compression for all the cylinders are 140+ besides the 6th
its got a wade 1250 reground cam in it

extractors
standard injectors

Re: Need help on a tune
If I am reading this bin right the VE table looks a mess. Lets see what others say.
Re: Need help on a tune
yer its completing messed up is there anyone that could fix it up or make it run better
Re: Need help on a tune
Post up the cam specs save searching for them.
What's wrong with how it drives now? Could you post a pic of a spark plug end?

Re: Need help on a tune
spark plugs are new but the 6 cylinder was more burnt then the others and had no compression in that cylinder

Re: Need help on a tune
when it drives it feels like theres power but just cant reach it and when i give it just that tad more it doesnt improve in speed
it shutters and sometimes on idle it leans out and some rev ranges it goes to about 17+ on my wideband and once i touch the pedal it goes back to 12 and 13 and moves up and down to 16

Re: Need help on a tune
Wideband that's handy. Are you able to log this?
Re: Need help on a tune
yer i can log it if you want man but did you want me to get the car at warm temp?
Re: Need help on a tune
That's the go. Get it warm. Although a log from cold will be handy later on. Post up a log. So long as you're prepared to do a few logs ae can get it spot on.
Get the VE right first. Get some good target AFR's then ae will get some good spark advance then all sorted!
It won't happen in one log but stick with it!
