Did you read the rest of the thread? Mine as well as two others have had a problem with the mds switch- which was solved by you uploading a tune with the mds off.

So I loaded the tune and ran it as it was (I don't think it had any options) and it did turn off the mds.
So if my Diablo isn't turning off my mds with the factory tunes, is it even tuning my car at all? Why wouldn't it turn off mds the way it was written?
Thanks

I will try that. I have made a Youtube video (I apologize its not too interesting) when I went out to get the tuner- this was the same tune I sent yesterday, then I tuned it again to Diablo tune. You can see if it's going correctly. It tells me it's tuned with mds off. If it's not turning mds off ...

Thanks. I have tried modifying the stock tune with MDS off, the Diablo tune with mds off, and now the 91 octane tune with mds off. It goes through the entire process, and at the end says the tuning was successful.
I posted once before to make sure while choosing the mds toggle is supposed to be off ...

it's too bad- you get one tech and they're more than happy to help, next time you get one that's just a smart ass. He could have looked at the file and told me something constructive- but he didn't. Maybe I'll just write an editor and edit their files myself

OK so you've been a huge help. I guess when people ask me about Diablo I can just tell them good luck- it's a pretty 600.00 set of gauges.
Sorry to bother you.

It tests them on start up and they are fine, something happens while I'm cruising that it tries to slip into mds then back out, that's when it throws the code. It takes about 5-10 miles or so for it to set the code.
If there were a problem solenoid you would think it would NOT want to try to go into ...

Regardless, if the system is turned off it doesn't know if the solenoids are working properly or not since it's not trying to activate them.

I just updated my T2 today, still have symptoms.
The car "surges" while I am driving, mostly cruising. It seems to be kicking in and out of mds, after a while I get a P3497 code. I have my MDS off and I have tried both Diablo and modified stock tunes with the mds turned off.
I have read where ...

Nevermind- found it. DUH I was looking too hard at this!

Hi! New to Diablosport- maybe I'm missing it but I can't find out which computer program and how to load a custom tune to my Trinity T2 EX.
Thanks!
