I'm just curious to see if with the swap we would also gain the bonus of getting into comp mode easier.

Great write up. Thanks for your time and effort in sorting out this problem.

On a C5 without AH would the swap be the same except for not having to deal with the steering wheel position sensor?

Thanks

I haven't studied the schematic for a C5 without Active Handling. However, I don't think the late model C5 EBCM will function correctly without inputs from all the sensors associated with AH (SWPS, all yaw sensors, etc.). I think the conversion from non-AH to AH could be accomplished - but all the appropriate sensors and wiring would need to be part of the work.

I would agree. The sensors would have to be added. There are a couple of extra wires on the SWPS that could be used to wire these sensors.

The early C5's without AH still have a SWPS.

I confirmed this morning that Competition Mode now activates while moving at over 5 MPH (I tried it at 30 just to be sure).

That's freaking cool.

As owner of a 99 coupe, I BLESS your carnivorous Soul.....

Gonna start collecting PARTS "NOW"..... LOL

I just did a copy and paste of your entire procedure to a local file on my pc. I hope you don't mind. I've already started a conversation with one of my best parts sources. I've explained to him what I'm 'up to'... LOL He wished me luck.

The rear-mount ABS is the best part of 97-98 cars. Why move it to the front? Much cleaner engine bay and better weight dist. Would have to retro the bracket a bit but I'm sure you could make it work of you're capable of the other parts of the task.

Hi: I am one of the fortunate ones that have a 99 c5 coupe with a distroyed ebcm, code "V". You mentioned that due to your work on your buggie, you would have 2 used ebcm's that you would consider selling to defray the cost of parts for your conversion. If so, I would be interested in buying on if it is not too expensive. Your reply would be appreciated. Not being cheap, but the same reason I have not bought one from a recycler is I would have no idea how long one used would last. Somehow have more faith in one that is being changed and not from a wreck. Thanx, Vince

Very good write-up. Thanks for posting this.

Great job brutha.

Great Job!

I see you did not use the YAW sensor nor the ladderal sensor. I did not read the entire thread and this may have been asked: Your not getting any ABS codes for those sensors?

We will start offering these kits to the public as we have it all in stock.

Thanks,
Marc

The early C5s with active handling already have the yaw and lateral sensors.

Retrofitting the late model ebcm into an early C5 without active handling would require the addition of those sensors. I'm sure it could be done but definitely more work would be involved.

Marc@Vettenuts.net

Thats right. Im very interested in doing this conversion in house for customers.

I'm the happy owner of a functional 98 (non AH) with a "properly functioning" ebcm.
The though of not having a fix is daunting if it does go, I'm kinda screwed. having the AH sensors "faked" could be an option? I have a fairly decent knowledge of serial communications and I'm a system administrator so perhaps we could just figure out what feedback the ebcm wants?


Thanks for investing the time into this man!

Caddy2006

I misunderstood your question.

I have no codes after my conversion.

I think this is a worthwhile service and will benefit many.

If we can trick the 98 shocks we can trick anything right? Im running c6Z shocks and did the f45 bypass. Love it.

wvufan1965

curious, why did the ABS get moved to the front? I have been contemplating this exact thing as well but want to keep it in the back if possible?

I wonder how hard it would be to get someone like www.eficonnection.com to make the wiring harness adapters so no cutting or splicing of the factory harness was necessary?
