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