Well, got the downpipe on today along with the 550's.. seems to run good, I used RRE's sample AFC settings for 17 psi, despite not having a fmic.. This, because i have yet to be able to tune the beast.
http://www.roadraceengineering.com/newafcsetting.htm First off, the good news, she sounds PISSED! I mean this is a serious change over just the catback and stock turbo, deeper and badder then ever! Second, the bad news.. 1. There's some major dying off happening at about 5k in every gear, its as though the car is going to take off from the ground and then all of a sudden falls on its face, my thought was that it was a vaccum leak but iv checked everywhere and the car was running fine before i put the dp and injectors in, then possibly its an exhaust leak? Could be likely, seeing as the gasket between the dp and o2 housing was shit when i put it back on, but im not sure that would cause this affect? would it? The only other thing i could think it would be is the computer detecting way to much knock and just cutting fuel or somthing? That damn datalogger is next on the freaking list. 2. Like i stated earlier, I ran a line from the wastegate directly to the turbo to maintain minimum boost levels while the car is untuned and without an upgrade i/c... well somehow I'm running 16 psi in 4th now. I was running only 12 earlier but it would spike too 15. Now it goes straight to 16 and drops steadily until it starts f'ing up, maybe thats the stock boost level on the super16, i have no clue.. ill have to look into that. Anyways, any thoughts on whats up with the car just falling on its face would be much appreciated, i wanna get this bitch moving! -------------------- 1997 Mitsubishi Eclipse GSX

QUOTE (Rollout @ Jun 20 2004, 07:11 PM) Apprectiate it guys, 450s are back in and the car is running fine, actually it was igniting yesterday at about 6k rpms since i had the AFC turned up... I cant believe it was running rich.. so i just put all the afc setting back at 0 good call there. Leave it at 0 with your stock injectors in until you have some way to see what's going on. I tuned mine by O2s back in the day. I'm just lucky I didn't blow anything up. Also I'd like to welcome you to the freeflowing exhaust club. Boost creap comes with the territory. -------------------- GVR4 866/1000 = the perpetually broken car
