I have a question for all the people that are running this tuner in performance setting. I was traveling to the north on I-79 and US 19 and noticed a problem with my cruise control while freewheeling down the other side of those hills. I am wondering if any one else with an auto and the tuner has experienced the same thing. The truck was pulling the grades fine but when coming to the top of the hill and coasting the other side the truck would continuously buck, (accelerating and decelerating very fast to get that bucking sensation) so, I am wondering if anyone maybe from WV area has encountered this problem with the tuner?
If it is a software problem I was going to get hold of the manufacture.

Than for any input on this matter.

what software version do you have in the diablo

 

I loaded the newest version r22 just before I left. I figured there may have been a download problem and pulled the program out and used the stock program for a couple of days in Western New York, but it started again after loading the program. Mmm makes me wonder, I will give the thread a few days to see the responses I get before contacting the manufacture.

Morkable, explain is this another box type? And did you have the mimic of what I described. It may also have to do with the stepper motor in the speedo drive because that baby is humming like a bird, real annoying!

no, mine didnt do that,, just would surge when I installed bullydog triple dog

Same here. One of the main reasons I went looking for a new programmer myself other than the Bully Power Pup. HAd the surging prob. No prob whatsoever with the Diablo tho.

 

I run performance all the time. No problems using cruise. No problems at all. Just good smooth power...

 

Well here is the answer I got from my question:

"I have seen that as well, that is simply due to the added fuel and timing in that area and unfortunately it does reflect under cruise mode under higher load levels. The low hp tune should not be as severe but I have not found a way around that at this point."
