I have a 2000 C5 that i was trying to do some RTT on today. I ensured Real time mode was set to VE but no changes I make effect anything. I ensured I was running off the RAM table. I went to 0 in the idle VE cells as a sanity check as well as surrounding in case it was averaging them and it did nothing. Ditto up into the 80s. AFR just stayed where it was. I had attempted this w/ the MAF failed and without. Fuel trims disabled as well as with it forced into open loop and without. Looking for any input you guys may have as I'm a bit stumped here. Everything I have seen about this indicates I've done what I need to do to run RTT.
Thanks much guys
Dave
