Option to delete SES light triggers for cat delete

rjd598 wrote

sorry to thread jack but does the delete-r allow the car to throw actual engine codes if something were to happen?

Yes it allows other engine codes, it only blocks the O2 readiness codes. Personally, I don't think it can be beat for ease of install, reliability, and quality for those of us looking to run OE tunes.

Will it allow obd2 plug in readiness inspection? Readiness fails if codes were recently cleared.

It will fail readiness. There is no "have your cake and eat it to" solution for this car as far as I know. If your running no cats or cat delete, your going to have to re-install them for SMOG in CA.

My BMS DP Fix works. Passes readiness. Obviously nothing can pass a sniffer test except maybe HFC.

I can't seem to get my hands on one of these. The delete-r is $400, might as well get tuned.

It's better to get a tune anyway because it's not a band-aid like all of the other potential solutions. On top of that, the car will run much better de-catted with tune, putting aside the SES light woes.

The Delete-R is constantly checking and then clearing the cat efficiency faults, and clearing fault memory automatically resets readiness monitors.

Under those circumstances, I would get a tune.

Thanks Mike, I've heard nothing but good things about you guys so I'll be in the market soon.

Thought I'd follow up in this thread:

Mark@Evolve ( Evolve-US on this board) reached out via PM and offered to give me exactly what I wanted.

They sent a cable and I installed their software on my windows laptop. I actually had trouble with that but Mark provided stellar support resolving the issues with my laptop via online remote control with a software called Teamviewer.

I then downloaded my ECU file and emailed it to Mark. I received my software file back very quickly and with only the cat delete done; all other parameters remain original.

I've since piled up the miles and did some track days and no SES light in sight despite my awesome Macht Schnell test pipes

I couldn't be happier with the service and support, I urge anyone who seeks similar service to contact Mark @ Evolve








And for your viewing pleasure

^^^ Is the catless only tune cheaper than the regular full N/A tune?

I would hope so.

so what is the difference between a module clearing a code and a tune clearing a code?
if a module checks for codes and clears them, what does a tune do? can you tune a car to show the o2 sensors are working fine?

Either way is fine as long as readiness is preserved so you can pass OBD2 inspection. My understanding is that the Akra Delete-R does not preserve readiness so you will not pass OBD2 inspection. You just won't have a light on in your dash. The tune, on the other hand, or a simulator like the BMS DP Fix that is no longer available and that has a mixed reputation for being effective on these cars, will preserve OBD2 readiness so you can pass OBD2 inspection.

What does a tune with o2 fix only vs an actual tune cost?

Much cheaper. I went the same route with Evolve and got the o2 fix only as I wanted to stick with the OEM tune etc.

PM me since I'm in GTA as well.

The Stage II offroad software doesn't clear anything, it prevents them from being triggered. The o2's will work fine and are not disabled, unless they are unplugged.

Is there a way to "tune" or program the O2 sensors to show ready to pass Cali smog? I'd be very interested in that.

Plug in but not sniffer test can be passed.

OP, I thought you got rid of the E9x for an E36 for the track??
Welcome back! Car sounds SICK!

A standard tune just disables the ability for the ecu to trigger a CEL because of the catalytic converter inefficiency but it does not set O2 readiness for smog. Tuners have the ability to force readiness but most won't because technically it is a felony. Without O2 readiness you will not pass a plugin test.

The tunes pass OBD2 plug in. They pass readiness. They are considered off road tunes, which means they are not legal for road use.

I wouldn't be surprised if you can get tunes with readiness already set, but based on what I've read on here that is not standard. That being said, I don't have a tune so I can't speak from first hand experience.

Any software that turns off the post-cat o2 sensors will cause an automatic readiness fail and will not pass smog. However, cars that require this would not pass regardless due to the cat checking of the stock emissions programming.

Any car that has software whether its Powerchip, ESS, Evolve, Dinan, etc.. will pass smog as long as this function is left turned on. Stage II software normally has cat delete and they will fail the on-board test although they may past the tailpipe test.

If you have cats which are borderline CEL, you can squeeze by if you avoid prolonged drives on the freeway. This goes for tuned cars and stock cars.

Mike Benvo wrote

Which part of the test did it fail?

Normally when the cat efficiency error is ignored in the ecu file, this prevents the readiness tests from leaving the "pending" or "not ready" states, which will cause an automatic fail in states that read the OBD monitors and require them to be ready.

There are some tricks to get around this but it's shaky territory in terms of federal emissions standards.
