Hey guys,

I know that this is probably something stupid that I should be seeing, but if you could please have a look at the two logs and maybe let me know what's up, I'd appreciate it!

So I got the car setup pretty good for cold starts, basic idle and cruise on SD. This is with a vented 1G (crushed/dodge modded) BOV and FP 4" non-recirc intake.

I went out today to try a couple of pulls to see what the WOT base tune looked like (using "2004 EVO8 GSR Ralliart" DA tables as a starting point):
At full boost (set around 25/26 psi), with meth injection M14 nozzle, I am getting zero or less timing and 9.0-9.5:1 A/F Ratios, but not seeing any knock, and no misfires...
The car feels extremely slow, like it completely falls on its face under WOT!

I've attached two short clips of a 2nd and 3rd gear WOT pull, but I let off around 6000 rpm each time because I could feel that the car wasn't making any power at all. When I look at the DA tables for OPENLOOPMAXOCT and TIMINGMAXOCT, I can see that the load rating is around 3.0, which is much higher than anything I remember seeing last season,

Any suggestions or advice is appreciated, and sorry in advance if I've done something completely stupid here (if you can't get the attachment because it's linked to the ECMLink site, I can email to you instead!)

Looks to me like it's bang on my friend. Look at your DA Tables and track your log, you are hitting what the DA Tables are aiming for.

You've got a bit of dialing in for your SD setup.

Yeah I know what you're saying, I have no issue with how the log is tracking what's actually going on....I am wondering why I am in such a high load range in the DA tables on a flat road pull in the mid-rpm range!

I just don't remember being that low in the table before, any ideas what could cause me to be down there?

There's no need to worry about why your are in that load table, its' not going to solve anything. Use the information and tune it ! I haven't looked at your log but if your DA tables are on stock fuel maps, then yup thats what its aiming for. Simple enough right ?

Yeah Reza, that's pretty much what Thomas Dorris from ECM was saying too. I will tune with that information and see how the car performs, thanks smile

I just looked at your log, add some timing back up top, and you can lean out the fuel to what your car likes. Your on a very weak timing map, running super rich!
No wonder it feels slow.

Ha-ha, what do you mean?? I figured 9.0:1 A/F and timing of -2.3 degrees made a boatload of power rotflmao

I will add back some timing and lean the car out to the point where the car doesn't knock or misfire, and go from there!
