help me please

---- was tuning last night and the car pulls hard as long as you dont get full throttle and 50% and it feels fast

thanx for the help

 

Get a PROFESSIONAL tuner to tune the car.

 

Injectors? When in boost/VTEC, requires quite a bit of fuel.

Get a professional tuner, such as Jarrod said. If your doing what I'm doing (fuxing with crome and learning your way around the program) start on an all motor car first. Less likely to break shit.

 

how many pounds are you running?wat size injectors are you using?and like they said def. get a professional tune as you would hate for your build to detinate with a s****y tune on it...

 

I'm the one tuning the car guys. Its not a fuel issue. Its having ignition misfires as soon as the boost goes over 5psi or so. Plugs are gapped pretty damn low. Its an issue with the ignition system. The spark is too weak to bridge the gap on the plug after vtec crosses and lets in denser air.

 

msd?

 

no oem new dissy yeah matt tried everything and yeah he know his sh!t lol

 

Yes, Matt Somewhat tuned my half ass setup sohc and did a very good job on working with what I had to work with (I came un prepared)..Nothing but good words about matt You'll see my hatch after I build the transmission and other stuff. I'm hoping for close to 500? Make it happen Matt!


What all have you guys done/tried?

 

im goin to change the wires if that doesnt work im gonna put a different dizzy on it

 

Same thing happened to my buddy. Don't know what it was though.
