Hey guys. Okay, most of my build was posted on (another site), but its obviously gone so i'll do a short recap.

Had greddy tt kit bc malfunction caused overboost and i broke my piston ring lands. blah blah blah. Anyway, its a 2006 rev up. I pulled the engine, had it bored/honed/balanced/etc. I built the engine
CP 8.5:1 cr pistions .5mm over, carrillo rods, arp L19's, hks head gaskets, open dumps, etc etc etc.

I started the engine with the stock fuel system and 440cc injectors. map i had on the utec was perfect. First start up was flawless. Only thing is my SEL, VDC, and SLIP lights are on. OBDII says crank position sensor. Makes sense. I've cleaned it off, checked all grounds, everything is good. They won't go away. Only other thing i can think of is the JWT flywheel. I dont feel like pulling the flywheel back off so any suggestions would be appriciated. My next step is changing the sensor out.
Next issue. I got my fuel system in, AAM stage 1 and rc 750cc injectors, and walbro 255. well they sent be a gss341 instead of a 342 so i'm still running the stock fp till my new one comes in. I set the fuel pressure at 42 psi w/o vacuum, which puts me at about 35psi idle. pressure is going up with boost as it should. The car is running rich as hell! Idle is about 13.8 and as soon as boost hits and utec switches to map wideband pegs out at 10. Also, the rev up (not sure if regular DE's do this too) cuts the injectors on decel showing up lean on the wideband. Has always done this. Now with the 750's it goes rich, about 11.2-11.5 on decel. I tried 2 different maps and parameters on the utec for 750cc injectors including the one on the txs website. They both run crazy rich. I lowered the pressure that the utec switches to map to 0 which helped a bit but not much. I don't want to mess with the maps too much yet till i figure out exactly why it is so rich. By the way i'm just running boost off the wastegates right now, about 5.5psi, for break in. i've got 800 miles on the block. Not gonna boost more till 1000 miles when i change the oil again.

so, if anyone has any suggestions on the lights or has a better map or suggestions with the fuel system, any help would be appriciated. Sorry for writing a novel.

most of my build is on youtube if you want to see. http://www.youtube.com/watch?v=-e9kcBvsPYc

edit: forgot to add that my tachometer is jumpy. I can move the sensor around and it stabilizes but the lights are still on.

 

Have you tried a new crank sensor? We keep them in stock because unfortunately they do fail.

 

i'm going to get one this week. i hope that solves it. Just odd how it happened right when i put the engine back in.

Has anyone else had problems with the txs 750cc base map?
