Question on ASR traction control
I'm thinking that for my next project I'll go for a C4 but can't decide on what year.
I'm wanting to know what controls the ASR on 92-up cars as my plan is to replace the LT1 and put in a 415 gen 1 or something along those lines. However, is it possible to keep a fully functioning ASR system while doing this?
Also, has anyone switched from a LT1? Any complications?
Thanks
Robert

Re: Question on ASR traction control (RMK)
There is what is called an EBTCM located behind the drivers seat in the hatch compartment.
Changing an engine shouldn't affect it since it uses sensors placed in various locations.
I have a book on it somewhere, so I can't get specific at this point, but I don't see any reason why a bigger engine wouldn't work as long as you left all teh sensors in place.

Re: Question on ASR traction control (RMK)
The ASR would be controlled from the LT1's ECM/PCM so if you remove the LT1 you would lose the ASR capability. Why remove the LT1? Just beef it up, breathe it up, and bolt a Procharger on it or something if you want crazy power.

Re: Question on ASR traction control (Mr Mojo)
Wouldn't he still need the logic in the ECM for the ASR to work right?

Re: Question on ASR traction control (Mr Mojo)
Thanks for the replies everyone.
Mr Mojo,
When you find that book can you post the name of it and ISBN as I'd be interested in picking it up. Also, where did you get the above pics from? Very helpful indeed.
How much hp cn be obtained from an LT1? It's either a 91 TPI or 92-96 LT1 I'm going to be after. However, the ASR is a nice thing to have :yesnod:
Thanks again
Robert

The pics are from the book, I had scanned them a while ago. Still looking for the book. I actually found it on ebay.

Re: Question on ASR traction control (Mr Mojo)
After we got the 383 motor in my friends car (TreyZ28) It will accually over power the ASR...... Its helps a little bit... But if you hit the gas, they will def spin them :yesnod:
You can make a sick amount of power from any small block 350. The LT1 I feel has the same capabilities as any other Chevy 350. Stroke it out and bolt up a blow and juice

Re: Question on ASR traction control (StealDads67)
OK, I found the book. It's called "Bosch 2U and Bosch 5 Antilock Brake System(ABS) Traction Control System(TCS)
the # is 13003.02-2
There is a phone # for ordering 1-800-393-4831. Don't know if that number is good since the book was published in 1994.
Anyway, I found the part about the PCM.
During traction control operation, the EBTCM supplies information to the PCM. Th ePCM can retard spark timing to reduce torque at the drive wheels. The EBTCM can also control a variety of other torque-reduction functions that vary from model to model.
In addition to spark retard capability, the EBTCM can command the throttle adjuster assembly to partially close the throttle.
The EBTCM monitors engine speed from the tach filter and requests ignition retard to the ECM/PCM(when needed)

Thanks for all the help on this. I'll have to put more thought into my model year. I was aiming for 800hp 406 motor. Many 800hp LT1s out there?

Re: Question on ASR traction control (RMK)
An LT1 will use many of the same parts as any other small block, including the ability to stroke it. The intake design is pretty good and there are some good head options out there. Get some good heads and a radical cam and you can make stupid power, then you just put a blower on it. :cheers:
