So I'm driving yesterday, decide to get on it with four ppl in car. Takes off shifts down to first, starts boosting like normal. But it's moving slower then normal, I assume it's the extra weight. As car approaches redline (5000). Cel starts flashing. I back as soon as I notice, it flashes a few (2-3) times mire, then it's gone.

I have a scangauge, and even hit the scan button while it was flashing, no codes during or after.

I'm positive this can not be good.....Help!

 

that happens when I use my 2step, one of my boys has the wot box and that happens to him. In my case it will flash 3 or 4 times then stay on, check the codes and i get a blank and then get p0000. on the wot box it flashes then goes away with no code. If not using anything like that I would think it may have something to do with the coil packs, loose connection with managment, or maybe just some bad gas. IDK what els causes the cel to flash like that, like i said iv only seen that when using 2step

 

pretty sure a flashing cel during wot is misfire

 

If ur flashing cel at wot.

Your missing at wot. thats very bad. Stop check plugs. Check tune.

You have issues.

Its kind of like a HEY IDIOT. STOP WHAT THE ____ YOUR DOING light!

 

Yeah that's what I was worried about. I know my tune is rich, so probably bad plugs. Will check today and report back.

 

Extra weight will make it go through your map cells slower too so if it normally would skip over those cells due to faster revving because of less weight, then you might not have noticed it before. Running rich is no good either lol. Check plugs and tune.

 

K so afr turned out to be a tad on lean side 12.3:1 avg in open loop. Pulled plug on cylinder closest to drivers side. Looked good minus red coating. Had some black on porcelain, but definetly not the worst set of plugs I've seen. Help?

^ Good info.

 

richen it up a tad and see where that gets ya. also what kinda timing are you pulling at full boost?

 

Will do later this evening and report back. I know my tune was done when it was cold weather now it's summer like. I know I need to retune but anything specific to watch for when changing from winter to summer?

Crush I pull 7 degrees at full boost right around 7psi. I plan on pulling at little more since it is getting warmer out.

 

you maybe be pulling too much...

iv been playing around with the fic for quit a while and always pushing it just to see what i can get away with...so far iv been able to get away with pulling a max of 3degrees @ 8psi and tappering with a wot a/f of 11.5.

I suggest adding just a touch of fuel and try out pulling 4degrees @ 7psi and tapper it till you get comfortable with everything.

 

just saying i could prolly stand to take out even less timing on my car but im fairly happy at the moment at were i stand....I will push it more and more in the future.

 

just want to add that i dont think that the 7degrees of pulled timing is the exact issue, iv done the same thing in the past and didnt quit have that issue.

 

Alright I'll look into it. Probably change to a total of five and change the progression to the five.

****four not five.

 

Happened again. I'm worried it'd trans problems. Three times total. All in first gear pulling out. This time on a 11.5 tune Four degrees pulled. Flashed until I shifted to neutral. No code during or after. Help!

Car is auto.

 

what plugs are you using? stock? 1step? 2step? part number?

 

1 step NGk brleix7 or something like that

 

ok so bkr7eix-11 correct? try swapping to bkr8eix (2step colder). how much boost are you running and what turbo? intercooler?

 

7 psi intercooler 18g would a slightly used set of them be ok? I have a spare set.

 

hmmm...your not really on the level for 2step colder plugs but try em out anyways and see if issue comes back.
