Well after a whole lot of driving my meth and tune is finally done thats so Quicksilver on here. Got to thank him for sure for hooking me up with a tune. Had a few picky things with the car but in the end it seems to be running really strong now. Thanks a lot.

JimzSS

Sweet, get some 1/4 times. Me=envy

chad463

hopefully some 1/4 mile time in a week or two.

Zekdemos

was nice to meet you even though i had to get you to stop lol.

chad463

ahah yah it was awesome, I was like hey look another cobalt lol. Then I heard the exhaust so I knew it was you lol.

QuikSilverSS

Try those Zex plugs I gave you, that should help with the blowby we were getting on the 2.79" pulley! Ya yours runs strong and safe, we will tweak some other spots when I am down your way again! I am gonna work on dialing in the idle better on both our cars, I will have the tune file emailed to ya hopefully this weekend!

Zekdemos

yea i could tell it was you when i passed you guys on the highway becasue of the hood. btw i got the coils in and it ran like **** i had to take the plugs out and wipe eveything down now its running good again woot so hopfully i can get my 2.8 on.

chad463

awesome, yah I will try them plugs today and see what that does. I did a few pulls on the way home and there was no hesitation at all. The idle is a lot better then when we started though.

Kibosh3

what does your afr look like? and how much of an increase in timing did you give it?

QuikSilverSS

Its running between 11.2-11.7 a/f ratio from 2-7k, 22 degrees timing advance with no knock. He is running the 5gph nozzle and is spraying through a throttle body spacer, devils own progressive kit. We can go up on the timing and lean it out a bit more in the midrange for better mid range pull, right now its nice and safe under wot! Didnt want to push it to much with the tune.

Before he was running the stage 2 timing table, with 3 extra degrees added when not under boost for better throttle response...now upped the timing to 22 degrees under boost!

Kibosh3

very nice ...

chad463

ahah couldnt have said it better myself. Changed the plugs out and the car feels much better now. Thanks for them plugs, you were right on what the problem was lol

QuikSilverSS

^^^Glad to hear that solved the problem, as mentioned I will tweak the rest when I am down next, we can strengthen the mid range a bit and could always add a degree or two more timing.

Kibosh3

ngk bkr7e plugs were no good for your set-up?

reason i ask is because the zex plugs have quite a bad reputation....

chad463

yah I was getting bad hesitation under wot with the NGK plugs but its all gone with the ZEX

QuikSilverSS

I ran 5 differnt gaps on BKR7E's and the zex have been way better than those, one person had a bad experience on this site and everyone was against going zex plugs, i have ran them 2 years with zero issues.

He was getting blowby because he should have had the gap set @ 0.035 instead of 0.040 with his 2.79" pulley, the NGK's are good just not as good as the zex IMO.

He was getting mad hiccups during wot throttle runs in 3rd after 5k becuase of the plug gap and the amount of air coming into the cylinder. Data logs showed nothing during these runs however i thought that was the reason as it happened to me.

btw awesome lotus

Snakes709

just curious. James at raven's said he is putting new plugs in my car when the car is being tuned, not sure what brand they are. But where can u get Zex plugs at? Just incase i have that problem in the future

Zekdemos

roadrage performance in cap breton closer to you but only place we could find them semi locally

Snakes709

cool, thx...hopefully the ones james is putting in will work good. if not ill get a set of those ones

QuikSilverSS

As long as ther gapped between 0.035-0.037 you should be good with a 2.8" pulley. My second choice to the ZEX would be NGK BKR7E's

chad463

yah every car is different so he will have to play with the gaps a little bit. I am thinking when you come down to Halifax I will get you to lean me out a little bit I am throwing a rich code. SO I think we can play w ith it a little more.

QuikSilverSS

Ya i am getting that same code on mine, i will take a look at the long term fuel trim and short term fuel trim, let me quess only when you are at idle at a stoplight? WOT i am perfect just this dumb code! is it P0172 ?????

chad463

yah thats the code. I think its only when I am at a stop light, it still runs good though lol

CobaltSC06

speaking of tunes, I just bought a used stage 2 kit, would anyone here with hp tuners like to make some $$ and install it for me (im very mechanically inclined) and reflash my pcm?

QuikSilverSS

PM'd ya on that
