I've been able to make some progress. I got a 3g MAF, and some 560 injectors. Still getting knock on a severely retarded timing map. At this point, I suspect a faulty knock sensor. The goo hasn't melted out, but it does seem really squishy. I also found a small boost leak from my throttle...
I knew this time was coming near, just didn't know what to look for. I do have the stock MAF currently installed. I have a 399 MAF on the way, just trying to source an adapter. Because of California smog, I like the option of being able to switch to the stock set up for that one day.I'm...
Ive developed a stutter at around 11 psi. I suspect a BL or plugs out of gap. Log posted for comment. This was notices when attempting a 15psi knock check. I'll do a BLT and new plugs tomorrow. It's not severe, just less ... go. Injector duty cycle peaks at 80, fuel flow at 80l/hr, well...
I'm making progress, but still getting one count here and there. I'm noticing a difference between AFTEst and LC1WB that wasn't there before, although it is about 20 degrees cooler today than before. At what point does rich knock become a factor? LC1WB got to 10.4. I don't THINK this is my...
I think I got my 200 and 400hz figured out.
My next question is about WOT. My load factor is only 1.4, but I'm still getting knock. I've attached two logs for this, the first is the only true WOT, but shows some deviation between AFR Est and LC1WB. I fixed this on the second pull, but I...
I'm kinda a one man band over here, so I have to review logs after the fact. I think my 100-200hz needs some work, but 300-450 seems solid. I need to widen my OL thresholds a little bit more to get higher hz numbers, but here's what I got so far.After this log, I went up 8% at 100hz and 1%...
Sounds like a plan. I'll try and get a cruise log tomorrow. I saw a video suggesting I can use wbfactor as a quick guideline for how much to raise mafcomp, I'll verify this tomorrow. I also saw how to change CL requirements, so some of us noobs really do watch the videos!Since your spending my...
I think I went the wrong way with MAFComp, and I hate to blindly trust the MAFComp Adj....Hypothetically, if I raise the MAFComp at say 500hz 10%, then the ECU "sees" 10% more air and adds fuel to compensate? So adjusting MAFComp in a positive (or less negative) direction makes things richer...
This is awesome help, thank you. So it sounds like I have the following things on my list:
Adjust MAFComp at related freqs so real and estimated AFR's match.
Upload 2G timing map (I thought I did this, but I'll double check)
Double check MAF at 1300hzTo answer your questions,I'm in CA so...
I did a 3rd gear pull. It's in the mid 90s, and not quite 10 pounds of boost. I'm using a 2g timing map, but still getting a little knock with conservative boost. I'm interested in your feedback.
Here's my cruise log. My STFT and LTFT Lo and Mid seem to be where they are supposed to be, so I'm happy with that. If you see something I don't, please let me know. Later tonight or tomorrow I may try and get some WOT pulls in 3rd from 3k-redline. My plan is to start targeting 10psi with...
Rand, I understand what you are saying, and I appreciate your comments. You are probably right, but my build will be slow, and tuning is totally new to me. I look forward to learning.Lumpy, I appreciate the concern. Im just not as advanced as you thought!
I typically cruise at 10psi, but occasionally 15. Randman was correct, BLT was good to 20, but I don't see those numbers.I have my eyes on some 550s, but before they go in I'd love someone to give me feedback without too many variables, more so for my learning. Once I get a relative...
I fully intend to, but while I'm learning Link, I'd like a critique of this idle log, then I'll get a cruise log, then WOT.Then I'll know what I'm aiming for and a bit about how to get there when dialing in the larger injectors. This helps me separate potential issues.
I've lurked around this sight for a while, and have asked some smart and some no-so smart questions. I finally got things sorted with ECMLink and my LC2, so I'm ready to start setting baselines and then tune! Below is the idle log after a drive, please let me know what you think. But First...
I'm a noob with my stuff all messed up. I read the recommended prereq thread, it would help us noobs if that list was visible here so we don't forget anything.
The car is mostly stock GVR4. I'm running stock injectors and FP, with mods being a 16g, FP mani, 2.5" exhaust, K&N, and a LC2 WBO2...
I got another Walbro fuel pump (this one I didn't spike on the ground), upgraded the wiring with 10 gauge and a relay, and remounted the ground. Things seem to be flawless right now, but I don't know which of the three was the culprit. I want to reinforce the ground in the future for...
While I was finishing up my wiring this morning, I did find that the ground was loose. No doubt, this is part of my issue if not all of it. The ground is on the rear wall of the trunk close to the trunk latch. It's always the simple things...
FINALLY got my Walbro pump and kit, so I pulled my old unit out. At first look, everything looks to be okay; the sock was a little dirty, the bottom of the tank looked clean, the steel fuel line didn't seem to have any cracks in it, and the tub looks to be in place. So at this point it's...
I am NOT logging. I've looked around, and it looks to be unavailable right now?This issue on a stock car is fairly significant.... I wouldn't imagine it will be hard to diagnose. Maybe I'm being optimistic.I think your first post is going to be close to the mark. Crap in the tank...
I installed a new stock FPR, which did nothing to address the problem. Not a surprise, but wanted to rule it out.I did get the problem to repeat on a flat corner at a left turn light. Flat approach, 5ish pounds, downshifted for a quicker left, accelerated out of the apex, and it seems to be...
I don't know if it'll do it with a full tank, but the first time it had 3/4 of a tank, the second about 2/3. Being a new build, I'm trying to keep boost down below 5 pounds. That said, it's only done this after being on boost for 45- 60 seconds going up hill in canyons. I haven't gotten the...
The car runs great cruising around, on the freeway, and in the canyons ... most of the time.On uphill lefts in the canyons, it stutters, idles but won't rev, and then sometimes stalls. If I turn the car off, wait 7-10 seconds, and then turn it on then everything is good again. It feels like a...
Sorry for the vague post. The hub was bolted in place to the unsprung strut, and the axle was going through the hub, yet the axle would slide in and out, in other words obviously not "clipped" in.
I just got a free things left to button up, but I'm kinda stuck. There are there things:
Front axles are kicking my ass, see other thread
I have a black rectangular box with two vacuum lines, one in and one out, which is currently (and most likely incorrectly) mounted near the firewall...
Is there a trick to getting the front axles to click in place? She's getting dangerously close to running, and while all the bolts on the wheel side line up, the passenger side at least (haven't started on the driver's yet) still seems to slide left and right if I unbolt everything on the wheel...
