The manipulation codes aren't standard OBDII codes. They don't show up on normal readers like that one.

True. It doesn't show the code but it does clear it. A friend that is a BMW mechanic uses one when he needs to clear codes quickly instead of tracking down the factory BMW unit. I confirmed it with my BT.

So you're saying you read a manipulation code with the BT unit, and then cleared it with the Sears unit, and were able to verify that it was gone?

Which manipulation code did you have?

I read yesterday that a 335 threw a code because the brake was pressed at WOT doing a burn out. The car knows all scary stuff

I've the JB3 v1.1 then upgraded to v1.22 and I just scanned my car last night and found the 2D25 code. I've emailed Terry, he suspect that it's probably from v1.1 map (I ran the high boost map when I've the v1.1). I've cleared the code, gonna scan it again after I put my JB3 back in.

Anyone who has a tune should get the BT Scanner (or whatever that can clear code). For ~300bucks, it's a good investment.

That is correct. I read the code with the BT unit, cleared with the Sears unit, and confirmed with the BT unit.

I had the 2D25 code.

Interesting. I'd love to know for sure that the BMW units can't still pick it up if they start digging, but that's good news either way.

since it records pretty much everything, does it also record each time it is cleared?

Just scanned using the BTT and found this code 30FE with this kPa amount 186.00 and another of 165.00 in front of the throttle valve. which if these are 'kilo pascals' this is 26 and 23psi respectively. A tad bit high if you ask me. I have JB3 and LOVE it.


EDIT: I'm retarded! I looked it up a bit more... I now realize that you take 100kPa and subtract it from whatever the total amount the ECU logged. Whoops.

Anyways that is about equivalent to 97.6 or rounded to 100 Kilopascal.

That is the ambient air pressure before boost is applied.

You then subtract the pressure reading at throttle valve of 167 kpa and you get:

167 - 100 = 67 kilopascals of boost above normal atmospheric pressure.
If you then convert the 67 kpa to psi you get about 9 psi of boost pressure above normal atmospheric pressure.

So Mike was right and I was wrong.
