ECMlink Logging with WBO2 ......Finally

[RedEyeBanDiT]

I just installed my wide band, gapped my plugs, re routed my vacuum lines. Car is running great. I did my idle tune over and cruise log to reset my maf comp after I fixed some boost leaks. I don't understand why my Global Deadtime on my fuel table has to be so high to keep my combined fuel trim where its supposed to be. Anyways I made some small adjustments, and here is my last log. 22-24 lbs of creeping boost. Advice is welcome.

Update your profile.

If you are using 560cc injectors you should have global at -25.8 instead of what you have listed (-17.6). Your deadtime isn't high at all. Mine sits around 700 with 1250cc injectors. Use only 1 table, either the sliders or the DA table, not both. If you use the DA tables then keep the sliders zeroed out.

Your speed seems a little odd on the graph and after your pull which hopefully is on a track, you are at 0% throttle yet you are still showing 14.7 on your wideband. On decel, you should have fuel cut which would read a max lean on the wideband.

I appreciate your opinion liquidx. My global setting was set the same as the tutorial as ecmlink shows. Supposedly the evo injectors flow 545, stock fuel pressure is 37 lbs. and it automatically calculates -17.6%. So why do you say its wrong.

As far as the fuel and timing sliders ago, I will zero them out. However, when I continue to tune for more horsepower once I have the DA MAX OCT map dialed in can I use the sliders to tweak it instead of changing the timing values in DA everytime ??

Also I do not know if you noticed, but I changed my target a/f ration in DA as well. Is that approriate ?

BTW I have no Idea why my wideband is reading that. I noticed my ecu will read 15.0 fluctuating while my gauge will be be around 14.8 about 2/10ths off.

I'm just going by the size of the injector. I don't go an research to find out if they flow differently than what is stated. That's why I prefer FIC because they are accurate. You could always just go and get them flow tested to be sure of how they flow but that's just my opinion on how I would change global.

And correct, you either use the DA tables or the sliders ONLY. It makes it much more accurate with your tune that way. If you say you have your tables where you want them and the Move the sliders, then you dont have the table where it should be. This applies to both fuel and timing.

Also realize the AFR table is for open loop mode only. You won't affect your idle AFR using the table unless you lock the ECU into open loop mode.

Then I would loom for another opinion as well as on decel you will enter fuel cut and should show max lean.

I turned down my boost, The boost seems to just come on later rather than sooner, 15 lbs around 3500 rpm and 20 lbs around 4500 rpm and it creeps from there to 23-24 lbs. I do have a boost leak at the throttle body seal.

I messed with the open loop table, flattened out my timing and fuel sliders, upped the timing up 1 degree because I had it at 4 deg base timing. These pulls were at the track and temps got real hot, it was 95 degrees outside. Heres my last run on 93 octane. Plugs are Bpr6es gapped at .025.
