Concerned and aggrivated
First let me say that I am not making this post just to hear (see) my self talk.....I have been having this problem as well as many others have from day one of installing my COS.
This is the OS I am running: 03190003
I love the versatility and abilities this COS gives me with my SD tune save one HUGE problem.......extremely large Lean spikes on throttle tip-in. I see anywhere in the range of 1.35 - 1.55 BEN factors when hitting the accelerator. When i go WOT, it will actually bog for a fraction of a second until it can recover (5 or so frames later). I was about to purchase the road runner but am waiting for a resolution to this....because to be honest.....the thought of crossing over to other software has crossed my mind lately. Everyone i talk to on the other side does not have these issues when running a SD tune. Lean spikes of this magnitude are a REAL concern to me. I could always go back to closed loop, but i bought this software, spent many hoours learning and tuning, and want to be able to tune my truck the way i should be able to. The first major concern of the COS (which is now a stickey in this section) was the ECT issues at start-up...this was resolved very quickly and updates were posted. I think this situation warrants the same attention. This problem has been brought up many times, most of which were done in private meassages and I would really like to at least see some discussion on a resolution.
I am providing a copy of my tune and a log for that tune so you can see what I am talking about. I know this is not a tuning parameter that is incorrect, this has been confirmed as a COS issue. Please help me to resolve this. Acceleration enrichment tables have been discussed as a resolution to this issue. I understand that this tune is not "spot on" by any means, but this does not account for the terrible lean spikes observed (and felt).
Thanks,
Jimmie
