VS L67 A2A closed/open loop problems

[VX L67 Getrag]

Yeah they should match so long as it's not in closed loop, which is what I can't get it out of in idle areas but 16:1 is what I want there as that is where it's STRONGEST!

As far as PE no it's set at 12.2 once all the modifiers come in & bang on target!

turn closed loop temperature right up its on at 30 degrees right now and set at 14.7 closed loop idle is set on between 1.95 and 3.13 tps and 10-11 g/s airflow

Thanks for those pointers it should meet all the criteria for those other things you mentioned except I only just noticed now you mention it the is a low hysteresis of 10 G/s & hi hysteresis of 11 G/s, so does that mean it has to be in between those values for closed loop idle to work?
Seems a small target for factory setting & will need to look at the setup to see whether that is for closed loop IAC or closed loop fuel as it may well be the answer for 1 of the flags not being enabled.

EDIT; just saw the TPS 1 you mentioned too so again I guess it must be in between these values for it to go in to closed loop idle, so if I set it for 0% tps to 5% & the G/s for 0 G/s to 15 G/s it should force closed loop idle.

With the closed loop fueling I'm not sure what you mean there as it's already over 30deg & the closed loop ratio is set at 14.76:1?

just keep in mind if you lie, trick or cheat the ecu in just one setting it can throw thousands of things out of whack

LMAO, sounds like your talking from experience, would there be something in particular you mean with what I said about adjusting?

Well the next test with bin & xdl's attached, I set the not select for closed loop idle flag as the way I read it means if it's set it will set closed loop idle to work? but other thing I changed except for pre mentioned hysteresis was the timeout for closed loop to open loop p/n as I made it max to try & always stay in closed loop but still no luck!

The first log it stalled coming up to first stop, which is why I want to force the air fuel ratio & iac to try & catch this when it happens some times.

The 2nd log it did keep running up to intersections but you can see the closed loop idle flag is in-active most of the time & it's stuck in closed loop fuelling, a bit before the end where it was parked teh IAC flag became enabled & IAC started working but then right at the end I went to park & it became in-active & IAC steps went to zero & it was below the desired rpm?

you need to tune the closed loop fueling first so it will cruise along properly and maybe an o2 sensor or 2 one sides correcting for rich one sides correcting for lean.get it so closed loop works as it should first then worry about commanding the 16:1 you want looks like the ecu is packing a mental with stft's heading both ways opposite each other

[delcowizzid]

or there is a mechanical issues youre trying to tune round weather it be an injector bad blower porting/air distrobution a dead cat dead o2 or o2 leads swapped side to side somehow.is it twin to single exhaust and you tuning with the widband up the bum measuring both banks as one and you tuning to 16:1 is leaning out one side thats grossly rich being why 16:1 is the strongest

[delcowizzid]

do a search in google split blm tuning.it can happen on N/A engines from simply having the TB to far open so im guessing a big open air to air plate doesnt help LOL

Thanks for all that DW, yeah I have everything as close as I can to make the car try & keep running as best I can & I have noticed the o2 sensors & have tried swapping & replacing sensors but doing the best I can with the mod's it's got!

Hence why I'm just trying to get the 2 modes active & then I know what will & wont work!
