Down, what is ur setup if it is similar to mine maybe we can figure this out

Maft pro tuning question
- Thread starter 89turbotoy
- Start date
ok let's start from stage one. Why would i have to add fuel?
maybe something in initial setup is wrong?

I have a walbro GSS341 with a perminent 12v feed
stock 440's fuel pressure is 25psi with vac
stock ct26 at 13psi
main scale is -2%
low loads are all about -3% to keep vf@2v
mid load I have at +10% to max out the ecu adjustment so it will drop to 13:1 as soon as I make boost
high load -2% to -3% up to about 4800rpm
AFR is around 11.4 - 11.8 on WOT
My only thought is your fuel pump isn't up to scratch or your regulator isn't upping the pressure as you come on boost.
now i have a code 35 no hac sensor signal, is this normal or should i recheck my hac mod? (89+ car)
Why even run the HAC to the MAFT Pro? Feed it a set voltage signal from +B or VC (NOT WITHOUT THE PROPER SUPPORTING COMPONENTS! of course)... no worries about the MAFT Pro starting up too slow then. 
Does this error not cause any operational differences? As long as timing's not pulled it really doesn't matter, but I'd like to know. Especially since there's a way to take care of it without any codes.

Same for dealing with the THA error code.
