SSV Stuck Open? -- Greddy Turbo
 

Okay, I have a greddy turbo kit along with some extras (accessport etc.) and lately when I let off the gas to idle the car will either die or bounce anywhere from 500 to 1100 rpms while under idle? I ran a code check with the AP and it said the ssv is stuck open? I checked the ssv and everything seemed intact and operating? what do you think the problem could be?

Suggest you try a search on 'hunting idle' and/or 'erratic idle'. You'll find lots of posted inputs on this condition, some involving greddyized motors.:squint:

Can you move the SSV by hand?

Who's calibration are you running on the AccessPORT?

Yeah, I already checked that...I can move the solenoid by hand. Aside from that I reset the ECU and re-installed the AP and there hasnt been a C.E.L. in a couple days, however it still idles rough from time to time.

I'm currently running the Stage 1 calibration that comes with the AP. Is there a way to get a better map?

DO NOT RUN THAT CALIBRATION ON A BOOSTED MOTOR!!!
It is (as explained in the instructions that go along with it) only for stock car's that are normally aspirated.
It is absolutely amazing that you haven't blown your engine to bits.

The only way to get turbo calibrations for the AccessPORT at this time is through me.
Just follow the link in my sig.

This will get interesting...

Indeed.:eyetwitch

Are you still doing that calibration service? :cwm27:

Yes.

...Excellent, when you get some free time and get to my email(s), let me know if you can help me out.

I have a whole batch of calibrations going out tonight.
I am just trying to get some done right now.

Right on,

...And for those that didn't catch it the first time "SSV stuck open?"

Were you aware of this "TSB"?

nice i had not seen that one..

beers :beer:

Thanks, I'll look into that.

and I dont see how Im gonna blow up my engine with a air fuel ratio from 14 to 20

:eek::eek::eek:

In boost,your AFR should be absolutely no leaner than 12.5:1 !!!!!

You should shoot for 11.9:1 up to 12.3:1 where maximum power is.

wow, unbelievable... :eek:

in case you don't know: higher numbers AFR = LEANER. lower number AFR = RICHER

like MM said, your WAY to lean. somehow you haven't destroyed it yet, but if you keep driving it like that it wont last long. Most people shoot for a lower AFR than MM mentioned just for safety net so they dont pop the motor... like 11.5 or so. (then there are those like Kane around 10.5 hehe)

14 to 20 ? ... thx gg gl hf.

lol

this made me laugh.


sometimes ignorance is bliss. If he knew better, he'd be shitting his pants.

I want to see him try it. MAYBE IT WILL WORK !!!!! :lol:

could you blow it up and get it over with..

anyone what to start a when it goes pool?

beers :beer:

the access ports un-installed...and thanks for all the ignorrant replies guys! you really helped!

Ignorant replies?

I'm sure some seemed harsh, but I don't think you understand the magnitude of your lack of understanding of the subject.
Uninstalling the AccessPORT is not going to fix the problem. You can't run a turbo without proper engine management.
If you use the AccessPORT, you MUST have a calibration that is setup for forced induction.
If you don't use the AccessPORT, you must have some other form of fuel and ignition control. It is NOT an option.

om.......fg 14-20?!!?? you sir, are the luckiest SOB alive, not blown your engine yet with 14-20 AFR ration is like winning the lottery

hell, I'd be scared if mine was @ 12.......
