Re: y8 tuning tips needed
 

ditch the afc and get some better management

Re: y8 tuning tips needed
 

ide liek to get hondata but too much $ the afc works for what i need but i need a good dyno/tuning this spring

Re: y8 tuning tips needed
 

Convert to obd1, lose the v-afc and get chrome or uberdata, chip your ecu then find someone to tune on dyno. Safest cheapest way to go! :)

Re: y8 tuning tips needed
 

if your going to suggest something, atleast spell it right. but i would find someone locally that knows what their doing to help you out. what is your location?

Re: y8 tuning tips needed
 

Sounds like you don't need advice. You've got it all figured out. ::)

Re: y8 tuning tips needed
 

at least ditch the FMU and just use a set of 450 cc dsm injectors with your afc, its called the afc hack, you hook up the afc exactly the same as you would otherwise, and throw in a set of big injectors, and dont even use the fmu, then hook up a wideband and lean the big injectors out for idle and cruising to like 14-15:1 and then get them set so you run like 11-12:1 in boost, this will also require a bit of leaning them out, just not as much as in vaccum, you are better off to do this than to run an FMU,AFC, and stock injectors, however, if you want it to be right its gonna have to be widenband tuned (the afc) but really for the afc to do anything good the way you were gonna set it up, it would need wideband tuned anyway, but using an afc with an fmu and stock injectors is pretty much worthless if you ask me..... :y

Re: y8 tuning tips needed
 

sell your fmu and afc and you'll have enough money to buy a chipped ecu and some 450s :6

Re: y8 tuning tips needed
 

i got 2 sets of 450's and i dont wanna run them the run too rich. i got 00 gsr injectors in there now with my fmu and vafc. it works but i need a good tuning day this spring. i started my y8 build up today and ill update it later on this winter.

Re: y8 tuning tips needed
 

of course the 450s are going to run rich, you need to tune them. Once tuned there gonna be able to support the fuel needs better then those GSR ones, because im pretty sure those GSR injectors are just 240cc like the ones in the D series.

Re: y8 tuning tips needed
 

Put a real turbo on it, ditch the afc, and keep up with your oil changes. If I ever ran a Y8 oil pump again I'd have a whole pillar of oil pressure gauges. ;)

Re: y8 tuning tips needed
 

do the y8 oil pumps go out alot??

Re: y8 tuning tips needed
 

why in the hell do you have a vafc and an fmu? Anyhow, sell me one set of your 450's

Re: y8 tuning tips needed
 

There are of course y8 motors with tons of miles on them that are running fine, but I've spun a bearing in my old y8, my friend went through 3 Y8's that developed spun bearings, and if you look online you can usually find a couple y8's with bad bearings. The only cause of spun bearings are bad oil changing habits or insufficient oil flow. I can't say they are garbage for sure, but I don't trust them in anything performance oriented.
