Here is the process I have been using:

1. IGN on (tweecer switch is on #2)
2. load new tune (switch still on #2)
3. IGN off
4. switch to #1
5. IGN on (fan comes on)
6. IGN off again, take key out
7. switch back to #2
8. start car, calcon (kams are all 1.0!)

I gotcha bro

Has this method withstood the (so far short) test of time, or has time uncovered pitfalls or problems? It seems that with this tuning stuff, things thought to be 'true', end up being disproven at some point. :?

I have a wired in KAM switch (that works) that I try to always use, that is if I have the 30mins (or so) to wait. If I'm in a pinch, I'll use the "invalid binary" method presented here. I have not have had any problems, but have only done it 2 or 3 times. I guess I am still sorta worried that there is some "hidden pitfall" or something bad that is intermittent or something.

What is everyones success rate with this method? AND what strategy are you using this on, and what is the calibration used that is invalid (for the KAM clear)? Seems that it only works on some strategys.

For me, I use CBAZA/J4J1 and the invalid binary is A9L.

IMHO I would use the KAM switch....

Note this is just my opinion YMMV.

I have been using it for months on both my A9L and CDAN4 without any problems. I have yet to corrupt a binary or anything of that nature. Just don't use the "update" flag and you should be fine.

My way is easier, have relocated the battery to the trunk, just go out back, push in the batt switch, hold the brake pedal a short time and there you go.

BUT, that also clears all presets in your stereo. :(

True, true, but if you have a loud ex. like mine you won't even have a radio in the car

I'm with pthornton on this one. I have not had any problems with this. I simply download a CBAZA into one of the tweecer positions. Now if I ever want to clear out the KAMRF, I simply flip the switch and then put it back.

It takes a mattter of seconds. Just make sure not to dit while the car is running. I have no idea what it will do. It will most likley just die.

TripleBlackVert · Post by **TripleBlackVert** » Mon May 02, 2005 11:51 pm

i have done it probably 50 times. it works every time, and i have never had a problem.

is it time to sticky this idea?

Dale McPeters · Post by **Dale McPeters** » Tue May 03, 2005 7:38 am

Yep since everyone seems to be having very few problems. I will add a link to this thread in the Software Forum.

Sweetness!
Just got the HP turbo kit installed this weekend and this will definately ease the pain with the new tune. Problem I had was that I couldn't get Kamrf to change from 1.0 and I know the tune is way off, although someone posted that the egr swtiched on may cause this if disconnected. Can't wait to try it.

Guys I hate to bring up an old thread here, and this may be the mother of all dumb questions, but why is everyone disconnecting the battery all the time anyway? Don't tell me I'm supposed to do this every time I burn a tune?

Could this be why my car is running like crap lately? I have been sending tunes to the EEC without disconnecting the battery. Am I supposed to? By the way, I'm with Boss 96 on this, I can't even hear my radio so I could care less about the presets.

JuiceSC · Post by **JuiceSC** » Sun May 29, 2005 7:37 am

Scott, here is the reason. I will use fictitious figures to illustrate. As we tune our cars, obviously adaptive memory builds as we drive with our "tunes". Since it is very unlikely that you can get it right the first time, when you make changes, if you clear the adaptive memory the changes show up faster. The eec has to learn to show us what is going on so we can make adjustments. Since this is a time consuming process, anything that helps to speed up things is a plus. Its really no different than teaching the eec idle strategy after a battery has been replaced. (eec lost KAMs)

I've done it both ways, load a tune with and without resets. Its not that you HAVE to do it, its just a better way to tune. You will see the results of the changes sooner.

Why is your car still running bad? Didn't you get another copy of the base tune I built you? If that worked in the past, it should work again the same way.

This ia related question, so I'm putting it in this thread.

I noticed in the GFUB (A9L) strategy guide that they list the 3 memory locations in the KAM that the EEC checks to determine whether the KAM is corrupt or not. Why not just put a function in CalEdit to set these locations to 255 or something to trigger the fault and KAM reset? You'd still have to key the car to trigger the reset. The better option would to a function to clear the KAM. Any idea why this hasn't been implemented? The strategy guide contans the memory address range.

I mentioned this to Mike already. I'm not sure if it will be in the next release. It is just a matter of finding the correct memory locations.

"Next release"? What's that??? :)

The KAM registers in question are listed on page 22-2 of the GFUB strategy.

KAM KAM
Register Address
--------- -------
KAMQA B80 HEX
KAMQB BC9 HEX
KAMQC BF6 HEX

If it wasn't me, it would have been someone else. Ya can't leave that out there, flapping in the wind. ;)

Clint,
What binary are you loading into your A9* to cause the corrupted KAMRF's?

It was supposed to be mid year. That has come and gone.

Yep
