4 throtle for VTEC engine-TWS from US.

So how is the powerband like , more towards topend or midrange ?

topend power. overtaking can be very sluggish sometimes but when full throttle from idle the power just burst.

Hard to comment cause i didnt see your unit:X-: ,,,if you have the spec, you can PM me. I need your butterfly size, the overall length (intake manifold+butterfly+trumpets), manifold runner size & trumpets size. Photos will be fine too.

morning zaki
if safc/vafc would work fine on quad tuning, i reckoned there will be more street quads users both honda and mitsubishi enthusiats, branded or DIY, by all means.

i personally ran quads with safc to work and back daily. i even adviced leftfoot(the dude doing quads project in car mods section) about my previous setup. i honestly say quads is the way to go for me. i know its a very subjective matter when it comes to quads vs big plenums, but i chose to run on quads last time. no doubt safc can barely run, but finer tuning is not there. its just not there.

if its on a honda, i would run apexi power fc or hondata since malaysia has both strong background for both ems. lets not compare with americans whereby they have neptune and chrome or australians with the motec and microtech.

safc doesnt come with base maps for map and tps tuning. very hard to tune low throttle, medium throttle, partial throttle and full throttle.

i believe we have a handful, maybe two hands of quad owners that is living healthly is klang valley but not running them to giant or jusco supermarket due to no-aircon, too loud for police roadblocks and for "night" use only. there is another daily driven quad throttle owner with airconditioned to work which is reading this post and he knows safc is just not sufficient.

i might run again this year if they stop hiking the fuel price but with ems this time, no doubt. so the best advice from me is if you can afford like toda or twm with hondata, its all good to go. ems is the main thing, the quads are secondary issues.

the response is something spectacular when it comes to quads, i believe v8nutter knows this very well too.

cheers and have a good day.

J101,
Very well said,bravo...ha ha ha.....If piggyback will be tat sufficient then all those apex'i power fc, motec, haltech, microtech, hondata don have to sell their product so expensive n keep on coming out v new model, might as well stick to safc.....ha ha ha

Cheers

j101,

so how did urs work with just safc?

but the potential is not fully used?

 

[J101]

it would definitely be better with an ems, u have an
upperhand on all requirements on the basemap itself
directly.

if its a weekend fun track/drag car it might be just enough with an safc
to fool around as u just have to full throttle it without having so much
problem with all rpm ranges tuning both fuel, ignition, map and tps at
all rpm speed ranges in combination.

cheers

J101, saw your setup, try to lengthen your intake by 1 more inch, it should get back your mid RPM. Not the trumpet but the intake runner lengthen.
