I have a ZZ502 installed in a first gen with a Holley Commander MPFI 950. I got it running for about a month ago, but, tuning it is a chore. Not to say that I got into this thinking it was going to be plug and play, but, it is a little more than I expected.

So, If I can get the honor of posting the first official question...

What's the recommendation for a wide band O2 upgrade?

Holley's 534-197 Wide band Oxygen Sensor Upgrade For Commander 950 w/ Bosch LSU4 sensor

Jamie I feel your pain! We gave up and took our vehicle to a F.I. tuner in Troy Michigan and rented some dyno time. It took 15 hours to set up the vehicle with the Commander 950, Ouch! I asked about the wide band sensor myself and he said there was no benefit since we already had it on the dyno. Guys setting theirs up in the field however say it helps them tremendously. Our problem was the O2 sensor supplied by Holley in the kit was no good right out of the box. Once it was replaced the set up went smoothly. But again the tuner did it. The dyno time and tuner bill easily came to 5 times what the Holley kit cost. But the vehicle runs great now. I've also been told by one tuner that they don't suggest or sell the Commander system due to all the problems they've had with customers bringing them back with failures. We also have had one controller fail within the first few months after installation. Probably not what you wanted to hear, but I know most guys installing these systems seem to love them. Holley's tech line wasn't much help either unfortunately. I expected much more from Holley than we got.

I've tuned one from scratch, a TBI 4DI narrowband, on a medium performance truck motor. Between the narrowband and the fact that that system won't update the ecu while running, it was a bit of a hassle, but I did eventually get it to run pretty good.

The only failures I had were the Bosch fuel pumps they used to supply. Third time, I said the heck with it and put a holley red pump on it, end of problem.

I'm looking forward to tuning my new system, with save on the fly and wideband.

The wide band is the only way to go , and for larger camshafts allmost a must . I still play with ours at cruise a bit to see how lean you can get it for economy . 15 hours my god what was he doing , Jim it only took sandra a trip to billings . I can't wait to start tuning our motor with the blower on it .

Mark that's what I thought to 15 hours? Then I found he had to pull two 4 foot by 6 foot by 3 inch thick steel plates off the back of the vehicle because there was more weight over the rear axle than the dyno was rated for (vehicle weighed between 10,000 and 12,000 pounds). I'm sure that took several hours and the fact that the narrow badn sensor wasn't any good as supplied by Holley wasted some additional time that we had his dyno tied up. Since there isn't a fuel schedule for this application it may have taken a little longer to set it up than had it been one of the maps already programmed into Holley's software. Toss in that it was billed to our corporate account and that may account for some as well. In the end I know I tied up their dyno for more than a few nights, I'm just glad it wasn't coming out of my pocket!

Got my LC1 today. Can't wait to get it working. Hopefully it will take care of some of my tuning problems.

Question - The LC1 install manual makes reference to fabricating a heat shield out of copper to act as a heat sink.

Since we all know Camaros, I have long tube Jet Hot coated headers with the O2 bung installed where all four pipes merge. Should I be worried about heat? Can anyone comment as far as me using a Bosch sensor without a heat sink in this application?

Obviously, I don't want to end up with a sensor going bad prematurely.

You should be ok there , mine are about 10 inches down the main tubes of the exhaust system . I use the wide band setup and it works great .
