Ditto on this. I'd like to run around 11:1 on a stocker bigport ecu  and probably 256s. Might need some bigger injectors?

Very badly meaning your car would be faster in most applications with the standard cams..
I have the following setup on the standard computer: 100kw block, overbore, shaved and ported bigport head, HKS 256 8.1mm (I think) cams.
The powerband this makes is very good, but the idle is farked. For this reason I would not recommmend any bigger cams unless you use an aftermarket ECU.

I have the 272's with standard ECU as per previous threads. idle is fine, runs fine, but power band is too high for the street and fuelling a problem. You wouldn't put big cams on a carbied car without changing the carb(s).

Sorry, off the top of my head it is 8mm, whatever the standard wade lift for that duration is. Shall have a look when I get home.

Had a look at the wade spec sheet. I have the 872A's which were the lowest duration they had way back when. They are 267.5 degree duration @ ramp (not 272). Lift at valve is 0.317 thou or approx 7.925 mm (I think we can call that 8mm).

In addition, that is with standard shim under buckets and valve springs.

parrot i had the same cams in my 16v too. ran like a bitch. then i got adj. cam gears and it smoothen it out. had an SAFC on hte car as well. SAFC didnt really need to be tuned much anyway apart frm idle. stock ecu made the car idle rich on those cams. it was -24% on the SAFC at idle and i think it was still running a little on the rich side

anything else non standard about your engine with the safc and cams? Who tuned the safc? And if 'you' what were you measuring a/f with?
Cheers

tecnik tuning in fully sik preston. had cams, adj. cam gears and safc on it. i was trying to sell that set of mods a month ago but nobody wanted the whole thing 
now im stuck with an SAFC. anybody want to buy an safc? 
a/f ratio was measured with a stick up the exhaust on the car at dyno place. thats all i know.
try looking up bill sherwood's site. lots of info there. i have a friend running 272 degree on stock ecu and it was fine. i guess some 4age's came with better ecu than others.

Good point. Have always had adj cam gears on it so no problem there. Also have a UK loom with an idle mixture adjustment doover as standard (CO2 adj switch) so that helps too. Currently on the look out for an f con piggyback.

its possible the JDM ecu handles the cams better than the AUDM ecu because of the preset maps.
could explain some working better than others
then again, the base timing and also possibility of cam tming could have something to do with the idle smoothness

Sorry, not having much luck with the forums today.
I've got a JDM ECU in mine for what it's worth. The CO2 adjustment really helps with idle. Should be easy enough to wire one in to the VAF input of the ECU if you can locate one. I can give you the detailed wiring diagram for it if anyone interested.

Can I ask how you have found the SAFC? I have some slightly larger (225cc) injectors and am keen to try a piggyback fuel computer. Don't want to go full management. As above, have been on the look out for a HKS F-con. Car has been off the road for a few years and have been accumulating parts for a refurbishment.

actually as far as we learned (me and toyota parts dude) the injected 4a's all have the same small port head albeit, different injectors and timing...
again i cant guarantee this info is completely correct, as most of the stuff is now fifteen years old and they don't carry alot of it, if any, any more...

It sounds like you are trying to say that a 4AGE and a 4AFE have the same smallport head.
No matter how small your penis is, the Stock ECU will NOT compensate.
