Went Stage 2 with EQT, not performing as expected. Logs included.

After much debate I finally pulled the trigger and went Stage 2 on EQT. Upon driving for the first time (after all warmed up) it wasn't what I expected. The car pulled harder in first through 3rd but then kinda fell flat at the end of 3rd onward, 4th through 6th felt almost like stock. I never got that "holy shit" feeling I was expecting though. I took some logs and it revealed a considerable amount of knock, but I failed to record IAT and a few other things. Long story short, today I took a good clean log and the car felt strong.

Currently I am running a downpipe, still stock plugs and intercooler. New plugs on the way (Denso IKH24). Idle is a bit rough although that was happening before the tune as well. My thoughts are IATs get too high rather quickly from heat soak, and the shitty plugs arent helping.

Yeah... no more WOT pull till you resolve this, the timing and KR is bad. Yes the iat delta are bad and they just keep
Rising but your ambients are low enough to where the heat levels would not be the main contributor to such bad knock.

I have about 20k on the plugs and don't know how many miles were put on them before I purchased the car, so the plugs will be the first change. After the plugs I'll post logs and see whats up, but im hoping it solves most of the issue. I know an IC is pretty much required for stage 2, but if I can hold of for a bit to let my wallet recover it would be nice :LOL:

If you went EQT stage 2 and didn’t change plugs to 1-2 step colder that is the first place to start and keep off WOT until that. Idle should be smooth on EQT; I was Uni S2 for 14 months and switched to EQT in April, idle has been considerably smoother on EQT v Uni.

my idle was super smooth on EQT tune. For sure get a set of plugs at least one heat range colder than stock, I recommend the NGK iridiums that EQT uses for their shop cars. having terrible plugs will cause all sorts of issues. no more WOT runs until you get some good plugs in there.

Sorry to budge in on his thread, but the recommendation to switch plugs is only for going EQT Stage 2? Any need to change it for Stage 1?

I'm still using regular denso IKH24 plugs gapped to (iirc) .024 with EQT E30 stage 2 - I had already bought them right before going to Uni 93 stage 2 around 6000 miles ago. Used the same version all through a year plus of Stage 1. All seems well.

Those are not just regular plugs. They are a heat range cooler and people run them on high hp applications all over the tuning world.

Ouch ya, can't go stage 2 without looking over all your maintenance items. That could be bad news. If the plugs are old and unknown, they are probably not gapped correctly either so could easily be the source of your problems.

was just about to say this... 1 step colder.

is to be mentioned though there are a few guys over 400HP using the ruthenium's and those are stock heat range, and they report no probs.

anyone know other options for 2 ranges colder that arent 150 for the set of 4?

5* at 5800 is aggressive? I know it's different fuel, but my friend's EQT "stage 2" e30 OTS hits 14.5* up top
when comparing a e30 ots log and 91 ots log from Ed he only looks to adjust the boost request .5 to .7psi throughout, so really all the gain is in the much higher timing requests, but yeah to me 5* seems pretty "normal" as a request on 91. granted I'm hybrid, but on my sneeky starting map (91) he's got me setup requesting 5.5 by 5500, and 10/11 by 6500.

@Supermoto Yes, the 3rd gear reflected the retard as your IAT increased and when on to 4th, your IAT flooded the retard. AFR was fine. Ambient was 61* and at 4th your IAT was already surpassing 100* and you weren't ever able to achieve the target torque. The cooling system just cannot keep up with the demand. Most definitely at least a +1 plug set & IC......
