afc tunning ?

[raredreamz]

any idea what my basic settings should be at? fuel wise like - or + fuel % ?
62-1
450cc injectors
at 12 lbs
stock maf in a suprasport housing
full 3 in exaust ?
walbro 255
aeromotive fpr set at 45
plze any help with the high low fuel percent ?

 

[Rennat]

add fuel. aas you have a bigger afm and bigger turbo, but stock injectors...
set it at +15% across the board on high throttle and go from there.

you dont have a wideband?

 

[grimreaper]

you dont have a wideband?

:3d_frown:

 

[raredreamz]

i had one but it was stolen out of my car about a month ago.,.. they left everything else so i cant be to mad i have like 200 to spend right now on one im just looking around for one

 

[raredreamz]

but any idea what my low throttle at?

 

[grimreaper]

You should take the lex afm OFF and leave the afc at all 0's until then. Why would you tune blind?

 

[raredreamz]

this is true i dont really want to tune it im not beating on it just drive it to work and school and want it to be somewhat on sync

 

[suprafanatic]

well you wont know what on sync is with out a wideband.. there really is now way of telling if your running to rich or to lean at this point.. my guess is lean with the smaller injectors

 

[Poodles]

He's going to be running lean with the suprasport AFM housing and stock injectors.

Your engine to do what you want with, but if you don't have a wideband to setup the fuel pressure and then trim the fuel, you WILL go lean.

just get it tuned, if your still looking ill sale you my afc when i get enouff money for map ecu.

 

[rumptis]

You can't tune safely without a Wideband...don't even try....it will end badly!

 

[raredreamz]

ok well i just hooked the afc up and it wont let me go over like 3 grand when its hooked up. i tried the fuel at zero then +7 then +15 but no change? any idea what wrong...i unhooked it and it is fine

 

[figgie]

leave it unhooked.

More than likely the wire for the AFM signal is not porperly connected.

 

[isnms]

Do -

...i unhooked it and it is fine

- That.

 

[raredreamz]

good news lol i figured out that the sensor type was on pressure and not Karmen lol but hooked it up and it helped out allot just added 3% across the board and runs amazing

untill you blow the motor..


Btw...people here don't like when someone asks questions on what they should do, then the op just ignore the advice given...when you blow your motor don't come crying to us for help as we already tried.

 

[Poodles]

Lean usually runs great until it melts something...

 

[raredreamz]

yeah it was running kinda rich and shooting flames in between shifts so i know it wasent lean.. but i then unhooked it and put the reg afm back on so thanks guys ill just wait untill i can afford a wideband
