Can adjusting my TPS sensor lean out? how can I lean out my system?
 

someone said that if your tps sensor is not set to .45 volts that it could raise your fuel curve. I'm running sticking rich bad. What can I do to lower it? Will turning the distributor lean it out?

btw I have d16z6 with 450cc's controlled by a fields controler at -30 straight across and thats the max - it will go. I hate to have to get new injectors but I will if thats the only way.

your injectors are to big, stock computer cant control injectors over 370, even with a vafc or the fields, get hondata or different injectors

looks like your fields can lean out your injectors enough to run... https://honda-tech.com/forums/images/smilies/emsad.gif

450cc injectors on a boosted D series usually need to be trimmed 35%-40%

ps. if u are turbo'd then turning up the boost will lean it out https://honda-tech.com/forums/images...s/emsmilep.gif

Stock injectors are 270 cc/min, right? If you put 450's in place of 270's, you will need close to -40% correction, and certainly more than -30%.

How rich are you? How are you measuring this?

Increasing the boost will not necessarily lean it out, unless the injectors are maxed out, or you have some sort of hacking of the MAP signal that's causing it to flatline after a set boost level. Otherwise, fuel flow will increase with airflow like it should.

who the fuck said you can only run 370's on the stock ECU https://honda-tech.com/forums/images...s/emhammer.gif 240's 270's and 310's are fine unless you have a way to control them. A vafc can control 440's and dont say it wont because I have been running this setup for a year now https://honda-tech.com/forums/images/smilies/mad.gif
