sadly i will have to miss it.
and the unfortunate part is that that will be end of my auto-x for the summer.
The Coil is just too bad to put that kind of stress on it. I am taking it off on monday and shipping it to Ksport to get rebuilt. I am trying to go to Toronto this coming week so it will be good for me that the car will be out of sight out of mind. And when i get back hopefully the coil will be there

i possibly will be able to make one or two in the Pittsburgh area this fall.

timing is still a bit off.
got my A/F gauge today but AMCmoe forgot one of the wires in the package so i am trying to go pick it up from him tomorrow.
idle is a bit better than it was last night but it is still super rich and idles btwn 500-850 until eventually stalling out

monday is supposed to be a cooler day than the past few (95+)
so i am going to a local shop to get it tuned.

Mike, have you changed your 02 sensor ? Mine went bad a little while after I installed the cams...it's only like $35 at autozone for the universial 02 for our cars.

have you tried the ECU reset?

same o2 sensor. maybe i should replace that before i got get it tuned on monday.
after how rich it had ran since it first started, yeah i bet it will be or is on the fritz


i havent really done much other than set the map on the SAFC to different settings. trial and error basically.
i have it at 3% correction at idle which helped even it out. as of now it idles from 690-790 but usually stays btwn 710-780 if im lucky.
after a bit it drops down to 500 then overcompensates and peaks up to 1100 then back down to 500 and keeps going in that pattern until i level it out back to 700 by giving it a bit of gas
hopefully i can get the plug from AMCmoe today and get a better view of how its running

tuning done yet????

Hey Mike,

Well ya didn't miss much down there this weekend. Well I guess it would have depended on what class you would have run in. I was in HS and that was in the third heat. Most of us got one run in before it hit. Rain...... hail.... wind..... lighting........ it was nasty. So they called the third heat a washout. and sent us on our ways.

Met a lot of good people down there and I'm looking forward to going back!

Hope the tunning is going well.

well no.
had an attempt at a tune.

Here is the situation the night before, note i have the gauge now.
I tuned it a bit myself the night before. Put the Correction at 9% at 800rpm to lean out the idle. still stayed at 10
also tried to fix the 4000rpm+ problem where the AFR would go from 13.5 to 10.

During Tune (which i paid $45 and i could have done it myself)
we went out for a drive and did a street tune.
he bumped the correction to 19% or so and the AFR at idle only went up to about 12.
We also bumped up the correction at 4000k and barely made a change.

we are taking the valve off tonight. checking a few things and doing a trial and error run.


called ksport today for a new shock. takes 2 weeks to get it in

change the 02 sensor.

what are the specs of the cams you are running??

specs of the cams? or specs of the performance gain?

after a nice depressing talk to Stef and Dustin last night. We diagnosed and discovered the problem.
Valve shims.

The new shims that I had with the new cams are all different sizes and belong on different valves.
crap.
So this morning i have to gout out and get a feeler gauge, micrometer, and yes dustin a new o2sensor and measure all the gaps btwn the lobes and shims and figure out which ones need to go where.
looks like i gotta long week ahead of me

specs of the cams

they are 294s (overall performance grind)

they were mine originally, I posted about them here

with a quick comparison dyno

thanks for the info link batman. I had a feeling he might be going for those.

would be nice to compare dyno, when tiga is ready.

i have time to dyno it the next 2 weeks. im taking a break from the car for a couple days. Friday night im going at it and hopefully i can finish it by sunday. And also maybe get a new caliper and flex pipe in that same time period as well

well i took the exhaust cam off and measured the shims.
I got measurements from .1175" up to .1275"

while the exhaust cam was out i measured the valve clearances on the intake cam.
I started with the smallest feeler gauge .008"
it did not fit under a single one expect for the 6th valve. And on that valve i tried the next gauge and it did not clear.



next i am going to take the intake cam out and check the measurements of those shims
from how they look they seem like they are the same as the ones as i took out of the exhaust valves. lets hope not, because i need alot more clearance room than what im getting thus far

Exhaust Valve .............. .011-.015 (.29-.38)
Intake Valve ............... .007-.011 (.19-.29)
in. (mm)

thats a relief!
thanks dustin,
i was thinking that the gap needed to be a decent size bigger.
its funny because you cant even see a .008" gap.
it looked exactly the same as the one where the lobe was making contact

i doubt this is all going to work with the shims i was given.
the only ones on the intake that are giving me clearance are the shims that are btwn .116-.118
and i only have 4 of them. and they are all on the intake leaving me with 4 other valves that dont clear.

and all the rest are on the exhaust and none of them clear as well.

from .122-.1275
they dont clear at all.

all the stock shims go from .105-.111
the only ones from the stock shims i will be able to use is .109 and above.

i would rather not order any because they wont get here until wednesday. I mean...i SHOULD wait but i really dont want to.

SO!
Here is a note of where i am at with all the clearances

counting left to right on the valves as you go down the list
all measurements are in inches, my micrometer only does inches


INTAKE
clearance btwn .007-.011

SHIM GAP
.116 .008
.110 .010
.118 .008
.110 .016-17
.111 .016-17
.1175 .010
.109 .015

EXHAUST
clearance btwn .011-.015

SHIM GAP
.122 NO CLEARANCE
.109 .015
.109 .016
.109 .016
.1235 .008
.1085 .020-25
.122 NO CLEARANCE
.122 .008

_________________________________________________


This is a list of the remaining shims (excluding a few very small unusable shims)
.108 x2
.1085 x2
.124 x2
.1255 x2
.126
.1275x3


now...wtf do i do
