Nope it feels fine I just thought it was strange
Turbo ls2 vette 6 speed manual has a lean and rich spot on shifts at wot. Seems like wot fueling has some delay even though i changed the PE ramp in rate to 2.

Ok I'll look into getting a gauge. Car does have a permanent wideband on it. I'll look into FP gauges that will allow me to log it on the scanner as well. Car seems to run great as is though without...
i do have a fuel pressure gauge on the regulator but I cant see while driving. if I turn them on at idle it goes from 58 psi to 60-62 psi at idle. Guess il have to get a electronic gauge that will...
So I installed a new aux pump setup on my 2007 Corvette ls2 and had to pull quite a bit of fuel out when the pumps turn on. So the VE table looks very odd to me now. The 1st pump turns on at 4 psi...
Ok its been awhile but i started messing with the car again. Still have bad kr even though im trying to get around 16ish degrees of timing. I fixed the super rich spot on tip in and i satrted using...
So im still having random kr at wot on 8 psi commanding 13 degrees. Sometimes I get alot of of kr sometimes I get a degree or so on the same timing map. It makes no sense to me at all. Any ideas?

Well did some messing around with the car today. It appears it was either the brake tq table or reverse tq table. Since I maxed them out the throttle opens all the way now consistently now with no...
I scanned for codes and all I get is the maf code (maf delete). Ill try the brake tq and reverse gear tq next. Haven't had much time to play with it lately
Ok well it still does it. The car pulls fine so it seems the throttle body is opening all the way but still shows 38ish percent. What's strange is it doesn't do it all the time its completely random....
All I see is throttle position PIDs. Nothing about ETC. I have throttle position, accelerator pedal position, and commanded throttle position logged at the same time to compare them. I dont see...
i just messed with the virtual tq since i never messed with it and so far its working so we'll see. Ill take it to work tonight and log it again to see if the throttle body is opening all the way...
Ok so I still have the issue apparently. It doesn't seem to do it all the time which is odd. Here's another log

Never mind. Found out it was tq management. Made some adjustments to it and from the short drive i did it fully opens now
Turbo ls2 mt only gets to 38.7% at wot. Accelerator pedal sensor reads 99% like normal. Could this be the tq management? I know it should read like 88% or so.

Someone told me something about under partial throttle the air is slower and since the air in the pipe is slower it heats up faster because of under hood temps. When in boost the air speed goes way...
No cam and the IAT sensor is mounted right before the throttle body
Im thinking this might be the knock sensors being too sensitive and would like to see a second opinion. this is on 93 octane 8 psi on3 7875 turbo stock ls2

Blindsquirrel I made those changes to the IVT terms like you said to and didn't notice any difference in how the car drove or anything so I don't know. and about the cyl airmass maxing out I just...
So even though the error codes are set with the scanner and the car runs with no MAF on the car at all just a IAT sensor break out harness again no MAF on the car at all starts and runs fine on my...
Also when I first put these injectors in I never messed with that IVT parameter and it ran fine. Fuel trims where only slightly off what they where with the stock injectors
So its ok if the timing table doesn't read out past 1.36 when the engine is at 1.46? Because if that is fine then ill just put the tune I had in it before the posted tune. And the codes are set in...
I know I need to scale the injectors more but how would I do that correctly? It has FIC 775 injectors so i already had to half the flow rate and double the stoich to make them work. My spark tables...
Im going to next time I take it out I just wanted someone else input since it doesn't do it on every pull
78mm turbo ls2 stock engine 93 octane only commanding 15 degrees max at wot on just shy of 4 psi and i get around 2 degrees of knock at wot but its not on every pull. Can someone take a look at this?...
