dexter72 Posted March 17, 2011 Share Posted March 17, 2011 I think you should start saving up for an EMS setup and wideband. The components look good but can you even tune it?. Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted March 17, 2011 Share Posted March 17, 2011 my ford e150 van with 5.8 has 19lb/hr injectors. the injectors have orange color code on them.i think the original 280zxt injectors were 24lb/hr.if you keep running this thing up till it leans out you risk major motor.damage.the my z has 44lb injectors with a vipec ecm.there is no easy way to change out the efi system-i ripped out all old zxt stuff and started over with new connectors and built my own harness.used to rum megsquirt but it seemed like i was always chasing problems with that.but that is just my opinion on ms-your results may vary.all of the guys on this website that have a running high horspower l28 turbo hava had to learn alot about efi systems to make the hp Quote Link to comment Share on other sites More sharing options...
NicksT04=S30 Posted March 18, 2011 Author Share Posted March 18, 2011 yeah i belive they are 19lb injectors but mine are yellow top, like i said its what i had to use but i can tell you it still runs rich Ive bumped my fuel pressure up to 50psi and it also raises with boost pressures,so with boost 65 psi on the injectors which may be to much but ive never hit detonation on it yet but im keeping an eye on it, as for my system i can tune everything on my ignition its has twin rev limiters,rpm windows,boost to retard deg i can set it from 0 deg to 14 deg retard per pound or boost and its messured through a 3BAR MAP sensor its a CD setup, hey randy77zt what MS were you running before you went to viper, 1 2 or 3? and how easy was it to setup the viper system cause ive heard alot of people curse MS installation Quote Link to comment Share on other sites More sharing options...
