Yes my AFR is right around 11.3 when the W/M is injecting at 7 psi but wanting to get more timing advanced in that boost range. What's the lowest you would take the AFR 11.0? or should I just call it...

When I was running 100% water injection I knew when I hit the limits cause the engine would start to bog and then I would back off on the controller a bit and all was good.
Now I'm running about...

That worked, O2 readiness ECT enabled STFT thank you for the help!

Ok thank you and yes I wasnt sure if I was missing something but I will enable the O2 readiness ECT, I thought there was a stft table somewhere, in the tune on the other thread I was running maf only...

How are you enabling closed loop? I dont have a tab for that either just ltft ECT and O2 readiness ECT table

I only have the option to enable and disable LTFT in my tune but nothing for enable STFT only. Maf only tune running in open loop but would like to enable STFT closed loop with the maf tune. E38 ecm...

P0121 and P1101 both popped up, after I cleared the Code and it still would not engage PE, then later on the code came back so that's why I maxed the values out in the tables. That was about 3 weeks...

Yes I will try that thank you

The reason for the tables being maxed I was getting a cel for the p0121 and heard that was the fix but I had the PE problem before I changed those values though. And I just dont want to change the OS...

I have attatched 2 log runs and the tune for those runs, both have the same tune for the logs. First run PE commands good and then I shut the vehicle off a couple of times then I take truck the next...

Tonight I will try to post tune and log

After work I started truck drove to the gas station and truck would enter PE right at 1 psi maybe a little less like it should and all was good. So this makes 3 previous key cycles. I turned off...

I redid alot of pe parameters in the tune with the PE going partially off of tps and kpa instead of just kpa, partly because my baro would rise as I would get into boost thinking this was a problem....

The new PE changes worked for 3 key cycles, now it wont go command PE again. This is the same thing that has been happening. I dont have any CEL's but I checked anyway and I have code P1101 pending...

Also I already have zr1 map sensor installed

I changed kpa enable to 104 kpa and set the hot throttle table to 10% across. PE comes in around 0-1 psi which is good I guess. I will drive it to make sure it stays this way. But still not sure why...

I had it lower at 104 kpa but it would go into PE on hills under load when I hit 0-1psi of boost, so it was constantly in and out of PE, but that is better than it not going into PE at all. I guess...

Hopefully the images aren't blurry but one pic is of it commanding pe the other is under the same circumstances just a few hours later with the same tune and it not commanding pe. And one pic is of...

I dont see where I can post pics from a phone

Has anyone ever had a problem with PE engage sometimes and then on the next log it wont? Same conditions just a few hours later.

E38 2012 Silverado turbo 5.3

I have Hot TPS table set to 5%...

Yea injectors are coming soon, and plugs already done. I might end up doing the VVE on down the road I just dont have a dyno so I feel it would be hard to get the table dialed in correctly right now.

Just seeing if I have this all down before I head into tuning my truck. Truck is a 2012 e38 Silverado stock 5.3 adding a turbo low boost at first 3psi then up from there. My plans are to be MAF only...
