Failed Inspection with a tune...
 

Hey everyone, curious to know if anyone might have some ideas why a tune would prevent an NYS inspection machine from reading my ECU. I'm using an OFT Stage 2 93 EL tune. My OBD reader works just fine, green readiness monitors according to torque, the inspection machine says its connected but fails to talk with the ECU.

Has anyone come across this? I flashed with a tactrix cable but I can't imagien that woudl matter much. I can still connect and read my ECU just fine. Just trying to prevent myself from having to pull off my header and flash the stock tune due to a CEL coming on at somepoint.

I also just read something about NYS having new machines as of last year which has been causing problems for people with tunes on other platforms with the failure to communicate.

If any readiness monitors are turned off it will give a failure to communicate error..

Anyone know what readiness monitors are turned off in the oft tunes?

The tuning forum or OFT directly would probably get you an answer. http://www.ft86club.com/forums/forumdisplay.php?f=88

Your tune probably disables that O2 sensor after the cat (where the cat used to be), sounds like this would fail it.

You guys should move to Maine, they shine a flashlight around the stuff that matters (having enough brake pad, tire tread, suspension holding together ok, horn and wipers working, etc).

I’ve passed with Longtube Headers and no Cats on an LS1 car, they didn’t care, as long as the car was safe otherwise.

Having said that, in this day and age all cars on the street should have Cats, its a no-brainer and there are performance options, which do quite well. I don't condone deleting cats altogether, but to get rid of one which kills performance and put something in its place, is ok in my book. Driving a backroad is so fun because of the trees and rivers, keep it clean.

I have the OFT tune that probably does that, since I have an uncatted header, but I passed my NY inspection 3 weeks ago.

I see nothing in romraider regarding disabled 02 sensors or anything of the sort


I see a lot of disabled DTC codes however I was under the impression those are not the issue when ti comes to readiness monitors.. However maybe I am incorrect in that.

Out of curiosity, could you PM me the tune file your using so I can look at a few things?

In Michigan they don't even do that. Bring a title + proof of insurance to the Secretary of State, pay for registration, leave with a new license plate (or new tabs). No one looks at your vehicle here. Ever. I haven't had a cat on any of my cars since 1996.

If you hand build a car here (like a tube chassis car from scratch, no VIN), someone from SoS will come out to your location to check it for: headlights/taillights/blinkers/windshield wiper/windshield wiper squirter, and a 2-point seatbelt. As long as you have that, they slap a constructors VIN on your chassis and assign a constructors title for it. 1 manual wiper with a sporting goods water bottle will pass!

OP - Sorry to hear.

Looking at TM's tune for the ESC the only difference is he has is MAP code turned off.

Maybe I'll try a different inspection station.

Well I went to another shop. It failed twice but on the 3rd attempt went through. So looks like its not the tune. I have tried two obd2 adapters and my tactrix all work without issue. Weird. So for anyone wondering yes you can pass NYS inspection successfully with an oft tune

We don't have inspections at all in South Dakota, but don't move here. Ever.

Same thing with oklahoma

Well Scott, its tough to beat that.

No inspections in FL at all, ever... Yes, move here :D

Before everyone starts jerking themselves off that they don't need an inspection in their own state.

I'm confused as if you flashed back to stock tune or not. Or is your headless catless, thus causing an immediate CEL?

Yes, and I have seen the results of that fine system driving down the road (or attempting too) way too often. Missing bumper covers, loose dangling lights and mirrors, clouds of black smoke, cardboard windows, completely bald tires, rusty smashed in body panels and just about any other nasty thing you can imagine are far too common. I have personally been hit by parts flying off cars in the Detroit area on three occasions. One particularly bad Neon flung it's whole tail light assembly into the air and hit the top of my bumper (there was a car between us).
There certainly is something to be said for a decent inspection system.

I'm running a catless header

I did not flash back to stock. I simply went to another station after someone in this thread mentioned being in NYS and having just passed an inspection. Comparing the tunes of his and mine (aside from fueling as his was a FI tune) all the diagnostic stuff was the same.

I figured I'd try another shop. I'm guessing the OBDII scanner they use is a little worn down for how much it gets used and just makes a crappy connection with my port. All my OBDII devices work just fine. It failed 2 attempts and the 3rd one finally went thru.

Multiple forums for various other platforms were commenting the same "Connection Failure" issue with a tune on their car which is what prompted me to make this thread. Even though the OBDII device says its connected per the diagnostic light, apparently some tunes will cause a "Connection Failure" message with NYS machines if any readiness monitors are turned off. However it does not appear Shiv disables any of those things in his tunes. The disabled DTC codes have no effect on this.

Understood.

Did they put the sniffer on your exhaust?

NYS does not require SMOG. However If I recall some places in NYC do dont they? Either way I'm upstate
