What is the idea behind? You like to fake a speed signal for a limiter?
Once the message is on the bus, there is no way to remove it. It's also not possible to block the message. So what is the...

Because several Users asking via PN about my "Tools" for OBD2 Experiments, here some pics :)

I did use the search function - that's where I saw, that you can use the advantages (?) of a 2002 OS in a 2000 PCM.
The question is: Is it worthy, and which Option mentioned above might be the best?

Hi Thomas,

I just have the hope, the PCM will share it's knowledge about the oil pressure via class2 :)

Hello Forum,

I'm still a bit confused about the "best practice" for a SD-Tune - not the Tune by itself.
I have a 2000 Corvette C5 with Stock LS1, Blackwing Filter, Borla Stinger.
Now it seems,...

Thanks a lot, I will try tomorrow :-)

So I simply download a 2002 stock tune, and upload it (with the help of 2 credits) to my 2000 PCM? Thats all? :confused: :eek:

That's boring! And closes the valce whenever you shift :-)
Currently I can control the valve by speed, rpm & throttle position via OBD2, but this requires some hardware (Arduino). At least for MN6...

Hello Forum,

I'm wondering if it's possible to use the Shift Light Output on an LS1 PCM for controlling the valves of a dual mode exhaust (like B&B Fusion)?
Change the Shift Light Setting to...

Not that new here, I came in because I was looking for informations about Class2 PIDs on J1850 Bus.
Now I will be more here, because I bought a VCM Pro a few days ago, plus a Wideband O2. What a...

Any idea in what messages this infos are?

While driving, IPC sends:

A8 73 60 08 XX YY
A8 DF 60 12 XX
AA EB 60 20 XX YY
CB EB 60 20 XX

The last one is more or less...

So I just download a 2002 stock tune, and do a full write on my PCM? What's about this possible VIN mismatch, do I have to / can I change the VIN afterwards to my original one, or will the old one...

Hello Forum,

new in this Topic, so pls. excuse if the question is stupid :-)
Where do I get such a new OS? Copy from a friends Vette, or is there a place to download?

-Michael-

The C5 cluster gets the information directly, not via Class2...

AFAIK Fuel Level and Oil pressure is NOT on Class2" it goes direktly wired to the IPC. Take a look at the C5 IPC Pinout, there you will find the right Pins :-)

Long time ago...
Since a few days I'm back playing with my C5 OBD2 Stuff.
Target is a kind of Valet ( :cool: ) with an ELM and an Arduino for my Vette. Works so far, I can open and close my Window...

No Problem, I will check again this weekend :)

sorry for the long delay, I had some troubles at work, and I didn't see my red lady for a couple of days.
Finally it's done :-)
