won't disabling the 02 readiness test mess with the emissions test

I set the enable temps to 300 under closed loop enable temp

I am unable to turn closed loop off via the tune for some reason, i can manual do it in the VCM scanner but when i turn it off in the tune it still comes on in the status bit indicator. all it seams...

Without being able to actually see the tune right now i would say look at the injector flow rate table and make sure it has the proper values in it.

Thanks for the help guys

I can kind of see how it might be the long tubes but at the same time i shouldn't have that big of a difference in readings, the wideband is only like 15"-18" behind the narowband with nothing but...

So i dont have access to the tune file right now on this computer so i am not able to post it yet. Maby some one has seen this or knows whats going on of the top of there head.

Nope, look at post #8. I would bet as soon as you do that it will cure your problem

set them to 1 and un check the SES box

Ben if you have those set to no error reported then your car is not in SD mode they have to fail in order for the car to revert to SD mode

Ok here is the best example that i can provide. In the first log "idle at operating temp" Look at the afr. Then look at the second log "Idle at operating temp with ve change" in this on it has the...

I have never had a problem with this befor either. My question regarding the
P0101 was does that dtc have to set in order for the car so fail the maf and go in to SD or will it fail with P0102 and...

So i have the custom 2bar OS and i am having a hell of a time trying to tune the afr from the ve table. Any change i make to the ve table does nothing to the afr. It stays at 12.9. When i first start...

The tune that i first posted was one that i used for one run in trial and error it is not the final tune that is being used nor was it ever used more than once. I have updated the tune in the first...

yea its definitely not wheel spin and its not running meth. I have pulled all the plugs checked the gap all were fine. The thing thats getting me is that its so consistent when it happens, run after...

here is a picture of the dyno run. the green line at the bottom is the boost. Red is HP blue is TQ. I'm sorry for the poor pic having some computer problems

there is a very noticeable change in the exhaust tone. it almost sounds like when you hit the rev limiter but that's not what it is because the car keeps pulling. Did yours have the same sound

I will post a graph as soon as i get on that computer. The afr and timing in that log are not what it is set to, i have the afr at 11.5, and timing at 15 wot. That log file was just one that i had...

We just put a procharger and cam on a 2011 corvette Grandsport. Everything in the tune is fine except when we are trying to dyno it. It pulls great until we get to like 4800 rmp it then just drops...

it was write calibration, but not on a 2bar OS.

I Just re wrote a pcm in a 98 c5. This is a re-tune because i just put a blower on it but i have written this computer many times prior to today with no problems. I Just wrote the new tune in the...

Here is a better example. The first tune it is rich by 11%, seen in the first log. I change the ve by 11% in the second tune. In the second Log again still no change, Fat by 11%

I have tried just about everything and am in need of help. The AFR is not reacting to any changes I am making in my VE table while trying to dial everything in. When i first start the car and let it...

Chris, I just did that but it is still polling the Lo Res and giving me the same results. I tried moving all of the .os files to a different file just to try that and it didnt help at all. Any other...

I don't have a High-res AFR pid to choose
