1JZ boostcut asoon as foots to the floor

[Azzamk2]

Running a haltech E6X, Put the throttle to the floor it just instantly hits what feels to be some type off cut! which makes makes it feel like a huge bunny hop haha but if i just keep it half throttle even abit more it will boost to redline fine

what can cause this?

thanks guys

You need feeler gauge and multimeter to measure continuity, i did mine a while ago and i'm pretty certain all the info came from here, have a search if you haven't already, if you have no luck i'll see if i saved it all on my other computer.. I do remember there being different methods talked about, but that's how i did mine..

As i understand it the adjustment is to configure the spot where the computer knows that the throttle is closed completely and idling. I only replaced mine because of issues i was having, tps was one of the codes i had. It didn't fix the issue

is boost line conncted to the MAP sensor?

or you need to look at enrichments, or even your fuel/ignition tables to see if there is anything screwy...
