idle issue...again
Okay so i got it idle at 900. I drove it around the block and it was perfect. than i drove it to the shop for the ebrake to be fixed and whenever i had the clutch in or in neutral, the car idle erratically. It would bounce between 1 and 2k. Any ideas on a fix?
|
using DIY's settings for the idle valve?
was it in warmup mode and before and now it's not? lots of variables....could easily be the VE table. |
it wasnt in warmup when i drove aroud the block or when i was tuning, it wasnt either when i drove to the shop.
|
hehehe...i'm having the same problem...
|
sounds like the idle valve is messed up dude, adjust it and make sure you don't have to much timming retard down low etc.
|
i've got 17deg at idle. i'll check the idle valve, link to instructions?
|
so what does the timing and fuel do with idle speed? I assume less fuel and less time = lower rpm?

I found more timing means a higher idle, and less fuel (to a degree) also leads to a higher idle, (but less smooth). it's all a compromise, find the best setup for yourself and stick with it. Personally I'd set the idle to 10 - 12 deg and go from there. |
Just put the MS at a stable 10 or 17 btdc to lock it in then adjust the screw up or down until the idle is what you want. from there you could ask jerry or some one who knows the code to loook atr your controll software if that does not fix the problem.

okay, well i lowered my spark to 10 deg and went into the idle setting than put all thec cells around my idle to the same, and set it to warmup only. It is now settled at 900 which i like, and all is good. my question is this, by setting it to warmup only what are the effects? What happens now that i set it like that?

bumpy bump

ah you where dumping to much fuel becouse of the AE on idle huh. Yeah that would do it to. The settings you have mean that it will only tryt o stabilize idle when in warm up otherwise the mechanical TB and VE map should keep the idle fairly stable, I am glad you got this right. How does it run with a laod on it now at idle lights AC etc?

If it's stable in warm up mode, that means things should be set up close to right. I'd turn the warmup off again, and play with the idle valve settings, oscillations often mean things are "too tight" or "too fast" so make a bigger window about the idle you want and see if it helps? There's a lot in the manual on setting this up it's probably a good place to start - they might have suggestions for good numbers for you.
|
thanks for all the help. I will attempt to get it right, after i do my emissions. I want to keep a stable idle for that. Im fine with the idle dropping with AC, i dont use it much.
