k I just did that to the VE - It looks smoother compared to before. I did smooth selection twice. How does it look ?
I will get some more logs tomorrow.

I have been working on it just by driving and adjusting based of the AFR Error. I haven't really done any WOT pulls yet, since the tune I originally got had the VE set high enough that was blowing...

I have attached a log from Saturday, first part of the log everything looks fine. No KR or very little. Truck drove really good. Then on the last start up, it starts showing 8* KR. No error codes or...

I had a similar issue with my build - very similar to yours. 00 Silverado, LQ4 370cu, gt45 @ 5psi (will turn up to 10psi today most likely lol), tsp 216/220 .600 cam. I was noticing random KR and it...

LQ4 bored to 370

So I have been tuning my 00 silverado, LQ4, 80lb injectors, gt45 turbo. I have it drivable, but it picks up knock randomly. Sometimes it runs great, and sometimes it shows 8 KR. Doesn't matter if its...

Been awhile but I got a somewhat drive-able tune. Only a few problems - my new AC Delco knock sensors are throwing codes, above 3000 rpms it doesn't want to go anymore, sounds like its misfiring,...

alright - so ignore the previous posts. I think the injectors were ultimately the issue, lack of data that I had for them.

So now I have 80lb deka injectors (with known data), running at 58psi....

Did some logging. It started fine on its own today. I logged idle (VE was running lean originally), then adjusted VE so it idle'd smoother, then when give it throttle it leans out, so more work to VE...

Sorry for the delay in responding. Attached are the tune files - the 2 bar tune , and stock 1 bar tune. I will get a log when I get back home, hopefully tomorrow.
I made sure the MAF DTCs were set...

I picked up a new ACDelco 2bar map sensor. Adjust the map scaling for it and now reads 100kpa key on engine off.
It idles for about 10 to 20 seconds then shuts off. Idling its roughly 30-35kpa. ...

I messed with it some today during this snow storm. I adjusted the MAP sensor settings some, with no good results. It kept reading 105kpa ignition on, engine off. So I decided to revert to stock,...

got it. I must have changed it in the other tune and not this one. I adjusted it and added 2g/s as recommended. I will put the tune on the truck and log it tomorrow, see how the results are.

Made the changes. Everything else look fine for a base besides that?

I set the MAF dtc's and raise the rpm disable to 8,000rpms. I plan on keeping it in SD.
The injectors was a typo - they are 42lb at 43.5psi. I have them running at the stock pressure of 58psi,...

sounds good. I will adjust some and see what it reads with ignition on, engine off. I found a thread that gave a couple different linear and offset numbers to try with that part number. I will make...

The tune did have it set for 200/10.33. Sloppy mechanics wiki says 207.66/9.00 for 2 bar MAP.

Thank you. I found that same link after some searching and was able to get it to idle and shift into gear without dying. I did find the airflow was all messed up. I checked it against a stock 6.0...

did another log, adjusted injectors back to factory settings (still 42lb injectors), and adjusted VE table. I highlighted the VE table and multiplied by .70, seems to idle good. Still dies as soon...

Having small problems trying to tune the following - LQ4, 42lb injectors @ 58psi, gt45 turbo, wastegate set to 12psi, 2 bar MAP sensor. I plan on putting 80lb injectors at some point. Still learning...

I must not be doing something correctly, they are listed under the channels but no values are being read from the ecu.

Just updated VCM to 3.0 and now my scanner won't read the MAP sensor, O2 sensors, or MAF sensor from my truck (2000 chevy silverado). When I use the old 2.24 version of VCM, it reads everything with...
