to work something out there.

That sucks. Sorry to hear that. Hopefully it's not fake or you get something worked out.

Honestly it really wouldn't bother me as long as everything works, but I was wanting to upgrade to the V2.

 

[snowborder714]

Ya, V2 is a lot better from what I hear/read.

 

[MountainDew]

Yeah I was going to pay the $50 for V2, but now that it's a fake one I doubt they'd be willing to do the upgrade for me..

I've got the red plug connector.
