Now with the latest software update (4.something) it seems that HPT has removed commanded AFR and Knock from the p11 ecus. I cannot seem to find a way around using the p11 ecus with tuning anymore.

So a few things to hit on,

1. I've been reading a lot on using Ld9 ECUs on the L61 cars. Has anyone running Ld9s checked recently to see if you can still see Knock and Commanded AFR?
2. I really dont want to have to go stand alone yet (going to wait till next season). So with change has anyone boosted done this ecu change on a Eco?


You drive a cavalier? Why yes... yes I do.

I'm still tuning with 2.24. I refuse to update because it kills options on the jbody ECU's.

I'm also still running 2.24.

Also 2.24.
Which might make it hard for my tuner who likely has the latest version.
