SD2 Cheat Sheet

[84BuickGNYorkPA]

Hello All,

Finally got the SD2 version 1.1 installed, made up a new cheat sheet for it, very similar to the one I did for SD1. I keep it in the car with the owners manual (TT SD2), it helps me keep track of what each parameter's value was at default (which I let blank since all chips may have different values) what the parameter was set at previously and finally where it's set at now. I had Eric look it over before going public with it, hope someone may find it useful.

Thanks Chuck nice cheat sheet

Great idea, I have it saved and on my desk top. Going with this chip this spring.

Thanks

Cool sheet... 2nd Page has a typo. You have Soost instead of boost

I see your catching on.

I never realized this type of chip was available for our cars. That's why I went with the LT1 MAF and trans +.

I have a wideband tuning system on my Screamin Eagle Sreetglide with similar software capabilities. It targets AFR and gives me full control of the tune. The system logs the data and automatically tunes the map to the target AFR in the map. Once the system has logged its points to the maximum adjustability and can no longer tune to hit the target AFR with in the VE tables it will let you view the data and reset the baseline of the map where it is currently so that it can keep adjusting the tune within the program adjustability.

The key to the whole deal is the base map you decide to start with. Since the Harley have so many configurations a dyno tune is helpful but not required. Mainly to set timing which the program can't adjust.

Since Bob and Eric have a handle on the Turbo Buick the base map should be fairly close but again since our cars are all different you will need to tune.

Basically the two programs work the same but it is our job to get the tune within the parameter's of the softwares automatic fuel adjustments to hit the target AFR.

I talked to you about the SD chip right after you orderd the maf and translater+.

Eric has a video out on tuning the VE tables, all of a sudden a whole new area of tweaking has opened up with this chip, for me.

I remember you mentioning that you weren't using a MAF when I was at your house that day and I knew you were using something more advanced to tune your car but I guess it never registered with me. Once I saw the software and how it worked I knew I had to have it. I've been tuning my Harley this way for 2 years. The only real difference is my Harley tuner will store the new map points and save them meaning if it had to add fuel in a certain cell, that fuel setting will stick so the next time it see's that cell it would have to adjust it again. You then can go to the logs and see the adjustments it has made. Maybe that's something Eric and Bob can add to the PL in the future. This would save a lot of time in the tuning process.

This chip lets me figure what my car likes and what it does not like , all cars are set up different , by the seat of my pants and my ears and nose , I use a afr on idle that my car likes and I use a afr for driving that it feels the best and smoothness and power and the I have 2 settings for ball to the walls in wot afr . Now I have only scratched the surface , now I can go in the ve tables and fine tune it some more that what I had . It does not get any better that that .

 

[psycho6cyl]

this is great!!! im going to buy one asap! even w pl it makes understading tuning easier. i love it.

 

[84BuickGNYorkPA]

Your going to love it, another good thing is that it may be the last chip you buy.... upgrade your injectors? your covered, upgrade your heads, cam and turbo? your covered !!

I cant wait.. I just want to grasp tuning a little more w timing etc and dive into this chip. Pl.made it so much easier to understand tuning bc you can see it happen. Review it and fix it. Not make 3 runs and hope you dont blow a hg..

It's amazing the sheer tuning power available with this new system, with nothing more than a Chip and Powerlogger in conjuction with a Wideband and 3 bar map.
Here's pix of the tables, which you may recognize from the system you use on your streetglide.

The Parameters setup table

The Spark Table

The Target AFR table

The VE Table

And there's even more. On the Powerlogger's data page there are User Tune cells that can adjust larger areas of the VE table if you don't want to adjust individual VE table cells. The user tune cells don't actually change any values in the VE table, but rather adds/subtacts % to them in larger MAP chunks.

The user tune cells don't actually change any values in the VE table,

I would love to see the ve tables change when you adj the cells so you see the real pic of adj you did in real time .

 

[Rafs-T-Type]

Can you use the tune window with the extender pro chip?

 

[TurboDave]

Not that I'm aware of. It's just designed to operate with the SD2 chip.

Yes the Thundermax system I run on the Harley has the same capabilities. It actually replaces the factory ecm and narrow band 02's to the TMax ecm and wideband 02's. All other tuners piggyback the factory ECM on the Harley. The key to this system is the base map you start with. The Tmax will tune the target AFR all by itself but will not tune the timing table. That is why the base map is key. I can change timing etc but once you have a good map it really a matter of AFR and fine tuning. Plus it has some cool features nobody else has.

I will definitely be upgrading to this set up in the spring. I want to go run my car at the strip one time before I make the change. I think I have a pretty good tune right now that with a set of slicks and setting the suspension up right I can run mid 11's from the 12.7 I ran last time out. I just gotta see what I can do with what I have first. Then we go to the SD set up.

 

[TurboDave]

Good plan.

Thanks for the Cheat Sheet! This will come in handy while getting an initial tune.
