What's the setup? Engine size, injectors, etc.? It's obviously forced induction, but what? What's the fuel system setup? Return? Reg after the rails? Fuel pressure?
At the end of the log the...
It definitely has something going on with bank 1. Need to do some diag work. It's not "in the tune". First thing to do to narrow it down is check the header tube temps with a temp gun. Look for a...
Need to check your fuel pressure also. Check fuel pressure, pull a couple plugs see what they look like.
That's part of the problem right there. Low pulse width control. It's overly rich for a few seconds when the throttle closes.
I'm impressed with how tight the trims are though for the most part.
What injectors are in it?
I'd bet those numbers get him a lot closer to reality KOEO.
I don't think anyone thinks you're trolling.
Need to know exactly what injectors you have if that means pulling one out and getting the PN off it. It all starts with correct injector data.
...
In your OP you stated "TBSS intake and stock injectors". What are the injectors stock to? A TBSS? Did you pull a TBSS file and swap over the injector data? "Stock injectors" is not a one size fits...
I think you're seeing noise on the WB input. A miss will almost always be reflected in the narrowband sensors.
You have the injector data sheet from DW? Need to post that. And what did the MAP sensor come out of, or do you have the linear and offset?
If you have to crack the throttle for it to start that means there's too much fuel.
I haven't looked at anything. Have you dialed in the VE and MAF tables?
Is the injector data correct?
OK, well need to figure out why it won't start. Have you tried cranking in clear flood mode? Pedal on the floor? It has to be one of three things. Too much fuel, not enough fuel, or no spark. If it...
LOL MMMk
The OE file I have says your adaptives are all modified.
As for the dip after the throttle blip, just add a bit to your BRAF. Your BRAF is 11.1 g/sec @ idle but you're idling between 11-12.8...
The VE table is interesting that's for sure.
MAF curve isn't the best either.
Data log will tell you more than the tune file will. A tune file can't tell you what's going on.
You have an overactive throttle blade and under active timing control. You need to pull a stock file off the repository and put a bunch of stuff you've changed back to stock.
ALL of the idle...
Throttle body/PCM/pedal have to match.
Edit: wrong section BTW.
Data log and tune. Feel like a broken record. This is me right now ---> :banghead:
Why did you back the throttle blade all the way off if it took that to get it to idle? Why would you not data log it as is with the attached channel config?
Did you try starting it up while...
You have an O2 sensor code. Might be why it won't go into closed loop.
I don't have an answer for your misfire counters. do you know how to add a channel? They won't automatically show up in your...
Is +5 the average or the peak? Does it bounce over +10? Just saying "+5" doesn't really explain how the vehicle is running. As far as I've seen you haven't posted any data logs, before or after, so...
Bottom line is, your PCM doesn't care what your wideband says. Forget about wideband tuning part throttle. Forget everything you've read. Unplug your wideband until you're done part throttle tuning...
I took a quick look and couldn't find a data sheet on their site. Why are you using such a big injector? Plan on supercharging or turbo charging? If not, they're way too big. You'd have much better...
Post the data sheet.
