Emissions Readiness

Downloaded the Torque app to check for readiness before bringing the car in to get inspected here in MA.


I changed the battery and when I did the O2 readiness became incomplete, so I can probably get that back to complete after a few drive cycles. But I checked readiness before replacing the battery and even after driving the car every day for a week the other 2 were still reading incomplete. (catalyst and O2 Heater) I had read on other forums that these 2 on could actually be tied to a dead battery, and the red top I replaced is certainly toast. Replaced with a Shorai.
Car has a Rev400 kit with PPE header and CAT. I bought the car used from someone who knows nothing about it, so I'm still figuring out this particular car.

I've never been able to find an OEM drive cycle from the service manual for our cars. However, during your tune they have disabled your evap and possibly the readiness of the other ones to prevent a MIL from coming on. How many miles have you driven it? Try to reset the ECU and drive it again.. it could be frozen. Drive it 30-50 miles and see if it complete it. If it doesnt complete a single one you may need an ECU reflash..

Pretty much what I expected. So I just put the new battery in the car, will drive it a few more days with a mix of highway and back road driving.
I found the toyota drive cycles: http://www.watrd.com/work/TSB_EG003-...revised%29.pdf
But internet legend is that lotus' might be different.

BOE did the tuning back in 2013, so I don't think they will know what's been turned off. It didn't sound like they were able to do email tunes any more, I think you need to send in the PCM now for re-tunes.

Have you tried, you know, calling and asking Andrew about the tune? I know for a fact that BOE still has the records on this car.

I was hoping I was just missing a simple fix, before bothering them again. Again, learning the idiosyncrasies of this platform.
Like I said I found the Toyota drive cyles, but have yet to hear anyone confirm the Lotus ones are different.

But I already PM'd Phil twice both on this and the cost of re-tunes. I'll just end up calling tomorrow if the Toyota drive cycles don't work

I'm traveling till next week with minimal email, etc...

Only saw the 1 PM, so not sure about the twice action you mentioned there.

Prices for tunes are generally on the BOE site at 850 or so for the Elige. Happy to help...

Won't be back at shop till next week so it will need to wait till I'm caught up and back.

thx,

Phil

I had the same problem when I bought my REV300 Elise. The original owner lived in a state that didn't require emissions (as did the 2nd owner). So, BOE turned those flags off on the ECU, to avoid the check engine light. However, I live in VA, where they DO require emissions. Had to have the ECU pulled, sent to BOE, and reflashed with the flags enabled. Got it through emissions (and the check engine light came on literally on the drive home from the emissions station).

Well if there's a light on, I can deal with that. A buddy is doing the inspection, but I can't have anything get picked up by the OBD2 scan.
He said in MA just make sure readiness is ready to go and on certain cars the machine pulls the vin from the PCM as well.

The last 2 owners both came from San Antonio, TX, Not sure if they have OBD2 testing there, but the guy went through the trouble of putting a cat on the car so I was hoping it was set up for emissions.

My recollection is that O2 sensor heater should set immediately on startup. Please check the appropriate fuse in the engine bay: Fuse 5?

I have provided a working drive cycle for the catalyst here on LT. Note that the catalyst will not even try to run until the O2 sensor test has passed.

I checked all of the fuses a while back trying to figure out why the radio wasn't working, but doesn't hurt to take a second look.

Just drove the car today about 25 mins and the O2 is ready again, just as I thought. Leaving the 02 heater and catalyst still incomplete.

I'm assuming you're referring to this drive cycle: https://www.lotustalk.com/forums/f259...-cycle-392394/

If so I can do that on the way home from work. If I don't run into traffic.

I had issues also and posted somewhere on LT also. Have to let the car idle for 10 minutes from cold start before you drive, go on freeway don't go over 60 and very light throttle inputs, low rpms. IIRC, after the 10 min idle EVAP and O2 were set. CAT is the one that requires some driving

Went through the driving cycles today, O2 become ready as I thought. Other two, not so much.

Driving under 60, especially seeing as my speedo is about 10 mph off at that speed deff pissed some people off. Lol I can tell with 100% certainty that I got passed way more in that 20 minute session than I did all last year, maybe the last 5 years.

Does the car even have an evap system? Removing it is often part if the rev400 install

Not likely, as it has an aftermarket fuel tank with baffling I believe. I saw it on the invoice, but I'd have to look it up again.
But Evap isn't coming up as an issue.

Emailed BOE, and sent them the invoice and VIN. Hopefully they can look it up.

LOL I stayed in the slow lane and was even thinking about taping a sign to the back "SMOG TESTING".

That is not necessary for the testing. I drive up to 75 mph, you just want to avoid diving deep into the throttle (hard acceleration).

I had a bad Odyssey battery (will never buy another) and didn't drive the car for a while so I just did the test Sunday. Now I'm getting a P0171, but it appeared right when it should have during that drive cycle that I wrote up trying to start the catalyst test.

I had my Rev300 tune re-flashed just before I went for OBDII test (here in Austin, they do that test) and I failed (that was stupid on my part - I had completely forgotten about the 'emissions readiness'.

Question - how does one tell if the car is ready? I have a scanner but it only will say something about a check engine light, nothing else really.

if the scanner uses service IDs, the test availability and results are reported in Mode/Service 0x1, PID 0x1.

you could just buy a cheap bluetooth odbc scanner and get the torque pro app (pictured in OP) for $15.
