I'm not sure what you guys are referring to as plug and play.

If you are not tuned for a 90mm and 42's, then it won't run, or shouldn't.

i meant the wiring/connectors were plug n play. basically you connect them and go.

I thought that was what you meant, but thought that clarification might not hurt.

I notice that your question about a wideband has not been answered. With boss's new set up, I would hope he has one.

even if he was borrowing one for the initial stages it would benefit him... but then i know the pocket book, it might bitch, mine did.

i dont have one yet..i do know that i need one..i plan on getting it tuned on a dyno after about 500-1000 miles though..hopefully i will have one by then.. i do have a walbro 255 pump..if that makes a difference with not having bigger injectors..

Klitch · #**126** 07-14-2008, 02:29 PM

you have a fp gauge? even a mech one to just see what your fp is at idle and off idle. you have 20 - 15" vac?

boss1984 · #**127** 07-14-2008, 02:49 PM

i dont have a fuel pressure guage..but my vacuum is right at 20-21 at idle so i dont think i have any disconnected lines ne where..im hopin its just the timing and the bigger injectors..

boss1984 · #**128** 07-15-2008, 07:23 PM

i just ordered my 42lb injectors and a 90mm maf..so hopefully it'll run better when i get them on in a few days

I just dont see that helping... has to be tuning problems. at idle, its not needing more fuel... injectors only give as much fuel as needed, but maybe the tune for the 42's will be correct.

boss1984 · #**130** 07-15-2008, 07:36 PM

see thats the thing..it idles ok for the most part so i know that it has something to do with the tuning as well, but even if i get just 1/2 throttle or a little less i can feel it bog down..thats why im thinking that its the injectors and tuning (timing)

boss1984 · #**131** 07-15-2008, 07:39 PM

built, when u asked to watch my timing on the programmer were you refering to spark advance? if so do you know what it should be about? or could you clarify what you mean...

Klitch · #**132** 07-16-2008, 04:32 AM

timing = spark advance on livelink. ive seen mine up around 30 at times.

I agree. You can't expect to bolt on all of this and not have tuning issues. The pcm is going wtf. The O2's may keep it idling OK, but the open loop calibration can't be even close.
