4agze w/ apexi S-AFC

Has anyone got one or tried playing around with one on a 4a-gze?
In one of the Hot4s mags they adjusted the air/fuel ratio on a 4agze with a mircotech comp (but this thing should do the same thing, right!?) first untuned dyno run got 77kW at the rear wheels (4agze in a KE Corolla. Then they changed the ratio to 12.5:1 and pumped out 100kW@wheels. The issue is the one with the Osman WRX on the cover.
For those of u that don't have the issue, the mods were the microtech ECU, exhaust, filter and orignal FM I/C
Now for 23kWs from something that I can get for $650(NZD) sounds awesome ay?! I'm wondering if anyone else has had a similar result with one

No read the article again. The power of the ZE motor with the microtech installed but untuned (ie, way too rich) was 77Kw, and after it was properly tuned then it was 100Kw.
Unless your motor is way out of tune, it won't benifit from adjusting the a/f ratio.
What mods do you have? You may be able to get a bit more power out of it with that afc, but not 23Kw. Maybe 2 or 3.

surely it must have had a big pully to get 100kw @wheels ...them SC's aint that efficient and only boost 7psi-8psi ..still $2k+ for 22kw with stock boost is pretty sweet

100kw atw out of a GZE with the SC12 running std boost is a physical impossibility.
several GZE sprinters on this group ran within 3-4kw of each other at the first dyno day a year ago-all got ~100kw atw.
they ALL had oversized pulleys,and were running 11-13psi boost,
and some form of aftermarket management.
don't believe what hot4s writes. for a start,Martin Donnon writes a lot of their tech articles. I won't go into that atm,but suffice it to say that all is not as it is told.
did you read the article about getting over 180kw out of an S15 running the std turbo in High Performance Imports? that is impossible as well,and I can provide dyno sheets of a dozen S15s with similar work to what they had to prove that is also false.
their aim is to sell magazines to teenagers,not be a reliable source of technical data.

I must agree!!!
[whinge]
I am a subscriber to Zoom though in my experience power figures produced by cars on there , especially the "budget" style buildups, are rediculous !!!
all these sr20det's and rb 20's making supposedly over 180 rwkw on near stock boost and an exhaust + cooler !!
They are great engines but the reality bites hard for enthusiasts who try to replicate the results, makes me think that maybe SA dynos read high or something ....
thats rediculous too , but there are serious inconsitencies with hp figures.
both my younger brother (r32) and my flatmate (180sx sr20det) have done similar upgrades to the tech articles with nowhere near the result. their cars run great just not "like in the magazines " !!

yeah u guys are probably right
     i love the icons on this site 
another thing....
A friend of mine got his car dyno tuned. ae101 4agze, mods: 2/1/2 exhaust, filter, 160mm pulley, new cams. The first untuned dyno run was 83.4kW @ the wheels. Then they tuned it, did the timing, put in an adjustable fuel pressure regulator and he got 94.9kWs. But its still not right.
The two sheets looked like two total different cars.
The first run, the power curve shot up to 5500 then dipped down as quickly as it went up! And this is apparently what all dyno runs are like on GZEs.
In the final run (94.9kW) the power curve looked alot better, it was on a steady increase right until redline.
Any ideas of how u get rid of the sudden dip of power in gze's?

I think people are missunderstanding the ZE in the hot4s.
The first figure off 77Kw with an untuned microtech, still had the bigger front mount intercooler and big pod & 'sports exhaust', which would make a big difference, particularily the intercooler on the dyno.
So it's making approx. standard power with all those mods. Of course it's gonna gain 20 or so Kw. You'd be pissed if it were any less.

So say with a turbo setup stock (bluetop) ecu @7psi with gze cooler would 97 kw @wheels be a good sum ?

hi guys, i'm only new here, i have an import 86' AE86 coupe GTV, recently just got a GZE ae92 map sensor 165hp version, as i shattered # 2 pitson in my GE! i put in all in myself, with my TRD hp coated headers, 2.25 " mandrel system, 420x250x60 FMIC, pod filter, and i have put the t-pice in the abv to stop it bleeding above 8psi, it reach 9.44psi max from 4600-fuelcut ran it on the dyno in tuning mode (not shootout mode) and it made 104kw @ the wheels, (139hp, i can post the graph) i was actually expecting a bit more, but from the sounds of things, i should have been expecting less?? whats the go, do i have some freak GZE or does the exhaust 1.5psi more boost, and a good size FMIC make that much of a difference?

The article was called 4 A Great Zesty Engine. I'm sure Hot4s wouldn't mind
