I don't understand how PW is read/calculated, and thought we were looking for the PW to change. I just wanted to make sure I datalog correctly and wasn't sure if I should have one log while lowering the pressure, or a log after it's already lowered.The pw will not change, the ECU is not referencing fuel pressure in its equation. The only pw change you will notice is that which is modified by ego correction.
@5.0Thunder have you done any testing with map sampling? I was thinking we may want to sweep the map sampling angle and see where the signal has the least mapdot...... right now we are using event average and I feel as though gains could be made here if we always sample from the same angle with the intake valve closed... what I mean here is that if we can find the angle where the signal reaches the ECU for sampling where it is most stable this could possibly help with idle quality.
Great idea! Damn I'm tired, it seems so obvious... Thanks man, I'll do that tomorrow night.Buy a new oil drain pan, drain the oil, then pour it back in the engine with a screen on the end of the spout? I'd be a nightmare if those pieces hurt the engine. Probably worth the 10 bucks to check it.
you have to wait for the engine to be fully warmed up.... cold engines do not like to idle lean.Hey guys, I just ran the car on Rev 2.1.0 and adjusted the fuel pressure to 35psi with the vacuum disconnected. I then tried adjusting the idle VE to get it to run leaner than the I think ~12.5 it was first idling at to see if I could get it leaner.
It seemed to act like last night where it would get to the mid 13 afr rang and then start oscillating pretty badly. I've attached the current version of the tune with my small VE tweaks here as well. Let me know if you see any improvements with the fuel pressure lowered a bit. Thanks!
Ok thanks Steve. What is an acceptable idle AFR? I just didn't want to fowl out another set of plugs so that's why I tried leaning it up.you have to wait for the engine to be fully warmed up.... cold engines do not like to idle lean.
I am going to make a few alterations and we can give it a try.
Haha you know, I've thought about asking you that! I was gonna ask today if you think we could move on towards tuning the car while driving because I have an appt Thursday to have my stifflers stuff and exhaust welded up. They're really close to the shop but would definitely like to feel better about the tune in the "normal driving" range if possibleDo you have WIFI at the shop??? I could remote in and help..... Or we could just let it idle the way it is and you can drive the car to me
Yes we can lets work on the idle one more time, then you can take the car for a drive while datalogging and we can tune the cruise range and a number of other things.Haha you know, I've thought about asking you that!

As long as you have some kind of unlimited data plan, we will use a ton of data in a short period of time.Ok sweet, I was just being paranoidIt definitely was happy rich when warning up.
Oh and yeah I've been tethering to my phone at the shop to upload files while you've been helping me so you could remote in any time that works for you. I'm planning on being there again tonight
