DDM's Latest Tune

Quote from LargeCar

Just to be clear in case my other post was not. I did not have the rev hang before the Bob tune, only after. I have no issue with Bob or his work. Just something has gone goofy and some if us are getting the rev hang. I'm sure it will be corrected in the next tune. When Dave and Bob put their heads together only good things will happen. Be patient little grasshopper and good shall reign.

Please keep us posted - I am watching this with great interest. I plan to do the Bob tune this winter but will wait to see how your rev-hang, and the others' is resolved.

no rev hang experienced here and about 5200 miles since tune applied

I had the rev hang before Bob’s tune. Dealer reflashed and it was gone. After tune (and SC) mine revs high when starting and quickly drops to normal.

Is the new tune "for sale" yet, or is it still in test? I have the rev hang with a supercharger and would love to calm it down. If available now, do you buy it through DDM (e.g. buy the shipping envelope etc like with the charger), or direct from Bob's tune?

Thanks

Bob and I have swapped emails. He wants to put my ECM in another SS to see if he can reproduce the rev hang I'm experiencing. @BryanL is going to let me use his ECM so I can verify for myself that it is the tune and not something on my SS.

It will be nice to hear your findings. Bob is a stand up guy and great at what he does. I just purchased the DDM supercharger so I'm sure my rev hang issues will be eliminated once I obtain the new SC tune. Either way keep us posted.

I did the ECM swap with @BryanL. My SS ran great with his ECM in it while my ECM in his seemed to act like the OP's. @BryanL indicated that he thought it acted like his Harley when it was too lean. Backfiring on deceleration and some on acceleration and seemed to be flat. I will say we only covered maybe 20 miles so maybe that was not enough learning time for the ECM. Still sending info to Bob and will be sending ECM to him this Friday.

The new tune update for the supercharger kits is not available yet, we are doing some more testing on it before releasing to the general public. The tune and payment will be made through Bob directly, once we give him the go ahead to release it.

Bob is a great guy and definitely cares about the customer and making sure it is right.

Sorry, for the late reply, I was out of the country for about a week.

Looking forward to your results!

Bob told me 50 miles min. before really pushing the SS. I did not make it because of rain and the next day at SSITS16, OH WELL! was following @rabtech and now you know the rest of the story. He could not get away from me on the Cherohala Skyway. Except on the straights.

Thanks for the reply @Dave@DDMWorks left a message with Angie. Will need to speak with you regarding the tune, pulley size change, and a couple other misc items. Happy to hear your back in the country and had a safe trip.
