20G, 720cc, S-AFC will it work?

[Peter's Eclipse]

i have a 99 GSX, i'm planing to get a 20G turbo. right now i have s-afc for tuning and 720cc injectors, fmic, and etc. will the s-afc be able to tune and get the car running right until i get dsmlink? what do you guys suggest i should do/change, to my current setup? e.i. turbo, injectors. any help is greatly appreciated....

the biggest injectors a safc will compensate for is about 660. You could get away with the 720's, but you will be running very rich. I would hold off intalling the injectors until you can get dsmlink

The Safc will be no problem to you. It will make it much easier if you had a Wideband to tune with though. And of course, tuning will become so much easier with Dsmlink and a Wideband.

Tom04841, we idled 780's with a Safc and have had no problems out of it. But like you said, would be much smoother if you already had Dsmlink.

 

[tom04841]

you idled 780, but what were your trims? You had to be running rich. The 780 flow about 70% more than stock...the safc 1 can only compensate +/-30% and the safc 2 can go +/- 50%. I have no doubt it will idle, but ou are going to be running crazy rich

so do you guys think i should go and get some 660's?

Ah, wasnt paying attention. We didnt use a safc 1, it was an safc 2.

 

[tom04841]

all depends on what your goals are. If you have the 720's keep them and if you have an eprom ecu get a custom chip to compensate for the until you get dsmlink. You will be able to idle the 720's, but you WILL be running rich. You will lose a little fuel economy, but your putting on a 20g......i don't think you really care...

You should be fine, i was just trying to make an accurate statement, not what can be done.

running 720's with a afc2 here. i get 18* timing advance @ redline. tunning wasnt too hard but you be much better off with a dsmlink setup. im in the process of getting dsmlink, but you will still make a heafty amount of power just tuning with the safc alone. Get dsmlink and a wideband. youll love your car after its fully tuned.
