Anyone in NOVA running catless and with the SAP delete?

My car is registered in NOVA and I am running catless on my E46 M. I already have my O'2 is a ready/passing state so I can pass emissions.

However I am planning to do my SAP delete soon and will need to have that put in a ready/passing state as well so I do not get a CEL light.

My question is... is there anyone in NOVA that is running catless and with a SAP delete that has both sensors in a ready/passing state and not had any issues passing emissions?

I did some searching and all I found some states only allow one sensor to be in a ready/passing state. I do not know if VA is one of those states.

If I won't pass it's not worth it for a few lb's of weight savings and a cleaner engine bay.

Thank you

How about either?

Anyone running catless or with the SAP delete?

I know someone on here from NOVA has to be doing either if not both..

My 01 330ci passed emissions inspection with SAP delete.

on M3's deleting the DTC's for post 02's set the monitors to ready.

So in essence deleting the DTC's for SAP, and POST 02's it will pass.

Let's start by learning how to identify a DTC string within the DME. A firm understanding of the DTC errors and their respective codes themselves will be of great assistance. NikolaiD has posted an excellent reference/list that can be located here.

Once you have an idea of which DTC you'd like to suppress, it's important to understand the actual binary string within the DME that represents your DTC. These strings are not located in the same position in all binaries. I'll do my best to provide a list of each DTC and location within each version, but will probably only start with the most commonly-suppressed DTCs for the time being.

The string is 14 bytes long, and generally starts with the hexadecimal DTC code itself, and finishes with a 'FF' terminator. For example, if we look at NikolaiD's chart, we can find that code 170 (AA), 'Minimum flow of secondary air', which is most commonly associated with the secondary air pump delete, has a code of 'AA'. Thus, within a sample 211323002501JD79 MSS54HP DME, we find a 14-byte string at offset 0xE3BE representing that particular DTC that looks like the following:

Code:
AA 01 01 01 01 01 01 00 01 02 03 28 27 FF
METHOD 1:
The first method, and coincidentally also the easiest, I'll mention is the one that I believe to be most appropriate (I reserve the right to change my opinion).

To suppress this DTC, simply alter the string by replacing the 13[sup]th[/sup] byte with '00' as follows:

Code:
AA 01 01 01 01 01 01 00 01 02 03 28 00 FF
METHOD 2:
The second method is to actually zero out the entire 14-byte string as follows:

Code:
00 00 00 00 00 00 00 00 00 00 00 00 00 00
----------------------------------

Regardless of which method you employ, the DME's errors must be cleared after reflashing the DME with the updated binary.

You're best off turning off the error codes you want to turn off. It has been reported that 0'ing out the entire string for the cat efficiency codes sets the monitors to ready.
