2step=detanation

can a 2step rev limiter cause severe enough detonation if any to turn spark plugs to this

i used it for the first time last night and during the race it started to miss real bad and afterwords if i gave it any throttle past 1/4 it would start missing again.

2step doesn't cause detenation it just retards the timing to spool the turbo.

[sweatygrundle]

depends on the 2 step set up not all just retard timing. the setup in the aem there is a 2step and a seperate antilag. the 2 step cuts ignition and fuel on alternating cylenders and i have read stories of na motors popping from 2 steps but im not running anywhere that much compression

[Kelvin]

antilag is a 3step, which is what I prbly described. my bad.

[sweatygrundle]

ya the 2step setup requires a ignition cut rpm and a fuel cut rpm. the setup to spool a turbo just retards timing. im not sure if this caused it but the only other thing i can think of is the 91 octain i put in wasnt 91.

before i tuned it 2 weeks ago i was running leaner in alot of places on the map and my ignition was way to far advanced. hell i added 2* for vtec and fkt up and added 4* for spray and never had this issue. now i took out the 2* advance for vtec and removed 4* for spray and i get detanation that melts a plug. so it eather happened during the 2 step or it was **** fuel.
could running to rich cause this?

but durring all of this i never felt a knock or anything it just started missing. so thats what is making me lean twords the 2 step causing this

[toom1h]

replace it and do it again, if it doesn't, then your answer is no

[sweatygrundle]

thats my plan im also gonna fill it w/92 from a differnt station. but i think i should still pull the head and see if there are any pieces of the electrode in there still

[toom1h]

or just leave that plug out and crank it over a few times, usuallys blows out any **** in there. (broken up carbon, etc)


and you might want to try 93

[sweatygrundle]

where can i get 93 around here the highest ive ever seen is 92

[toom1h]

bah ****,,, you'll have to wait for someone else to post that. I can't remember at the moment.

[Daga]

don't kno of 93 in lincoln

[DSMMIKE]

no 93 in lincoln. and i dont see why a 2step would cause detonation in an N/A motor. ive only ever seen like one or 2 counts on my 2 step and i built 8+lbs of boost off it. im willing to bet it is from spraying and running lean

you have too much money in you plug budget.

[Coupelx]

are those platinum plugs? if so theres your problem.

[Kelvin]

93 on the north side

[sweatygrundle]

no platninum. platinum is crap with nitrous. they are the zex nitrous plugs

they are only $25-$30 for a set of 4. thats not to bad if i had to buy 8 i would be a little more anoyed.

oh ya i have also had these in the car for 35 to 45k miles so that might have somthing to do with it too.

[sweatygrundle]

well i picked up a new set of plugs. I had to buy 6 because speedway is out of the 4 packs and they wont be getting any more, so i will be going back after payday to get 6 more so i have 2 extra sets. anyways i did another compression check cold and they all ended up the same as before, as expected. so i said ****it on pulling the head i figure if there is no damage then that will cost me $98 to replace the gasket and if there is damage then what the hell is pulling the head going to do besides cost me another $98. so i putt the plugs in and took it out for a drive. no problems at all so i said ****it again and did a few 1-3rd pulls with spray. and no problems again. no smoke no misses nothing. after the last one i pulled over to pull out the #1 plug to take a look at it and nothing was out of the ordinary.

when i got back i did a wet compression test and all of them read 240-245. that tells me the #1 cylinder is a little weak in the rings but less then a 10% difference is nothing so I'm not worried about it. I'll just check it again in a week or so see if its changed any.

so i think the entire problem was started from being on the 2step to long. I remembered today i found a post on some other site that said sitting on a 2step for to long can cause the dead cylinder to start sucking oil threw the rings. thats probably what happened then. so when i sprayed all that oil caused it to detonate and melt that plug. so.

yaaaaaa no new motor and i beat a couple of cars running on only 3 cylinders

[Kelvin]

not bad


keep in mind a 2step does not cause detenation.

[sweatygrundle]

well i think if it fuel cuts at the wrong time it might. your turbo 2step just cuts ignition. but i think in this case it just sucked up oil past the rings and enough accumulated that when i sprayed it detonated.

[DSMMIKE]

no actaully our turbo 2 step cuts fuel and spark

[sweatygrundle]

ok so i was wrong

[srt-4_uk]

my 2 step only cuts ignition. My plugs are fine.

[sweatygrundle]

mine cuts fuel to. so i need to go into the settings and set the fuel cut part of it to an ungodly high rpm so it will never reach it.

[srt-4_uk]

it sounds cooler when it does not cut fuel.

[sweatygrundle]

ya, so ive read lately. you can be super rice and shoot flames

[Yngvar]

shooting flames ftw

[srt-4_uk]

That is how I roll.

[sweatygrundle]

what did you just run out and make that

[DSMMIKE]

antilag ftmfw cant wait till i have dsmlink. launching under 20psi of boost ahww skeet skeet

[srt-4_uk]

No, it has been on my photobucket for quite some time. It is nice building boost off the line but Dodge accidentally installed the axles in the wrong place so I spin everywhere.

[sweatygrundle]

lol i'm not making as much power as you but i know what you mean. using spray its there the second i hit the gas, so i tend to spin alot to. i did put on a traction bar and that did help quite a bit

[C.J.]

A fuel cut 2 step could easily cause that kind of damage, I don't think it would be specifically detonation related since it should not cause pre-ignition. But the motor put under a load with fuel being cut is going to have some crazy lean symptoms and could melt some plugs.

[86Shelby]

you have too much money in you plug budget.

That's the truth. I felt dirty for paying almost $2 a plug a few weeks ago to replace the ones I borrowed from Adam.

it ended up costing me $37 after taxes for 6 of them and im going back for 6 more so i have 2 extra sets, sense they only have them in packs of 6

[DSMMIKE]

$1.50 ngk coppers ftw

[sweatygrundle]

i wanted to play it safe and get somthing with a really short ground strap. and i didnt feel like looking threw all of what autozone had. cuz all the **** they had listed for my car wasnt working for me
