I have a 1970 Chevy Impala, with a 6.0l LQ9, with DBW, totally stock except for a Magnacharger and headers; trans is a 4L80E, both controlled by the same re-programmed PCM. Rear end is the bone stock original 12 bolt. Engine, harness and computer are from a 2005 Silverado SS, modified by Speartech.
Is there a way to "add" a traction control system to that set-up? Maybe something taken from a modern Chevy, or aftermarket? Something cheap and simple (yeah, go ahead, laugh!!!) would be best, as I certainly do not intend to change my whole set-up, but who knows, maybe there is a way?...

Not really. Factory stability control is very complex, its integrated into the Anti-Lock Brakes along with the wheel speed sensors, so lots and lots of work and effort to have a traction control that is as good as came on a 2005 Chevy work truck... The best traction control I can recommend is a fresh sticky set of tires.
I have a '93 RX-7 and had Bob Ette add a custom front wheel speed sensor setup. My Holley EFI takes the signal from the front wheel and also a speed signal from the driveshaft and if the normal acceleration rate differs it will pull timing. I'm very happy with his work and it was very reasonable.
Hello, Mark;
I make kits to find driveshaft speed and front or rear wheel speed so that the ECU can act on non-parity of the two speed inputs. My driveshaft kit clamps on the slip yoke, and my wheel kits are generally 22-tooth reluctors and one sensor installed on the rotor or hub and caliper bracket in my shop. Customers send the hubs and caliper brackets to me for this work, and the slip yoke kits are customer-installed.
Are you looking to do both?
Attached are some photos for reference, If there's a good time to call this weekend I can do that, or I can be reached at 314.435.3461

Many thanks,

Interesting photo, seeing one set-up done! I am in France, so I will not be sending my hubs to him. Anyway, I cannot find this Bob Ette online, will I find him under his shop name, or something? Maybe he has knowledge about parts to use (and sells them too!).

Shows him installing a front wheel speed sensor the cheapest way possible. You just get a factory sensor and get it as close as you can to the back sides of the studs and it reads off of those. You just change the frequency of the sensor pickup in the tune to accommodate the number of "teeth" you're using in what ever tone wheel you use. Be it the hub itself, or some spacer setup like the one posted in this thread. You could give that picture and your hub to any competent machinist who touches cars and they should be able to recreate that in house with very little effort. I trust France has at least one motorhead machine shop guy. I know Germany has some hotrod type shops that make stuff like that.
There are a lot of ways to add a speed sensor to an old front hub honestly.

Robert Ette traction control maybe easier to find him. Here is his email
http://www.racetcs.com/ this is also an option for you once you get a signal going on front and back speeds. Completely independent of the factory ecu.

Yes, there is most likely a machine shop near me that could do something like that, the point is to find what is possible, what works (or does not!) beforehand. And then what sensor to use, OEM is always best, more reliable than aftermarket, and easier to fins down the road. I have looked into this RaceTCS you give the link for, I will probably use it, my last thing to solve is the front wheel speed, with a passive sensor.
