Can you modify the Whipple Tune?

Did you poll the pcm for supported parameters?

Several times. Also cycled power on the car and restarted the computer... same result.

So I tried it in a different car and was able to log those parameters, so I dont think it's an HPT or computer issue:

BELOW is not from the car in question but shows those parameters being logged

You’re looking for lambda or eq ratio from sensor 1’s.

Thanks, found those, here is a snapshot and I'm attaching the log file:

@Rolls for anyone interested this post shows what a cat test looks like in the o2 sensor signals. I’ve found it usually does this within the first 5 minutes of driving once the engine is warmed up and you run steady speed.

You have to log o2's and capture a test cycle.

Gents, any thoughts on the log/screenshot above? I read through the Roush cat failure thread, but I'm not experienced enough to know what my log is saying. Any help greatly appreciated. Let me know if there's more info needed.

Thanks

@Tim the data seems to imply failed cats but you’ll need to catch a cat test on the log for anything more conclusive.
