i ran a 12.4
mph was 109.45 <----something wrong
60 foot was 1.8 on nittos no traction
only made 2 passes first was at 12.6 at 108

here is my setup

383 all the goodies soon to get a 200 shot :-)
loyde elliot heads flow 279
comp cam 230/236 114 lsa 550.
10.8 compression
stock lt1 intake no porting
58 tb
hooker headers to hooker exhust
comp r lifters dont know if there preloaded right
4l60e 2800 stall
3.23 gears

if you notice my timing is jack up pretty high and im getting knock and my fuel is rich by o2 readings. i lowered the timing today and am going to get it on the dyno soon. does it look like i have any engine misses or any other problems

thanks guys

im no pro, but heres what i think.

you have a little knock at idle, i would bring the idle timing down to about 29, it looks like its sitting at 32 and youve got .6 degrees of knock.

i would bring the timing down about 2 degrees across the board at 90 kpa to 100kpa and above 5500 rpms.

the IAC counts are way to high there at 132 need to be at baout 35 to 45. need to crack the throtle blades open with the set screw on the TB till it brings the IAC counts down.

you also have alot of knock from MAP you need to disable all the burst knock from the sudden changes in MAP, theres a knock retard VS MAP table, use that one.

and i think you have a lazy o2 sensor on the pass side.

sorry i dont have longer to look at it for you. thats just my best guess

You look to have way too much timing.. maybe 4 degrees too much. Dont appear to be affecting KR though which id expect with 42 degrees!

Also, your MAP is reading low. You should be seeing MAP readings equal to taht of the pressure outside and you are showing low 90s most of the run.

Make a note your MAF is reading about 315 g/s at 6300 rpm. You can sorta figure what kinda power you are making with that figure but i dont exactly know how.

I think I may have bought something from you before... could've been some seats... don't know.

Anyway, I didn't look at your datamaster files, but it would help if you posted or emailed me your current tune file so I could take a look at it.

EDIT: Just looked. Definetely way too much timing.

here you go

i have changed the timing back to stock 95 kph table in this file
is the car running rich ????

if the map is low could that mean my comp r are to tight or too loose

no i talked to you before about a tranny problem. turned out i loaded a 94 software before and i have a 95 made it go right in to limp mode

the timing issue never got knock before on the street maybe bad gas. i thinking that theres too much fuel and it is cooling the chambers then effecting the amount of timing im running
