ABS module.
 

I was wondering what the difference is between the two different ABS modules.
Does the Delphi have any benefits that made you choose it over the Bosch setup?
I'm assuming there has to be some kind of benefit since you went through the trouble of having custom hubs made with the older style wheel speed sensor.

Thanks for any info you can offer.

Another awesome build, awesome shop, and that is a really cool car gathering...that's my kind of party!

The Bosch production system required communication to a body control module over CAN. Adding the BCM in is a bit tricky. The Delphi system can run more stand alone and had been used stand alone in racing. Newer system are more linked together over CAN. As an example the brake switch and the warning lights are on the CAN bus in a C6 Corvette. So to go from a discreit input (on / off) to a CAN input to the ABS module requires a converter box.

All the newer ABS system have stability, traction, ice and snow modes incorporated. Which means it needs to communicate to the whole car via CAN. Trying to make a OE system stand alone is hard.

Bosch offers a racing stand alone system that is laptop programmable that is great but spendy. That system is very flexible.

I wish you'd volunteer to look at my Lotus 2 Eleven ABS and figure out how to make it NOT go into ICE mode when going backwards (a known bug). :>)

Greg, my degree in theology and biblical studies doesn't quite compare to Mark's engineering degrees, but I think I can help you on this one.

When you start the Lotus, and get ready to roll out on the track, take a careful look at your gear selector. You will see an "R" which is for REVERSE, not RACE.

Sorry man, couldn't resist that one...

Mark, sorry for misdirecting the thread momentarily...

How can he practice his Rockfords without full reverse?

Abs.
 

Thanks for the reply Mark.
I have been following your builds since the Mule, I've loved every one of them.
The latest car is over the top, can't wait to see it finished.
Not trying to hijack your thread but I have a few more questions now.

That's good info about the ABS, I didn't realize that the new Bosch unit required the BCM.
I have a 2010 C6 engine wiring harness for my car. I had originally bought a Delphi Z06 ABS module. The harness i have includes the connector for the Bosch unit so I bought a Bosch module. I was going to run the BCM as well to get the control for the ABS unit.
I'm running 08 hubs and speed sensors so i guess they are compatible only with the Delphi module.

I'd like to run the Delphi unit so that I don't have to buy new hubs. I haven't been able to find the connector for the Delphi unit. The dealer tells me i have to buy an entire harness.
Do you know of a supplier who sells the connector or have a GM part number?


Love the 2 Elevens Greg. My brother has one that he just bought this year. He's loving it but is having trouble with the second gear synchro.
He's looking into either a dog box or a sequential now.

Thanks.

Does he post as BlackPenquinn on LotusTalk??

Wiring Update
 

Speaking of wiring Ryan Kuhlenbeck and I are on our 4th version of wiring. Ryan is the brains behind the wiring and has it sorted out. We are wiring this whole car from scratch. Wire of spools, no kits. Our own fuse boxes and power distubution system.

We will build the engine harness then dyno with its correct harness.

Wow....talk about customization. :idea: Sweet Mark!!
