Yup. For me I have to pull the cluster bezel, and lower dash panel (below steering column) to get to these fuses where the brain for the remote start is. Pulling the radio fuse at the main box under the hood works form the aftermarket HU, but also have to pull the remote start fuses. Took about 2-3 weeks to figure that out after trying to send data logs to BBP.. I need to add some length to the power wires for the remote start, for easy access and a q/d of some sort. Although, I don’t really want those being very easily found either.. [emoji107]
That sux. I have both also.

Back to working on the tune, Not sure if its weather-related or what but I could swear I had the VE table much better than this! how can something be 2000% lean.

First log before any changes

After a massive fuel add to the VE Table.

Obviously still alot to go but it always takes time to iorn these things out. At least now I can do 5 or more revisions just in my daily routine.

Also decided to do some legit research on what the coilovers should be set at, I had both compression and rebound at 10-10 which is a no-no apparently. So Per their instructions I have them at 4-8 right now. Might need to go a tad stiffer but dang it rides even better being soft.

Recommended baseline points for adjusting your Viking shocks are as follows:
Ride Quality/Street:
Front: 1 - 4 compression; 4 - 8 rebound
Rear: 0 - 3 compression; 2 - 5 rebound

you prob shouldve done a full multiply by % to reel it in from the get go.

or keep doin what your doing and just highlight the 400 and 800 columns from .50 down and add 10% (multiply by 1.1)

I actually did a full % multiply on that one because it was so jacked. I was expecting a little better results from that, maybe it just needs more work, I think if it reads over 18 then it logs it as 18 no matter what so there could be some issues with it not reading high enough to get the full correction until I get it closer.

2000% lean lmao,
if youre logging with the key on engine off it hits the cell a bazillion times with zero fuel...but it should be at 101kpa or so though, what does you map sensor read with just the key on? engine not running

some gen 4 goodness, been messing with IAT vs VE table to try and smooth out the temp swings from 120* intake temps down to 40* intake temps. not sure what i did but took a little too much out of it

One of these days I’m gonna get serious about learning this shit. I’m appreciate you taking the time to explain things and give examples(in your thread and others). Also, thanks @Dantheman1540 for doing the same. I really struggle with keeping focus in the computer department

Red is a whole lot scarier when you know there's a Wuhan War Whistle begging to break stuff. :eek:

I'm with you I feel like I've wasted so much time and money on tuning stuff and I still hardly know WTF I'm doing lol. Posting always helps me actually absorb and workout what sin my head. Sure I look like an idiot sometimes but it helps me a ton. My goal with everything I do is to be able to teach someone that has little to no knowledge of the subject to be successful in doing the task on their own. Teaching is one of the most effective ways to learn and the only path to true mastery.

I have a buddy that moved to north port Florida about 6 months ago. I’m not sure how close you and @randeez are to that area but if I ever venture that deep into Florida man territory, I’d like to meet (or meat) up with you guys

tune at your own risk.... lol

yea its intimidating at first, one of the worst things for me is "knowing" what i want to change but having no idea what table to make the changes too...i've spent days literally just googling "hptuners e38 XXXXXX table" because some of the descriptions dont make sense, or are called a multiplier but they work off of cam rotations not standard rpm, or whatever. ive messed with a table i knew is what i wanted to do for ever and had a hell of a time just to find out higher numbers meant it went down lower numbers mean it go up.... its not that its wrong - its just how hptuners interprets and manipulates the tune and how it has to be done

I bought hpt in late 2011 when I did the ls swap on my c10. I spent months reading. I found out that there’s 50 different ways to get the same results. No one does anything the same way. I got overwhelmed and just gave up.

Randy is just on the opposite shore but not to bad of a drive I don't think. I'm about 2.5 hours away according to the google, not far I'd totally do a meat up sometime.

I haven't broken anything by tuning..... yet..... *****knocks furiously on wood*****


I know the struggle! Trying to figure out how to word a search when looking for info on HPT is very difficult. Gen 4 is a whole different animal I'm glad I'm dealing with the simpler stuff.

I spent about 2 weeks everyday after work trying to get my buddies 408 denali to stop stalling and stop having crazy rev hang in neutral while rolling. Every forum post said adjust throttle follower and throttle cracker. I did the same thing with adding not subtracting and then finally went back to a stock file and realized everything I did made it worse and it was actually the base idle airflow that was all jacked up. That truck was so messed up even after that the only thing that fixed it was loading my Tahoe tune in it and starting from that.

Have either of you guys figured out the real time tuning function? Back when I was reading, they said that you could log and overlay the corrections. 3-4 times of that and you’d be 99.9% set. Obviously the more you did it, the better it got. For something like Randy’s truck, it wouldn’t be optimal but for a simple drivability tune, it seems perfect

no RTT with gen 4 stuff

on the older stuff i think you had to select which tables you wanted to use for the RTT

I remember hearing a ton about the RTT before I got HPT now I can't remember the last time I saw anything about it. Its certainly not mentioned in any tuning videos I've watched. Haltechs have a sort of RTT and it works great on my buddies rotary.

got a friend over in st pete/largo i usually stay with over that way...been wanting to do some more stuff at bradenton track (streetcartakeover this weekend) im just beat....the drive over sucks usually

I've only been down there once for a cleetus and cars. I haven't been to a race track and race in 6 or 7 years. I'd like to start going but I need something besides my DD to race lol.
