what do i do from here on?
My set up is in my sig.
When i drive hard, my wideband tells me that im at 10.. then to 11.. then 12 point something.My truboost is set at 6psi.. sometimes hits 7 and 8. Granted, i still have a cat... What fmu ratio disc can i use to give my car more power? AND, when i drive hard and pop out of gear so i can come to a rolling stop, my RPMS drop fast and sometimes my car dies. What could be causing this? i do have a 7lb fidanza flywheel if that makes any difference. THANKS IN ADVANCE! |

Usually that happenes at around 75 PSI. Get a high pressure pump, and like a 6 to 1 disc. That will give you about 90 PSI fuel presure, which would allow about 7-8 psi boost. |
Install that fuel pump already! :)
|
if you install a 190HP pump and don't swap out a smaller vortec disc, expect > 10:1.
flywheel causes the sudden rpm drops, you can try to tune it out with your idle screw, however, that's one of reasons I got rid of mine. |
12:1 AFR is great, your tip in accel fuel is too rich at 10:1 AFR. Adding a bigger fuel pump isn't going to improve that, you should consider moving to a more precise method of tuning, ie standalone or programmable ecu.
|
you're probably stalling because of your BOV.
|
ok.. so i have 3 suggestions.
1) i didnt adjust my afm for my 1.8 injectors 2) my flywheel 3) My blow off valve how would i adjust my afm for my injectors? ive noticed dips in my rpm when i was na after i installed the flywheel... but it never killed my car like it does now and how can my bov cause my car to die? THANKS! |
The bov might be leaking air under heavy vacuum causing the engine to suck in unmetered air. You might be able to tighten/loosen up your IAC valve to make it respond differently when coming to a stop.
You can adjust the clock spring a few clicks to adjust for the 1.8s. Do a search, this procedure is well documented on the forum. Though i don't have a link. |
For teh record, I have the 7lb flywheel and I havent had problems with it, works great!

I've had a bad idle dip problem that I solved by doing a boost leak test and fixing all the leaks. The flywheel will cause your idle to drop more than usual.

So your saying i should get a lighter flywheel?
|
lol, it does pretty much stall already, no clue why...its pissing me off though.:crx:
|
Try setting your base idle to something like 1000 rpms. Mine is set to 950 and I don't have a lightened flywheel, although I just now bolted the Fidanza on :)
|
ya but it idles good when its just idling but when i turn on the lights the idle just drops:eek4: battery?
|
ive been searching and i found some threads about setting my idle?
its says to jump the ground and ten in the diagnostic box. does anyone have anymore input on this? thanks! |
I would suspect the IAC if your idle drops when you turn on the lights. It's actually supposed go up a little bit.
On the drivers side of the engine bay near the top of the shock there is a little black box. That is the diag box. Jump the terminals with a bent up paperclip. |
