Hi all,
I'm completely green to HP Tuners, and Chryslers for that matter. Only owned GM's previously, 3 GN's, Impala SS, a bunch older of trucks. I do have very limited experience using FAST XFI on my last GN but it had a pre-built tune and it was self learning so it basically tuned it's VE as boost/conditions changed, not much knowledge needed on my part.
Background on the current car, it's a DD 2006 Chrysler 300C SRT8 6.1 74k miles, newest vehicle I've ever owned lol. Very minimal mods, intake, cat back exhaust, 180 thermo. I had a Diablo CMR tune and installed a tuned TCM from a tuner (EGS53 TCM). I wanted to take things into my own hands vs having to email a tuner or send the TCM out for adjustments everytime. Plus getting a dyno tune would be very unlikely, since I live in Hawaii and tuners are very limited so it made sense to be in control of the tune.
I pulled the CMR tune and left the EGS53 TCM connected, unmarried the diablo and returned PCM to stock and reloaded the previous setup in HPT format. I did get to take a log last night, nothing too crazy, just wanted a base line of what state the cars running in. And was hoping to get some advice on any changes I should make and if anythings way outta whack?
All I really want to achieve right now is to optimize the current setup, get comfortable using HPT, and have a real nice driver. I'm looking to improve on part throttle performance if possible being this is where I spend most of the time, and I feel like there's a bit of a dead spot in the power band from about 2000-3500 rpm. I know some is attributed to these cars making power up top. Eventually I may install a cam but I'll cross that road later with tuning, I want to at least know what I'm doing before that. I do have a AEM WB that I'll be installing but still would be waiting for the MPVI2 upgrade release to log AFR.
I also had some questions:
1) What other Channels should I be logging?
2) I'm not sure what graphs and charts should I setup while logging, to effectively adjust the tune?
3) Based on my log, I made an adjustment to the VE table... Is this the right way to dial in the tune? I copied and multiplied by % half.
4) Looks like there's a few degrees getting pulled from timing up top, I was thinking of lowering 5 deg from those areas.
Any advice will be greatly appreciated. I'm trying to read as much as possible, I'm assuming being pretty close to stock it shouldn't take too long to get dialed in. Thanks everyone!
