Hmm.. AutoZone has a rental fuel system gauge...

I'm basing everything on my wideband numbers... I wideband i suspect has issues.. I've decided to stop troubleshooting until i install a new sensor.. Already in the mail
However, i will clean up my ECU grounding and pull a spark plug to see how they look this afternoon

 

UPDATE: with car idling i grounded each secondary injector at ECU... Front and rear both bogged engine down and killed it = they are working and i have already confirmed secondary injectors are getting signal while running (earlier post)...

Fuel pressure has been checked... According to gauge, at idle its sitting at 50-52 psi (i assume this may not be accurate, but i was checking for PRESSURE DROP)... Under load (no boost) it drops to 42-44 psi and raises up and HOLDS 52-ish psi at 8-9 psi boost. AFRs hit mid-12s under WOT... For the skeptics out there, here's proof: (at beginning of video, the needle is pointed at 50-52psi.. For referance) http://www.youtube.com/watch?v=mjd82...e_gdata_player

So... All i got is either my wideband is **** (new sensor in mail), i need larger injectors and/or time for stage 2 RTEK

... Yup

 

New wideband sensor installed and actually preheats!!!
.. But, still lean on WOT. *Its mid-11s up to WOT though.
... While i MAY not be maxing my current injectors i don't see why installing larger secondaries couldn't fix my situation >*http://www.injectordynamics.com/ID1000.html

 

You may want to have your injectors flow tested. I've heard horror stories about rc injectors not being anywhere near what they are supposed to be.

 

I'm getting more hits on my thread i started in the 2nd gen section... Here's the thread..
