Before the Diablo Tune, except for the slight sound change and slight RPM change, I could not feel the transition into 8 cylinder mode. After the tune, I definitely can tell by the seat of my pants when going 4 to 8. I’m hoping there is something that can be done to save the power tune with DoD enabled, but stop the felt surge.

I restored the original backup last night.
I wanted to attempt to log live data from the stock tune and then compare it to a log of live data from the Diablo tune. My download of the log had issues yet again I was able to view it using the Data Viewer, just not save it.
I drove the same way I had with the performance tune and observed one interesting thing. The DoD engaged easier and stayed longer with the Diablo tune. The DoD switch from 4 to 8 was seamless with the stock tune but happened with much sooner.
Once I saw the pattern I kept repeating it to make sure I wasn’t insane, then again my wife would probably say I was for spending so much time playing with this stuff.

Don't forget buying something for her that she loves, just because. Then you will be fine

Now back to the subject. I'm waiting for Diablo (Johan) to reply to my email regarding sugre with the 8r04 tune, from late Thursday afternoon. I'm wondering if anyone else has tried loading the Factory Tune from Diablo? I did and played with the spark advance only. I only adjusted the WOT advance for mid and upper range (+2 to +5) to see the effect on the live data log. I left the low advance alone. In every case the DoD surge issue was present. Makes me wonder what their factory tune was created from? I haven’t had time to reset the parameters of the factory tune, but wonder if anyone else had used it and experienced the surge with that as well. I loaded the 93 tune with out the DoD on Saturday evening. The car felt really good.

Oh well, I'll keep it stock for the time being until they can offer some working solution or at least reply to my email.
Thanks for everyones input and also the link to the artical explaining the inner workings of DoD. The changes to the muffler was an interesting feature to the DoD operation.

or call westers, or vector.
if you call westers, you get the street map that i have in my gxp
if you call vector? umm, no idea honestly.
if you want to keep it simple, the plug n play method works too. but you have to keep in mind, it will be a mass production piece

Alright ...
I'm too busy to mess around constantly w/ my car's computer. I want a hand-held, want a 93 power tune w/ no DoD.
Anyone using that tune? You like it? Gas milage? Should be no surge, right?
Thanks!

I did some reading of the many Q&A posts on Diablo's site. One indicated that the computer fuel usage would not be correct due to the many parameters changed with the tunes and manual calculation would be the only way to get an accurate reading.
I also read one that said that the Factory HP Tune option is the base factory tune that you can change some parameters. If that statement is true then the factory base tune they use also has the DoD surge issue. I tried that tune only adjusting +2%-+5% WOT spark advance to see the live data results and had the same surge as the 93 w/DoD tune. The data log I viewed was also completely different than the original stock tune on the car.

Received an email from Johan at Diablo Sports. He is not aware of anyone else having the surge since the latest releases came out. I'm sending my original tune for his review. If anyone else still has the surge issue since the 8r02 update, you may want to contact Diablo. I'm hoping that it's just not me and joeilesGXP who still have the surge. He was also surprised the Factory Tune has it his comment was: "And why the factory tune surges is very strange as we do not modify anything when loading it.
"
Hope everyone has a great Thanksgiving.

I could probably learn to live with it, but I’d prefer not to as I mentioned earlier most of my normal local travels have me at speeds between 35-50. I found that the changes in grade caused the DoD to go in and out. 8 to 4 is sweet. The 4 to 8 surge gets on my nerves. I may look into other brands but have already spent the money and want to give them a chance. If I wasn't such a cheap ba$tard, I'd leave the Diablo no DoD tune installed. That tune felt really good.

I am operating on the most recent update the one on the diablesport website. and I will tell you I am not having any serious surging issues with it. for your info. I have CAI, MAF and Hogan down pipe with hi flow cat.
