Maf / blm numbers

[77tech9]

Finally after fixing header to turbo leak i'm chasing my low MAF numbers.

Idle maf = 3-4 when hot
Idle blm = ~131-135 when hot

Tryed putting a new o2 in, etc. Car runs good, but not sure about the AF 3 reading on the maf. Tryed another MAF and same numbers. I made sure there are no leaks anywhere in intake and vac lines. I'm at high altitude, not sure if this affects it that much.

I wouldnt worry bout it. BLM's are stable meaning the air fuel is correct.

I would care to know if the MAF numbers are going to 255 at WOT 16 PSi boost.

Or 20# of boost where we are located.
The idle MAF reading does seem low. Mine is between 5 and 6 at idle.

I'll have you look at it when you come down XLR8.

But I just wanted to get everything going good before we really put any major mods on it.

On a denso O2 at the track my blms would shoot to 160 at idle, but that was on straight leaded gas. I changed it last night and drove today and it was ~119 crusing highway and ~128 idle. Maf would sometimes be on 4 or 3.. so i dunno.

Alky will be next so no more of that lead.

I'll see you on the 29th. I'll be the guy with the black car.
