ECMlink New to ECMTuning/ Log reviews

[Chevy2g3]

--------------------------------------------------------------------------------

Hello all! I've had ECMTuning for a month now but I just installed it yesterday. I'm totally green to tuning my own vehicle but I'm eager to learn and will accept advice. I have a few logs I made tonight. One is an idling log, the other a cruise and finally a part throttle pull on the freeway.

The mods in my car are: Garrett 60-1 turbo, FIC 650 injectors, HKS 272 cams, Kiggley beehive springs and retainers, 1mm oversized Ferrera valves, port and polish, ARP Head studs, walbro 255 fuel pump, 3in turbo back exhaust, Punishment racing 3inFMIC, Greddy Type RZ BOV, AEM Uego wb.

Please go easy on me since I have never done this before. Again thank you all in advance for your help!

Yea, you have some work to do. Throttle pos is at 4% yet your idle switch is engaged. Tps must need adjusting?? You dont have anything useful logged. Try logging a bunch of other things. Since you have 272 cams your airflow per rev IVE HEARD, is supposed to be around .31. Your maf comps are way off the charts. You really need to log the wb.
That said, you are safe cause i noticed almost zero knock. You just dont have a great tune yet. When i added the pte 5858, pr fmic, and BC 272's my idle is tough to dial in as well. Though i could have boost leaks or rather vac leaks. Its not easy but yours is very far away from doing WOT pulls. You have to log combined ft, mafraw, and other things. Go to ecmlink.com and watch videos and read, read, read.
Your on your way, congrats bro.

What other things should I log? I dont have my wb hooked up to the ecu yet because I'm not sure how to do it. As far as a/r goes I'm still running pretty rich. My wb displayed 10.0 flat.

Your aboslutely right I need more knowledge. I will start watching the videos tonight because honestly half the stuff you mentioned to me sounds like a foreign language.

Lol, we all started somewhere. And i am by no means a pro. My car is just now breaking in so im still running a safe 12lbs. Its about ready to tune though but the more you know it seems the more shit goes wrong! GL and like i said, watch the vids and read the ecmwiki. Itll show you the pin out and the aem gauges require a bit of calibration to work well with link but tons of others use it so im sure its fine.

Thanks man. I do have a question. I read the wiki on the AEM WB install and I need to know do I splice the white wire from the wb into the o2 sensor pinout (76 I believe) or do I cut the wire completely and wire it into the pinout? It didn't seem to be very clear to me. Also my wb is located 6 in from the rear o2. Is that a problem?

 

[boost97gst]

Your question about wiring: im not the guy to answer. I have a LC1. I do know if your keeping your front o2 sensor you have to use a different pin. The easiest way is to remove front o2, put your wb there and simulate narrowband in link. Just a thought..
As far as placement, yea its OK, but not optimal. The further back the wb is the slower it is to respond to change. That said, there are plenty of people running the wb in the rear o2 location with stock front o2s.

Ok so I put in some work before work, during lunch and after work. Changes made: After I watched ALL the ECMTuning demos I applied everything I learned and I came up with these logs. One is cruising, the other is idle and I have a 3rd gear pull. Please feel free to review them and tell me what you think. I'm already tracking the 2 degrees of knock in my log and it will be dealt with in the morning.

I was able to get the AEM WB dialed in pretty easy. Maybe I'm just lucky sometimes Also my airflow per rev is low for 272 cams, but according to the demo video they said not to stress it too much as long as your fuel trims are fairly solid. So any help or advice given will be greatly appreciated. Thanks in advance!

Here's the cruise log

 

[boost97gst]

Idle: looks pretty good from what i can see. Its idling a bit high for my taste but whatever works for you.
Cruise: Needs mafcomp adjustment run. That way your combinedft will be near zero when in normal cruise mode.
The pull: HOLY SHIT, is that even remotely accurate? 39psi??? Damn i bet that thing hauls ass .
Again tho, not bad looking at all. You can tweak your DA tables if you want but you barely got any knock even at an insane power level. I think link may be a bit off with the hp estimate there. It tops at 343 or something like that. If you really are making that boost level witht hat turbo i would think its a LOT higher.

The boost is WAY inaccurate! It was 22.5 psi. I can't figure out how to fix it for the life of me? I have it idling that high because of the 272's so I want a little more vacuum. I'll use the data from the cruise log to create my mafcomp adjustments. BTW, how accurate is the horsepower setting on link? I'm a bit excited to see that much power being made. I would like to speed up spool a little though. Should I add some timing during spool up rpms?

BTW bro thanks for all your help on this. I'm a little broke from buying parts so I don't have the cash to pay a tuner. Plus I thinks it's better to learn this stuff anyways.

ok, i DO know this: to line up boost est with actual you use the maf sliders. The car thinks its getting alot more air than it really is. So if you know you top out at say 22psi and link reads 39psi() then find the maf hz that its occurring at and lower the sliders around it. Do another pull and see how they line up. This is kind of cyclical cause then your combined ft maybe be just a tad bit off. But you prob wont notice it. Run maf comp first then do what i said and try to line up boostest with actual. The hp number will be much more accurate then, atleast from the knowledge i have on the subject.
I should finally get some time this weekend to tune myself and maybe i can help out a bit more. My pte 5858 makes an est 243hp(iirc) at around 12psi, you should be way more than that. We have similiar setups kind of. I believe links estimate, if airflow is set up properly, is extremely accurate. Its telling you whp. Someone did a dyno and compared it on this site awhile back. I was surprised. it was only like 5hp off!

And i really hope im giving you good info, there are so many others here that are link gods but they dont weigh in as often. It can be very time consuming i suppose and people are busy. Im fairly confident in the info im sharing. Ive seen it first hand.

 

[Chevy2g3]

Dude I appreciate all the help you've given me. I did the maf comp for a portion of the inaccurate reading just to compare it side by side. It did start to read accurately but my Lin wideband was way off(12.5 when the actual gauge displayed 10.3) plus I started to get more knock (6 degrees). I know it's a working progress but I'll keep plugging away and post more logs as I go along.

the ECMLink forum is very helpful. I noticed you posted there as well so I'm sure you'll find some good info there. I have really inaccurate boost readings with mine too my MAP is maxed out 0.0
