Can do!

Cody and Bill. You guys moved a lot faster than I thought you would on this! Kudos.
I got the RMA number in the email.
I have a trip planned in three weeks and I don't think that the shipping back and forth will give us enough time.
I will send it back the last week of May. I don't have any towing plans for a while after I get back then and it will allow plenty of time for all.
Thanks for all this and I will definately do this, but for today I have to wait.

OK, I'm pulling the chip right after this post to box it up and send it to you for a reburn.
Please repost those pictures from Photobucket so that I can review the tuning and tell you what I have in mind.
Also, I still have that RMA number, but have no idea how to use it.

Kwikkordead Wed, July 7th, 2010 07:38 PM

OK, chip is out.
Also, I'm assuming you just need the chip and not the switch with the wiring harness?

Dan,

You're correct. We don't need the switch.

As for the RMA#, just write it down and throw it in the box with the chip when you send it.

I'll get some more pictures up in a few minutes.

The idle could easily be raised a couple hundred RPM in this tune as well.
What program did you want to replace in order to run this one?

For the most part, you could always leave the idle stock and use this tune....it's not going to advance the SOI farther than stock after 1300 RPM or while the oil temperature is above 80*C.

That's what I was thinking too. I always keep my foot out of it when it's cold so it would easily be a drivable tune.
.
What I have in mind is to have this tune in the first position, then in position 2 have the basic stock tune, moving the high idle tune to where the "smoke show" tune is now. I can belch a black cloud with the 80 hp tune just as thick as the smoke show whenever I need to.
The only other changes that I would like to make is to lower the idle for all the tunes except the cold start down to 600 or whatever the stock idle speed is, whichever is lower.
I spec'd 650 last time and I don't like it, too fast.
I would like to set the cold start tune to 700.
Do you have any objections to having the values be the same from zero degrees all the way to 60 degrees at both 600 and 800 rpm or would it, in your experience, be too much advance?
I'm just a little nervous that 2 degrees change of advance won't be enough.
.
So the order of tunes that I would like this time around would be:
1=cold start, 700 rpm
2=stock, 600 rpm
3=25hp tow, 600 rpm
4=45hp tow, 600 rpm
5=80hp driver, 600 rpm
6=1100 rpm high idle with no cold start SOI.

No problem, Dan. I was simply posting a picture to give you a general idea. I think that we can comfortably get away with 4 degrees....any more than that, and I'd rather live-tune just to make sure it's not too much.

As for the idle speed....no sweat! :cool:

OK, I'll get the chip mailed off today.
Thank you very much.

I've been digging around the website for a long time now and cannot find the address to send the chip to.
