It's not really an issue, I just want to get mine working long enough that I can put it in the install instructions I am writing. Normally I'd tell people to avoid using the FCD feature anyhow, any halfway decent tuner can get the same power out of the thing by tuning the WOT setting.

I am talking with the guys at FullThrottleSpeed every now and again, but we're both busy, so it'll take a little while to get it dealt with. This is the only feature that doesn't work on my unit.

No worries. Mine works great. I hit fuel cut at about 13.8 psi currently, and I can tune that up or down at will.

The one thing that is odd... it sometimes takes longer to start now - like 4 or 5 tries, then it goes. With my AFM, it starts right away all the time. I may be able to tune this out as well, I just haven't gotten around to it.

One thing is for sure - stock CT26 and stock fuel with the boost set to 13 psi goes like a raped ape. It's shocked the hell out of quite a few people who think their car is fast. :)

Did anyone do any measurement comparisons of the MAFT to the Lexus AFM as far as total sq inches.

Nope - but the Lexus flows 25% more air, we know that, so that should put it at about 5.15 square inches. Notice that it still doesn't compare to the smallest MAF... If anyone has a Lexus floating around, they could measure it for us.

awesome... can't wait to see your numbers + 1/4

i think i'll just ignore silly new zealand that's stuck in a "i don't wanna upgrade" hole and buy a maft LOL

Good plan. I'd love to hear his reaction when presented with another car that uses this successfully. Given the reactions to date, I fully expect him to bury his head in the sand and pretend you don't exist! :wtc:

Seriously, though, it seems less of the "I don't wanna upgrade" syndrome and more the "it's impossible to invent something superior in the 10 years since Reg pioneered the Lexus AFM upgrade" syndrome.

Have you tried enabling the startup enrichment feature on the MAFT? It seemed to give me some pretty speedy startups when my car was still running :)

grim you are my hero :) very well said on all accounts.
btw, my maf (impala new from ft) has the honeycomb not the screen like yours.
i'll let you guys know how it does on my car as well.

t61/custom mani/tial gate
680cc/afpr/maft in blow thru/afc
built auto/3400 stall

will be interesting to see how it does on a stock turbo/fuel vs upgraded.

I'm in a research phase, and it seems all the threads I've found stopped a couple months ago. Has there been any headway made since April? I was in on a MAF setup from SplitSecond for the Mk2 nearly 2 years ago that had high hopes but has yet to turn any solid positive results, so I'm biased towards skepticism. I'd like to hear some good solid stories, but everything I've read so far starts out w/ praise only to later include some minor issues, then the thread dies. Is this another of one of those threads? Did the starting issue ever find resolution? Do my questions now suddenly sound like the end of an old Batman episode?

what did you want to know Moorman? I have one in my car and I like it. I just think you should run a SAFC with it. You can swing by anytime and mess around with it and my wideband in my car if you want. I live pretty close to you and the only other person that I know of running one is Aaron and he likes his as well.

Yes, but you've reported mid-range lean issues and inconsistencies in tuning in other threads. Have those issues been cured? Or are you running mostly fine, dealing with minor issues as acceptable to you as-is? (BTW, none of your dyno chart postings show as images anymore. I can host them if needed.)

I'm rediscovering what a finicky beast the 7m can be, and eyeballing the AFM as a potential source of....finicky-ness. Considering I'm on my 3rd AFM, I'm looking to stop the hemmoraging from my wallet somehow. This swap has already cost me *much* more than budgeted due to so many disfunctional peripherals.

I've been running mine for quite some time. It's allowed me to push the stock 440's to 17psi with no problems. The only issue I have had with it is the built in fuel cut defender feature - which I might have a solution for, I just haven't had the time to wire up a cable and give it a try. This should not be a consideration, most people will want to disable this feature anyhow.

I am very happy with mine.

I take it then that you solved your 'harder to start' issue?

I have no interest in venting the BOV to atm, so I'm more interested in your setup since you seem to be one of the few running draw-through. The setup sounds good, but again, I'm hesitant due to my past experience.

then you will be happy with it moorman. I think my a/f's are due to blowing off to the atmosphere. Draw thru is pretty much plug & play. Talk to bigaaron as he is running draw thru with great results and no problems. I will pm you my dyno charts.

Heh... forgot about the harder to start issue. It only happens when I have the climate control turned on. Every now and again I forget and leave the climate control on - then it's hard to start, I turn it off and it starts on the first try. :)
