So do I. I mean I do not fault them for the effort. It is just a near impossible problem to solve reliably using the TAC module meant for an 8-pin...

The Factors in his current tune seem fine. The VE ECT factor only changes by a few % around the operating temp (even if running a low temp stat). The...

i disagree with everything except 44281 - make that all 1.0 you can leave the IAT multi and its factor alone for now but being you are running a...

Upload a data log mate so we can actually have a bit of a look at what's actually going on.

Hellcat injectors on SRT would be to small as hellcat is running on 5.5 bar and SRT on 4 bar and that is making all the difference. They will choke...

Edited above to include a log and tune ^.

i just installed the whipple with the 102 mm TB and the issue showed up while trying to to tune it. the 2005 harness the issue started...

you would be amazed if you saw the waste here. some of these people, especially down in newport beach, its crazier than where i live, they throw...

first thing i would do is pull that 102 off and see if the problem remains with the stock 85 in its place *or a hellcat unit if you have one of...

whats the complete build? why did you go with 1000cc injectors? what fuel pump? are you using a BAP? were is the data log and tune file? Help us...

which harness are you using? what did you do about the ESM? other than the addition of the esm for the 07, the 05 is almost the same, wild ...

oh did you change anything between the good and the bad or did it just all of a sudden start randomly going wide open at cruise?

Sure mate I just forwarded both wiring schematic they are almost the same no much differences between them the swap was required due to...

Post your tune and a datalog of the issue. It could be burst knock, low timing in the spark tables, lean or rich condition..

Your going to need to find someone with a TIS and a way to load a GM calibration into the TCM. HPT cant load the whole tune into a new TCM. ...

I loaded 2 more data logs, 1 mild cold start, and 1 with engine at operating temp. The KR goes completely away when the engine warms up, or is gone...

Nice!! I despise XLinks...

I posted a link to it being done but I keep reading other threads and keep finding people buying X-Links and asking me to tune them in the real...

By Jove you've done it! You outsmarted all those engineers! Good work 007

Think someone has a thread on here about that.

That poor engine....

I think he's trying to force it richer and richer trying to get the broken wideband to read something other than 18.0:1.

Why do you want it to run at 12.5 for Stoich? Are you trying to make it run that rich all the time? Im not following your idea here. You...

Thank you blindsquirrel, The 6cyl had the DBW and 4l60 with the PID reading voltage so it kept pulling me in that direction. Car drives fine in 1st...

Noooo... narrowbands for everything in closed loop/EQ=1.00, and wideband for open loop/PE. RPM has nothing to do with it.

So I scaled up the preignition and cylinder pressure limit. I'm still getting this oscillation under moderate acceleration. I don't see anything...

hi has anyone found a solution for the rev hang/reving on its own.....
