The problems you are having are burst knock. You have to completely disable burst knock on boosted engines. The pcm does not like the rapid increase of airflow when the maf is failed.

The first tune i paid for is attached. The 2nd is help from 01z28camaro & HUMMER.

You're not getting some form of false knock, it is real. You need to turn the boost down before you blow your **** up and find someone who knows what they are doing to help you out. 17lbs of boost and 15 degrees of timing on pump gas just sounds like a disaster waiting to happen.

I'm just hoping your engine doesn't blow, you need to be more conservative with the tune if you want it to live.
I agree and I know you know what you're doing. When I said he needs to get someone who knows what they are doing to help him I meant someone in person. He is obviously not familiar with HpTuners and it's not something real easy just to jump into and start changing stuff, load the wrong tune and **** goes boom.

The thing is once you change all of your injectors settings to the "correct data" all of your fueling tables will be off, rich or lean based on what settings the tune was dialed in on. So be very careful changing the injectors settings, your tune could go very lean with the correct info. You will need to log your AFR error % against your VE table and dial everything back in. Thats easy to say but if you have no experience doing this with hptuners find someone who can help you out in person. Or turn your boost all the way down and take baby steps dialing your VE tables in.

Another thing to keep in mind, alot of people have been tuning cars with out Greg Banish's recent release of the correct injector info. Yes it may not be the correct info but the correct info has not always been available and people had to tune bigger injectors with what ever worked best for them. It may be not be right but it's the only option some people had.

just updated the tune and with all the right stuff and drove around for a bit id say 75% of the knock is gone now. i think it was b/c i forgot to change the short and default and Min injector pulse data.

now i just have to get my wideband hooked up through the EGR. so i can get rid of most of the knock and adjust the VE

Im aware of that, im still trying to learn the program and yes im new to it. But im determined to figure it out and IDK how else to learn without asking questions

I still need to get it dialed in. My Idle is sketchy and the wideband is reading in the 12-13s at idle so i would like to work on that. Still having issues hooking the wideband up to tuners via EGR Functions.

Under wot i got maybe 1* of knock in various spots and the wideband consistently read below 11.5.

When pulling fuel out of idle should i be pulling timing as well?

Here is a configuration for you to use, you will need to setup some of the Custom PID's to your setup though. It's currently set to a 2 bar map sensor, I cannot change that as I don't have a 3 bar system, but once you connect it to your car you will be able to change it to 3 bar. I have setup some Custom PID's including a boost setup + a boost gauge and logging wideband through EGR. You will need to setup your own Custom PID's though because they do not save when you send the files, I can help you there.

Well crap I can't upload it on tech, I will reply to you on hptuners.

The scanner does not recongize what operating system is in the car until you connect it to the car, it will scan the parameters and find that you are running a 3 bar sd tune. Than you can change the config to scan the 3 bar map that you will find under the PID list.

Does your car have a MAF on it? It doesn't look like your MAF is set to fail and revert to speed density, but maybe the 3 bar sd setup doesn't require a MAF fail code. You're also running long term fuel trims (automatically can adjust WOT fueling) and in closed
loop.

no maf on the car its set to '2 no mil light' under DTC's. i switched the wideband output to pin 55 on the computer instead on 47 still no luck. my function for my wideband in scanner reads~ ([PID.2810]/.5)+10 and ive tried 2811 and ive changed the 10 to 9.8

Do you have this wideband? http://www.aemintakes.com/instructio...-5130_inst.pdf There is info here how to hook it up.

That is the wrong PID also for that wideband. You need to be logging EGR Position (V) as one of your PID's.

Try this setup with the config I posted on hptuners
